Equipment for the production of polypropylene sleeves. Selection of technological equipment for the production of polypropylene bags. Search for a suitable premises for organizing a production workshop

There are eternal things that are present in the life of an average citizen of the post-Soviet space. One of them is a full trash can.

And if you figure it out, it's not so bad - you must admit, since there is something to throw away, it means that there is something to buy for something that you will throw away anyway. We will talk about this household need in the article. To be more precise, let's consider a business idea for the production of polypropylene garbage bags, and more.

This product is used in many areas, as an example, the construction or agro-food industries. Depending on the material used, cereals, sugar, flour, animal feed, sand, cement, building mixtures, etc. are stored and transported in polypropylene bags. From which we can conclude that there will be a good demand for this product.

Raw materials used

Polypropylene is used as the main raw material. It is supplied to production in the form of granules. In addition, secondary raw materials can also be used, for example, scrap or waste generated during work. As a rule, non-standard is added to the mixture in a percentage ratio determined by the technology. In addition to polypropylene, additional components are introduced into the raw mix during the production process, which give the finished product the necessary color and strength.

Manufacturing technology

The technology for the production of polypropylene bags is not particularly complex. The following main stages can be distinguished: mixing and drying of raw materials, winding the thread, making the fabric, cutting, applying the logo, tailoring, packaging and warehousing.

If you can purchase high-quality automated equipment for the production of polypropylene bags, then the minimum amount of manual labor will be involved in the technological process, which will ultimately affect the payback of this business.

Production and processing of polypropylene yarn

As mentioned above, raw materials are supplied in granules. After that, it is loaded into equipment for the production of polypropylene bags and mixed with various additives and dyes in a special hopper. One of the main auxiliary components is calcium carbonate, it is designed to give the finished product the necessary rigidity and milky white color.

Any additives are designed to set the properties of the future material. Some manufacturers add 15-20 percent of chalk to the mixture to reduce the cost of production, but this negatively affects the strength of the bags.

After the hopper, the raw material enters the extruder, where it is heated to 260 degrees Celsius and squeezed out through the technological channels of the press head, resulting in a thin film. After cooling, it is cut into thread-strips, which are hardened, stretched and wound on bobbins.

Obtaining a polypropylene sleeve

Next, the coils are sent to a weaving machine for the production of polypropylene bags. This equipment produces a sleeve for future bags. At this stage, the loom is adjusted to the necessary parameters, namely, its width and the presence of anti-slip threads are set.

This is done so that during operation the bags stacked on top of each other do not move apart during transportation and storage. The resulting polypropylene woven material is wound onto large spools.

Getting a polypropylene bag

Next, the material must be cut, stitch the bottom and process the neck. This is carried out by a special line for the production of polypropylene bags, which, by hot cutting, quickly turns the prepared sleeve into blanks for future products. The cut line can be made both flat and zigzag.

Further equipment for the production of polypropylene bags tucks right amount once the bottom and stitch it with a strong thread. The manufacturing algorithm may include the processing of the neck (edging, stitching, etc.), or may leave it unprocessed. Sometimes polyethylene liners are added to such bags and sewn on. Finished products automatically stacked in packs of 500 or 1000 pieces and packed, pressed and tied with twine.

Technical equipment of the workshop

If you decide to organize the production of polypropylene woven bags, you should take into account the costs of purchasing the necessary industrial plants. The modern technological market in Russia is represented by a large selection of devices and machines, both domestic and foreign.

Among this abundance, every businessman will be able to choose a unit that is suitable in terms of power and price. Standard equipment for the production of polypropylene bags includes a device for mixing and drying components, a feeding machine, a thread extruder, a winding complex, a weaving machine, a sleeve cutting unit, sewing machine for stitching, flexo printing device for applying a logo.

In order to be able to process scrap and waste during the manufacturing process, the following installations should be additionally purchased: a crusher designed to grind material (substandard, threads); a granulator that turns the crushed raw materials back into polypropylene granules, which can be reused for production.

