The three-layer coextruder film machine plays an important role in the plastic industry

The three - layer co-extrusion film machine in dalian occupies an important industry status in the plastic industry. At present, the existing domestic film blowing machine manufacturers are mostly unsuited to the market demand and the need to improve the technology to produce the market film blowing machine. Diffusion and application of flat and tapered stack. Improve the screw to meet the performance of a new plastic raw material, improve the capacity of plasticization, increase production, reduce energy consumption and save energy.

Five or more layers of more than five layers of multi-layer coextruder. Heavy packing thin film blowing multi-layer coextruder production. Production of environmentally friendly film blowing machines (such as water soluble film, starch film, photodegradation film, biodegradable film etc.). High performance film blowing machine can be produced. (such as high performance barrier films, high performance nylon films, high-performance medical films and high performance composite films). Thus to improve the product quality, enhances the technical transformation of film blowing machine, improve the performance of the equipment, is a pressing task, is also a blow molding machine manufacturers in China, also is our survival and the development path.

For more than 20 years of reform and opening-up, the rapid development of plastic packaging industry of China is steady, has been from the early stages of a dispersion become independent the development of the industry, product category is complete modern industrial system. According to the forecast, to 2005 years in the field of plastic packaging materials in China market demand will reach 5.5 million tons, with an average annual growth rate of 1 o % demand, the fastest growing in the plastic products industry, is has a broad prospects for development of sunrise industry. Among them, the film is the largest amount of plastic packaging materials, because of its non-toxic, light weight, beautiful packaging, the characteristics of low cost, and thus develop applications, almost penetrated into all aspects of the agricultural and industrial products and daily necessities, plastic packaging film industry investment is growing rapidly.

Along with our country joining the WTO and economic globalization, the fierce competition in the market and the improvement of people's living standard, people to the pursuit of spiritual and material civilization, pay attention to inner quality has been the trend of The Times, many people begin to accept the developed countries pay attention to the packaging concept, function, light appearance for pollution-free health packaging and decoration, the multi-layer co-extrusion plastic film and blow molding equipment is undoubtedly a good opportunity of development.

At present, the plastic film monolayer film blowing equipment many for early buy old equipment, widespread technology backwardness, serious equipment aging, the poor adaptability of raw material, large energy consumption, low production, film quality is bad, must be updated. Nearly 5-6 years domestic plastics factory purchase a certain number of 2 ~ 3 layers co-extrusion film blowing equipment, but far short of the needs of the development of current multi-layer co-extrusion plastic film production, cannot satisfy the high barrier function such as a plastic film extrusion molding production, thus unable to effectively replace solvent volatilization packaged food residual harmful substances, environmental pollution, pollution, affect human body health of dry type composite technology.
