BOPP luam yeeb ntim zaj duab xis, tseem hu ua biaxially oriented polypropylene luam yeeb zaj duab xis, abbreviated li luam yeeb zaj duab xis, yog tsim los ntawm coextruding thiab stretching ntau yam functional polypropylene ntaub ntawv. Tam sim no, cov tuam txhab lag luam hauv tsev feem ntau siv peb txheej (A / B / C) coextrusion tshuab los tsim cov yeeb yaj kiab BOPP cov yeeb yaj kiab ua tau zoo los ntawm kev sib tw biaxial. Nws muaj cov pob tshab thiab glossiness, cov khoom tsis muaj tshuaj lom, cov qauv molecular ruaj khov, thiab qee yam khoom thaiv kev tiv thaiv cov ntxhiab thiab noo noo, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev ntim luam yeeb.
BOPP luam yeeb ntim zaj duab xis feem ntau muab faib ua cov cua sov shrinkable hom thiab hom zoo tib yam:
- Thaum tshav kub kub shrinkable hom luam yeeb ntim zaj duab xis: Vim nws cov thermal shrinkage tus nqi siab dua, feem ntau ntau dua 7%, tshav kub shrinkable zaj duab xis tuaj yeem nruj thiab uniformly qhwv cov ntawv luam yeeb tom qab ntim, kom lub sij hawm ntev nruj tsis loosening. Nws cov yam ntxwv tseem ceeb suav nrog kev ntim khoom zoo ntawm lub cev, kov yeej qhov teeb meem ntawm kev so thiab wrinkles hauv ntim zaj duab xis rau lub thawv ntim nyuaj, thiab vim yog siv cov cuab yeej tshwj xeeb ua, nws muaj qhov kub thiab txias shrinkability, siab transparency, glossiness, thiab zoo dua high-speed ntim kev ua tau zoo.
- Hom luam yeeb ntim zaj duab xis: Ib hom luam yeeb yeeb yaj kiab feem ntau muaj qhov ua haujlwm me me thaum tshav kub kub ua haujlwm, nrog tus nqi shrinkage feem ntau tswj ntawm (2%-5}%), feem ntau yog siv rau cov thawv me me thiab cov khoom ntim.
Cov yam ntxwv ntawm BOPP luam yeeb ntim zaj duab xis:
- BOPP zaj duab xis muaj cov khoom siv kho qhov muag zoo heev.
- Tsawg haze, uas tsis yog xim dawb tuaj yeem cuam tshuam qhov ci ntawm lub thawv luam yeeb xim.
- Zoo tshav kub shrinkability tuaj yeem muab cov khoom ntim ntim ntim.
- Kev tsim tshwj xeeb tsim kev sib txawv ntawm qhov ua tau zoo ntawm qhov chaw sab hauv ntawm zaj duab xis yog tshwj xeeb tshaj yog haum rau lub cev ntim khoom.
- Lub tshuab adaptability zoo heev, muaj peev xwm ua kom haum rau ntau lub thawv ntim tshuab luam yeeb rau ntim ceev.
- Tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab muaj lub zog tensile siab, cuam tshuam lub zog, rigidity, toughness, thiab zoo pob tshab.