For savings starting investments experts recommend purchasing equipment from China. Today, Asian installations are of good quality and low price. In addition, you can consider the option of acquiring machine tools in leasing, which is a kind of rental. Over time, you will have the opportunity to redeem this equipment.

Premises for the future workshop

When organizing production, you should take into account the fact that you will work with polymer raw materials, which means that the workshop must be located away from residential areas. Few start-up entrepreneurs can afford to purchase industrial premises for personal ownership. The best option would be to rent a workshop somewhere outside the city. In order to open an enterprise for the production of polypropylene bags, the premises must meet the following requirements:

1. Supply of all communications (sewerage, water, heat and electricity).

2. The presence of air cleaning filters.

3. Good system ventilation.

The area of the production facility will depend on the configuration of the industrial line you have chosen. Often the equipment is located on a plot of 50 square meters. Of course, rooms for staff, a garage for vehicles, warehouses for raw materials and finished products should also be added.

Sale of polypropylene bags

If you are organizing production from scratch, then at the stage of developing a business plan, you should consider ways to sell products. The main buyers may be construction companies, private entrepreneurs, warehouse complexes, agricultural producers (small and large farms), and, of course, household supermarkets.

Production of polypropylene bags

Friends! In our article, we will talk about how polypropylene bags are made, describe the main stages and technological features, we will introduce you to the work in detail. You can also immediately familiarize yourself with the detailed video material on the production of polypropylene bags -.

The process of manufacturing polypropylene bags is carried out in several stages and is carried out within the same enterprise.

Preparation of polypropylene raw materials.
Finished product packaging.

Now let's take a closer look at each stage.

Production process of polypropylene bags

Preparation of polypropylene raw materials

Raw materials are supplied to the plant for the production of polypropylene bags in the form of granules, which, depending on the purpose, are of two types.

Primary raw materials (polypropylene) are used in the production of bags for food and bulk products due to the increased strength of the material. Such products must comply with sanitary and hygienic requirements.

Polypropylene is made from propene gas. Initially, the substance is obtained in the form of a powder, which is dried, mixed with additives and formed into granules with a diameter of two to five millimeters.

Secondary raw materials, which are made by processing waste products, polypropylene products, for example, old bags. Such raw materials are not used for food products.

Secondary raw materials are made using a grinder. The drum of the device is filled with secondary materials, where they are crushed to the desired size.

Fabric threads are made from polypropylene film by processing raw materials on a special machine - an extruder. But initially, the raw materials must be dried so that when heated in the extruder hopper, no vapor is formed. For this, an industrial furnace is used, where the original raw materials are immersed. Moisture removal is carried out at a temperature of 80 ° C.

When the initial raw material completely gets rid of moisture, they begin to manufacture polypropylene threads.

The production of threads, as already mentioned, is carried out from a polypropylene film. To obtain it, dry raw materials are poured into the receiving hopper of the extruder, where it is mixed with dyes and additives. At this stage, calcium carbonate is added ( Chemical substance, which is obtained by combining calcium and salt carbonic acid). This component not only gives the desired shade to the product, but also increases rigidity. The additives used directly affect the properties of the resulting material.

Then the mixture enters the heating tank, where it melts at a temperature of 260 ° C. The molten mixture is squeezed out through a special nozzle, resulting in a continuous film that cools under air pressure.

The finished film is cut into threads of a given thickness, which are wound on coils. At this stage of production, it is important to monitor the thickness of the thread and change the coils in a timely manner. If the thickness changes, the cutting blades need to be adjusted.

The finished coils are delivered to the weaving shop, where a polypropylene sleeve is directly produced - the main material for the production of polypropylene bags.

Finished spools with polypropylene thread are fed to a circular loom, where the sleeve is produced. Before the beginning technological process the specialist configures the necessary parameters of future products:

thread weaving density;
thread tension;
polypropylene sleeve width;
the presence of an anti-slip thread, which is used to prevent the bags from slipping, and its parameters.

