Raws li kev tswj hwm ib puag ncig nruj thiab kev paub txog cov neeg siv khoom nce ntxiv, cov yeeb yaj kiab biodegradable tau txais lub zog raws li kev hloov pauv mus rau cov khoom siv niaj hnub. Txawm li cas los xij, cov lus nug txog lawv qhov kev ua tau zoo, kev ua raws cai, thiab kev siv nyiaj tau zoo tseem muaj ntau. Cov FAQ no hais txog kaum cov lus nug uas nquag nug los ntawm cov neeg ua haujlwm tshaj lij, muab kev pom tseeb ntawm cov ntaub ntawv tshawb fawb, daim ntawv thov, thiab cov qauv kev lag luam. Peb kuj tseem yuav kov ntawm cellophane - ib qho ntuj, biodegradable zaj duab xis uas ua rau rov qab los hauv eco-conscious ntim.
Dab tsi yog biodegradable films thiab yuav ua li cas lawv degrade?
Biodegradable filmsyog cov khoom uas tuaj yeem tawg los ntawm cov kab mob mus rau hauv dej, carbon dioxide, thiab biomass. Tsis zoo li cov yas yas, uas pheej niaj hnub mus ntau pua xyoo, cov ntaub ntawv no degrade ib txwm nyob rau hauv tej yam kev mob.
Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm "biodegradable" - degradation nyob rau hauv microbial kev ua si - thiab "compostable," uas yuav tsum tau tswj ib puag ncig (xws li, industrial composting) kom tiav kev tawg nyob rau hauv ib lub sij hawm teem tseg yam tsis muaj cov tshuaj lom residue.
Cov ntaub ntawv dab tsi yog siv rau hauv cov yeeb yaj kiab biodegradable thiab lawv txawv li cas?
Polylactic Acid (PLA)
Muab los ntawm pob kws los yog qab zib,PLA zaj duab xismuab zoo clarity thiab rigidity tab sis yog nkig, zoo liPLA zaj duab xis rau ntim khoom noj, thiab tsis haum rau kev siv high-flex. Industrial composting feem ntau yuav tsum tau ua kom zoo degradation.
Cellophane Zaj duab xis
Ua los ntawm regenerated cellulose (feem ntau yog ntoo pulp),cellophane zaj duab xisyog pob tshab, breathable, thiab biodegradable nyob rau hauv ob qho tib si industrial thiab ntuj ib puag ncig. Nws yog ib qho kev xaiv zoo tshaj plaws rau kev ntim khoom noj uas yuav tsum tau tswj cov dej noo. Txawm hais tias nws eco-friendliness, nws muaj ntau dua cov nqi tsim khoom thiab txwv cov cua sov sealability.
Raws li cov xwm txheej no ua rau cov yeeb yaj kiab degrade, thiab nws siv sijhawm ntev npaum li cas?
Biodegradable films degrade ntawm tus nqi sib txawv nyob ntawm seb cov khoom thiab ib puag ncig tej yam kev mob xws li kub, av noo, thiab microbial kev ua.
Polylactic Acid (PLA)
PLA cov yeeb yaj kiabyuav tsum muaj kev ua liaj ua teb ua liaj ua teb (kwv yees li 60 ° C, cov av noo siab) kom tag nrho degrade hauv 3-6 lub hlis. Nyob rau hauv tej yam ntuj tso av los yog hauv tsev compost ib puag ncig, degradation yog qeeb qeeb.
Cellophane
Cellophane films, ua los ntawm cov cellulose regenerated, feem ntau tawg nyob rau hauv 30-60 hnub nyob rau hauv tsev los yog industrial composting tej yam kev mob. Coated cellophane films yuav siv sij hawm txog 120 hnub vim muaj kev kho deg ntxiv.
Tswv yim: Nco ntsoov xyuas cov ntawv pov thawj zoo liTS EN 13432 or ASTM D 6400 Cov Lus Qhia Tshwj Xeeb, uas txheeb xyuas seb cov khoom puas yog compostable nyob rau hauv tej yam kev mob.
Yuav ua li cas biodegradable films piv rau cov tsoos plastics nyob rau hauv cov nqe lus ntawm tus nqi?
Cov yeeb yaj kiab biodegradable feem ntau kim dua li cov khoom siv xws li LDPE lossis PET. Txawm li cas los xij, lawv cov nqi mus sij hawm ntev nyob hauv:
Kev tswj hwm thiab se zoo
Hauv ntau thaj tsam, cov tuam txhab uas siv cov ntim khoom ruaj khov tuaj yeem tau txais txiaj ntsig los ntawm kev txhawb nqa se lossis zam kev nplua nyiaj ntsig txog kev txwv yas.
Tus nqi tag nrho ntawm kev muaj tswv cuab (TCO)
Txo cov nqi tu ib puag ncig, kev pov tseg yooj yim, thiab txhim kho cov khoom lag luam pom feem ntau offset tus nqi siab dua.
Cov neeg siv khoom nyiam
Eco-conscious cov neeg siv khoom muaj feem ntau yuav xaiv cov hom lag luam uas qhia tau tias muaj txiaj ntsig zoo los ntawm kev ntim khoom biodegradable.
Sij hawm dhau mus, raws li kev ntsuas ntau lawm thiab thev naus laus zis paub tab, tus nqi ntawm cov yeeb yaj kiab biodegradable yuav tsum txo qis.
Dab tsi yog cov kev siv ntawm biodegradable films?
