Main types and advantages of PET bottles

Product types

The classification of PET bottles is based on several parameters finished products. The main ones are the following:

• light transmittance. The container can be transparent, darkened, matte. In the first case, it is used for bottling lemonade, juices, and vegetable oils. In the second - for the sale of low-alcohol drinks, balms, tinctures of medicines. The purchase of opaque plastic bottles is most often relevant for manufacturers of household chemicals and car products.
• Wall thickness. It is selected depending on the purpose of the container. If bottles made from PET will be used to store non-aggressive substances, then standard products (0.1-0.5 mm) will do. household chemicals need to be poured into multi-layer containers containing a polymer. For highly carbonated drinks, containers are produced, which include nylon (passive barrier). In the case when you have to work with reagents, you need PET products that are resistant to UV rays (active barrier).
• Volume. Plastic bottles vary in size. You can order capacious containers or buy small PET bottles.

Benefits of bottles made from PET

This container is very convenient for storing and transporting liquids of almost any kind. The basis for the manufacture is polyethylene terephthalate, a material that is now actively used for the manufacture of containers in which both drinks and food are stored.

Plastic containers for liquids are in high demand, which is explained by a number of its advantages:

• Ease of use. During transportation, the probability of damage to PET bottles is minimal.
• Variety of forms. The practical application of modern technologies makes it possible to obtain containers of various designs. Preforms are used (PET bottles are blown) or the extrusion method.
• Branding opportunity. Labels and other promotional products can be glued to the surface of plastic bottles.

We have been producing PET bottles for many years, we can fulfill orders of any complexity.

What determines the price of PET bottles?

The pricing factors in the sale of PET bottles are:

• volume;
• features of the used PET (regular, multilayer, etc.);
• complete set (presence/absence of cover and handle);
• order specifics (small, medium, large wholesale).

Plastic bottles are needed for packaging juices, mineral water, soft drinks, beer, soft drinks. Given the consistently high consumption of these products, the need for packaging will continue, as will the demand for equipment for the production of PET bottles.

The industrial production of plastic containers was established in the 70s. The revolutionary discovery gradually supplanted its glass competitor. And today, plastic containers are on almost all shelves of retail outlets.

This trend is due to a number of factors:

• The PET bottle is very light. For example, a glass container with a capacity of 0.5 liters weighs 350 grams, and a plastic counterpart is only 28 grams.
• Variety of shapes and colors. Transparent plastic is easily painted in different colors, emphasizing the content.
• The presence of a mold of individual design allows you to produce containers of the desired shape.
• Doesn't beat.
• Low-cost production guarantees low-cost products, which compares favorably with glass.
• Conditions for recycling.

With all its advantages, a plastic bottle is not without its drawbacks:

• Carbon dioxide leaks are observed, the situation affects the quality of kvass, sparkling water and beer.
• Plastic does not interfere with the penetration of oxygen and sunlight. From this, the product loses its properties and is stored less.

Raw materials for making bottles

The basic raw material for the production of bottles is polyethylene terephthalate (PET) or thermoplastic. The material has the property of polymerization when heated, i.e. the ability to create larger structures at the molecular level. When the desired viscosity is reached, the composition is cooled to prevent the reverse process. By polymerization, the raw material increases significantly in volume.

The strength of PET containers depends on the quality preparation of raw materials, it is necessary to remove moisture from it before molding.

The resulting marriage is immediately sent for recycling. Thus, production works without waste. Multi-colored products are obtained by introducing a dye.

How bottles are made

The production of plastic bottles is carried out using injection molding technology.

The initial stage consists in the formation of blanks - molds. To do this, the granulated PET feedstock is exposed to high temperatures in order to obtain a homogeneous bulk mass.

The mold has thick walls, small size and finished neck. Molds may vary, which is necessary for the production of bottles different forms and sizes.

Then the blanks are delivered hot to the blow molding machine. The bottle is formed under high pressure of 30 atmospheres into steel molds. Their configuration is standard or original.

Air under pressure enters the mold through a steel rod to evenly distribute the composition along the walls. It is important to ensure uniform pressure throughout the volume, which happens if the process is made very fast.

The use of high pressure for the production of containers makes the process highly productive. A bottle of the required size and shape is produced with minimal time.

Compliance with the technology will allow you to get a smooth product without deformation.

