Izixhobo zokupakisha ezidityanisiweyo

Ngokusekelwe kuphuhliso lweshishini lokupakisha, ukupakishwa kweempahla kuye

nayo yenziwe ngokufanelekileyo. Ukususela ekupakisheni iphepha elilula, ukuya kumaleko omnye weplastiki yokupakisha ifilimu, yaphuhliswa ukuya ekusetyenzisweni ngokubanzi kwezinto ezidityanisiweyo. Ifilimu edityanisiweyo ingenza umxholo wokupakisha ube neempawu zokufumisa, ivumba elimnandi, ubuhle, ukugcinwa, ukukhanya, ukuphepha, ukungena, ukwandisa ubomi beshelufu kunye nezinye iimpawu, ukuze sifumane uphuhliso olukhawulezayo.

Izinto ezidityanisiweyo zizinto ezimbini okanye ngaphezulu, ngokusebenzisa inkqubo enye okanye ezingaphezulu ezidityanisiweyo kwaye zidityaniswe kunye, ukuze zenze umsebenzi othile wezinto ezidityanisiweyo. Ngokubanzi zingahlulwa zibe ngumaleko wesiseko, umaleko osebenzayo kunye nomaleko wokutywina ubushushu. Inqanaba lesiseko lidlala indima entle, yokuprinta, yokumelana nokufuma kunye nenye indima. Njenge-BOPP, i-BOPET, i-BOPA, i-MT, i-KOP, i-KPET, njl.njl., umaleko osebenzayo uvimba kwaye uphephe imisebenzi yokukhanya, efana ne-VMPET, i-AL, i-EVOH, i-PVDC; umaleko wokutywina ubushushu unonxibelelwano oluthe ngqo nezinto zokupakisha, ukuguquguquka, ukumelana nokuvuleka, ukutywina okuhle kobushushu, njenge-LDPE, i-LLDPE, i-MLLDPE, i-CPP, i-VMCPP, i-EVA, i-EAA, i-E-MAA, i-EMA, i-EBA, njl.njl.