Biodegradable films muaj ntau yam kev siv nyob rau hauv ntau yam sectors. Raws li YITO cov khoom lag luam, lawv feem ntau siv hauv:
Ntim Cov Khoom Noj

PLA cling films, PLA txiv hmab txiv ntoo & zaub hnab- Rauntim cov txiv hmab txiv ntoo thiab zaub, muab cov pob tshab zoo thiab tswj cov dej noo.
-
PLA shrink films, High-barrier PLA zaj duab xis- Haum rau cov khoom ci, khoom noj txom ncauj, khoom noj khoom haus, thiab lub raj mis labeling vim lawv sealability, clarity, thiab oxygen barrier zog.
Agricultural Films
-
PLA mulch films- Biodegradable films siv los npog cov av, txhim kho qhov kub thiab txias. Lawv ib txwm ua txhaum tom qab cov qoob loo, txo kev ua haujlwm rau kev tshem tawm.
Logistics thiab Industrial Ntim:
-
PLA stretch filmsthiabPLA shrink wraps- Muab cov ntim khoom ruaj ntseg rau kev thauj mus los thiab chaw cia khoom, nrog lub zog tensile zoo thiab yooj yim.
Khw muag khoom, khoom plig, thiab sau ntawv ntim:
-
Cellophane filmsthiab PLA zaj duab xis yog siv dav hauv kev qhwv khoom plig, txais tos daim npav tes tsho, thiab cigar ntim, zoo licigar cellophane qhwv. Lawv glossy tiav thiab breathability ua rau lawv zoo tagnrho rau cov khoom lag luam zoo tshaj plaws.
Txhua daim ntawv thov ua raws li cov kev xav tau ntim eco thiab tau txais kev pom zoo ntxiv los ua ib txoj hauv kev ruaj khov rau cov roj av-raws li plastics.
Dab tsi yog cov kev coj ua zoo tshaj plaws rau kev khaws cia thiab thauj cov yeeb yaj kiab biodegradable?
Kev khaws cia thiab thauj khoom kom raug yog qhov tseem ceeb los khaws cov khoom zoo thiab kev ua haujlwm ntawm biodegradable films:
Environmental tswj:
Khaws rau hauv cov xwm txheej hauv qab 30 ° C thiab cov av noo qis dua 60%. Thaum tshav kub kub thiab av noo tuaj yeem ua rau muaj kev puas tsuaj thaum ntxov lossis cuam tshuam rau cov khoom siv kho tshuab.
Txuag lub neej taug qab
Qhia meej meej txog hnub tsim khoom thiab pom zoo siv los ntawm lub sijhawm (feem ntau yog 6-12 lub hlis), tshwj xeeb tshaj yog rau cov yeeb yaj kiab uas siv rau hauv cov khoom noj-hu rau lossis daim ntawv thov sealing.
Kev tiv thaiv ntim:
Siv cov khoom ntim hauv cov dej noo (xws li cov hnab ntawv ci) thiab daim ntawv lo kom meej nrog cov lus qhia tuav kom tsis txhob degradation thaum lub sij hawm thauj mus los.
Ua cov kauj ruam tiv thaiv kom ntseeg tau tias cov yeeb yaj kiab ua tau raws li qhov xav tau thaum lawv ncav cuag tus neeg siv khoom.
Yuav ua li cas qhov zoo thiab sib xws ntawm biodegradable films yuav ua kom ntseeg tau?
Kev tuav tswj tau zoo thiab ua tau zoo ib yam hauv cov yeeb yaj kiab biodegradable muaj ntau yam kev coj ua zoo tshaj plaws:
Kev tiv thaiv ntim:
Xaiv cov neeg tsim khoom tau lees paub rauISO 9001 Daim ntawv pov thawjthiab ua raws li cov qauv tsim nyog xws liTS EN 13432, ASTM D 6400 Cov Lus Qhia Tshwj Xeeb, los yogBPI.

Thib peb-tog validation
Koom nrog cov chaw sim rau kev sim ywj pheej ntawm compostability lossis mechanical kev ua tau zoo yog tias xav tau.
Kev sim hauv daim ntawv thov
Ua cov kev sim ntim khoom ntawm cov kab ntim khoom / sealing tiag tiag txhawm rau txheeb xyuas kev sib raug zoo thiab kev ua haujlwm hauv lub ntiaj teb tiag tiag.
Dab tsi yog yav tom ntej tiam sis nyob rau hauv biodegradable films?
Kev sim hauv daim ntawv thov
-
Next-gen cov ntaub ntawvzoo li PHA (polyhydroxyalkanoates), uas yog marine biodegradable.
-
Txhim kho tsev compostable dawsuas ua haujlwm nyob rau hauv qis-kub, qis-humidity ib puag ncig.
-
Txhim khu kev tiv thaiv technologysiv biodegradable coatings los yog nano-additives.
-
Kev txhawb zog los ntawm kev ua liaj ua teb pov tseg(piv txwv li, bagasse, seaweed) kom txo tau cov zaub mov kev sib tw.
Raws li txoj cai tswjfwm xws li EU Green Deal thiab thoob ntiaj teb cov yas txwv nruj nruj, biodegradable zaj duab xis xav tau thiab kev tsim kho tshiab yuav loj hlob ntxiv, tshwj xeeb tshaj yog rau kev lag luam e-lag luam, khoom kim heev, thiab eco-conscious FMCG sectors.