The concave bottom with a bulge at the bottom ensures the stability of the bottle.

The next production cycle involves cooling the preforms using liquid carbon dioxide, air or water.

The finished container enters the control point, where the bottle with signs of deformation is removed for recycling. The marriage is sent to the line for grinding recyclables. High-quality products move on the conveyor to the workshop for packaging.

Bottle production equipment

There are two types of plastic bottle production lines/

Single-phase - obtaining a mold, blowing bottles takes place in one place. The process occurs while maintaining the mold in a heated state.

Two-phase - production, blowing containers, is carried out at different points of production. The mold obtained on one equipment is transported by the operator to the blowing line and loaded into the machine. During transportation, the blanks cool down, so they are reheated in the blowing machine.

The automatic line includes the following equipment:

• PET platform;
• heating oven;
• quartz lamp;
• blowing machine;
• double mold.

On the PET platform, molds are created using the technology of thermal heating of granules.

Specificity

Molds are heated in a conveyor-type oven. Eight zones of active heating evenly heat the workpiece, so that when blowing a high-quality product is obtained and less wasted. The equipment must rotate the molds for uniform heating and move them. A quartz lamp warms up the molds in the oven.

Blow molding machines are produced for the manufacture of containers with a volume of 0.2–5 liters, as well as 5–20 liters. On the aggregates, the soft base is inflated to the required size.

Hot air is supplied at a high speed to ensure that the bottle has the correct shape without flaws. The air supply comes from the compressor. Additionally, the machines are equipped with sensors to control the heating of the threaded neck.

A double mold made of high-strength steel forms the appearance of the future bottle.

When choosing equipment for the production of plastic containers, take into account:

• bottle volume;
• number of zones for heating;
• blowing pressure;
• power and performance.

For the production of plastic bottles by drawing with the use of two-stage blowing, equipment A-1000M3 is installed.

It has a capacity of about 3 thousand bottles per hour in the production of containers with a capacity of 0.25–2.2 liters.

The equipment includes a loader of molds and blanks, a heating unit, a power plant and a manipulator.

Equipment of the MB series, operating in semi-automatic mode, is designed for the production of containers with a capacity of up to 5 liters. The composition includes a heating device and a pneumatic shaper. The equipment for the production of plastic bottles using the “heating, subsequent blowing” technology is in operation.

Where is the best place to install the equipment

To install a line for the production of plastic bottles, the area of ​​\u200b\u200bthe room must be at least 30-40 m2 with a ceiling height of 4 meters. The floor and walls are made of concrete or tiled. Other non-combustible materials may be used.

The production of PET containers is associated with harmful fumes, so the ventilation system must be thoroughly thought out. Additionally, you should take care of connecting the water supply and sewerage, which are associated with the production cycle.

The workshop must be equipped with three-phase sockets designed for a voltage of 380V.

When organizing a production site, it is important to comply with fire safety standards for productions of this type, where a furnace operates with heating up to 200 degrees Celsius.

Production of PET bottles: what you need to organize an enterprise. Calculation of necessary costs, business profitability, marketing risks.

Capital investment in business: 565,000 rubles.
Payback period for the production of PET bottles: 12 months.

Every day more and more new drinks are released, and each of them in its own exclusive bottle.

Almost all soft drink containers are made from plastic.

This material is advantageous and convenient in that it has a low cost, but at the same time it is quite light and durable.

It follows that production of PET bottles- This is a fairly popular and profitable business.

Of course, it is worth considering such a moment that it is much more profitable for large firms to produce them themselves.

But there is a small trade in branded drinks in some establishments.

It is these customers who most need PET bottle production services.

By owning such enterprises, you can consistently make big profits.

Possible risks of opening a business

Among the risks are:

• lack of markets;
• rising prices for raw materials;
• long payback period;
• low level of profit in the early stages of work.

All these factors can negatively affect the profitability of the enterprise, increase the payback period, and in the worst case, drive it into a minus.

How to prevent possible risks?

In order not to go bankrupt in the first year, it is worth taking care of the sale of products at the stage of purchasing equipment.

The sooner the product starts to sell, the sooner the profit will come.

You should never rest on your laurels: always look for new customers and collaborate with other businesses.

In order not to lose much on a sudden increase in the price of raw materials, you need to establish relationships with different suppliers, and buy different types of raw materials from different firms.

