Izinto zokupakisha ezihlanganisiwe

Ngokusekelwe ekuthuthukisweni kwemboni yokupakisha, ukupakisha izimpahla kuye kwaba

futhi kuthuthukiswe ngokufanele. Kusukela ekupakisheni okulula kwephepha, kuya kusendlalelo esisodwa sokupakisha ifilimu yepulasitiki, kuthuthukiswe kuya ekusetshenzisweni kabanzi kwezinto ezihlanganisiwe. Ifilimu ehlanganisiwe ingenza okuqukethwe kokupakisha kube nezici zokuthambisa, iphunga elimnandi, ubuhle, ukulondolozwa, ukukhanya, ukugwema, ukungena, ukwandisa isikhathi sokuphila kweshelufu kanye nezinye izici, ukuze sithole intuthuko esheshayo.

Izinto ezihlanganisiwe ziyizinto ezimbili noma ngaphezulu, ngenqubo eyodwa noma ngaphezulu ezihlanganisiwe futhi zihlanganiswe ndawonye, ​​ukuze zakhe umsebenzi othile wezinto ezihlanganisiwe. Ngokuvamile zingahlukaniswa zibe ungqimba lwesisekelo, ungqimba olusebenzayo kanye nongqimba lokuvala ukushisa. Izinga lesisekelo lidlala indima enhle, yokunyathelisa, yokumelana nomswakama kanye nenye indima. Njenge-BOPP, i-BOPET, i-BOPA, i-MT, i-KOP, i-KPET, njll., ungqimba olusebenzayo luvimba futhi lugweme imisebenzi yokukhanya, njenge-VMPET, i-AL, i-EVOH, i-PVDC; ungqimba lokuvala ukushisa luthintana ngqo nezinto zokupakisha, ukuzivumelanisa nezimo, ukumelana nokuvuleka, ukuvalwa okuhle kokushisa, njenge-LDPE, i-LLDPE, i-MLLDPE, i-CPP, i-VMCPP, i-EVA, i-EAA, i-E-MAA, i-EMA, i-EBA, njll.
