Njirimara arụmọrụ nke ihe nkiri plastik bụ isi:
Ihe nkiri Polypropylene dabere na Biaxial (BOPP)
Polypropylene bụ resin thermoplastic mepụtara site na polymerization nke propylene. Copolymer PP ihe nwere obere okpomọkụ mgbagha okpomọkụ (100 ° C), obere nghọta, obere gloss, na ala siri ike, ma nwere ike mmetụta ike, na mmetụta ike nke PP na-abawanye na-abawanye nke ethylene ọdịnaya. Okpomọkụ Vicat dị nro nke PP bụ 150 Celsius. N'ihi ogo dị elu nke crystallinity, ihe a nwere ezigbo nkwụsi ike elu na ihe mgbochi ọkọ. PP enweghị nsogbu mgbawa gburugburu ebe obibi.
Ihe nkiri polypropylene biaxial (BOPP) bụ ihe nkwakọ ngwaahịa na-agbanwe agbanwe nke emepụtara na 1960. Ọ na-eji ahịrị mmepụta pụrụ iche na-agwakọta ihe ọkụkụ polypropylene na ihe mgbakwunye na-arụ ọrụ, gbazee ma gwakọta ya na mpempe akwụkwọ, wee gbatịa ha na fim.