Different materials can be beneficial to buy from multiple sources.

In order not to lose heart if the profit received is lower than expected, you need to have endurance and additional capital for safety net.

It would be nice to attract investors to expand the business when your PET bottle production starts to flourish.

Conclusions about the production of PET bottles

From all of the above, it follows that in order to organize production of PET bottles, you need not so much start-up capital.

The main costs will go to equipment.

According to experts, the profitability of such a business is quite high, but only if organized work enterprises.

In addition to the main risks, you need to monitor the quality of products.

Since even with well-established sales markets, no one wants to buy a low-quality product.

The most important thing is that the entire container is of the correct shape, and does not have a pungent odor.

You can expand your business by producing eco-bottles.

They are beneficial in that there will be more demand for them.

They harm the environment less, and this approach to life is now “in trend”.

The essence of the environmental friendliness of such PET bottles is that the wall thickness is slightly less than usual, due to which they are easier to recycle.

And the smaller the thickness, the less material is needed for manufacturing.

This is already beneficial to the entrepreneur himself, as it will reduce the cost of raw materials.

Nowadays, plastic bottles are an indispensable package for beer, kvass, water and many other liquids. The main material for their production is polyethylene terephthalate.

Today, even in small settlements enterprises for the production of beer, soft drinks and food products are often built and successfully operate. But in this area it is impossible to do without plastic containers. In this connection, almost all manufacturers have no other choice but to buy plastic bottles from other industries at high prices. However, if you delve into their production, we can conclude that the process of their manufacture is not something abstruse and impossible. And if you look at the technology and prices for equipment for the production of plastic bottles, you can forever exclude the purchase of such containers “on the side”.

Equipment for the production of plastic bottles

Naturally, producing any materials on your own is much cheaper than buying them from manufacturing companies. And plastic containers are no exception. In fact, the organization of production is a fairly easy process. As in all industries, the production of PET containers will require special equipment. It can be divided into the following groups:

• preforms;
• Bake;
• Quartz lamp;
• Blowing machines;
• Double mold.

Preforms are a special basis for the production of bottles. They are produced using polyethylene terephthalate granules by forming their shape under pressure and high temperatures. Such bases for containers, in turn, can be divided into the following types:

• Universal;
• Thick-walled;
• Shortened.

Making plastic bottles with various kinds preform allows you to get a variety of bottles that will differ from each other in shape and color.

Bake for the production of PET containers is used to heat preforms to the required temperature. Additional options of such equipment include the rotation of the workpiece and its movement, which provides more effective softening and, as a result, ease in giving the desired shape.

quartz lamp plays a key role in the preform heating process in the oven.

blow machine is used to inflate the already softened base of a plastic bottle (preform) and form its final appearance. The composition of such equipment must necessarily include a compressor. This plastic bottle making machine should be equipped with a special neck overheat protection to keep the exact thread for screwing on the cap.

double mold is able to create a product from plastic of absolutely any appearance. Most often, for the production of containers from polymeric materials, high-pressure casting technology is used.

Plastic packaging created in this way is almost weightless and completely transparent, which is ideal for storing and selling all kinds of liquids. In addition, this container can be made in many color solutions and also have different shapes.

Also, the process of making plastic bottles does not require huge cash costs or large area to implement production. In other words, the production of plastic bottles is a process whose positive aspects can be listed for a very long time.

Plastic bottle production technology

As mentioned above, the process of manufacturing plastic containers is quite easy to implement. This is the reason why the production of PET bottles is so popular in factories producing beer or soft drinks. And this is not surprising, because positive sides there is just a lot of such production:

• First of all, this activity is completely inexpensive;
• Companies, engaged in the independent production of containers for their products, can reduce the cost of their goods;
• The appearance of plastic bottles can be made very original and unlike others.
• The container release process is fully automated;
• Due to the fact that it is quite difficult to break plastic bottles, there is no need to use special boxes for them, which also makes it possible to save money on transportation and sale.

The very same process of manufacturing plastic bottles occurs with the help of molding internal inflation. This method has evolved over time, and today it is simply ideal for every manufacturer.

Production steps for plastic bottles

The production process of PET bottles takes place in several stages. First, on an injection molding machine, a blank is made from the feedstock (from polyethylene terephthalate granules), which is called a preform. It is a small blank with an already formed threaded neck.

