Ku hava swilo swo paka hi swoxe leswi tiyisisaka vutomi byo karhi bya xelufu. PVC/PE/PVDC yinga hunguta kutsakama xikan’we naku hlangana na oxygen, kambe nkarhi wo hela wufanele ku simekiwa hiku tirhisa nongonoko wa ku tshamiseka lowu tiyisisiweke wa muendli wa mirhi hiku tirhisa sisiteme yo paka leyi heleleke.
Ina. Vaxavi vafanele ku kambela thermoforming, khwalithi ya cavity, ku pfariwa, matirhelo ya roll, interlayer adhesion xikan’we na swilaveko swa barrier leswi faneleke eka layini yo paka leyi kunguhatiweke loko vanga se pfumelela vuhumelerisi bya xitalo.
PVC/PE/PVDC triplex film yina nkoka hikuva yi hlanganisa mintirho yinharhu yohambana: PVC yinyika nseketelo wa thermoforming, PE yi hoxa xandla eka ku cinca cinca na matirhelo ya processing, naswona PVDC yinyika xisirhelelo xa ndzhongho na oxygen yosungula.
Xivumbeko lexinene xa ku paka mirhi hikwalaho xi fanele ku hlawuriwa eka swilaveko leswi pimiwaka ku tlula marito yo fana na 'TOP-grade' kumbe 'maximum barrier.'
Nyika Wallis WVTR ya wena leyi kongomisiweke na OTR, ku enta hinkwako, ntiko wa PVDC coating, ku dirowa ka cavity, modele ya blister-machine, lidding foil, ku anama ka roll, makete wa laha u yaka kona na nhlayo leyi languteriweke ku burisana hi tisampulu leti faneleke na vuhumelerisi lebyi endleriweke wena.
