plastic stretch film in china

pallet stretch film

stretch film may be polyethylene, polyvinyl chloride, ethylene - vinyl acetate copolymer (EVA) and other production. PVC as a substrate initially, with the DOA plasticizer and

tackifier to produce PVC stretch film, PVC stretch film with a stretch because of poor performance, and in the tension state prone to stress relaxation, packaged goods, stretch

film is less stable, high cost and poor adaptability to environmental shortcomings, PVC stretch film it later, following the successful development of polyethylene stretch film,

and has been widely used, and now in addition to anti-PVC stretch film fog performance is better, plastic wrap in the refrigerator, there is still the application, the

application in other areas basically been eliminated. Polyethylene stretch film early EVA-tackifier, but its high cost and has a sour shortcomings, the current stretch film is

basically the production of polyisobutylene (PIB) or ultra low density polyethylene (VLDPE) as thickening agent, to linear low density polyethylene (LLDPE) as the main

substrate. Used to produce stretch film LLDPE, including butene, hexene, octene copolymer, producing automatic use stretch film LLDPE, and even use some of metallocene polyethylene

(mPE), in order to get a good physical and mechanical properties; in the production of manual use stretch film LLDPE, in order to reduce costs, but also containing butene LLDPE and

LDPE resin mixture; home stretch film (commonly known as the refrigerator plastic wrap) for stretch film's mechanical strength is low, the use of low-density polymer as the main

raw material for production of stretch film
