Plastic film new varieties have new applications

In the recently held 2004 China Plastics Forum Plastic Film New Technology Symposium, it was learned that plastic film is one of the rapidly developing plastics in recent years. Both the packaging film and the agricultural film are developing toward multi-functional and high-performance. At the same time, new varieties and new uses of film products have also been continuously developed.

For practical purposes, the packaging film is more emphasis on high performance and multi-functional, high permeability, selective permeability, heat resistance, antibacterial, rust, deodorant, shape memory and other market applications Development is very active.

Agricultural film is one of the main varieties of plastic film. At present, the main types of plastic film are drip mulching film, thin grass, thin degraded land, thin light-turning ground and thin spot/color matching. The study of functional films is based on the research and development of high weather resistance, high light transmittance, high heat preservation, long-term drop-mist anti-fog and improved light quality polyolefin multifunctional film.

The seminar also introduced several new types of film. Wrapping film has good application prospects in pasture silage and modern logistics for its excellent transparency, longitudinal extension, resilience, self-adhesion lap bonding, etc.; water-soluble film is used for packaging of food, medicine, chemical products, etc. To solve the environmental pollution caused by waste packaging materials.
