Nyob rau hauv kev lag luam ntim niaj hnub, ntim khoom siv tau siv nyob rau hauv cov zaub mov, tshuaj, thiab siv tshuaj txhua hnub, thiab tus nqi {{{- ua hauj lwm ua tau zoo. Txawm li cas los xij, cov kev xaiv ntawm cov khoom cuam tshuam ncaj qha cuam tshuam rau kev ua haujlwm, kev nyab xeeb, thiab ib puag ncig kev ua tau zoo ntawm kev tshawb fawb txog kev tshawb fawb.
Kev ua haujlwm yog qhov tseem ceeb
Cov ntaub ntawv ntim ntim yuav tsum ua kom tau raws li cov cai tiv thaiv kev tiv thaiv cov ntsiab lus. Piv txwv li, polyethylene (PE) lossis polypropylene (PP) feem ntau siv rau cov khoom noj khoom haus ntim khoom thiab cov tshuaj lom neeg ua kom zoo nkauj thiab cov pa oxygen. Rau cov khoom lag luam zoo siab yuav tsum tau ua, xws li nqaij lossis kas fes, ua kom muaj kuab lom cophyl (EVOH)
Kev nyab xeeb thiab kev tswj hwm ua haujlwm yog qhov tseem ceeb.
Cov ntaub ntawv yuav tsum ua kom muaj raws li cov qauv kev nyab xeeb rau kev nyab xeeb, xws li muaj ntawv pov thawj los ntawm Asmeskas Chaw Tswj Khoom Noj thiab Tshuaj (FDA) lossis European Union's EFSA. Piv txwv li, ntim uas los rau hauv kev sib chwv nrog cov zaub mov yuav tsum zam tau PVC muaj cov hnab yas thiab tsis xaiv cov tsiaj ntawv nyab xeeb lossis bio- raws cov ntaub ntawv. Tsis tas li ntawd, cov chaw ntim cov tshuaj yuav tsum tau xav txog lub teeb kev tiv thaiv thiab tsis muaj steriliation companibility. Piv txwv li, tus tsiaj / al / pe tus qauv muaj ob lub teeb {{6} bealing thiab airtight ntsaws ruaj ruaj.
Environmental Hloov Tsav Tsav Tsheb tshiab
Nrog rau cov muaj koob meej loj hlob ntawm kev txhim kho cov ntsiab lus, biodegradable cov ntaub ntawv xws li polylactic acid (PLA) thiab biodegradable PE tau txais cov koob npe nrov. Txawm hais tias lawv cov nqi siab dua, lawv tau dhau los ua ib qho kev xaiv tseem ceeb hauv cheeb tsam nrog txoj cai nruj ib puag ncig, xws li EU. At the same time, single-material packaging (such as all-PE structures) is gradually replacing traditional multi-layer composite films due to its ease of recycling.
Hauv cov ntsiab lus, kev xaiv ntawm cov ntaub ntawv ntim yooj ywm yuav tsum muaj kev sib npaug ntawm kev tiv thaiv kev ua haujlwm, kev nyab xeeb, thiab ib puag ncig kev tiv thaiv. Cov tuam txhab yuav tsum siv cov txheej txheem xws li cov khoom siv mus ncig ua si hauv lub hom phiaj kev tswj hwm uas yuav tsum muaj cov kev tswj hwm tau zoo uas sib xyaw ua lag luam nrog lub luag haujlwm.
