Njengoba sonke sazi, izikhwama zokupakisha zingabonakala yonke indawo ekuphileni kwethu kwansuku zonke, kungaba sezitolo, ezitolo ezinkulu, noma ezinkundleni zokuxhumana nge-inthanethi. Izikhwama zokupakisha zokudla ezahlukahlukene eziklanywe kahle, ezisebenzayo, nezilula zingabonakala yonke indawo. Zisebenza njengesendlalelo sokuvikela noma sokuvimbela ukudla, njenge-"suit yokuvikela" yokudla.
Akugcini nje ngokugwema ngempumelelo izici ezimbi zangaphandle, njengokugqwala kwamagciwane, ukungcola kwamakhemikhali, ukubola kanye nezinye izingozi, ukuqinisekisa ikhwalithi nokuphepha kokudla ngesikhathi sokugcina nokuthuthwa, nokwandisa isikhathi sakho sokuhlala eshalofini, kungadlala indima yokukhushulwa kwabakhiqizi bokudla, kubulale izinyoni eziningi ngetshe elilodwa. Ngakho-ke, ngezinga elikhulu, izikhwama zokupakisha sezibe yingxenye ebalulekile yemikhiqizo yokudla ehlukahlukene.
Lokhu kuphinde kwakhulisa kakhulu imakethe yezikhwama zokupakisha. Ukuze bathathe indawo emakethe yezikhwama zokupakisha ukudla, abakhiqizi abakhulu bayaqhubeka nokuthuthukisa ikhwalithi yezinto zokupakisha futhi bathole izinhlobo ezahlukene zezikhwama zokupakisha ukudla. Lokhu futhi kuye kwaletha izinketho kubakhiqizi bokudla ngezinga elikhulu.
Kodwa-ke, ukudla okuhlukene kunezici ezihlukile, ngakho ukudla okuhlukene kunezidingo ezihlukile zokuvikela zokupakisha. Isibonelo, amaqabunga etiye athambekele ekungcoleni, ekuswakeni nasekukhumbeni, ngakho-ke adinga izikhwama zokupakisha ezinesivalo esihle, isithiyo esikhulu se-oxygen kanye ne-hygroscopicity enhle. Uma izinto ezikhethiwe zingahlangabezani nezici, ikhwalithi yamaqabunga etiye ayinakuqinisekiswa.
Ngakho-ke, izinto zokupakisha kufanele zikhethwe ngokwesayensi ngokwezakhiwo ezahlukene zokudla ngokwazo. Namuhla, i-Pack Mic (Shanghai Xiangwei Packaging Co., Ltd) yabelana ngesakhiwo sezinto ezithile zezikhwama zokupakisha ukudla. Izinto zokupakisha ukudla emakethe zifaka phakathi okulandelayo. Ngesikhathi esifanayo, izinto ezahlukene ziyahlanganiswa ngokwezici zokudla.
IQOQO LEZINTO ZOKUPHAKISHA UKUDLA
vIsilwane esifuywayo:
I-PET yi-polyethylene terephthalate, okuyi-polymer emhlophe njengobisi noma ephuzi elikhanyayo, ekristalu kakhulu. Inezici zokumelana nokushisa okuphezulu, ukuqina okuhle, umphumela omuhle wokuphrinta kanye namandla aphezulu.
vI-PA:
I-PA (Nylon, Polyamide) ibhekisela kupulasitiki eyenziwe nge-polyamide resin. Iyinto enezici ezinhle kakhulu zokuvimbela futhi inezici zokumelana nokushisa okuphezulu, amandla aphezulu, ukuguquguquka, izici ezinhle zokuvimbela, kanye nokumelana nokubhoboza.
vAL:
I-AL iyinto eyenziwe nge-aluminium foil enombala omhlophe njengesiliva, ekhanyayo, futhi ethambile kahle, izakhiwo zokuvimbela, ukuvaleka kokushisa, ukuvikela ukukhanya, ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana namafutha, kanye nokugcinwa kwephunga elimnandi.
vI-CPP:
Ifilimu ye-CPP yifilimu ye-polypropylene ephothiwe, eyaziwa nangokuthi ifilimu ye-polypropylene enwetshiwe. Inezici zokumelana nokushisa okuphezulu, ukuvaleka kahle kokushisa, izakhiwo ezinhle zokuvimbela, ezingenabo ubuthi futhi ezingenaphunga.
vI-PVDC:
I-PVDC, eyaziwa nangokuthi i-polyvinylidene chloride, iyinto yokuvimbela evikela ukushisa okuphezulu enezici ezifana nokumelana nomlilo, ukumelana nokugqwala, kanye nokuqina komoya okuhle.
