tswm ciab lim rau BOPP zaj duab xis kab

Hauv kev tsim cov BOPP zaj duab xis, cov yaj ntawm siab molecular polypropylene yog thawj zaug ua rau hauv ib daim ntawv los yog tuab zaj duab xis los ntawm lub taub hau ntev thiab nqaim, thiab tom qab ntawd hauv lub tshuab stretching tshwj xeeb, ntawm qhov kub thiab txias, ib txhij los yog kauj ruam. los ntawm kauj ruam Cov zaj duab xis yog stretched nyob rau hauv ob txoj kev ntsug (longitudinal thiab transverse), thiab tom qab kom zoo cua txias los yog kev kho cua sov los yog ua tshwj xeeb (xws li corona, txheej, thiab lwm yam).

Feem ntau siv BOPP zaj duab xis muaj xws li: zoo tib yam biaxially oriented polypropylene zaj duab xis, tshav kub-sealable biaxially oriented polypropylene zaj duab xis, luam yeeb ntim zaj duab xis, biaxially oriented polypropylene pearlescent zaj duab xis, biaxially taw qhia polypropylene metallized zaj duab xis, matting zaj duab xis, thiab lwm yam.

BOPP zaj duab xis yog ib qho tseem ceeb ntawm cov khoom ntim khoom yooj yim. BOPP zaj duab xis tsis muaj xim, tsis muaj ntxhiab, tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab muaj lub zog tensile siab, cuam tshuam lub zog, rigidity, toughness thiab zoo transparency.

Lub zog saum npoo ntawm BOPP zaj duab xis yog tsawg, thiab kev kho corona yuav tsum tau ua ua ntej gluing lossis luam ntawv. Tom qab kev kho mob corona, BOPP zaj duab xis muaj kev hloov pauv tau zoo thiab tuaj yeem luam tawm kom tau txais qhov zoo nkauj, yog li nws feem ntau siv los ua cov txheej txheem txheej txheej ntawm cov yeeb yaj kiab sib xyaw.

Cov ntxaij lim dej yog ib feem tseem ceeb heev ntawm extruder, thiab tsuas yog cov khoom tsim nyog tuaj yeem tsim los ntawm cov ntxaij lim dej. Lub tshuab lim extruder yog siv rau kev pom thiab sib xyaw ntawm ntau yam khoom khov thiab cov khoom xws li yas, tshuaj fibers, roj hmab, kub yaj nplaum nplaum, nplaum nplaum, cov ntaub ntawv txheej, thiab cov khoom sib tov. Lub tshuab lim extruder muaj ib hom mesh. Nrog rau hom mesh siv, lub extruder tuaj yeem hloov cov ntxaij lim dej tsis cuam tshuam cov khoom los ntawm kev hloov pauv hloov pauv tsis siv neeg, txuag lub zog thiab lub sijhawm, cov khoom lag luam ruaj khov, paub txog kev hloov pauv tsis siv neeg lub vijtsam thiab kev ua haujlwm pub dawb, nce lub sijhawm pom zoo, thiab txo cov nqi tsim khoom. .
