Cov khoom siv ntawm cov txheej txheem sib xyaw ua ke yog cov khoom siv ntau polyethylene (PE), nylon (NY), txhuas (AL), nrum polypropylene zaj duab xis (CPP zaj duab xis), thiab siv cov ntaub ntawv PE raw tuaj yeem ua rau luam ntawv zoo. thiab tsis thim, siv cov khoom NY. Cov pa oxygen permeability ntawm lub pob tuaj yeem raug txo kom tsawg. Kev siv ntawm AL txhuas hlau yog qhov tseem ceeb los tiv thaiv lub teeb thiab lub teeb kub. Qhov innermost ib qho yog cpp zaj duab xis, ua noj qib qeb CPP (Retort CPP, RCPP rau luv luv), thiab LLDPE, LDPE, HDPE, PET, piv rau lwm cov yeeb yaj kiab xws li PVG, tus nqi qis dua thiab cov zis siab dua. Nws yog stiffer tshaj PE zaj duab xis. Cov dej noo zoo tshaj thiab tsw ntxhiab tsw qab. Versatile, tuaj yeem siv los ua cov yeeb yaj kiab puag txheej rau cov khoom siv sib xyaw. Metallization tuaj yeem ua tau. Raws li cov zaub mov ntim khoom lag luam thiab ntim khoom, nws muaj cov yam ntxwv ua tau zoo tshaj plaws, kom cov khoom lag luam tseem pom meej meej hauv qab ntim ntawv. Cov khoom siv sib txawv no ua ke hauv cov qib hluav taws xob kom ua tiav kev ntim khoom thiab sawv ruaj khov.
