Tus txheej txheem ua hauj lwm ntawm polyethylene ntawv feem ntau yog raws li nws lub cev thiab tshuaj lom neeg.
Polyethylene ntawv yog cov khoom siv polymer ua los ntawm ethylene monomers, uas muaj cov khoom siv lub cev thiab tshuaj lom neeg zoo. Nws cov molecular saw qauv txiav txim siab nws qhov yoog raws thiab tshuaj lom neeg ruaj khov. Raws li qhov ntom ntom thiab molecular charcultement, polyethylene ntawv yog tsuas yog muab faib ua cov ntawv HDPE (qib siab polyethylene) thiab UHMWPE Sheet (ultra-siab molecular hnyav polyethylene). HDPE ntawv muaj siab tawv, hnav tsis kam thiab kub tiv taus (txog 100 degree), uas haum rau cov cuab yeej lag luam thiab cov thawv tshuaj; LDPE ntawv yog mos thiab cuam tshuam-resistant, thiab feem ntau siv rau cov ntaub ntawv ntim thiab cov khoom siv Cushioning; UHMWPE daim ntawv yog lub npe hu ua "King ofScastics", thiab nws cov chaw tiv thaiv yog 7 zaug ntawm cov teb kawg xws li cov neeg kho tshuab thiab cov ntawv cog tseg.
