Qhov zoo tshaj ntawm qhov sawv ntsug- lub hnab ntim khoom yog tsim los ntawm nws cov khoom siv. Peb MOPP / VMPET / PE laminate sawv cev rau qhov tseem ceeb ntawm cov khoom siv tshawb fawb, tsim kom tau raws li qhov xav tau ntawm cov khoom ntim niaj hnub no. Txhua txheej tau raug xaiv zoo thiab sib xyaw ua ke los tsim cov qauv kev sib koom ua ke uas muaj qhov zoo sib npaug ntawm qhov tawv, kev tiv thaiv, sealing kev ntseeg tau, thiab kev zoo nkauj zoo nkauj, xa cov kev ua tau zoo uas tsis tuaj yeem sib tw.
Lub MOPP (Metalized Oriented Polypropylene) txheej txheej tsim lub hnab zoo nkauj sab nrauv. Tshaj nws qhov siab -gloss metallic tiav uas muab cov txee tshwj xeeb thiab cov duab pom tseeb, nws ua haujlwm tseem ceeb tiv thaiv cov pa ya raws. Qhov no yog ib qho tseem ceeb rau cov khoom uas yuav tsum khaws crispness los yog tiv thaiv clumping. Nws qhov kev ruaj ntseg ntawm qhov nruab nrab thiab lub zog tensile muab lub hnab nrog qhov tsim nyog "sawv-nce" rigidity thiab tsis kam rau tearing thaum tuav thiab kev thauj mus los.
Nyob rau hauv lub plawv ntawm cov qauv lus yog VMPET (Nqus Metalized Polyethylene Terephthalate) txheej. Cov yeeb yaj kiab no yog qhov tseem ceeb rau lub hnab ntim khoom ua haujlwm. Los ntawm cov txheej txheem nqus hlau metallization, nws ua tiav qhov tshwj xeeb ntawm cov roj barrier, txo qis oxygen xa mus (OTR). Qhov no txuas ntxiv lub neej txee ntawm cov khoom raug oxidation, xws li roj, txiv ntseej, thiab cov nqaij ua tiav. Nyob rau tib lub sijhawm, qhov metallized nto ua lub teeb pom kev zoo, tiv thaiv lub teeb - cov ntsiab lus rhiab zoo li cov vitamins lossis qee yam txuj lom los ntawm degradation. VMPET kuj tseem txhim kho tag nrho cov puncture thiab abrasion tsis kam ntawm laminate.
Thaum kawg, PE (Polyethylene) innermost txheej yog lub workhorse ntawm sealability thiab khoom ruaj ntseg. Cov zaub mov no - qib zaj duab xis kom ntseeg tau tias muaj zog, zoo ib yam, thiab hermetic thaum tshav kub kub seals uas yog ib qho tseem ceeb rau kev tswj cov khoom tshiab thiab tiv thaiv kom tsis txhob xau. Nws yooj yim ua kom lub hnab tuaj yeem tiv taus qhov kev ntxhov siab ntawm kev ntim khoom, kev xa khoom, thiab kev siv txhua hnub. Tsis tas li ntawd, nws cov tshuaj tiv thaiv zoo heev ua rau nws tsim nyog rau ntau yam khoom, los ntawm cov khoom qhuav thiab hmoov mus rau cov ntsiab lus nruj dua li cov zaub mov tsiaj lossis qee yam tshuaj. Ua ke, qhov tri- txheej txheej architecture tsim muaj kev tiv thaiv, ruaj khov, thiab pom qhov pom kev zoo tshaj plaws rau daim ntawv thov hwm.
