Iseti yengxowa yokupheka ye-Zipper Foil ene-Oxygen Adsorbent

Isikhwama sokuphendula yingxowa yeplastiki edityanisiweyo enokulungiswa ngobushushu, enezibonelelo zezikhongozeli ezisemathinini kunye neengxowa zeplastiki ezibilayo ezingangeni manzi.
Ukutya kungashiywa kuphelele ebhegini, kucocwe kwaye kufudunyezwe kubushushu obuphezulu (ngesiqhelo kwi-120 ~ 135°C), kuze kuthathwe kutyiwe. Njengoko sele kudlule iminyaka engaphezu kweshumi, sisitya esifanelekileyo sokupakisha esithengiswayo. Sifanelekile ekupakisheni inyama kunye neemveliso zesoya, silula, sicocekile kwaye siyasebenza, kwaye sinokugcina incasa yokuqala yokutya, ethandwa ngabathengi.
Kwiminyaka yoo-1960, i-United States yasungula ifilimu ye-aluminium-plastic composite ukuze isombulule ukupakishwa kokutya okuhamba emoyeni. Isetyenziselwa ukupakisha ukutya kwenyama, kwaye ingagcinwa kubushushu begumbi ngobushushu obuphezulu kunye nokucoca uxinzelelo oluphezulu, kunye nobomi beshelufu obungaphezu konyaka omnye. Indima yefilimu ye-aluminium-plastic composite ifana neye-can, ethambileyo kwaye ilula, ngoko ke ibizwa ngokuba yi-can ethambileyo. Okwangoku, iimveliso zenyama ezinobomi obude beshelufu zigcinwa kubushushu begumbi, njengokusebenzisa izikhongozeli zokupakisha eziqinileyo, okanye ukusebenzisa ii-tinplate cans kunye neebhotile zeglasi; ukuba usebenzisa ukupakisha okuguquguqukayo, phantse zonke zisebenzisa ii-aluminium-plastic composite films.

Inkqubo yokwenziwa kwesikhwama sokuphendula esimelana nobushushu obuphezulu Okwangoku, uninzi lweengxowa zokuphendula ehlabathini zenziwa ngendlela yokomisa eyomileyo, kwaye ezimbalwa zinokwenziwa ngendlela yokomisa eyomileyo okanye indlela yokomisa eyomileyo. Umgangatho wokomisa eyomileyo uphezulu kunowokomisa eyomileyo, kwaye ulungiselelo kunye nokudibanisa izixhobo kunengqondo kwaye kubanzi kunokomisa eyomisa eyomileyo, kwaye kuthembekile ngakumbi ukuyisebenzisa.

Ukuze kuhlangatyezwane neemfuno zokusebenza kwesingxobo sokujika, umaleko wangaphandle wesakhiwo wenziwe ngefilimu yepolyester enamandla aphezulu, umaleko ophakathi wenziwe ngefoyile ye-aluminium ekhusela ukukhanya, engangeni moya, kwaye umaleko wangaphakathi wenziwe ngefilimu ye-polypropylene. Kukho izakhiwo ezineeleya ezintathu: PET/AL/CPP, PPET/PA/CPP;Isakhiwo esineeleya ezine yiPET/AL/PA/CPP.
