Kana iwe uchida kuchengetedza chigadzirwa chako chakachengeteka uye chakachengeteka kutengeswa, unogona kunge watoona iyo shrink firimu inogona kukubatsira kuita izvozvo.Kune akawanda marudzi e shrink film pamusika nhasi saka zvakakosha kuti uwane mhando chaiyo.Kwete chete kusarudza iyo chaiyo mhando ye shrink firimu inobatsira kuchengetedza chigadzirwa chako pasherufu, asi zvakare inosimudzira ruzivo rwekutenga kune vatengi vako kana vatengi.
Kubva mumhando dzakawanda dzefirimu shrink, mhando nhatu huru dzefirimu pamusika wauchazoda kuongorora iPVC, Polyolefin, uye Polyethylene.Aya mafirimu anoonda ega ega ane zvivakwa zvinoyambuka kune akasiyana maapplication, asi chaiwo maitiro emafirimu aya anogona kuita kuti anyanyokodzera kushandiswa kwako.
Heano mamwe masimba uye kusasimba kweimwe neimwe mhando ye shrink firimu kuti ikubatsire kusarudza kuti ndeipi ingave yakanakira application yako.
● PVC (inozivikanwawo sePolyvinyl Chloride)
Simba
Iyi firimu yakatetepa, inochinjika, uye yakareruka, kazhinji inotengeka kupfuura mafirimu mazhinji anoderera.Inodzikira munzira imwe chete uye inoshingirira zvakanyanya kubvaruka kana kuboora.PVC ine yakajeka, inopenya mharidzo, ichiita kuti inakidze mumeso.
Utera
PVC inopfava uye kuita kuunyana kana tembiricha ikakwira zvakanyanya, uye inova yakaoma uye brittle kana ikatonhora.Nekuti iyo firimu ine chloride mairi, iyo FDA yakangobvumidza PVC firimu kuti rishandiswe nezvisingadyike zvigadzirwa.Izvi zvinokonzeresa kuti ibudise utsi hune muchetura panguva yekudziya nekuvhara, zvichiita kuti ishandiswe munzvimbo dzinonyatsofefetera.Iyi firimu saka zvakare ine yakasimba yekurasa zviyero.PVC haina kazhinji yakakodzera kuunganidza zvigadzirwa zvakawanda.
● Polyolefin
Simba
Iyi shrink firimu mhando ndeye FDA yakatenderwa kubata chikafu sezvo isina chloride mairi, uye inoburitsa kunhuhwirira kwakawanda panguva yekudziya nekuisa chisimbiso.Yakanyatsokodzera mapakeji asina kurongeka sezvo ichiderera zvakanyanya.Iyi firimu ine nzvimbo yakanaka, inopenya uye yakajeka.Kusiyana nePVC, inogona kumira nehupamhi hwakawanda hwekushanduka kwekushisa kana yakachengetwa, ichichengetedza hesiti.Kana iwe uchida kuunganidza zvinhu zvakawanda, polyolefin isarudzo huru.Kusiyana nePE, haigone kuputira akawanda-mapaketi ezvinorema zvinhu.Cross-yakabatana polyolefin inowanikwawo iyo inowedzera simba rayo pasina kupa kujekesa.Polyolefin zvakare 100% inogona kushandiswazve, ichiita iyo "yegirini" sarudzo.
Utera
Polyolefin inodhura kupfuura firimu rePVC, uye rinogonawo kuda maperforations mune mamwe maapplication kudzivirira homwe dzemhepo kana nzvimbo dzine mabumbu.
● Polyethylene
Rumwe ruzivo rwekuwedzera: Firimu repolyethylene rinogona kushandiswa kufinya firimu kana kutambanudza firimu, zvichienderana nechimiro.Iwe unozofanirwa kuziva kuti ndeipi fomu yaunoda kune yako chigadzirwa.
Vagadziri vanogadzira polyethylene kana vachiwedzera ethylene kune polyolefin panguva yekuita polymerization.Kune marudzi matatu akasiyana ePolyethylene: LDPE kana Low-density Polyethylene, LLDPE kana Linear Low-density Polyethylene, uye HDPE kana High-density polyethylene.Iwo ega ega ane akasiyana maapplication, asi kazhinji, iyo LDPE fomu rinoshandiswa shrink firimu kurongedza.
Simba
Inobatsira pakuputira akawanda-pack yezvinhu zvinorema-somuenzaniso, nhamba huru yezvinwiwa kana mabhodhoro emvura.Inogara yakasimba uye inokwanisa kutambanudza kupfuura mamwe mafirimu.Sezvakaita polyolefin, polyethylene ndiyo FDA yakatenderwa kubata chikafu.Nepo PVC nepololefin mafirimu akaganhurirwa mukukora, kazhinji anongosvika 0.03mm, polyethylene inogona kukwiridzirwa kusvika pa 0.8mm, zvichiita kuti ive yakanaka yekuputira mota senge mabhoti ekuchengetera.Mashandisirwo anotangira kubva kuhuwandu kana chikafu chakaomeswa kusvika kumabhegi emarara uye palletizing sekuputira.
Utera
Polyethylene ine shrink rate inosvika 20% -80% uye haina kujeka semamwe mafirimu.Polyethylene inodzikira paunenge uchitonhodza mushure mekunge yadziiswa, zvichiita kuti kuve nekuwedzera nzvimbo yekutonhodza pamagumo emugero wako wekupfava.
