Biaxially oriented polypropylene (BOPP) zaj duab xis tau dhau los ua cov yeeb yaj kiab loj hlob hauv ntiaj teb kev lag luam vim nws qhov tshwj xeeb ua ke ntawm cov khoom xws li zoo dua shrinkage, nruj, clarity, sealing, torsion tuav thiab barrier zog.
BOPP zaj duab xis yog siv rau ntau yam kev siv, suav nrog:
Kev ntim khoom yooj yim
siab rhiab daim kab xev
Printing thiab Lamination
nyob ruaj ruaj
Metalization
paj lub tes tsho
Cable qhwv thiab rwb thaiv tsev
Raws li cov cob qhia tshwj xeeb molecular qauv thiab kev ruaj ntseg, cov homopolymers muaj cov khoom siv kho qhov muag thiab kho qhov muag, nrog rau kev ua haujlwm zoo heev.
Nws lub siab clarity thiab tsis tshua muaj cua daj cua dub pab cov neeg tsim yeeb yaj kiab lossis cov neeg ntim khoom tsim cov yeeb yaj kiab glossy, high-clarity uas txhim kho cov tsos ntawm ntim lossis lwm yam khoom.
Tsis tas li ntawd, txawm tias nyob rau hauv qis sealing pressures thiab tom qab kev kho deg los tiv thaiv ingress ntawm ya raws thiab kab mob.Vim muaj qhov sib npaug ntawm cov qauv polymer, cov polymer kuj muaj qhov siab melting point rau kev ua haujlwm yooj yim nrog rau qhov kub thiab txias pib thiab lub qhov rais dav.
Lwm cov txiaj ntsig suav nrog:
Yooj yim rau ncab kom nrawm thiab du ua haujlwm ntawm kev kub ceev FFS (daim ntawv, sau thiab foob) lossis lwm lub tshuab
Tsawg tack thiab yooj yim lub puab tsaig tso tawm kom zoo runnability ntawm ntim tshuab
Tsawg amorphous feem ua rau qis xylene extractables
Tsawg tawg ntawm amorphous thiab qis Mw (molecular hnyav) Cheebtsam thiab additives, muab cov khoom ruaj khov
Tsawg txav ntawm cov yeeb yaj kiab metallized
