Itiye eliluhlaza ikakhulukazi liqukethe izakhi ezifana ne-ascorbic acid, ama-tannins, amakhompiyutha e-polyphenolic, amafutha e-catechin nama-carotenoids. Lezi zithako zithambekele ekuwohlokeni ngenxa ye-oksijini, izinga lokushisa, umswakama, iphunga elikhanyayo nelimo. Ngakho-ke, lapho ukupakipha itiye, ithonya lalezi zinto ezingenhla kufanele libe buthaka noma livinjelwe, futhi izidingo ezithile zinjengokulandelayo:
Ukumelana nomswakama
Okuqukethwe kwamanzi etiyeni akufanele kwedlule ama-5%, futhi ama-3% ahamba phambili ngokugcina isikhathi eside; Ngaphandle kwalokho, i-ascorbic acid etiyeni izobola kalula, futhi umbala, iphunga nokunambitheka kwetiye kuzoshintsha, ikakhulukazi emazingeni okushisa aphezulu. , izinga lokuwohloka lizosheshiswa. Ngakho-ke, izinto zokupakisha ezinokusebenza okuhle okunomswakama-ubufakazi zingakhethwa ngokupakishwa kobufakazi bokuma umswakama, njengamafilimu ahlanganisiwe asuselwa ku-aluminium foil foil noma ifilimu evulekile kakhulu. Ukunakwa okukhethekile kufanele kukhokhelwe ukwelashwa komswakama-ubufakazi bokupakishwa kwetiye elimnyama.
Ukumelana ne-Oxidation
Okuqukethwe komoya-mpilo kwiphakheji kufanele kulawulwe ngaphansi kwe-1%. I-oksijini eningi kakhulu izobangela ezinye izakhi ezisetiyeni ziwohloka. Isibonelo, i-Ascorbic acid ifakwa kalula kwi-deoxyascorbic acid, futhi iphinde ihlanganise nama-amino acid ukuze aphendule nge-pigment, okwenza ukunambitheka kwetiye kube kubi. Kusukela amanoni etiye aqukethe inani elithile lama-acid angenasisekelo, ama-acid anamafutha angenasisekelo angakwazi ukukhiqiza ngokuzenzakalelayo amakhompiyutha e-Aldehydes anjenge-Aldehydes nama-Enol amakhompiyutha anyamalale, futhi umbala uba mnyama.
Ukuhlangulela
Njengoba itiye liqukethe i-chlorophyll nezinye izinto, lapho ukupakisha amaqabunga itiye, ukukhanya kufanele kuvikelwe ukuvikela ukusabela kwe-photocatalytic kwe-chlorophyll nezinye izinto. Ngaphezu kwalokho, imisebe ye-ultraviolet nayo iyinto ebalulekile ekubangeleni ukuwohloka kwamaqabunga etiye. Ukuxazulula izinkinga ezinjalo, ubuchwepheshe bokupakisha abanomthunzi bungasetshenziswa.
Isithiyo segesi
Iphunga lamaqabunga etiye lilahleka kalula, nezinto zokwakha umoya omuhle kufanele zisetshenziselwe ukufakwa okulonda iphunga. Ngaphezu kwalokho, amaqabunga etiye alula kakhulu ukudonsa iphunga langaphandle, ukuze iphunga lamaqabunga itiye lithelelekile. Ngakho-ke, iphunga elikhiqizwa ngezinto zokupakisha kanye nobuchwepheshe bokupakisha kufanele lilawulwe ngokuqinile.
Ukushisa okuphezulu
Ukwanda kwezinga lokushisa kuzosheshisa ukusabela kwe-oxidation kwamaqabunga etiye, futhi ngasikhathi sinye kuzodala ukuthi ingabe ingaphezulu libe yi-gloss of itiye lihle liphele. Ngakho-ke, amaqabunga etiye alungele ukugcinwa emazingeni okushisa aphansi.
I-Composite Film Paka Packaging
Njengamanje, ukufakwa kwetiye okwengeziwe emakethe kuhlanganiswa ngaphakathiIzikhwama zefilimu eziyinhlanganisela. Kunezinhlobo eziningi zamafilimu ahlanganisiwe wetiye lokupakisha, njenge-maxio-proollophane / Polyethylene / I-Aluminium Foil / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene / Polyethylene, njll. Inesithiyo esihle kakhulu segesi izakhiwo, ukumelana nomswakama, amakha Ukugcinwa, nephunga elimelene nelivelele. Ukusebenza kwefilimu eliyinhlanganisela nge-aluminium foil kuphakeme ngokwengeziwe, njengokuphamba okuhle njalonjalo. Kunezindlela ezahlukahlukene zokupakisha zezikhwama zefilimu ezihlanganisiwe, kufaka phakathi ukubekwa uphawu okunezinhlangothi ezintathu,Izipuni zokusukuma,izindawo zokusukuma ngewindows ecacilenokugoqa. Ngaphezu kwalokho, isikhwama sefilimu esiyinhlanganisela sinokuphrinta okuhle, futhi kuzoba nomphumela oyingqayizivele lapho kusetshenziselwa ukuthengiswa kokuthengisa kokuthengisa.