Next, the workpiece heated to a certain temperature is placed in a prepared mold and a special steel rod is placed in it. Under high pressure, air enters the workpiece, evenly distributed along the walls of the future container, creating a certain shape.

In carrying out this stage, it is extremely important to achieve the same air pressure at all points on the surface. It is possible to achieve the most effective result in the case of minimal time spent on the process. Only in this way can the possible deformation of an already finished plastic bottle be avoided.

After shaping, cool the finished product with air or liquid carbon dioxide. The concave bottom of the bottle and its convex inner part make such a container stable on a flat surface.

The final step in the production of plastic bottles is to remove any possible defects that may have been exposed as a result of the flow of molten plastic. After that, the finished products are sent for sorting using a moving container.

It is important to note that in the production of plastic containers, almost a quarter is discarded due to defects and recycled.

The role of secondary raw materials in the production of plastic containers?

Recycling secondary waste is a really serious topic, which concerns not only the environment, but also significant cost savings for the production of primary products. In the past few years, a breakthrough has been made in our country in the processing of secondary plastic waste.

Nowadays, plastic bottles are the most demanded secondary raw materials for the production of plastic polymers. And if until recently a huge number of plastic bottles were thrown away or burned, today the situation is on the mend.

To our great regret, so far the processing of containers has not reached perfection; every day it develops more and more. The only negative aspect is the lack of plastic waste recycling plants.

If you pay attention to the statistics, then the inhabitants of a small city with a population of around 100,000 inhabitants throw away more than 20 tons of plastic bottles every month. In addition, the amount of waste is increasing by about 1/5 every year. And if the recycling of such raw materials would be impossible, the country would be in for a real environmental disaster.

Speaking of more developed countries, then for them recycling is a valuable and profitable process. In Shanghai, for example, the recycling of secondary raw materials is so developed that, without having time to throw plastic containers into the trash, they will immediately pick them up for recycling. In our country, in turn, the lack of necessary factories is main reason a large number of PET bottles in landfills.

Modern technologies make it possible to obtain excellent raw materials from plastic waste for the production of almost any container. This principle has found wide application in many countries, creating a waste-free production cycle.

Machinery for making plastic bottles

It is used for the production of plastic containers by drawing and two-stage blowing. With this machine it is possible to produce bottles with a capacity of 0.25 to 2.2 liters with a capacity of about 3,000 bottles per hour. The products have found their application for the storage of carbonated and still liquids. This equipment consists of the following parts: preform loader, heater, manipulator and power plant.

Semi-automatic equipment of the MV series makes it possible to produce containers up to five liters. Such devices consist of a heater and a pneumatic shaper. The device is used for the production of plastic containers by heating with subsequent blowing. It consists of a power plant and a heater.

Such a powerful machine as isobaric filling triblock DXG 18-18-6 is designed for filling a wide range of liquids. The wide functionality and high performance of this device practically negates the need for maintenance personnel.

Plastic container for drinks in recent times is in great demand. You can pour juices, mineral waters, carbonated drinks, beer, and other alcoholic and non-alcoholic drinks into it. Therefore, organizing a business for the manufacture of plastic bottles is considered quite profitable. This will require an automated line for the production of bottles, a workshop where it will be located, service personnel. For businessmen who are engaged in the production of various drinks, it makes sense to purchase equipment for the manufacture of containers and independently carry out this process. Thanks to this, you can save up to 25% of the cost of plastic containers.

Features of PET bottles

Plastic bottles began to be produced in the 70s of the last century; DuPont was the first to produce this type of container. At that time, it became a revolutionary invention, and the bottles themselves seriously competed with glass bottles. To date glass bottles are rapidly being replaced by plastic ones due to a number of reasons:

But plastic has its drawbacks:

• it passes ultraviolet and oxygen, as a result of which the contents lose their characteristics and the shelf life is reduced;
• it releases carbon dioxide, which is especially true for carbonated drinks, kvass and beer.

