Njengoba sonke sazi, izikhwama zokupakisha zingabonakala yonke indawo ezimpilweni zethu zansuku zonke, kungaba sezitolo, ezitolo ezinkulu, noma ezinkundleni zokuxhumana ze-e-commerce.Izinhlobonhlobo zezikhwama zokupakisha zokudla eziklanywe kahle, ezisebenzayo, nezilula zingabonakala yonke indawo.Isebenza njengesivikelo noma ungqimba wokudla, "njengesudi yokuvikela" yokudla.
Akukhona nje kuphela ukuthi ingagwema ngempumelelo izici ezingezinhle zangaphandle, njengokugqwala kwe-microbial, ukungcoliswa kwamakhemikhali, i-oxidation nezinye izingozi, iqinisekise ikhwalithi nokuphepha kokudla ngesikhathi sokugcina nokuhamba, futhi yandise impilo yayo yeshalofu, ingadlala indima yokuphromotha ukudla. abakhiqizi, ukubulala izinyoni eziningi ngetshe elilodwa..Ngakho-ke, ngokwezinga elikhulu, izikhwama zokupakisha seziyingxenye ebalulekile yemikhiqizo ehlukahlukene yokudla.
Lokhu kuphinde kwakhulisa kakhulu imakethe yezikhwama zokupakisha.Ukuze bathole indawo emakethe yezikhwama zokupakisha ukudla, abakhiqizi abakhulu bayaqhubeka nokuthuthukisa ikhwalithi yezinto zokupakisha futhi bathole izinhlobonhlobo zezikhwama zokupakisha zokudla.Lokhu kuphinde kwaletha ukukhetha kubakhiqizi bokudla ngezinga elikhulu.
Kodwa-ke, ukudla okuhlukahlukene kunezici ezihlukile, ngakho-ke ukudla okuhlukile kunezidingo ezihlukene zokuvikela zokupakishwa.Isibonelo, amaqabunga etiye athambekele ku-oxidation, umswakama kanye nesikhunta, ngakho-ke adinga izikhwama zokupakisha ezinokuvalwa okuhle, umgoqo ophezulu we-oxygen kanye ne-hygroscopicity enhle.Uma into ekhethiwe ingahlangabezani nezici, ikhwalithi yamaqabunga etiye ayikwazi ukuqinisekiswa.
Ngakho-ke, izinto zokupakisha kufanele zikhethwe ngokwesayensi ngokwezakhiwo ezihlukene zokudla ngokwazo.Namuhla, i-Pack Mic (Shanghai Xiangwei Packaging Co., Ltd) yabelana ngesakhiwo sempahla yezinye izikhwama zokupakisha ukudla.Izinto zokupakisha ukudla emakethe ikakhulukazi zihlanganisa okulandelayo.Ngesikhathi esifanayo, izinto ezihlukahlukene zihlanganiswa ngokuvumelana nezici zokudla.
UKUQOQA IZINTO ZOKUDLA ZOKUPAKASHA
vI-PET:
I-PET i-polyethylene terephthalate, eyi-milky emhlophe noma ephuzi ngokukhanyayo, i-polymer ecwebe kakhulu.Inezici zokumelana nokushisa okuphezulu, ukuqina okuhle, umphumela omuhle wokuphrinta namandla aphezulu.
vPA:
I-PA (Nylon, Polyamide) ibhekisela epulasitiki eyenziwe nge-polyamide resin.Kuyinto enezinto ezinhle kakhulu zokuvimbela futhi inezici zokumelana nokushisa okuphezulu, amandla aphezulu, ukuguquguquka, izakhiwo ezinhle zokuvimbela, kanye nokumelana nokubhoboza.
vAL:
I-AL iyinsimbi ye-aluminium foil emhlophe qhwa, ecwebezelayo, futhi inokuthamba okuhle, izakhiwo zokuvimbela, ukuvala ukushisa, ukuvikela ukukhanya, ukumelana nezinga lokushisa eliphezulu, ukumelana nezinga lokushisa eliphansi, ukumelana nowoyela, nokugcinwa kwephunga.
vI-CPP:
Ifilimu ye-CPP ifilimu ye-polypropylene, eyaziwa nangokuthi ifilimu ye-polypropylene enwetshiwe.Inezici zokumelana nokushisa okuphezulu, ukuvaleka kahle kokushisa, izakhiwo ezinhle zokuvimbela, ezingenabuthi futhi ezingenaphunga.
vI-PVDC:
I-PVDC, eyaziwa nangokuthi i-polyvinylidene chloride, iyinto evimbela ukumelana nokushisa okuphezulu enezici ezifana nokumelana nelangabi, ukumelana nokugqwala, kanye nokuqina komoya okuhle.
