Hom yas zaj duab xis

PVA coated high barrier zaj duab xis

Nqe kev ua tau zoo piv ntawm cov yas zaj duab xis

PVA coated high barrier zaj duab xis yog luam tawm thiab compounded los ntawm txheej PVA nrog nano inorganic tshuaj ntawm polyethylene zaj duab xis. Yog tias tsis muaj tus nqi nce ntxiv, nws qhov kev ua tau zoo tsis yog tsuas yog zoo dua li EVOH tsib txheej co extruded zaj duab xis, tab sis kuj yog tus nqi ntim tau txo qis, uas tuaj yeem tsis tsuas yog xyuas kom txhua qhov kev xav tau zoo rau kev ntim aseptic ntawm cov khoom ntim, tab sis kuj. txo tus nqi ntawm aseptic ntim rau cov lag luam ua zaub mov, Nws tuaj yeem siv los ntim cov dej qab zib, kua txiv hmab txiv ntoo, mis nyuj, kua ntses thiab vinegar.

Biaxially taw qhia polypropylene zaj duab xis (BOPP)

Biaxially oriented polypropylene zaj duab xis yog tsim los ntawm co extruding polypropylene hais rau hauv nplooj ntawv, thiab ces ncab nyob rau hauv ob qho tib si ntsug thiab kab rov tav cov lus qhia. Vim lub tensile molecular orientation, cov yeeb yaj kiab zoo li no muaj lub cev ruaj khov zoo, lub zog siv zog, huab cua nruj, siab transparency thiab glossiness, thiab yog tawv thiab hnav-resistant. Nws yog feem ntau siv tshuab luam ntawv nrog lub thickness ntawm 20-40 μ m. Feem ntau siv yog 20 μm. Lub ntsiab tsis zoo ntawm biaxially oriented polypropylene zaj duab xis yog nws cov khoom tsis zoo thaum tshav kub kub sealing. Yog li ntawd, nws feem ntau yog siv los ua cov yeeb yaj kiab sab nrauv ntawm cov yeeb yaj kiab sib xyaw. Piv txwv li, cov khoom pov thawj noo noo, pob tshab, lub zog, nruj thiab luam tawm ntawm cov ntaub ntawv sib xyaw nrog polyethylene zaj duab xis yog qhov zoo tagnrho, thiab nws yog qhov tsim nyog rau cov khoom noj qhuav. Raws li qhov saum npoo ntawm biaxially oriented polypropylene zaj duab xis yog tsis-polar, nrog crystallinity siab thiab tsis tshua muaj lub zog tsis muaj zog, nws cov ntawv luam tawm tsis zoo, thiab nws cov adhesion rau number case thiab nplaum tsis zoo, yog li kev kho saum npoo yuav tsum tau ua ntej luam ntawv thiab laminating.

Low-density polyethylene zaj duab xis (LDPE)

Tsawg ntom polyethylene zaj duab xis feem ntau yog tsim los ntawm tshuab moulding thiab daim kab xev casting. Lub thickness ntawm cam khwb cia polyethylene zaj duab xis yog ib yam, tab sis vim nws cov nqi siab thiab tus nqi qis, nws yog dav siv. Low density polyethylene (LDPE) zaj duab xis yog ib qho translucent, ci iab, mos zaj duab xis nrog cov tshuaj lom neeg ruaj khov, kub sealing, dej tsis kam, dej tsis kam, khov tsis kam thiab kub kub. Nws qhov tsis zoo yog qhov tsis zoo ntawm cov pa oxygen, uas feem ntau yog siv rau hauv cov yeeb yaj kiab sab hauv ntawm cov khoom ntim khoom sib xyaw ua ke. Nws tseem yog qhov siv ntau tshaj plaws thiab feem ntau siv cov yas ntim zaj duab xis, suav txog ntau dua 40 feem pua ​​​​ntawm kev noj cov yas ntim zaj duab xis.

Vim hais tias polyethylene molecule tsis muaj pawg polar, thiab muaj crystallinity siab thiab tsis tshua muaj lub zog tsis muaj zog, kev luam ntawv ntawm cov yeeb yaj kiab yog qhov tsis zoo, thiab cov adhesion rau number case thiab nplaum yog qhov tsis zoo, yog li kev kho deg yuav tsum tau ua ntej luam ntawv thiab sib xyaw.

Polyester zaj duab xis (PET)

Polyester zaj duab xis yog ua los ntawm polyethylene terephthalate li raw khoom, uas yog extruded rau hauv cov nplooj ntawv tuab thiab ces biaxially stretched. Nws yog xim tsis muaj xim, pob tshab thiab glossy zaj duab xis nrog cov khoom siv zoo heev, siab rigidity, hardness thiab toughness, puncture tsis kam, kev sib txhuam tsis kam, siab thiab kub tsis kam, tshuaj tsis haum, roj tsis kam, huab cua nruj thiab tshuaj tsw qab. Nws yog ib qho ntawm feem ntau siv barrier composite film substrates. Txawm li cas los xij, tus nqi ntawm polyester zaj duab xis yog qhov siab, thiab dav dav yog 12 μ m. Nws feem ntau yog siv los ua cov khoom siv sab nrauv ntawm kev ntim khoom noj, nrog kev luam ntawv zoo.