Required raw materials for production

Polyethyl

The main raw material is polyethylene terephthalate - PET, thermoplastic. Plastic molecules polymerize under the influence of high temperature - they combine and form larger compounds, this is how the volume of raw materials increases. Dyes are used to give the product the desired shade. During the production process, some of the products are rejected, in this case there will be a high percentage of rejects - up to 25%, it can be processed using it as a raw material. Thus, waste-free production is obtained.

room

Workshop for the production of plastic containers To accommodate a line for the production of PET bottles, a room with an area of ​​​​more than 40 m 2, a ceiling height of 4 m will be required, while preparing it, fire safety requirements must be observed, since furnaces are used, the temperature of which during operation rises to 200 ° C. Therefore, it is desirable to veneer the walls and floor with tiles or non-combustible materials, concrete. The workshop must have three-phase sockets with a voltage of 380V. All utilities are required - plumbing and sanitation, air conditioning, ventilation. You will need separate storage facilities for storing raw materials and finished products. To organize a small enterprise focused only on the manufacture of plastic containers, it is not at all necessary to purchase real estate, it will be much more economical to rent production areas.

Production equipment

There are two types of plastic bottle production lines:

• single-phase, when the process of preform manufacturing and container blowing takes place in one place, while the preform will maintain a high temperature;
• two-phase, when the preforms are made on one machine, and then the line operator manually transfers and loads them into the blow molding machine. At the same time, the preforms cool down, and the blowing machine needs to heat them up again.

Components of an automated line:

• PET platform;
• bake;
• bottle blowing machine.

The PET platform is designed for preform formation by heat treatment of polyethylene terephthalate granules. Characteristics:

• number of nests - 6;
• mold thickness - up to 240 mm;
• power supply - 380 V;
• power - 73 kW;
• dimensions - 2000 * 950 * 2480 mm;
• weight - 250 kg.

Conveyor-type oven, as part of the PET bottle production line, is designed for heating preforms. Eight active zones provide uniform heating, so that in the future the product will be blown in the correct shape and the scrap rate will be reduced. Specifications:

• productivity - up to 1200 pieces / h;
• power - 8 kW;
• voltage - 380 V;
• dimensions - 1270 * 520 * 1220 mm;
• weight - 260 kg.

There are two types of blow molding machines:

• for the manufacture of containers with a volume of 0.2 to 5 liters;
• for the manufacture of containers with a volume of 5 to 19 liters.

Thanks to the high speed of hot air blowing, the blowing process is very fast and the bottle is well shaped. Characteristics:

• power - 5.5 kW;
• productivity - 700 pcs / h;
• blowing pressure - 14 atm;
• dimensions - 1800 * 500 * 1000 mm;
• weight - 250 kg.

The cost of the line for the production of bottles of this configuration will be 800 thousand rubles.

Manufacturing technology

Two-phase blowing line

At the first stage of the production cycle, it is necessary to form preforms - blanks. First, the feedstock is heated - polyethylene terephthalate, it comes in the form of granules, which, under the influence of high temperature, increase in volume and combine into a homogeneous mass. Then the hot mass is poured into metal molds, which can be standard, the most common, or can be made according to an individual project, then the finished product will have an original design. The filling process should be carried out as quickly as possible so that the molten mass is evenly distributed over the mold. If this step is performed correctly, the finished product will not be deformed.

In the next step, the preforms are cooled with liquid carbon dioxide, or water cooling is also possible. Further, the blanks are sent to the blow molding machine, where the process of bottle formation is carried out under high pressure, up to 30 atmospheres. Due to the high pressure, a minimum of time is spent on the entire process, and the product is obtained in the desired shape and size.

The next step is quality control, all products with visible deformations are subject to withdrawal and further processing. The line for the production of bottles can be supplemented with an automatic shredder of recyclables, defective products. Thus, to make production waste-free and save on raw materials.

Business features

Organization of your own enterprise for the manufacture of PET containers will not require significant capital investments. To start, you will need no more than 1.5 million rubles.

Heated preform under pressure can take any shape

During the production process, the main cost item will be wage staff. It will take three workers, a loader, a driver, a manager, an accountant and a manager, it is possible to combine managerial positions into one. Another significant cost item will be utility bills - during production there is a large consumption of electricity, since all equipment has a sufficiently large capacity. There will also be significant water consumption to cool preforms and finished products.

Despite high competition, this type of business is considered highly profitable, the cost of a bottle production line can pay off already within six months of equipment operation, provided that there is a full sale of finished products. This can be achieved by concluding agreements with manufacturers of drinks, juices, draft beer.