vI-VMPET:
I-VMPET ifilimu ye-polyester aluminium ehlanganiswe ne-aluminium, into enezinto ezivimbelayo ephezulu futhi enezici ezinhle zokuvimbela umoya-mpilo, umhwamuko kanye nephunga.
vI-BOPP:
I-BOPP (i-Biaxially Oriented Polypropylene) iyinto ebaluleke kakhulu yokupakisha eguquguqukayo enezici zokungabi nambala futhi ezingenaphunga, amandla aqinile aphezulu, amandla omthelela, ukuqina, ukuqina nokucaca okuhle.
vI-KPET:
I-KPET iyinto enezinto ezinhle kakhulu zokuthibela.I-PVDC imbozwe ku-substrate ye-PET ukuze ithuthukise izakhiwo zayo zokuvimbela ngokumelene namagesi ahlukahlukene, ngaleyo ndlela ihlangabezane nezidingo zokupakishwa kokudla okuphezulu.
IZAKHIWO ZOKUPAKA KOKUDLA EZhlukene
Buyisa isikhwama sokupakisha
Isetshenziselwa ukupakisha inyama, izinkukhu, njll., ukupakishwa kudinga izakhiwo ezinhle zokuthibela, ukumelana nezinyembezi, futhi kungenziwa inzalo ngaphansi kwezimo zokupheka ngaphandle kokuphuka, ukuqhekeka, ukuncipha, nokungabi naphunga.Ngokuvamile, isakhiwo sezinto ezibonakalayo sidinga ukukhethwa ngokuvumelana nomkhiqizo othile.Isibonelo, izikhwama ezisobala zingasetshenziselwa ukupheka, futhi izikhwama ze-aluminium foil zifanelekile ukupheka okuphezulu.Inhlanganisela yesakhiwo esikhethekile:
OkusobalaIzakhiwo ezine-Laminated:
I-BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPP, PET/PVDC/CPP, GL-PET/BOPA/CPP
I-aluminium foilimpahla laminated Izakhiwo:
I-PET/AL/CPP, PA/AL/CPP, PET/PA/AL/CPP, PET/AL/PA/CPP
Izikhwama zokupakisha ukudla okulula okuphuphuziwe
Ngokuvamile, ukudla okukhukhumele kuhlangabezana nezici zokuvimbela umoya-mpilo, umgoqo wamanzi, ukuvikela ukukhanya, ukumelana nowoyela, ukugcinwa kwephunga elimnandi, ukubukeka okuhlanzekile, umbala ogqamile, nezindleko eziphansi.Ukusetshenziswa kwenhlanganisela yesakhiwo se-BOPP/VMCPP kungahlangabezana nezidingo zokupakisha zokudla okulula okukhukhumele.
Isikhwama sokupakisha amabhisikidi
Uma sizosetshenziselwa ukupakisha ukudla okunjengamabhisikidi, isikhwama sempahla yokupakisha kumele sibe nezakhiwo ezinhle zokuthibela ukukhanya, izinto ezivikela ukukhanya okuqinile, ukumelana nowoyela, amandla aphezulu, ezingenaphunga futhi ezingenakunambitheka, nokupakishwa okuguquguqukayo.Ngakho-ke, sikhetha inhlanganisela yesakhiwo esibalulekile njenge-BOPP/EXPE/VMPET/EXPE/S-CPP.
Isikhwama sokupakisha sempushana yobisi
Isetshenziselwa ukupakisha impushana yobisi.Isikhwama sokupakisha sidinga ukuhlangabezana nezidingo zempilo yeshelufu ende, ukulondolozwa kwephunga nokunambitha, ukumelana ne-oxidation nokuwohloka, nokumelana nokumuncwa komswakama kanye nokuhlangana.Ngokupakishwa kwempushana yobisi, isakhiwo se-BOPP/VMPET/S-PE singakhethwa.
Isikhwama Sokufakwa Kwetiye Elihlaza
Ngezikhwama zokupakisha itiye, ukuze uqinisekise ukuthi amaqabunga etiye ayawohloka, ashintshe umbala nokunambitha, khetha i-BOPP/AL/PE, BOPP/VMPET/PE, KPET/PE
Isakhiwo sezinto ezibonakalayo singavimbela kangcono amaprotheni, i-chlorophyll, i-catechin, ne-vitamin C equkethwe etiyeni eliluhlaza ukuthi ifakwe i-oxidized.
Okungenhla ngezinye zezinto zokupakisha ukudla ezikuhlanganisele yona i-Pack Mic nokuthi ungayihlanganisa kanjani imikhiqizo ehlukene.Ngethemba ukuthi kuzoba usizo kuwe :)
