Ukudla okuhlukene kudingeka kukhethwe izikhwama zokupakisha ukudla ezinezakhiwo ezahlukene zezinto ezibonakalayo ngokwezici zokudla, ngakho-ke hlobo luni lokudla olufanele uhlobo luni lwesakhiwo sezinto ezibonakalayo njengezikhwama zokupakisha ukudla? Amakhasimende ahlela izikhwama zokupakisha ukudla ngendlela oyifisayo angabhekisela kukho.
1. Isikhwama sokupakisha esiphendukayo Izidingo zomkhiqizo: Sisetshenziselwa ukupakisha inyama, izinkukhu, njll. Kuyadingeka ukuthi iphakethe libe nezakhiwo ezinhle zokuvimba, ukumelana nokuphuka kwemigodi yamathambo, futhi lihlanzwe ngaphansi kwezimo zokupheka ngaphandle kokuphuka, ukuqhekeka, ukuncipha, kanye nephunga elingavamile.
Isakhiwo somklamo: Isigaba esibonakalayo: BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPP, PET/PVDC/CPP, GL-PET/BOPA/CPP
Ifoyili ye-aluminium: PET/AL/CPP, PA/AL/CPP, PET/PA/AL/CPP, PET/AL/PA/CPP
Isizathu: I-PET: ukumelana nokushisa okuphezulu, ukuqina okuhle, ukuphrinta okuhle kanye namandla aphezulu.
I-PA: ukumelana nokushisa okuphezulu, amandla aphezulu, ukuguquguquka, izakhiwo ezinhle zokuvimbela, ukumelana nokubhoboza.
AL: Izakhiwo ezinhle kakhulu zokuvimbela, ukumelana nokushisa okuphezulu.
I-CPP: izinga lokupheka lokushisa eliphezulu, ukuvala ukushisa okuhle, akunabungozi futhi akunambitheki.
I-PVDC: Izinto ezivimbela ukushisa okuphezulu.
I-GL-PET: ifilimu yokufaka umhwamuko we-ceramic, isici esihle sokuvimbela, idlulisela i-microwave.
Khetha isakhiwo esifanele semikhiqizo ethile, iningi lezikhwama ezisobala zisetshenziselwa ukupheka, kanti izikhwama ze-AL foil zingasetshenziswa ekuphekeni okushisa okuphezulu kakhulu.
2. Izikhwama zokupakisha ukudla okulula ezikhukhumele
Izidingo zomkhiqizo: Ukumelana nomoya-mpilo, ukumelana namanzi, ukuvikelwa kokukhanya, ukumelana namafutha, ukulondolozwa kwephunga, ukubukeka okuklwebhekayo, imibala ekhanyayo kanye nezindleko eziphansi.
Isakhiwo somklamo: BOPP/VMCPP
Isizathu: I-BOPP ne-VMCPP ziyaklwebheka kakhulu, i-BOPP iyakwazi ukuphrinta kahle futhi icwebezela kakhulu. I-VMCPP inezakhiwo ezinhle zokuvimba, igcina iphunga futhi ivimbela umswakama. Ukumelana namafutha e-CPP nakho kungcono.
3. Isikhwama sokupakisha samabhisikidi
Izidingo zomkhiqizo: izakhiwo ezinhle zokuvimbela, umthunzi oqinile, ukumelana namafutha, amandla aphezulu, ayinaphunga futhi ayinambitheki, futhi ukupakishwa kuyaklwebheka kakhulu.
Isakhiwo somklamo: BOPP/EXPE/VMPET/EXPE/S-CPP
Isizathu: I-BOPP inokuqina okuhle, ukuphrinta okuhle kanye nezindleko eziphansi. I-VMPET inezakhiwo ezinhle zokuvimbela, igwema ukukhanya, umoya-mpilo, namanzi. I-S-CPP inokuvala ukushisa okuhle okuphansi kanye nokumelana nowoyela.
4. Izikhwama zokupakisha zempuphu yobisi
Izidingo zomkhiqizo: isikhathi eside sokugcinwa, iphunga elimnandi kanye nokunambitheka, ukonakala kwe-anti-oxidative, ukwakheka kwe-anti-moisture caking.
Isakhiwo somklamo: BOPP/VMPET/S-PE
Isizathu: I-BOPP inokuphrintwa okuhle, ukucwebezela okuhle, ukuqina okuhle kanye nentengo ephakathi.
I-VMPET inezakhiwo ezinhle zokuvimbela, igwema ukukhanya, inokuqina okuhle, futhi inokukhanya kwensimbi. Kungcono ukusebenzisa i-PET aluminium plating eqinisiwe, futhi ungqimba lwe-AL lujiyile. I-S-PE inokuvala okuhle kokulwa nokungcola kanye nokuvala ukushisa okuphansi.
5. Izikhwama zetiye eziluhlaza
Izidingo zomkhiqizo: ukulwa nokuwohloka, ukulwa nokushintsha kombala, ukulwa nephunga, okungukuthi, ukuvimbela ukubola kwamaprotheni, i-chlorophyll, i-catechin, kanye ne-vitamin C equkethwe etiyeni eliluhlaza.
Isakhiwo sokuklama: BOPP/AL/PE, BOPP/VMPET/PE, KPET/PE
Isizathu: I-AL foil, i-VMPET, i-KPET zonke ziyizinto ezinezici ezinhle kakhulu zokuvimbela, futhi zinezimfanelo ezinhle zokuvimbela umoya-mpilo, umhwamuko wamanzi kanye nephunga. I-AK foil kanye ne-VMPET nazo zinezimfanelo ezinhle kakhulu zokuvikela ukukhanya. Intengo yomkhiqizo iphakathi.
6. Izikhwama zekhofi ezigayiwe
Izidingo zomkhiqizo: Ukulwa nokumuncwa kwamanzi, ukulwa nokumuncwa, ukumelana nezigaxa eziqinile zomkhiqizo ngemva kokuhlanza nge-vacuum, kanye nokugcina iphunga lekhofi elishintshashintshayo nelilula ukumuncwa.
Isakhiwo sokuklama: PET/PE/AL/PE, PA/VMPET/PE
Izizathu: I-AL, i-PA, i-VMPET inezakhiwo ezinhle zokuvimba, izakhiwo zokuvimba amanzi negesi, kanti i-PE inezakhiwo ezinhle zokuvala ukushisa.
7. Izikhwama zokupakisha zetshokolethi
Izidingo zomkhiqizo: izakhiwo ezinhle zokuvimbela, gwema ukukhanya, ukuphrinta okuhle, ukuvala ukushisa okuphansi.
Isakhiwo somklamo: i-chocolate varnish emsulwa/inki/i-BOPP emhlophe/i-PVDC/i-cold sealant
I-brownie Varnish/Ink/VMPET/AD/BOPP/PVDC/Cold Sealant
Isizathu: I-PVDC kanye ne-VMPET ziyizinto ezivimbela kakhulu. Iglue yokuvala ebandayo ingavalwa ekushiseni okuphansi kakhulu, futhi ukushisa ngeke kuthinte ushokoledi. Njengoba amantongomane aqukethe uwoyela omningi futhi evame ukuwohloka ngenxa ye-oxidative, ungqimba lwesithiyo se-oxygen luyanezelwa esakhiweni.
