Tus Qauv Ntawm Cov Khoom Noj Tsiaj Ntim

Txheej txheej (Printing / Abrasion-cov txheej txheem): Feem ntau PET (polyester) lossis BOPP; muab cov ntawv luam tawm zoo heev, tiv thaiv kev puas tsuaj, thiab puncture tsis kam, thaum tiv thaiv tus cwj mem thiab tswj lub pob qhov zoo li.
Intermediate Layer (Barrier Layer): Ib txheej tseem ceeb ua haujlwm; Feem ntau siv AL (txhuas ntawv ci rau kev ua haujlwm siab tshaj plaws), VMPET (metallized PET rau nruab nrab barrier kev ua tau zoo), los yog NY (nylon rau txhim kho toughness / puncture resistance) los thaiv cov pa oxygen, lub teeb, thiab noo noo, yog li tiv thaiv oxidation thiab lwj ntawm cov roj thiab roj.
Txheej sab hauv (Tshav kub- sealing/Safety Layer): Feem ntau PE (polyethylene), CPP (cam khwb cia polypropylene), los yog EVOH; los rau hauv kev sib cuag ncaj qha nrog cov zaub mov, yuav tsum ua tau raws li cov zaub mov- qib kev nyab xeeb cov qauv, thiab muab cov cua kub zoo heev- foob lub zog thiab ya raws.