After setting the characteristics by the shuttle method, a polypropylene sleeve is produced, which is wound on bobbins. Finished bobbins can be transported to the warehouse or directly fed to the next stage of production.

Babins have a large diameter and weight, so special equipment is used to transport them.

The polypropylene sleeve is printed flexographically using a special machine. This method is characterized by the use of flexible printing materials (dyes), which allows printing even on uneven surfaces. The layer of polypropylene sleeve enters through rollers that rotate the paint containers. As a result, the desired pattern is applied to the product. After that, the sleeve is again wound on bobbins and sent for cutting and sewing.

The cutting of the polypropylene sleeve is carried out on a special line, where the hot cutting method is used. The machine independently determines the side on which the pattern is applied using a photocell.

The hot cutting method involves melting the end threads of the bag so that they do not spread in the future.

After the blank for the bag is cut off from the polyethylene sleeve, the machine tucks the bottom of the product, usually once or twice, and sews the seam with a multifilament thread, which is also called polypropylene.

The peculiarity of this thread lies in the longitudinal division, in contrast to the monofilament.

trimming by direct hot cutting or zigzag;
one or two gates;
stitched once or twice;
without additional processing.

Finished products are packed in packs of 100, 200, 250, 300, 500 or 1000 pieces, depending on the size. After that, the bundles are pressed and packed in a film or wrapped in polypropylene fabric, after which they are again pressed and covered with twine. Finished bags are sent for storage or transported.

Additional steps for the manufacture of polypropylene bags

In the production of laminated bags, a polypropylene sleeve is first processed with a melt of polypropylene, polyethylene or a mixture of them on one or two sides, and only after that it enters the line for cutting and hemming.

The neck with a valve is made in two ways:

in ordinary (stitched) bags, the valve is formed manually;
in laminated box bags, the valve is formed automatically on the machine.

In the production of polypropylene bags with an insert, after the products are cut and the bottom is hemmed, the insert is manually sewn by seamstresses to the top of the bag. When using special equipment, it is possible to automate the process of sewing in an insert: it is fed along with a polypropylene sleeve and is hemmed on top of the product and along the bottom.

Polypropylene bags are durable, inexpensive, water-resistant packaging with the possibility of repeated use. Due to its low cost and wide possibilities, such polypropylene containers are in demand in many industries. Polypropylene bags can be completed with polyethylene inserts, handles (slings), valves. Such a construction is called. In Russia, there is competition in the market of polypropylene bags, in almost every region there are several manufacturers of polypropylene bags. In the article we will give a list of them by region of the Russian Federation for the convenience of choosing the right supplier.

Manufacturers of polypropylene bags, list

In Russia, the market for polypropylene containers is represented by manufacturers and intermediaries. The second category is represented by online stores and wholesale and retail warehouse companies that sell different kinds packaging.

When purchasing small batches of p / p bags, it is sometimes more convenient to turn to an intermediary, the difference in price will not be very noticeable. If you need a large amount of packaging, it is better to purchase directly from the manufacturer without intermediaries.

The production of polypropylene bags is a rather laborious process and includes several stages, which can be divided into separate production areas:

Filament Extrusion Line- obtaining strong elastic threads from polypropylene granules. The most important stage in the production of polypropylene packaging, it is at this stage that the main technical characteristics of the future bag are formed - strength, elasticity, weight, color. For the manufacture of polypropylene bags, only high-quality certified raw materials from chemical industry manufacturers are used.

weaving section– polypropylene threads are threaded into modern high-tech looms, where they are woven into a fabric (polypropylene sleeve). Polypropylene bag factory equipped with equipment from the Austrian company Starlinger - a leader in the production of weaving machines. In the manufacture of polypropylene fabric bag manufacturers an anti-slip thread is added (specially twisted pp threads) to reduce the "slipperiness" of the bag, which prevents the bags from slipping off the pallets (pallets) during loading / unloading.

pp bag cutting section– cutting of polypropylene fabric on cutting and stitching machines. The produced fabric (sleeve) with a width of 35, 40, 50, 55, 56, 80 cm is cut to a given length from 50 cm to 130 cm, followed by stitching.

