Isitywina esiphumayo senziwe ngefilimu ephefumulayo kunye ne-Heat induction seal (HIS) ngokusebenzisa i-ultrasonic okanye i-hot melt welding, efezekisa ngokupheleleyo umphumo "wokuphefumula kunye nokungavuzi".Isitywina esiphumayo sinoyilo olulula, ukungeneka komoya okugqwesileyo kunye nokumelana okugqwesileyo kwi-surfactants.Le mveliso iphuhliswa ukukhusela isitya sokuzalisa (ibhotile) ukuba singashukunyiswa okanye sibekwe kumaqondo okushisa ahlukeneyo ukuvelisa igesi emva kokuzalisa i-liquid ethile, ngaloo ndlela ibangela ukuba i-container deform okanye i-cap cap.

I-Vented liner yeyona ndlela ibalaseleyo yokuhamba komoya kwishishini, iinketho ezininzi zokungena umoya zizalisekisa iimfuno ezahlukeneyo zokusebenza.Inikezelwe kwisiqwenga esinye sogwebu okanye iziqwenga ezibini zewax ezibotshelelwe kwipulp.

I-Vented liner ifanelekile kwi-PET, i-PVC, i-PS, i-PP, i-PE ... iibhotile zeplastiki kunye neebhotile zeglasi, kwaye isetyenziselwa kakhulu ukutya, izinto zokuthambisa, amayeza, izitshabalalisi, iikhemikhali, ukupakishwa kweemveliso zorhwebo.
