Tom qab kev saib xyuas ntawm BOPP cov yeeb yaj kiab, koj puas muaj qhov tsis txaus ntseeg ntawm cov khoom siv thoob plaws ntiaj teb no? Hauv qhov blog no, peb yuav nkag siab peb cov kev nkag siab rau nws qhov zoo thiab qhov tsis zoo, yog li zoo dua rau cov neeg siv khoom xav tau.
BOPP Film yog dab tsi
Biaxially Oriented Polypropylene (BOPP) zaj duab xis tau hloov pauv kev lag luam ntim khoom txij li nws tau nthuav tawm xyoo 1970s. Cov khoom siv tshiab no, ncab ob qho tib si mechanically thiab manually siv cov txheej txheem hla kev taw qhia, muaj kev sib xyaw tshwj xeeb ntawm cov khoom uas tau ua rau nws tseem ceeb hauv ntau yam kev siv.
Cov yam ntxwv tseem ceeb ntawm BOPP
Tsis muaj xim thiab tsw ntxhiab
Tsis muaj tshuaj lom muaj pes tsawg leeg
Balanced rigidity thiab toughness
Impressive cuam tshuam
siab Lub zog tensile (qhov tseem ceeb ntawm 130-300 MPa)
Exceptional pob tshab (txog 90% lub teeb kis tau tus mob)
Cov khoom no tau tso BOPP ua ntau yam khoom siv thoob plaws ntau qhov kev lag luam, los ntawm kev ntim khoom noj mus rau textile lamination.
Qhov zoo ntawm BOPP zaj duab xis
Lub cev muaj zog
BOPP ua tau zoo ntawm lub zog thiab ruaj khov, nrog lub zog tensile uas tuaj yeem ncav cuag li 300 MPa hauv lub tshuab kev taw qhia. Nws lub ntsej muag pom meej meej, nrog lub teeb kis tau tus nqi txog li 90%, txhim kho cov khoom pom ntawm lub khw muag khoom. Cov yeeb yaj kiab qhov kev ruaj ntseg kom ntseeg tau tias muaj kev ua tau zoo nyob hauv ntau daim ntawv thov, nrog rau cov nqi shrinkage qis dua 4% ntawm 130 ° C.
Kev tiv thaiv rau punctures thiab flex tawg ua rau BOPP zoo tagnrho rau kev tiv thaiv ntim. Piv txwv li, 20-micron BOPP zaj duab xis tuaj yeem tiv taus txog li 130 g / 25 μm hauv kev ntsuas kev cuam tshuam dart, ua kom pom tias nws muaj zog hauv kev siv tiag tiag hauv ntiaj teb.
Chemical Properties
BOPP ua raws li kev tiv thaiv tsis zoo tiv thaiv ya raws, muaj kuab paug, thiab tshuaj lom neeg. Nws cov dej vapor kis tus nqi (WVTR) tuaj yeem qis li 4-5 g / m² / hnub ntawm 38 ° C thiab 90% txheeb ze av noo, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom lag luam noo noo.
Cov yeeb yaj kiab roj thiab roj tsis kam, nrog cov txiaj ntsig zoo tshaj 7 ntawm cov khoom siv ntsuas ntsuas, ntxiv rau nws qhov kev siv tau. Cov khoom no ua rau BOPP qhov kev xaiv zoo tshaj plaws rau kev ntim khoom noj thiab kev siv hauv kev lag luam, qhov twg cov khoom tiv thaiv yog qhov tseem ceeb.
Environmental Benefits
Nyob rau hauv lub ntiaj teb niaj hnub no eco-conscious, BOPP ci nrog nws cov ntaub ntawv pov thawj ib puag ncig:
Recyclability : BOPP poob rau hauv kev rov ua dua code #5 (PP), ua rau nws rov ua dua tshiab.
Lub teeb yuag : Ib txwm ntom ntom ntawm 0.90-0.92 g / cm³ pab txo qis kev thauj mus los.
Kev tsim hluav taws xob ntau : Cov txheej txheem tsim khoom siv hluav taws xob tsawg dua piv rau lwm cov khoom siv.
Txoj kev tshawb fawb txog kev ua neej nyob ua los ntawm European Polypropylene Film Manufacturers Association pom tias BOPP cov yeeb yaj kiab muaj 40% qis dua cov pa roj carbon hneev taw piv rau cov yeeb yaj kiab sib npaug.
Economic zoo
BOPP muab cov txiaj ntsig tseem ceeb vim nws cov txiaj ntsig siab. Nws qhov ceev ntawm kwv yees li 0.90-0.92 g / cm³ ua rau ntau zaj duab xis ib chav tsev hnyav piv rau lwm txoj kev xws li polyester (density ~ 1.4 g / cm³). Qhov no txhais tau tias kev txuag nqi ntawm kev siv cov khoom siv thiab kev thauj mus los.
Kev lees paub thoob ntiaj teb ua kom yooj yim dua kev lag luam thoob ntiaj teb thiab xa khoom. Raws li kev lag luam cov ntaub ntawv qhia, thaj av Asia-Pacific tswj hwm lub lag luam BOPP, suav txog ntau dua 60% ntawm lub peev xwm tsim khoom thoob ntiaj teb.
