Do que é feito o polietileno? Produção de polietileno. Produtos de polietileno

Processo tecnológico

O processo tecnológico de fabricação de sacolas de polietileno consiste nas seguintes transições:

· produção de filme tubular de polietileno. Ambos de alta pressão (PEBD) e polietileno de baixa pressão (PEBD) são usados ​​como matéria-prima. Se o produto final for uma sacola de camiseta, então, nesta fase, a capa do filme é dobrada. Se for necessário aplicar um design ao produto, a manga é pré-coronizada;

· impressão(se necessário). O desenho é aplicado na bolsa por meio de flexografia;

· cortar uma capa de filme enquanto simultaneamente forma o fundo do saco.Sacolas tipo “camiseta” requerem mais uma operação – a formação de duas costuras soldadas no lado da “alça”. A manga com o padrão impresso é cortada por meio de uma fotocélula especial que determina a localização da impressão;

· cortando a garganta do pacote(a operação é realizada na produção de “camisetas” ou bolsas com alças recortadas).

Máquinas para produção de sacolas plásticas

Como a produção de sacolas plásticas é um processo contínuo, é aconselhável utilizar linhas automáticas para sua produção. Eles estão equipados com os seguintes módulos:

· extrusora: serve para processar matérias-primas de polietileno fornecidas na forma de grânulos e formar uma manga ou filme tipo aberto;

· máquina de corte e solda: projetado para cortar filmes ou mangas em pedaços de um determinado comprimento. A mesma máquina sela a peça de trabalho de um lado, forming the actual package. Having only an extruder and a cutting-soldering machine, you can produce bags without handles (including plastic bags for garbage);

· punching press: included in lines for the production of “T-shirt” bags or with cut-out handles;

· flexographic machine: Designed for applying various company logos or designs to the surface of the package. The production of plastic bags for T-shirts with a logo is only possible if this device is included in the equipment set.

Equipment Manufacturers

The main suppliers of equipment for the production of plastic bags to the Russian market are Taiwan, Türkiye and China.

Gur-is makina

The Turkish company was founded in 1988. It is a family business that, thanks to the active implementation of advanced technologies, has been able to achieve great success in the production of high-quality equipment.

Hyplas is one of the leaders in Taiwan in the production of equipment for the production of bags, bags, LDPE and HDPE bags, rotogravure and flexographic machines. The products of this manufacturer have high performance. Moreover, its cost is very affordable. The ease of installation and commissioning process makes Hyplas equipment particularly attractive.

Mingde Machinery Company

The Chinese manufacturer of equipment for the production of polymer products is well known in the domestic and international markets. The company’s product list includes a large number of modifications of extruders for the production of polyethylene film, machines for the production of OPP bags, T-shirt bags and with a loop handle. The company also produces extruders with a pattern application device. You can also purchase equipment for recycling and subsequent granulation of polyethylene waste from them. The company’s specialists practice designing equipment to order.

Domestic producers

Russian factories are very successfully mastering the production of equipment for plastic bags. For example, the Aleko group of companies has occupied a worthy place in the market for at least 20 years. The structure of the group includes the APO Aleko-Polymers complex and the Aleko Extrusion Technology plant, which specializes in the manufacture of polymer equipment. Currently, the group is one of the country’s leading developers and manufacturers of equipment for processing polyethylene waste, producing plastic bags, and flexographic equipment.

Equipment for the production of plastic bags: estimated price

In Russia, the cost of a set of equipment for the production of plastic bags starts from 400 thousand rubles. The price is influenced by the technical parameters of the machines, the completeness of the line and the manufacturer. The most expensive element in the set is the flexographic machine: its average cost is approximately a million rubles.

The most expensive are automatic lines equipped with machines for applying patterns and processing polyethylene waste. But entrepreneurs who want to open a plant for the production of plastic bags can start with a minimum set and then expand it.
