Ukupakisha okuguquguqukayo kwekhava yebhamuza kuyindlela yokupakisha yangaphandle esetshenziswa kakhulu yezemithi, isikhathi esiningi izinhlobonhlobo zezinto zokukhiqiza eziyinhlanganisela, lokhu impahla plastic sheet I-FTTP Aluminium Blimang Foil isembozo emaphaketheni esetshenziswa base material, okuvame kakhulu i-polyvinyl chloride ishidi eliqinile (Ishidi eliqinile le-PVC elifushane), Ukufakwa kwekhava yebhamuza sekudlule isikhathi eside, Kusukela ukwamukelwa ukukhiqizwa blister emaphaketheni, isisekelo – Izinto ze-PVC zisetshenziselwa ukuqedela ukupakishwa kwe-blister yezidakamizwa. Impahla inezindawo eziningi ezinhle futhi ishibhile futhi isezingeni eliphezulu, kodwa futhi inobubi obungacacile. Ngokwesibonelo, Ukukhiqizwa kwe-PVC noma inqubo yokusebenzisa izoba nomthelela othile emvelweni. Ngesikhathi sokukhiqiza, amanye amagesi e-vinyl chloride angafuneki kwesinye isikhathi akhiqizwa ahlanganiswe nezinye izingxube.

Ukulungiswa kwe PVC yokwelapha idinga ukwengeza ezinye izingxenye, njenge-plasticizer, isitabili, njalo njalo. Umkhiqizo uzinzile ekusebenzeni futhi ngeke ubangele noma yikuphi ukulimala okuqondile emzimbeni womuntu, kodwa ngemva kokusetshenziswa, ezinye izindawo zizoshiswa lapho kulungiswa imfucuza yokupakisha, kanye nokushiswa kwe-PVC kuzokhiqiza imikhiqizo efana ne-dioxin hydrochloric acid. Lokhu kunomthelela othile endaweni ezungezile.

Amanye amazwe nezifunda, ukuze kuqedwe ukuvela kwalolu hlobo lokungcola, bayekile ukusetshenziswa kwe-PVC blister package, njengamanye amabhizinisi emithi eJalimane. Izwe laseJapan futhi likhawulela ukukhiqizwa kwemikhiqizo ye-PVC, lokhu kungokwalabo bonke abakhiqizi bemithi ukuthi bakuqaphele, ukusetshenziswa okusabalele kwamanje kwamashidi e-PVC njengento yokupakisha yamabhamuza ekhemisi kungenzeka ngenxa yokuthi indawo ezungezile noma inqubo yokukhiqiza ezinye izinto eziyingozi futhi inciphisa kancane ukusetshenziswa., uma ikusasa kuleli fomu lingathuthukisiwe, lo mkhiqizo uzoqedwa kancane kancane.

Ukuze uthuthukise kangcono ukushiyeka kwempahla ye-PVC yokwelapha, ukuze le nto ikwazi ukuhlangabezana kangcono nezidingo zokupakishwa kwemithi, izimboni zemithi manje seziqala ukusebenzisa ishidi eliqinile eliyinhlanganisela ye-PVC, leli shidi eliyinhlanganisela ikakhulukazi lakhiwe ishidi eliqinile le-PVC kanye nelinye noma amafilimu amasha we-polymer amasha, ifilimu yokuxuba. Ngokukhipha, inhlanganisela, umgwengwezi, indlela yokwenza imishini yokukhiqiza kanye nenhlanganisela yenoveli ukuze kuhlangatshezwane nezidingo zezinto zokupakisha ezenza imithi emakethe njengamanje ithandwa kakhulu ngamabhamuza yiphepha lepulasitiki le-aluminium., lolu hlobo lwe-aluminium foil ngokwayo, non-anobuthi, namanzi, Ukusebenza kwe-oxygen insulation kuhle, Imithi futhi kungaba isikhathi eside ngemuva kwezakhiwo zomuthi. Ngeke imunce kalula umswakama, isikhutha, ukuwohloka, njll., ikakhulukazi imithi yamaShayina Yendabuko, izidingo zezinto zokupakisha zidinga kakhulu.

Lapho umuthi upakishwa ngeminyaka yawo-1990, ukuphepha kokusetshenziswa kwezidakamizwa ukwanda kwamabhizinisi nabathengi abakunaka, ngoba ezinye izakhi zezidakamizwa zisengozini yokonakala, i-oxidation, ishidi lokuqala le-PVC alikwazanga ukuhlangabezana nezimfuneko zokupakishwa zale mithi. Imboni yezemithi ithuthukiswe ngempumelelo yaba yi-hard sheet ye-PVC njengento eyisisekelo, ngesisekelo sokuqala ukukhulisa ingxenye ephezulu ye-polymer material composite, ukwandisa i-PVC yasekuqaleni kuzo zonke izici zezici, njengenhlanganisela ye-PVC ne-PVDC, Inhlanganisela ye-PVC ne-PE, Inhlanganisela ye-PVC/PE/PVDC nokunye. Lezi zinto ezihlanganisiwe zihlanganisa ukuqina kweshidi eliqinile le-PVC, ukubumba okuhle, kanye nesithiyo esihle kumhwamuko wamanzi, umoya-mpilo, igesi ye-carbon dioxide, nazo zonke izinhlobo zephunga. Ingakwazi ukuhlangabezana nezidingo zokupakishwa kwezidakamizwa ezincibilika kalula futhi ezifakwe i-oxidized kalula kanye neminye yemithi Yendabuko YaseShayina edinga ukugcina iphunga.. Ngesikhathi esifanayo, ukusetshenziswa kwalawa madiski ayinhlanganisela kugcina imishini yokukhiqiza yokuqala, ngenkathi kunciphisa isithombe semvelo.
