AI Technical Summary

Problems solved by technology

1. Because there is a coating and silicone oil on the paper bottom, it is difficult to deal with, so now the paper bottom accounts for 90% of the industry, and there are problems of environmental protection and difficult recycling.
2. The base of PET film occupies 10% of the market, but the PET film itself is non-degradable and the mounting film contains a lot of silicone oil, so it is not environmentally friendly) 3. The existing environmental protection film is made of PVC material, which is non-degradable and coated with oily acrylic glue The toxic smell is very pungent and not environmentally friendly

Embodiment 1

[0015] (1) PEVA EVA VA is cast and formed by high-precision textured rollers, and then rolled up to about 4,500 meters after corona 38. ) after curing and finalizing, install it in a coating and gluing machine for gluing. (Vinyl acetate (VA) content is 5% to 40%. Compared with polyethylene, PEVA EVAVA introduces vinyl acetate monomer into the molecular chain, thereby reducing high crystallinity and improving flexibility, impact resistance, Filler compatibility and heat sealing properties are widely used in foamed shoe materials, functional shed films, packaging films, hot melt adhesives, advertising films, printing films, spray printing films, and toy films.

Abstract

The invention discloses a bottomless environment-friendly film and a manufacturing method and application thereof. Compared with polyethylene, the bottomless environment-friendly film of the inventionhas the following advantages: vinyl acetate monomer is introduced into the molecular chains of PE, PEVA, EVA and VA, so high crystallinity is reduced, the flexibility, the impact resistance, the filler intermiscibility and the heat sealing performance of the film are improved, and the film is degradable within three years, has high flatness and soft structure, belongs to food-grade standard filmsand can be widely applied to the fields of foaming shoe materials, functional shed films, packaging films, hot melt adhesives, advertisement films, printed films, jet-printed films, toy films, toys and the like.

Description

technical field [0001] The invention relates to the field of materials, in particular to a bottomless environmental protection film and its production method and application. Background technique [0002] At present, the print advertising material market is all environmentally friendly films with bottoms. The common environmental protection films have paper bottoms and PET bottoms. In terms of structure, they are all PVC films and oily acrylic glues, which are seriously unenvironmental. 1. Because there is a coating and silicone oil on the paper bottom, it is difficult to deal with, so now the market where paper bottoms account for 90% of the industry is not environmentally friendly and difficult to recycle. 2. The base of PET film occupies 10% of the market, but the PET film itself is non-degradable and the mounting film contains a lot of silicone oil, so it is not environmentally friendly) 3. The existing environmental protection film is made of PVC material, which is non-...
