BOPP Thiab PET zaj duab xis Taw qhia

Muaj ob yam khoom siv ntawm cov yeeb yaj kiab hauv kev lag luam laminated, BOPP thiab PET. Tom ntej no, cia peb saib qhov sib txawv ntawm ob qho no:

1. Cov khoom xyaw

BOPP Zaj Duab Xis: Ua los ntawm polypropylene, BOPP zaj duab xis tau dhau los ua cov txheej txheem biaxial orientation thaum lub sijhawm tsim khoom, txhim kho nws lub zog tensile, nruj, thiab pom qhov pom tseeb.

PET Zaj duab xis: Ua los ntawm polyethylene terephthalate, uas muaj lub zog tshwj xeeb ntawm kev siv tshuab, kev kub siab ua haujlwm, thiab cov khoom thaiv zoo heev.

2. Optical Properties

BOPP Zaj Duab Xis: Nws qhov tshwj xeeb meej meej thiab pob tshab, ua rau nws zoo tagnrho rau kev ntim khoom thiab daim ntawv sau npe uas xav tau kev pom zoo ntawm cov khoom.

PET Zaj duab xis: Kuj tseem muaj pob tshab nrog gloss zoo, tab sis PET zaj duab xis tej zaum yuav muaj xim daj me ntsis.

3. Kev tiv thaiv kub

BOPP Zaj duab xis: Cov cua kub zoo, nws tuaj yeem muag los yog deform ntawm qhov kub siab dua.

PET zaj duab xis: Tshwj xeeb kub tsis kam, nrog lub melting point ntau dua BOPP. Nws tuaj yeem tiv taus qhov kub thiab txias dua thiab tsim nyog rau kev ua kom tsis muaj menyuam thiab cov txheej txheem autoclaving.

Rau cov tshuab laminating, BOPP zaj duab xis yog cov yeeb yaj kiab yooj yim, thiab cov txheej txheem yooj yim ntawm cov cuab yeej yog rau BOPP, yog li kev sib cais tuaj yeem ua tiav siv rab riam ya los yog rab riam los yog xuab zeb. Txawm li cas los xij, PET zaj duab xis yuav tsum tau muab sib cais siv cov saw riam los yog riam kub vim nws cov tawv tawv heev.