Flexographic printing department- drawing a picture, text, logo on a polypropylene bag. The available equipment allows you to quickly and efficiently obtain beautiful polypropylene packaging with a logo at the request of the buyer.

In order for the produced polymer packaging to be suitable for contact with food, the manufacturer of polypropylene bags uses only water-based paints.

Polyethylene liner production site.

Polypropylene bags (production), depending on the purpose, can be supplemented with an insert. For packaging hygroscopic products such as granulated sugar, inside the polypropylene woven bag is added plastic bag(insert). Bag making with an insert made of low-pressure polyethylene has distinctive features from the production of standard polypropylene bags for flour, cereals, starch. The inner polyethylene bag is inserted into the outer polypropylene bag, straightened and stitched along the top, eliminating the possibility of their displacement relative to each other. On the market polymer products bag manufacturers offer, as an alternative to a bag with an insert, a polypropylene bag with lamination (the method of thin coating of a PP canvas with a film). By technical specifications, a laminated bag does not differ from a bag with an insert, and the price of packaging with a film application is significantly higher.

A sewing section and a section for packaging finished polypropylene products.

Today, bags-bags of 5 and 10 kg with handles and without handles are in great demand, based on the wishes of buyers of polypropylene packaging, a sewing factory, the creation of which allowed to expand the range of products. Today, the manufacturer produces polypropylene bags with handles for small packing, bags with a valve for chemical products, polypropylene bags with a hemmed top. How sack manufacturers we carry out orders for tailoring non-standard packaging of large sizes (large-sized).

Bag production woven, based on a full technological cycle, allows not only to produce high-quality and reduce the cost of the product, but most importantly, to develop the most profitable packaging solutions in accordance with the requirements of the buyer.

Currently bag production(pp bags) - quite popular, since polypropylene bags (bags) are a reliable and economical type of packaging. By performance characteristics polypropylene bags (manufactured by Suraplastic) have a number of advantages over jute and paper bags, such as high mechanical and impact strength, resistance to repeated bending and abrasion, have low vapor and gas permeability, and are environmentally friendly when working with food products.

Polypropylene bags from the manufacturer are used for packaging, transportation and storage of various food bulk products (sugar, salt, flour, cereals), as well as non-food chemical products (fertilizers, additives, reagents) and construction industries (sand, expanded clay, dry mixes) . The manufacturer produces polypropylene bags with a standard capacity of 5kg, 10kg, 25kg, 50kg, which are always in stock. Production of polypropylene bags larger volume is possible technical parameters, necessary for the client. It is important to remember that bag manufacturers guarantee the availability required documents– Quality Certificate and Sanitary and Epidemiological Conclusion required for admission when packing food products.

Modern high-tech equipment, high-quality raw materials, Hi-tech, quality control at every stage of production, the experience of qualified industry specialists - all this allows us to fully meet the needs of your company in polypropylene packaging. If you need pp bags from the manufacturer, pp fabric, bags with handles, logo bags, pp bags wholesale, in as soon as possible and by reasonable prices contact our specialists.

Polypropylene bags from the manufacturer "Suraplastic" - attention to you, a guarantee of the quality of packaging and timely execution of your order.

Polypropylene bags are often used for storage, transportation and packaging of food and non-food products. They have a fairly low cost and wide application. Polymer packaging is practical and greatly simplifies the sale of products. Such packaging is more often used for packaging bulk food products (sugar, salt, cereals), fertilizers, building materials. The maximum weight of the contents of the bag depends on the size and density of the bag and can reach several centners.

The production process of polypropylene bags consists of several stages:

1) cleaning and extrusion of the web film;
2) getting the canvas;
3) cutting bags;
4) drawing logos;
5) sewing bags and packaging.

For greater strength and to reduce slippage of bags in the hands, special additives are used that make the fabric rougher, and the threads for sewing products more durable.
