PVA-Coated High-Barrier Film
PVA-coated siab- zaj duab xis barrier yog tsim los ntawm txheej txheej polyethylene zaj duab xis nrog PVA (hloov nrog nano-inorganic additives) thiab tom qab ntawd muab nws rau cov txheej txheem luam ntawv thiab lamination. Yog tias tsis muaj tus nqi nce ntxiv, nws txoj kev ua haujlwm tsis zoo yog qhov zoo tshaj plaws ntawm tsib- txheej co-extruded EVOH zaj duab xis, thaum cov nqi ntim tau txo qis. Qhov no tsis tsuas yog ua kom ntseeg tau tias cov khoom ntim tau raws li txhua qhov kev xav tau zoo rau kev ntim aseptic tab sis kuj txo qis cov nqi ntim aseptic rau cov lag luam ua zaub mov; nws yog tsim rau ntim cov dej haus, kua txiv hmab txiv ntoo, mis nyuj, kua ntses, vinegar, thiab lwm yam.
Biaxially Oriented Polypropylene Zaj duab xis (BOPP)
Biaxially oriented polypropylene zaj duab xis yog tsim los ntawm co-extruding polypropylene granules rau hauv ib daim ntawv, uas yog ces stretched nyob rau hauv ob qho tib si longitudinal thiab transverse cov lus qhia.
Tsawg-Density Polyethylene Film (LDPE)
Tsawg-cov yeeb yaj kiab polyethylene feem ntau yog tsim los ntawm kev siv lub tshuab cua tshuab lossis cov txheej txheem cam khwb cia. Cam khwb cia polyethylene zaj duab xis muaj cov tuab tuab; vim nws cov nqi -kev ua tau zoo, nws yog hom siv dav tshaj plaws.
Polyester Zaj duab xis (PET)
Polyester zaj duab xis yog cov khoom siv los ntawm polyethylene terephthalate (PET) resin; ib daim ntawv tuab yog thawj zaug ntawm extrusion thiab ces biaxially stretched. Nws yog cov xim tsis muaj xim, pob tshab, thiab glossy zaj duab xis nrog cov khoom siv kho tshuab zoo heev - muaj cov yam ntxwv siab, hardness, thiab toughness, nrog rau kev tiv thaiv rau kev sib tsoo, tawg, thiab kub heev. Nws kuj nthuav tawm cov tshuaj lom neeg zoo thiab roj tsis kam, nrog rau cov pa roj zoo heev thiab cov ntxhiab tsw zoo - tuav cov khoom, ua rau nws muaj cov khoom siv sib xyaw rau cov yeeb yaj kiab sib xyaw.
Nylon zaj duab xis (PA)
Nylon zaj duab xis yog cov khoom tawv tawv heev, pob tshab, thiab glossy yam ntxwv los ntawm lub zog tensile siab. Nws muaj kev tiv thaiv zoo rau cov cua sov, txias, roj, thiab cov kuab tshuaj organic, nrog rau kev ua kom zoo zoo thiab ua haujlwm zoo. Txawm hais tias hloov tau yooj yim thiab muab cov pa oxygen zoo heev, nws muaj cov dej vapor barrier tsis zoo, nws yooj yim rau kev nqus dej thiab permeability, thiab muaj cua sov tsis zoo- muaj peev xwm sealing. Nws yog qhov tsim nyog rau ntim cov khoom nruj, xws li cov khoom noj muaj roj, cov khoom noj nqaij, cov khoom noj kib, lub tshuab nqus tsev -cov khoom ntim, thiab cov khoom noj rov qab.
Cast Polypropylene Zaj duab xis (CPP)
Cam khwb cia polypropylene zaj duab xis yog tsim los siv cov txheej txheem cam khwb cia thiab muaj nyob rau hauv ob lub ntsiab: dav -lub hom phiaj CPP thiab retort- qib CPP. Nws nta cov pob tshab zoo heev, cov tuab tuab, thiab cov khoom zoo ib yam hauv ob lub tshuab thiab cov lus qhia transverse; nws feem ntau yog siv los ua cov khoom siv sab hauv rau cov yeeb yaj kiab sib xyaw.
Aluminized Zaj duab xis
Feem ntau siv aluminized films yog aluminized polyester (VMPET) thiab aluminized CPP (VMCPP). Cov yeeb yaj kiab no muab cov yam ntxwv ntawm cov yeeb yaj kiab yas nrog cov hlau.
