VMPET - yog hais txog zaj duab xis polyester aluminized. Siv rau zaj duab xis tiv thaiv ntawm cov khoom noj qhuav thiab puffed xws li biscuits thiab cov ntim sab nraud ntawm qee cov tshuaj thiab tshuaj pleev ib ce.

Cov yeeb yaj kiab aluminized muaj ob qho tib si yam ntxwv ntawm cov yeeb yaj kiab yas thiab cov yam ntxwv ntawm cov hlau. Lub luag haujlwm ntawm cov txhuas plating ntawm qhov chaw ntawm cov yeeb yaj kiab yog rau kev ntxoov ntxoo thiab tiv thaiv ultraviolet hluav taws xob, uas tsis yog tsuas yog ua kom lub neej txee ntawm cov ntsiab lus ntev dua, tab sis kuj txhim kho qhov ci ntawm cov yeeb yaj kiab. , daim ntawv thov ntawm cov yeeb yaj kiab aluminized hauv cov ntim khoom sib xyaw yog dav heev. Tam sim no, nws feem ntau yog siv rau hauv kev ntim khoom noj qhuav thiab puffed xws li biscuits, nrog rau kev ntim khoom sab nraud ntawm qee cov tshuaj thiab tshuaj pleev ib ce.

PET - tseem hu ua zaj duab xis polyester uas tiv taus kub heev. Nws muaj cov khoom zoo heev, cov khoom siv tshuaj lom neeg thiab kev ruaj khov ntawm qhov ntev, pob tshab, thiab kev siv rov qab tau, thiab tuaj yeem siv dav hauv kev kaw suab sib nqus, cov ntaub ntawv photosensitive, khoom siv hluav taws xob, rwb thaiv hluav taws xob, zaj duab xis kev lag luam, kho kom zoo nkauj ntim khoom, tiv thaiv kev tshuaj ntsuam, iav kho qhov muag tiv thaiv qhov chaw thiab lwm yam teb. Zaj duab xis polyester uas tiv taus kub heev: FBDW (ib sab matte dub) FBSW (ob sab matte dub) Cov lus qhia txog zaj duab xis polyester uas tiv taus kub heev Thickness dav dov txoj kab uas hla 38μm ~ 250μm 500 ~ 1080mm 300mm ~ 650mm 76mm (3〞), 152mm (6〞) Lus Cim: Cov lus qhia dav tuaj yeem tsim tau raws li qhov xav tau tiag tiag. Qhov ntev ntawm zaj duab xis yob yog 3000m lossis 6000 sib npaug rau 25μm.

PE-LLD—Linear Low Density Polyethylene (LLDPE), tsis muaj tshuaj lom, tsis muaj saj, tsis muaj ntxhiab, dawb mis nyuj nrog qhov ceev ntawm 0.918 ~ 0.935g / cm3. Piv nrog LDPE, nws muaj qhov kub thiab txias dua thiab kub yaj, thiab muaj qhov zoo ntawm lub zog siab, kev tawv zoo, kev ruaj khov siab, kev tiv taus kub, thiab kev tiv taus txias. Nws kuj muaj kev tiv taus kev tawg ntawm kev ntxhov siab ib puag ncig, lub zog cuam tshuam, thiab kev ruaj khov. Lub zog rhuav thiab lwm yam khoom, thiab tuaj yeem tiv taus cov kua qaub, alkalis, cov kuab tshuaj organic, thiab lwm yam thiab siv dav hauv kev lag luam, kev ua liaj ua teb, tshuaj, kev tu cev thiab cov khoom siv niaj hnub. Cov polyethylene linear low-density polyethylene (LLDPE) resin, hu ua polyethylene tiam thib peb, muaj lub zog tensile, lub zog rhuav, kev ntxhov siab ib puag ncig, kev tiv taus kub qis, thiab kev tiv taus kub thiab tho qhov tshwj xeeb tshaj yog.

BOPA (NYLON) - yog lus Askiv luv luv ntawm Biaxially oriented polyamide (nylon) zaj duab xis. Biaxially oriented nylon zaj duab xis (BOPA) yog ib yam khoom tseem ceeb rau kev tsim ntau yam khoom ntim khoom sib xyaw, thiab tau dhau los ua cov khoom ntim khoom loj thib peb tom qab BOPP thiab BOPET zaj duab xis.

Zaj duab xis Nylon (tseem hu ua PA) Zaj duab xis Nylon yog ib zaj duab xis tawv heev nrog kev pom tseeb zoo, ci ntsa iab zoo, lub zog tensile siab thiab lub zog tensile, thiab zoo tiv taus kub, txias thiab roj tsis kam. Zoo tiv taus cov kuab tshuaj organic, tiv taus kev sib txhuam, tiv taus qhov tho, thiab mos mos, zoo tiv taus oxygen, tab sis tsis zoo thaiv dej pa, nqus dej noo ntau, noo noo permeability, tsis zoo kaw cua sov, tsim nyog rau ntim cov khoom tawv, xws li cov zaub mov roj, cov khoom nqaij, cov zaub mov kib, cov zaub mov ntim hauv lub tshuab nqus tsev, cov zaub mov steamed, thiab lwm yam.

Peb cov yeeb yaj kiab thiab cov laminates tsim ib txheej rwb thaiv tsev uas tiv thaiv koj cov khoom kom tsis txhob puas thaum ntim khoom tas. Ntau hom khoom ntim khoom xws li polyethylene, polyester, nylon, thiab lwm yam uas teev hauv qab no yog siv los tsim cov laminate barrier no.
