Ukudla okuhlukene kufanele kukhethe izikhwama zokudla ezinezakhiwo ezahlukene zezinto ezibonakalayo ngokwezici zokudla, ngakho-ke hlobo luni lokudla olufanele uhlobo luni lwesakhiwo sezinto ezibonakalayo njengezikhwama zokudla? Umkhiqizi wokupakisha ochwepheshe oguquguqukayo we-Shunfa ukupakisha ukuze akuchazele, isidingo sezikhwama zokupakisha zokudla ezenziwe ngokwezifiso amakhasimende angabhekisela kuso.
1. Isikhwama sokupheka
Izidingo zomkhiqizo:
Isetshenziselwa ukupakisha inyama, izinkukhu, njll., idinga ukuvimba okuhle kokupakisha, ukumelana nokuphuka kwemigodi yamathambo, ukubulala amagciwane ngaphansi kwezimo zokupheka, akukho ukuqhekeka, akukho ukuncibilika, akukho phunga.
Isakhiwo somklamo:
Ikilasi elicacile: 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, amandla aphezulu.
I-PA: Ukumelana nokushisa okuphezulu, amandla aphezulu, ukuguquguquka, isithiyo esihle, ukumelana nokubhoboza.
AL: Isithiyo esingcono kakhulu, ukumelana nokushisa okuphezulu.
I-CPP: Izinga lokupheka lokushisa eliphezulu, ukuvala ukushisa okuhle, akunabo ubuthi futhi akunambitheki.
I-PVDC: izinto zokuvimbela ukushisa okuphezulu.
I-GL-PET: ukugqoka ngomusi we-ceramic, isithiyo esihle, ukungena kwe-microwave.
Ukuze imikhiqizo ethile ikhethe isakhiwo esifanele, izikhwama ezikhanyayo zisetshenziswa kakhulu ekuphekeni, kanti izikhwama ze-AL foil zingasetshenziswa ekuphekeni okushisa okuphezulu kakhulu.
2. Isikhwama sokupakisha ukudla okulula esingeziwe
Izidingo zomkhiqizo: ukumelana nomoya-mpilo, ukumelana namanzi, ukumelana nokukhanya, ukumelana namafutha, ukuvikelwa kwamakha, ukubukeka, umbala ogqamile, izindleko eziphansi.
Isakhiwo somklamo:
I-BOPP/VMCPP
Isizathu:
Kokubili i-BOPP ne-VMCPP ziyaklwebheka, i-BOPP iyakwazi ukuphrinta kahle futhi icwebezela kakhulu. I-VMCPP inamandla amahle okuvimba futhi igcina iphunga nomswakama. I-CPP nayo inokumelana okuhle namafutha.
3. Isikhwama samakhukhi
Izidingo zomkhiqizo:
Isithiyo esihle, ukufiphaza okunamandla kokukhanya, ukumelana namafutha, amandla aphezulu, ayinaphunga futhi ayinambitheki, ukupakisha kuyaklwebheka kakhulu.
Isakhiwo somklamo:
I-BOPP/EXPE/VMPET/EXPE/S-CPP
Isizathu:
I-BOPP inokuqina okuhle, ukuphrinta okuhle kanye nezindleko eziphansi. I-VMPET inokumelana okuhle, ukukhanya, umoya-mpilo kanye namanzi. I-S-CPP inokuvala ukushisa okuhle okuphansi kanye nokumelana namafutha.
4. Isikhwama sokupakisha sobisi oluyimpuphu
Izidingo zomkhiqizo:
Ihlala isikhathi eside eshalofini, ukuvikelwa kokunambitheka, ukuwohloka kokulwa nokubola kwe-oxidation, ukwakheka kokulwa nomswakama.
Isakhiwo somklamo:
I-BOPP/VMPET/S-PE
Isizathu:
I-BOPP inokunyatheliswa okuhle, ukukhazimula okuhle, ukuqina okuhle kanye nentengo ephakathi.
I-VMPET inesici esihle sokuvimbela ukungcola, ukugwema ukukhanya, ukuqina okuhle, ukukhanya kwensimbi kanye ne-PET aluminium plating ethuthukisiwe kuyathandwa, enesendlalelo se-AL esijiyile. I-S-PE inesici esihle sokuvala ukungcola kanye nesici sokuvala ukushisa esiphansi.
5. Izikhwama zetiye
Izidingo zomkhiqizo:
Ilwa nokuwohloka, ukulwa nokushintsha kombala, ukulwa nokunambitheka, okungukuthi, ukuvimbela ukubola kwamaprotheni, i-chlorophyll, i-catechuic acid kanye ne-vitamin C equkethwe etiyeni.
Isakhiwo somklamo:
I-BOPP/AL/PE, BOPP/VMPET/PE, KPET/PE
Isizathu:
I-AL foil, i-VMPET, i-KPET ziyizinto ezinhle kakhulu zokuvimbela, isithiyo esihle ku-oxygen, umhwamuko wamanzi, iphunga. I-AK foil, ukumelana nokukhanya kwe-VMPET nakho kuhle kakhulu. Umkhiqizo unentengo ephakathi.
6. Gaya izikhwama zekhofi
Izidingo zomkhiqizo:
Ilwa nokumuncwa kwamanzi, ilwa nokumuncwa, imelana nesigaxa esiqinile somkhiqizo ngemva kokuhlanza nge-vacuum, ukugcina ikhofi ishintshashintsha, kulula ukuyixuba nephunga.
Isakhiwo somklamo:
I-PET/PE/AL/PE, PA/VMPET/PE
Isizathu:
I-AL, i-PA, i-VMPET inesivikelo esihle, ukumelana namanzi nomoya, kanti i-PE inesivikelo esihle sokushisa.
7. Izikhwama zokupakisha zetshokolethi
Izidingo zomkhiqizo:
Isithiyo esihle, gwema ukukhanya, ukuphrinta okuhle, uphawu lokushisa oluphansi.
Isakhiwo somklamo:
I-polish/inki yetshokolethi emsulwa/i-BOPP emhlophe/i-PVDC/ Ingcina yesivalo esibandayo
I-nut chocolate gloss oil/inki /VMPET/AD/BOPP/PVDC/ ingcina yesivalo esibandayo
Isizathu:
I-PVDC, i-VMPET yizinto ezivimbela kakhulu, i-glue yokuvala ebandayo ingavalwa ekushiseni okuphansi kakhulu, ukushisa ngeke kuthinte ushokoledi, ngoba i-kernel iqukethe uwoyela omningi, ukuwohloka kwe-oxidation kulula, ngakho-ke isakhiwo sokwanda kwengqimba yokuvimba umoya-mpilo.
