Njengoba sonke sazi, izikhwama zokupakisha zingabonakala yonke indawo ezimpilweni zethu zansuku zonke, kungaba ezitolo, izitolo ezinkulu, noma amapulatifomu ezentengiselwano. Izikhwama zokupakisha zokudla ezahlukahlukene eziklanyelwe kahle, ezisebenzayo, nezihle futhi zibonakale yonke indawo. Isebenza njengesendlalelo esivikelekile noma esivimba ukudla, njengento "evikelayo" yokudla.
Hhayi nje kuphela ukugwema ngempumelelo izici ezingezinhle zangaphandle, njengokugqwala kwama-microbial, ukungcoliswa kwamakhemikhali, i-oxidation nezinye izingozi, futhi kudlulise nempilo yayo yokugcina, ukubulala izinyoni eziningi ngetshe elilodwa. . Ngakho-ke, ngezinga elikhulu, izikhwama zokupakisha seziyingxenye ebalulekile yemikhiqizo yokudla ehlukahlukene.
Lokhu kuye kwaqinisa kakhulu imakethe yezikhwama zokupakisha. Ukuze uhlale indawo emakethe yokupakisha yokudla, abakhiqizi abakhulu bayaqhubeka nokwenza ngcono ikhwalithi yezinto zokupakisha futhi bathole izikhwama zokupakisha zokudla ezahlukahlukene. Lokhu kuye kwaletha izinqumo kubakhiqizi bokudla ngezinga elikhulu.
Kodwa-ke, ukudla okuhlukile kunezici ezihlukile, ngakho-ke ukudla okuhlukile kunezidingo ezihlukile zokuvikela zokupakishwa. Isibonelo, amaqabunga etiye athambekele kwi-oxidation, umswakama nokubumba, ngakho-ke adinga izikhwama zokupakisha ngokubekwa kahle uphawu, umgoqo ophakeme we-oksijini nokuhlambalaza okuhle. Uma impahla ekhethiwe ingahlangabezani nezimpawu, ikhwalithi yamaqabunga etiye awakwazi ukuqinisekiswa.
Ngakho-ke, izinto zokupakisha kufanele zikhethwe ngokwesayensi ngokuya ngezakhiwo ezahlukahlukene zokudla uqobo. Namuhla, pack mic (Shanghai Xiangwei Packaling Co, Ltd) yabelana ngesakhiwo sezinto ezibonakalayo zezikhwama ezithile zokupakisha zokudla. Izinto zokupakisha zokudla emakethe ikakhulukazi zibandakanya okulandelayo. Ngasikhathi sinye, izinto ezahlukahlukene zihlanganiswa ngokuya ngezimpawu zokudla.
Ukuqoqwa Kwezinto Zokudla Zokudla
vPet:
I-PETYETHYLEne Terephthalate, okuyi-Milky White White noma Uphuzi ophuzi, u-crystalline polymer. Inezici zokumelana okuphezulu okuphezulu, ubulukhuni obuhle, umphumela omuhle wokuphrinta namandla aphezulu.
vPA:
I-PA (nylon, i-polyamide) ibhekisela epulasitiki eyenziwe nge-polyamide resin. Kuyinto ebonakalayo enezinto ezinesithiyo esihle kakhulu futhi inezimpawu zokumelana okuphezulu kakhulu, amandla aphezulu, ukuguquguquka, izakhiwo ezinhle zokuvimba, nokumelana nokugqwala.
vAl:
I-AL iyinto ebonakalayo ye-aluminium foil okumhlophe okumhlophe, okukhanyayo, futhi okuthambile, izithiyo zokuvilapha, ukumelana nokushisa, ukumelana kwamazinga okushisa, ukumelana namafutha, nokugcinwa kwamafutha, kanye nokugcinwa kwamafutha.
vI-CPP:
Ifilimu le-CPP yi-Polypropylene film, eyaziwa nangokuthi ifilimu ye-polypropylene eyeluliwe. Inezici zokumelana okuphezulu okushisa okuphezulu, ukuncipha kokushisa okuhle, izakhiwo ezinhle zokuvimbela, okungezona ubuthi nodoli.
vI-PVDC:
I-PVDC, eyaziwa nangokuthi i-polyvinylidene chloride, iyisithiyo sokuvimbela izinga lokushisa okuphezulu kakhulu okuhambisana nokumelana kwamalangabi, ukumelana nokuqina, kanye nokuqina komoya okuhle.
