• Khoom siv hluav taws xob thiab cov khoom siv hauv kev lag luam uas rhiab rau dej noo

Cov yeeb yaj kiab uas muaj teeb meem siab sib piv li cas nrog cov yeeb yaj kiab txheem?

Cov yeeb yaj kiab sib xyaw ua ke tej zaum yuav muab kev tiv thaiv yooj yim tab sis tsis haum rau cov khoom uas xav tau kev khaws cia ntev.
Cov yeeb yaj kiab thaiv siab muaj cov txheej tshwj xeeb xws li ntawv ci txhuas, EVOH, lossis PET hlau kom txo tau cov roj thiab dej noo (OTR thiab MVTR).
Lawv ua kom muaj kev tiv thaiv khoom zoo dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw khaws cia lossis kev thauj mus los hnyav.

Cov yeeb yaj kiab thaiv siab puas tsim nyog rau kev ntim khoom nqus tsev thiab MAP?

Yog lawm, cov yeeb yaj kiab sib xyaw ua ke uas muaj kev thaiv siab feem ntau siv rau hauv cov hnab nqus tsev thiab cov ntim khoom hloov kho huab cua (MAP).
Lawv qhov kev nkag mus tsawg pab tshem tawm cov pa oxygen thiab khaws cov nitrogen lossis CO₂, ua kom tshiab thiab tiv thaiv cov kab mob loj hlob.
Lawv siv dav hauv kev ua nqaij, ntim cheese, thiab cov khoom noj uas npaj txhij noj.

Cov yeeb yaj kiab thaiv siab puas tuaj yeem kaw, luam tawm, lossis kho kom haum?

Muaj tseeb tiag. Cov yeeb yaj kiab no tuaj yeem kaw tau los ntawm cua sov lossis kaw tau txias, nyob ntawm seb cov txheej kaw (PE, CPP, EVA, thiab lwm yam).
Lawv sib xws nrog gravure, flexo, thiab digital printing.
Cov yam ntxwv xaiv tau suav nrog cov notches yooj yim rhuav, cov zippers rov kaw tau, txheej tiv thaiv pos huab, thiab laser scoring.
Qhov tuab, qib thaiv, thiab kev kho saum npoo tuaj yeem hloov kho raws li cov kev xav tau ntim khoom tshwj xeeb.

Cov yeeb yaj kiab no puas muaj kev nyab xeeb rau zaub mov thiab ua raws li cov cai?

Yog, cov yeeb yaj kiab sib xyaw ua ke uas ua los ntawm cov khoom noj khoom haus zoo yog tsim los raws li cov qauv FDA, EU, thiab GB.
Lawv muaj kev nyab xeeb rau kev sib cuag ncaj qha nrog cov khoom noj thiab dej haus, suav nrog cov khoom khov, cov khoom siv hauv lub tub yees, thiab cov ntawv thov uas siv tau dua.
Daim ntawv pov thawj ntawm kev tshuaj xyuas (COA), cov ntawv qhia txog kev hloov chaw, thiab cov ntaub ntawv khoom siv tuaj yeem muab tau thaum thov.

Muaj cov thicknesses twg rau cov yeeb yaj kiab thaiv siab?

Feem ntau qhov tuab ntawm 50 microns txog 180 microns nyob ntawm seb cov qauv thiab kev siv.
Cov zaj duab xis nqus tsev feem ntau yog 70–150 microns, thaum cov khoom noj txom ncauj laminates tej zaum yuav nyias dua (20–60 microns).
Cov qauv tsim tshwj xeeb tuaj yeem tsim raws li kev rhiab heev ntawm cov khoom thiab cov kev xav tau ntawm kev tuav tshuab.

Cov yeeb yaj kiab uas muaj kev thaiv siab puas yog cov khoom siv rov ua dua tshiab lossis zoo rau ib puag ncig?

Cov yeeb yaj kiab tiv thaiv ib txwm muaj ntau yam khoom siv nyuaj rau rov ua dua tshiab.
Txawm li cas los xij, cov yeeb yaj kiab tiv thaiv ib yam khoom siv rov ua dua tshiab (piv txwv li, tag nrho-PE lossis tag nrho-PP) muaj ntau zuj zus, muab cov kev daws teeb meem ntim khoom ruaj khov.
Qee lub tuam txhab tsim khoom kuj muab cov yeeb yaj kiab tiv thaiv bio-based siv cov khoom siv compostable xws li PLA lossis cellulose.
Nws yog ib qho tseem ceeb kom phim cov kev xav tau kev ua tau zoo nrog cov hom phiaj kev ruaj khov thaum xaiv cov yeeb yaj kiab.
