Agasanduku ko gutekeshamo ka Zipper Foil gafite Oxygen Adsorbent

Agapaki k'inyuma ni agapaki k'ipulasitiki gakozwe mu buryo buvanze gashobora kuvurwa n'ubushyuhe, gafite ibyiza byo kuba udusanduku tw'ibikombe n'udukapu twa plastiki twihanganira amazi abira.
Ibiryo bishobora gusigara mu gikapu, bigashyirwamo umuti woroshye kandi bigashyushya ku bushyuhe bwinshi (ubusanzwe kuri 120 ~ 135°C), hanyuma bikajyanwa hanze kurira. Byamaze imyaka irenga icumi, ni igikoresho cyiza cyo gupakiramo. Bikwiriye gupakira inyama n'ibikomoka kuri soya, biroroshye, bifite isuku kandi ni ingirakamaro, kandi bishobora kugumana uburyohe bw'umwimerere bw'ibiryo, bukundwa n'abaguzi.
Mu myaka ya 1960, Leta Zunze Ubumwe za Amerika zavumbuye filime ikoze muri aluminiyumu-plastiki kugira ngo ikemure uburyo ibiryo byo mu kirere bipfunyikwamo. Ikoreshwa mu gupakira ibiryo by'inyama, kandi ishobora kubikwa ku bushyuhe bw'icyumba binyuze mu gushyushya ubushyuhe bwinshi no gusukura umuvuduko mwinshi, ikaba imara igihe kirenga umwaka 1. Uruhare rwa filime ikoze muri aluminiyumu-plastiki rusa n'urw'agacupa, koroshye kandi koroshye, bityo kitwa agacupa koroshye. Muri iki gihe, ibikomoka ku nyama bimara igihe kirekire bibikwa ku bushyuhe bw'icyumba, nko gukoresha ibikoresho bikomeye byo gupakira, cyangwa gukoresha amacupa y'ibirahure n'amacupa; iyo ukoresheje gupakira byoroshye, hafi ya byose bikoresha filime zikozwe muri aluminiyumu-plastiki.

Uburyo bwo gukora agapaki k’udupira duto duhangana n’ubushyuhe bwinshi. Muri iki gihe, udupaki twinshi two gukaraba ku isi dukora hakoreshejwe uburyo bwo gukaraba twumye, kandi duke dushobora no gukorwa hakoreshejwe uburyo bwo gukaraba twumye budafite solvent cyangwa uburyo bwo gukaraba twumye bukoresha co-extrusion. Ubwiza bwa dry compounding buri hejuru ugereranyije n’ubwo gukaraba twumye budafite solvent, kandi imiterere n’imvange y’ibikoresho birakwiye kandi ni byinshi kuruta co-extrusion compounding, kandi ni byiza kuyikoresha.

Kugira ngo huzuzwe ibisabwa mu mikorere y'agafuka k'inyuma, urwego rw'inyuma rw'inyubako rukozwe muri firime ya polyester ikomeye cyane, urwego rwo hagati rukozwe muri firime ya aluminiyumu irinda urumuri kandi idahumeka, naho urwego rw'imbere rukozwe muri firime ya polypropylene. Hariho imiterere y'urwego rutatu: PET/AL/CPP, PPET/PA/CPP; Imiterere y'urwego rune ni PET/AL/PA/CPP.
