Three-tier co-extrusion blown film equipment in domestic development

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.

Three-tier co-extrusion blown film machineIs melted and blow into a plastic particles heating film machinery.Film blowing machine production is membrane are suitable for all kinds of top grade film packaging.This film because of its good barrier property, keeping fresh, well protected against dampness, frost proof, oxygen insulation, oil resistant, can be widely used in light and heavy package.Such as all kinds of fresh fruit, meat, pickles, fresh milk, liquid beverage, medical supplies, etc.


There are two kinds of plastic film on industrial (thickness at 0.005 mm to 0.005 mm.) production method --, rolling and extrusion method, which method is divided into extrusion blown film extrusion machine, extrusion drawing and extrusion flow.Currently the most widely used production process of the extrusion blown film, extrusion drawing and extrusion flow delay, especially polyolefin film, and some rolling method is mainly used for production of polyvinyl chloride (PVC) film.In extrusion blown film, extrusion drawing and extrusion flow YanZhong, because of the extrusion blown film equipment overall manufacturing technology constantly improve and relative to the stretch and stretch film equipment relatively much lower cost, and application in growing.


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.


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.
