•Peb nyiam hu cov hnab yas ntim khoom sib xyaw ua ke.

•Txhais tau hais tias, nws txhais tau tias cov ntaub ntawv zaj duab xis ntawm cov khoom sib txawv tau sib txuas ua ke thiab sib xyaw ua ke los ua lub luag haujlwm ntawm kev nqa, tiv thaiv thiab kho kom zoo nkauj.

•Lub hnab ntim khoom sib xyaw ua ke txhais tau tias yog ib txheej ntawm cov khoom sib txawv ua ke.

•Cov txheej tseem ceeb ntawm cov hnab ntim khoom feem ntau yog sib txawv los ntawm txheej sab nraud, txheej nruab nrab, txheej sab hauv, thiab txheej nplaum. Lawv tau muab tso ua ke rau hauv ntau kab raws li cov qauv sib txawv.

•Cia YPAK piav qhia cov txheej txheem no rau koj:

•1. Cov txheej sab nraud tshaj plaws, tseem hu ua txheej luam ntawv thiab txheej puag, xav tau cov ntaub ntawv uas muaj kev ua tau zoo ntawm kev luam ntawv thiab cov khoom siv kho qhov muag zoo, thiab tau kawg zoo tiv taus cua sov thiab lub zog kho tshuab, xws li BOPP (ncab polypropylene), BOPET, BOPA, MT, KOP, KPET, polyester (PET), nylon (NY), ntawv thiab lwm yam ntaub ntawv.

•2. Txheej nruab nrab kuj hu ua txheej thaiv. Txheej no feem ntau siv los txhawb kom muaj qee yam ntxwv ntawm cov qauv sib xyaw. Nws yuav tsum muaj cov khoom thaiv zoo thiab muaj zog tiv thaiv dej noo zoo. Tam sim no, cov uas siv ntau dua hauv khw yog cov ntawv ci txhuas (AL) thiab zaj duab xis txhuas (VMCPP). , VMPET), polyester (PET), nylon (NY), zaj duab xis polyvinylidene chloride (KBOPP, KPET, KONY), EV, thiab lwm yam.

•3. Txheej thib peb kuj yog cov khoom siv txheej sab hauv, tseem hu ua txheej kaw cua sov. Cov qauv sab hauv feem ntau yog sib cuag ncaj qha nrog cov khoom, yog li cov khoom siv xav tau kev hloov pauv, kev tiv thaiv permeability, kev kaw cua sov zoo, pob tshab, qhib tau thiab lwm yam haujlwm.

•Yog tias nws yog cov khoom noj uas ntim rau hauv lub hnab, nws kuj yuav tsum tsis muaj tshuaj lom, tsis muaj saj, tiv taus dej, thiab tiv taus roj. Cov ntaub ntawv siv feem ntau suav nrog LDPE, LLDPE, MLLDPE, CPP, VMCPP, EVA (ethylene-vinyl acetate copolymer), EAA, E-MAA, EMA, EBA, Polyethylene (PE) thiab nws cov ntaub ntawv hloov kho, thiab lwm yam.
