Isikhwama Esiphrintiwe Ngokwezifiso Se-Flat PE Plastic Poly Bag Sokupakisha Ukudla Okuqandisiwe

Kunezinhlobo eziningi zezinto zokupakisha ezinezakhiwo ezahlukene.Kuphela ngokuqonda izici ezibonakalayo zezinto ezihlukahlukene zokupakisha singakwazi ukukhetha izinto ezifanele ngokuvumelana nezidingo zokuvikela zokudla okuqandisiwe, ukuze zingagcini nje ngokugcina ukunambitheka nekhwalithi yokudla, kodwa futhi zibonise ukubaluleka komkhiqizo.

Njengamanje, ukupakishwa okuguquguqukayo kwepulasitiki okusetshenziswa emkhakheni wokudla okuqandisiwe kuhlukaniswe ikakhulukazi izigaba ezintathu:

Uhlobo lokuqala izikhwama zokupakisha ezinongqimba olulodwa, njengezikhwama ze-PE, ezinemiphumela emibi kakhulu yokuvimbela futhi ezivame ukusetshenziselwa ukupakisha imifino;

Isigaba sesibili yizikhwama zokupakisha zepulasitiki ezithambile eziyinhlanganisela, ezisebenzisa okunamathelisa ukuhlanganisa izingqimba ezimbili noma ngaphezulu zezinto zefilimu yepulasitiki ndawonye, ​​njenge-OPP/LLDPE, NY/LLDPE, njll., ezinobufakazi obuhle bomswakama, obukwazi ukumelana nokubanda, kanye nezakhiwo ezimelana nokubhoboza;

Isigaba sesithathu izikhwama zokupakisha zepulasitiki ezinwebekayo ezinezingqimba eziningi, lapho izinto ezingavuthiwe ezinemisebenzi ehlukene efana ne-PA, PE, PP, PET, EVOH, njll. zincibilika futhi zikhishwe ngokuhlukana, zihlanganiswe ku-main die, bese emva kwalokho. kuhlanganiswe ndawonye ngemva kokubunjwa kokushaywa nokupholisa., lolu hlobo lwezinto eziphathekayo alusebenzisi ama-adhesives futhi lunezici zokungangcolisi, umgoqo ophezulu, amandla aphezulu, ukumelana nokushisa okuphezulu nokuphansi, njll.
