BOPET FILM yog dab tsi?
BOPET (Biaxially Oriented Polyethylene Terephthalate) zaj duab xis yog siab -polyester zaj duab xis stretched nyob rau hauv ob lub tshuab thiab transverse cov lus qhia. Cov txheej txheem biaxial orientation muab nws lub zog tensile zoo dua, zoo heev qhov ntev stability, thiab zoo heev optical clarity. Hauv kev ntim khoom, BOPET tau siv dav los ua cov txheej txheem luam ntawv zoo tshaj plaws lossis txheej txheej tseem ceeb hauv cov laminates, ua haujlwm rau zaub mov, dej haus, kev saib xyuas tus kheej, thiab kev lag luam. Tsis zoo li tus tsiaj tsis yog-oriented PET, BOPET yog qhov tawv, muaj zog dua, thiab tswj kev ruaj ntseg nyob rau hauv siab - cov txheej txheem kub xws li luam ntawv thiab retorting yam tsis muaj shrinking. Nws muaj nyob rau hauv cov khoom siv lead ua-cov qhab nia ntshiab rau gloss thiab pob tshab, nrog rau hauv metallized los yog coated variants uas muab tshwj xeeb oxygen thiab noo noo barrier zog.
