I-LGLPAK igxile kwiimveliso zeplastiki, kwaye ukusonga iplastiki yimveliso eqhelekileyo.
Ifilimu yokubambelela luhlobo lwemveliso yokupakisha yeplastiki, edla ngokwenziwa ngokusabela kwepolymerization nge-ethylene njengebhetshi enkulu.
Ifilimu yokutya inokwahlulwa ibe ngamacandelo amathathu:
eyokuqala yi-polyethylene, ekubhekiselwa kuyo njenge-PE;
okwesibini yi-polyvinyl chloride, ebizwa ngokuba yiPVC;
Okwesithathu yi-polyvinylidene chloride, okanye i-PVDC emfutshane.
Ukufudumeza ukutya kwe-microwave, ukugcinwa kokutya kwefriji, ukupakishwa kokutya okutsha kunye okuphekiweyo kunye nezinye izihlandlo, kummandla wobomi bosapho, iivenkile ezinkulu, iihotele kunye neeresityu, kunye nopakisho lokutya kwimizi-mveliso, uninzi lokusonga kweplastiki kunye neengxowa zeplastiki ezisetyenziswa ngokuqhelekileyo ezithengiswa kwimarike. zenziwe nge-Ethylene masterbatch yimathiriyeli ekrwada.
Ngokweentlobo ezahlukeneyo ze-ethylene masterbatch, ifilimu yokutya inokwahlulwa ibe ngamacandelo amathathu.
Eyokuqala i-polyethylene, okanye i-PE emfutshane.Esi sixhobo sisetyenziselwa ikakhulu ukupakisha ukutya.Ifilimu esihlala siyithengela iziqhamo kunye nemifuno, kubandakanywa neemveliso ezigqityiweyo ezithengwa kwivenkile enkulu, zonke zisetyenziselwa le nto;
Uhlobo lwesibini luyi-polyvinyl chloride, okanye i-PVC emfutshane.Esi sixhobo sinokusetyenziselwa ukupakishwa kokutya, kodwa kunempembelelo ethile kukhuseleko lomzimba womntu;
Uhlobo lwesithathu yi-polyvinylidene chloride, okanye i-PVDC emfutshane, esetyenziselwa ukupakishwa kokutya okuphekiweyo, i-ham kunye nezinye iimveliso.
Phakathi kweentlobo ezintathu zokusonga iplastiki, i-PE kunye ne-PVDC yokusonga iplastiki ikhuselekile kumzimba womntu kwaye ingasetyenziswa ngokuzithemba, ngelixa ukusonga kwe-PVC kuqulethe i-carcinogens kwaye iyingozi ngakumbi kumzimba womntu.Ke ngoko, xa kuthengwa iplastiki yokugoqa, i-Non-toxic kufuneka isetyenziswe.
Ukusuka kumbono womzimba, ifilimu ye-cling inomlinganiselo ophakathi kwe-oksijini kunye nomswakama, ilungelelanisa i-oksijini kunye nomswakama ojikelezayo kwimveliso yokugcina entsha, ivimbela uthuli, kwaye yandisa ixesha lokugcina ukutya.Ngoko ke, kuyimfuneko ukukhetha iiplasitiki ezahlukeneyo zokutya ezahlukeneyo.
Emva kokuqonda, wonke umntu kufuneka ahlawule ingqalelo ekukhetheni xa ukhetha ifilimu yokutya kwimihla ngemihla ukuphepha izinto ezinobuthi.
