Yog tias koj xav kom koj cov khoom muaj kev nyab xeeb thiab ruaj ntseg rau kev muag khoom, tej zaum koj twb pom tias shrink film tuaj yeem pab koj ua li ntawd.Muaj ntau ntau hom shrink zaj duab xis nyob rau hauv kev ua lag luam niaj hnub no yog li nws yog ib qho tseem ceeb kom tau txais yam zoo.Tsis tsuas yog yuav xaiv txoj cai shrink zaj duab xis pab tiv thaiv koj cov khoom ntawm lub txee, tab sis nws tseem yuav txhim kho kev yuav khoom rau koj cov neeg siv khoom lossis cov neeg yuav khoom.
Tawm ntawm ntau hom shrink zaj duab xis, peb hom yeeb yaj kiab tseem ceeb ntawm kev ua lag luam koj yuav xav tshuaj xyuas yog PVC, Polyolefin, thiab Polyethylene.Cov shrink films txhua tus muaj cov khoom uas hla mus rau ntau daim ntawv thov, tab sis cov yam ntxwv tshwj xeeb ntawm cov yeeb yaj kiab no yuav ua rau lawv haum rau koj qhov kev siv.
Nov yog qee qhov ua tau zoo thiab qhov tsis muaj zog ntawm txhua hom shrink zaj duab xis los pab koj xaiv qhov twg yuav yog qhov zoo tshaj plaws rau koj daim ntawv thov.
● PVC (tseem hu ua Polyvinyl Chloride)
Lub zog
Cov yeeb yaj kiab no yog nyias, pliable, thiab lub teeb, feem ntau pheej yig dua li feem ntau shrink films.Nws tsuas yog shrinks nyob rau hauv ib qho kev taw qhia thiab yog heev resistant rau tearing los yog punctureing.PVC muaj qhov pom tseeb, ci ntsa iab, ua kom zoo nkauj rau lub qhov muag.
Tsis muaj zog
PVC softens thiab wrinkles yog qhov kub thiab txias heev, thiab nws yuav nyuaj thiab nkig yog tias nws txias.Vim tias cov yeeb yaj kiab muaj cov tshuaj chloride hauv nws, FDA tsuas yog pom zoo PVC zaj duab xis rau siv nrog cov khoom siv tsis tau.Qhov no kuj ua rau nws tawm cov pa phem thaum lub sij hawm cua sov thiab sealing, ua rau nws yuav tsum tau siv nyob rau hauv qhov zoo-ventilated qhov chaw.Cov yeeb yaj kiab no kuj muaj cov qauv pov tseg nruj.PVC feem ntau tsis haum rau bundling ntau yam khoom.
● Polyolefin
Lub zog
Hom zaj duab xis shrinkage no yog FDA pom zoo rau kev sib cuag zaub mov vim nws tsis muaj chloride nyob rau hauv nws, thiab nws tsim muaj ntxhiab tsw ntau thaum cua sov thiab sealing.Nws yog qhov zoo dua rau cov pob khoom tsis sib xws raws li nws shrinks ntau dua.Cov yeeb yaj kiab muaj qhov zoo nkauj, glossy nto thiab yog qhov tseeb tshwj xeeb.Tsis zoo li PVC, nws tuaj yeem tiv taus ntau qhov kub ntawm qhov hloov pauv thaum khaws cia, txuag cov khoom muag.Yog tias koj xav tau ntim ntau yam khoom, polyolefin yog qhov kev xaiv zoo.Tsis zoo li PE, nws tsis tuaj yeem qhwv ntau pob khoom hnyav.Hla-txuas polyolefin kuj tseem muaj uas ua rau nws lub zog tsis muaj kev cuam tshuam qhov tseeb.Polyolefin tseem yog 100% recyclable, ua rau nws xaiv "ntsuab".
Tsis muaj zog
Polyolefin yog kim tshaj li PVC zaj duab xis, thiab nws kuj yuav tsum tau perforations nyob rau hauv tej daim ntawv thov kom tsis txhob muaj huab cua hnab ris los yog bumpy nto.
● Polyethylene
Qee cov ntaub ntawv ntxiv: Polyethylene zaj duab xis tuaj yeem siv rau cov yeeb yaj kiab shrink lossis stretch zaj duab xis, nyob ntawm daim ntawv.Koj yuav tsum paub tias daim ntawv twg koj xav tau rau koj cov khoom.
Cov neeg tsim khoom tsim cov polyethylene thaum ntxiv ethylene rau polyolefin thaum lub sijhawm txheej txheem polymerization.Muaj peb hom polyethylene: LDPE lossis Low-density Polyethylene, LLDPE lossis Linear Low-density Polyethylene, thiab HDPE lossis High-density polyethylene.Lawv txhua tus muaj ntau yam kev siv, tab sis feem ntau, LDPE daim ntawv yog siv rau shrink film ntim.
Lub zog
Muaj txiaj ntsig zoo rau kev qhwv ntau pob khoom hnyav-piv txwv li, suav nrog ntau cov dej haus lossis lub raj mis dej.Nws yog qhov ruaj khov thiab muaj peev xwm ncab ntau dua li lwm cov yeeb yaj kiab.Raws li nrog polyolefin, polyethylene yog FDA pom zoo rau kev sib cuag zaub mov.Thaum PVC thiab polyolefin films yog txwv nyob rau hauv thickness, feem ntau tsuas yog mus txog 0.03mm, polyethylene yuav scaled mus txog 0.8mm, ua rau nws zoo tagnrho rau wrapping tsheb xws li tej nkoj nquam cia.Siv ntau yam khoom noj los yog khov rau cov hnab khib nyiab thiab palletizing li stretch wrapping.
Tsis muaj zog
Polyethylene muaj qhov txo qis ntawm 20% -80% thiab tsis meej npaum li lwm cov yeeb yaj kiab.Polyethylene shrinks thaum txias tom qab nws tau rhuab, ua rau nws yuav tsum muaj qhov chaw ntxiv rau qhov txias ntawm qhov kawg ntawm koj qhov shrinkage.
