I-LGLPAK ibigxile emikhiqizweni yepulasitiki, futhi ukugoqa kwepulasitiki kuwumkhiqizo ojwayelekile.
Ifilimu yokunamathela iwuhlobo lomkhiqizo wokupakisha wepulasitiki, ovame ukwenziwa ukusabela kwe-polymerization nge-ethylene njengeqoqo elikhulu.
Ifilimu yokudla ingahlukaniswa ngezigaba ezintathu:
eyokuqala i-polyethylene, ebizwa ngokuthi i-PE;
eyesibili i-polyvinyl chloride, ebizwa ngokuthi i-PVC;
Eyesithathu i-polyvinylidene chloride, noma i-PVDC ngamafuphi.
Ukushisisa ukudla kwe-microwave, ukugcinwa kokudla kwesiqandisi, ukupakishwa kokudla okusha nokuphekiwe nezinye izikhathi, emkhakheni wempilo yomndeni, izitolo ezinkulu, amahhotela nezindawo zokudlela, kanye nokupakishwa kokudla kwasembonini, iningi lokugoqa kwepulasitiki nezikhwama zepulasitiki ezisetshenziswa kakhulu ezithengiswa emakethe. zenziwe nge-Ethylene masterbatch iyimpahla eluhlaza.
Ngokwezinhlobo ezahlukene ze-ethylene masterbatch, ifilimu yokudla ingahlukaniswa izigaba ezintathu.
Eyokuqala i-polyethylene, noma i-PE ngamafuphi.Le nto isetshenziselwa kakhulu ukupakisha ukudla.Ifilimu esivame ukuyithengela izithelo nemifino, okuhlanganisa nemikhiqizo ethengwe esitolo esikhulu, konke kusetshenziselwa lokhu kwaziswa;
Uhlobo lwesibili yi-polyvinyl chloride, noma i-PVC ngamafuphi.Le nto ingasetshenziselwa futhi ukupakisha ukudla, kodwa inomthelela othile ekuphepheni komzimba womuntu;
Uhlobo lwesithathu yi-polyvinylidene chloride, noma i-PVDC ngamafuphi, esetshenziselwa ikakhulukazi ukupakisha ukudla okuphekiwe, i-ham neminye imikhiqizo.
Phakathi kwezinhlobo ezintathu zokugoqa kwepulasitiki, ukugoqa kwepulasitiki kwe-PE ne-PVDC kuphephile emzimbeni womuntu futhi kungasetshenziswa ngokuzethemba, kuyilapho ukugoqa kwe-PVC kuqukethe izinto ezibangela umdlavuza futhi kuyingozi kakhulu emzimbeni womuntu.Ngakho-ke, lapho uthenga ukugoqa kwepulasitiki, Okungeyona ubuthi kufanele kusetshenziswe.
Ngokombono wenyama, ifilimu yokudla inokungeneka okusesilinganisweni komoyampilo kanye nokungena komswakama, ilungisa umoya-mpilo kanye nomswakama ozungeze umkhiqizo ogcina umusha, ivimba uthuli, futhi yandisa isikhathi sokugcina ukudla okusha.Ngakho-ke, kuyadingeka ukukhetha ukugoqa kwepulasitiki okuhlukile kokudla okuhlukile.
Ngemva kokuqonda, wonke umuntu kufanele anake ukukhetha lapho ekhetha ifilimu yokudla ekuphileni kwansuku zonke ukuze agweme izinto ezinobuthi.