vVmpete:
I-vmpet yi-polyester aluminium-ehlanganisiwe ifilimu, okuyinto enezinto ezibonakalayo ezinezindawo eziphakeme eziphezulu futhi inezakhiwo ezinhle zokuvimbela umoya-mpilo, umphunga wamanzi nephunga.
vI-BOPP:
I-BOPP (I-Biaxeint Orient Polypropylene) iyinto ebaluleke kakhulu yokufaka eguquguqukayo enezimpawu ezinamandla angenamibala namaphunga, amandla aphezulu, amandla aphansi, amandla anomthelela, ukuqina, ubulukhuni nokubonakala okuhle.
vKpet:
I-Kper iyinto enezinto ezinhle kakhulu zesithiyo. I-PVDC ihlanganiswe engxenyeni yesilwane esifuywayo ukuze ithuthukise izakhiwo zayo ezivimbe ngokumelene namagesi ahlukahlukene, ngaleyo ndlela ihlangabezane nezidingo zokupakishwa kokudla okuphezulu.
Izakhiwo ezahlukene zokupakisha ukudla
Buyisela isikhwama sokufaka
Isetshenziselwa ukupakishwa kwenyama, izinkukhu, njll. Ngokuvamile, ukwakheka kwezinto ezibonakalayo kudinga ukukhethwa ngokuya ngomkhiqizo othize. Isibonelo, izikhwama ezibonakalayo zingasetshenziselwa ukupheka, futhi izikhwama ze-aluminium foil zilungele ukupheka okushisa kakhulu. Inhlanganisela yesakhiwo esithile:
-KhanyayoIzakhiwo ezihlanzekile:
I-BOPA / CPP, PET / CPP, Pet / Bopa / CPP, Bopa / PVDC / CPP / CPP / CPP / CPP / CPP / CPP
I-Aluminium Foilizinhlaka zezinto ezibonakalayo:
I-Pet / Al / CPP, PA / AL / CPP, Pet / PPP, PE / PPP, PET / AL / CPP, PET / AL / PA / CPP
Ukhukhumeze izikhwama zokupakisha zokudla okumnandi
Ngokuvamile, ukudla okukhukhumeze kuhlangabezana nezimpawu zomzimba we-oksijini, isithiyo samanzi, ukuvikelwa kokukhanya, ukumelana kawoyela, ukugcinwa kwamafutha, ukugcinwa kwamakha, umbala okhanyayo nezindleko eziphansi. Ukusetshenziswa kwenhlanganisela yesakhiwo se-bopp / vmcPP kungahlangabezana nezidingo zokupakisha zokudla okulula.
Isikhwama sokupakisha nge-Biscuit
Uma kufanele isetshenziselwe ukupakishwa kokudla okufana namabhisikidi, isikhwama sezinto ezisetshenziswayo kufanele ibe nezithiyo ezinhle, izakhiwo eziqinile zokuvikela ukukhanya, ukumelana kawoyela, amandla aphezulu, angenamkhawulo futhi angenamkhawulo. Ngakho-ke, sikhetha inhlanganisela yokwakheka kwezinto ezibonakalayo efana ne-BOPP / Expe / vmpet / expe / S-CPP.
Isikhwama sokupakisha ubisi
Isetshenziselwa ukupakishwa komoya. Isikhwama sokupakisha sidinga ukufeza izidingo zempilo ende eshalofini, iphunga nokulondolozwa kokunambitha, ukumelana ne-oxidation kanye nokuwohloka, kanye nokumelana nokuvinjwa komswakama kanye nokuqina. Okokupakishwa kobisi kwe-powder, i-bopp / vmpet / s-PE (S-PE Pe
Isikhwama sokupakisha e-Green Tea
Ukuze uthole izikhwama zokupakipha kwetiye, ukuze uqinisekise ukuthi amaqabunga etiye awohloka, ashintshe umbala nokunambitha, khetha i-BOPP / Al / PE, i-BPET / PE
Isakhiwo esibonakalayo singavimba kangcono amaprotheni, i-chlorophyll, i-catechin, ne-vithamini C equkethwe itiye eliluhlaza kusuka ekubeni yi-oxidised.
Lokhu okungenhla kungenye yezinto zokupakisha zokudla ezipakisha i-MIC zikuhlanganisele wena nokuthi ungahlanganisa kanjani imikhiqizo ehlukene. Ngiyethemba kuzokusiza :)