vI-VMPET:
I-VMPET ifilimu embozwe nge-aluminium ye-polyester, okuyizinto ezinezici zokuvimbela eziphakeme futhi ezinezici ezinhle zokuvimbela umoya-mpilo, umhwamuko wamanzi kanye nephunga.
vI-BOPP:
I-BOPP (i-Biaxial Oriented Polypropylene) iyinto ebaluleke kakhulu yokupakisha eguquguqukayo enezici zokungabi nombala nokunganuki, amandla aphezulu okuthambekela, amandla okushaya, ukuqina, ukuqina kanye nokubonakala okuhle.
vI-KPET:
I-KPET iyinto enezici ezinhle kakhulu zokuvimba. I-PVDC imbozwe ku-substrate ye-PET ukuze ithuthukise izici zayo zokuvimba ngokumelene namagesi ahlukahlukene, ngaleyo ndlela ihlangabezana nezidingo zokupakisha ukudla okusezingeni eliphezulu.
IZAKHIWO EZIHLUKENE ZOKUPHAKISHA UKUDLA
Isikhwama sokupakisha sokuphendula
Njengoba isetshenziselwa ukupakisha inyama, izinkukhu, njll., ukupakisha kudinga izakhiwo ezinhle zokuvimbela, ukumelana nokudabuka, futhi kungahlanzwa ngaphansi kwezimo zokupheka ngaphandle kokuphuka, ukuqhekeka, ukuncipha, nokungabi nephunga. Ngokuvamile, isakhiwo sezinto sidinga ukukhethwa ngokuya ngomkhiqizo othize. Isibonelo, izikhwama ezisobala zingasetshenziswa ukupheka, kanti izikhwama ze-aluminium foil zifanelekela ukupheka okushisa okuphezulu. Inhlanganisela ethile yesakhiwo sezinto:
OkubonakalayoIzakhiwo Ezinobuthi:
I-BOPA/CPP, i-PET/CPP, i-PET/BOPA/CPP, i-BOPA/PVDC/CPP, i-PET/PVDC/CPP, i-GL-PET/BOPA/CPP
Ifoyili ye-aluminiumIzakhiwo zezinto ezifakwe i-laminate:
I-PET/AL/CPP, PA/AL/CPP, I-PET/PA/AL/CPP, I-PET/AL/PA/CPP
Izikhwama zokupakisha ukudla okulula ezikhukhumele
Ngokuvamile, ukudla okukhukhumele kuhlangabezana kakhulu nezici zokuvimbela umoya-mpilo, ukuvimbela amanzi, ukuvikelwa kokukhanya, ukumelana namafutha, ukugcinwa kwamakha, ukubukeka okuqinile, umbala ogqamile, kanye nezindleko eziphansi. Ukusetshenziswa kwenhlanganisela yesakhiwo sezinto ze-BOPP/VMCPP kungahlangabezana nezidingo zokupakisha zokudla okulula okukhukhumele.
Isikhwama sokupakisha samabhisikidi
Uma kuzosetshenziswa ekupakisheni ukudla okufana namabhisikidi, isikhwama sezinto zokupakisha kumele sibe nezakhiwo ezinhle zokuvimbela, izakhiwo eziqinile zokuvikela ukukhanya, ukumelana namafutha, amandla aphezulu, awanaphunga futhi awanambitheki, futhi aguquguquka. Ngakho-ke, sikhetha inhlanganisela yesakhiwo sezinto ezifana ne-BOPP/EXPE/VMPET/EXPE/S-CPP.
Isikhwama sokupakisha sobisi oluyimpuphu
Isetshenziselwa ukupakisha i-milk powder. Isikhwama sokupakisha sidinga ukuhlangabezana nezidingo zokuphila isikhathi eside eshalofini, ukulondolozwa kwephunga nokunambitheka, ukumelana nokubola kanye nokubola, kanye nokumelana nokumuncwa komswakama kanye nokuhlangana. Ekupakisheni i-milk powder, isakhiwo sezinto ze-BOPP/VMPET/S-PE singakhethwa.
Isikhwama Sokupakisha Itiye Eliluhlaza
Ukuze uthole izikhwama zokupakisha itiye, ukuze uqinisekise ukuthi amaqabunga etiye ayawohloka, ashintshe umbala kanye nokunambitheka, khetha i-BOPP/AL/PE, i-BOPP/VMPET/PE, i-KPET/PE
Isakhiwo sezinto ezibonakalayo singavimbela kangcono iphrotheni, i-chlorophyll, i-catechin, kanye ne-vitamin C equkethwe etiyeni eliluhlaza ukuthi ingangcoliswa.
Lokhu okungenhla kungenye yezinto zokupakisha ukudla i-Pack Mic ekuhlanganisele zona nokuthi ungahlanganisa kanjani imikhiqizo ehlukene. Ngiyethemba ukuthi kuzokusiza :)
