Taw qhia rau kev tsim cov ntawv polyethylene nyob rau hauv daim ntawv thov teb ntawm blister tshuab

Polyethylene (PE) yog cov thermoplastic cob tau los ntawm polymerizing ethylene. Hauv kev lag luam, copolymers ntawm ethylene nrog me me ntawm alpha-olefins kuj suav nrog. Polyethylene tsis muaj ntxhiab tsw, tsis muaj tshuaj lom, zoo li siv quav ciab, muaj qhov kub thiab txias tsis kam (tsawg kawg ua haujlwm kub tuaj yeem ncav cuag -100 ~ -70 degree), tshuaj lom neeg ruaj khov, thiab tuaj yeem tiv taus feem ntau cov kua qaub thiab alkali yaig ( tsis resistant rau oxidation xwm acid). Nws yog insoluble nyob rau hauv ntau cov kuab tshuaj nyob rau hauv lub chav tsev kub, nrog tsawg dej nqus thiab zoo heev hluav taws xob rwb thaiv tsev. Thaum Lub Kaum Hli 27, 2017, cov npe ntawm cov carcinogens luam tawm los ntawm World Health Organization's International Agency for Research on Cancer tau raug txheeb xyuas ua ntej, thiab polyethylene tau suav nrog hauv cov npe ntawm 3 hom carcinogens.
