Shrink label inonyanya kuchinjika, mapurasitiki, simbi, girazi uye zvimwe zvekurongedza midziyo zvinogona kuve zvakashongedzwa, shrink firimu sleeve label nekuda kwekusanganiswa kwemhando yepamusoro mapatani uye yakasarudzika modhi, inowedzera uye inozivikanwa pamusika.Iri bepa rinotsanangura hunhu uye zvakanakira contraction firimu label uye misimboti yekusarudza zvinhu, zvirimo zvereferensi yeshamwari:
Shrink film sleeve label
Shrinkable firimu seti yemavara ndeye chikamu chekupisa shrinkable firimu, ipurasitiki firimu kana mabhii ari kubuda akadhindwa papombi yepurasitiki, kunyanya kusanganisira PE, PVC, PET, senge yakajairika mhando kupisa shrinkable firimu, nekuti iyo shrinkable firimu seti. inzvimbo yakatambanudzwa mukugadzira, uye mukuita kwekushandisa kupisa kuderera kweiyo thermoplastic plastiki firimu.Naizvozvo, pamberi pekugadzirwa kwechimiro chepamusoro, tinofanirwa kufunga nezve yakachinjika uye yelongitudinal shrinkage mwero wezvinhu, pamwe nekukanganisa kwedeformation kunobvumidzwa kumativi ese ekushongedza chinyorwa mushure mekumisikidza, kuitira kuti ive nechokwadi chekudzikisa kwakaringana kwepateni. , mameseji uye bar kodhi yakanyura mumudziyo.
01 Azvakanakira
Shrink-wrap label ifirimu set label yakadhindwa papurasitiki firimu kana epurasitiki chubhu.Ine zvinotevera maitiro:
1) Shrink film sleeve label processing iri nyore, kurongedza chisimbiso, anti-kusvibisa, kuchengetedzwa kwakanaka kwezvinhu;
2) Chifukidzo chemufirimu chiri pedyo nenhumbi, iyo pasuru inosungirirana, uye inogona kuratidza chimiro chemidziyo, saka yakakodzera kune zvinhu zvisina kujairika izvo zvakaoma kutakura;
3) Shrink film sleeve label labeling, pasina kushandiswa kwekunamira, uye inogona kuwana kujeka kwakafanana segirazi;
4) Shrink-yakaputirwa label inogona kupa 360 ° kushongedza kwegaba rekurongedza, uye inogona kudhinda ruzivo rwechigadzirwa senge tsananguro yechigadzirwa pane iyo label, kuitira kuti vatengi vanzwisise kuita kwechigadzirwa pasina kuvhura pasuru;
5) Kudhindwa kweiyo label ye shrink film sleeve ndeyekudhindwa mufirimu (chinyorwa uye mufananidzo zviri mukati meiyo firimu sleeve), iyo inogona kudzivirira kufungidzira uye ine nani kupfeka kuramba.
02 Dhizaina zvakakosha uye misimboti yekusarudza zvinhu
The label design
Iyo dhizaini yekushongedza maitiro pafirimu inofanirwa kutariswa maererano nehupamhi hwefirimu.Paunenge uchigadzira iyo pateni, zvinodikanwa kujekesa iyo inochinjika uye yakareba shrinkage chiyero chemufirimu, pamwe neinobvumidzwa shrinkage mwero munzira yega yega mushure mekurongedza uye inotenderwa deformation kukanganisa kweyekushongedza patani mushure mekuderera, kuitira kuti uve nechokwadi chekuti iyo muenzaniso uye zvinyorwa mushure mekuderera zvinogona kudzorerwa zvakarurama.
Firimu ukobvu uye shrinkage
Zvishandiso zvinoshandiswa kune shrinkable film cover labels zvinofanirwa kutarisa pazvinhu zvitatu: kwezvakatipoteredza zvinodiwa, firimu ukobvu uye shrinkage kuita.
Ukobvu hwefirimu hunotarwa zvichienderana nemunda wekushandisa uye mutengo wezvinhu zveiyo label.Ehe, mutengo hausi iwo unosarudza, sezvo firimu rega rega rakasiyana uye vese mushandisi neprinta yezita vanofanirwa kuve vakajeka nezve firimu uye maitiro akanyatsokodzera kune izvo zvinhu zvisati zvasaina.Mukuwedzera, iyo indekisi inodikanwa nemichina yekugadzirisa uye mamwe maitiro ekugadzirisa anokanganisawo zvakananga kusarudzwa kwekukora.Zvinowanzodiwa kuti firimu yefirimu ye shrink-sleeve label ndeye 30-70 μm, pakati payo 40μm uye 50μm inowanzoshandiswa.
Mukuwedzera, iyo firimu shrinkage rate ine zvimwe zvinodiwa, uye lateral (TD) shrinkage rate yakakwirira kudarika longitudinal (MD) shrinkage rate.Iyo yakachinjika shrinkage yezvinhu zvakajairika ndeye 50% ~ 52% uye 60% ~ 62%, uye inogona kusvika 90% mune yakakosha kesi.Longitudinal shrinkage rate inodiwa mu6% ~ 8%.Paunenge uchigadzira shrinkable film sleeve labels, zvinhu zvine diki longitudinal shrinkage zvinofanirwa kusarudzwa zvinokwanisika.
03 Firimu zvinhu
Zvishandiso zvekugadzira label ye shrinkage film cover iPVC (PVC) film, pet (polyester) film, peg (modified polyester) film, ops (oriented polystyrene) film, etc. Kuita kwayo kunotevera:
PVC firimu PVC
firimu ndiyo inonyanya kushandiswa firimu zvinhu pari zvino.Iyo yakachipa, ine yakakura tembiricha shrinkage siyana uye haina yakakwirira zvinodiwa pakupisa sosi.Iyo huru yekugadzirisa kupisa sosi ndeyekusanganiswa kwemhepo inopisa, infrared mwenje kana zvese zviri zviviri.Zvisinei, PVC yakaoma kudzorerazve, kana kupisa gasi, iyo isingaiti kuchengetedza kwezvakatipoteredza, yakarambidzwa muEurope neJapan.
OPSfilm
Sekutsiva mafirimu ePVC, mafirimu eOPS akashandiswa zvakanyanya.Kuita kwayo shrinkage kwakanaka, kunobatsirawo kuchengetedza kwezvakatipoteredza.Musika wepamusha wechigadzirwa ichi uri kushomeka, uye parizvino, yemhando yepamusoro OPS inonyanya kuenderana nekunze, izvo zvave chinhu chakakosha chinomisa kusimudzira kwayo.
PETGfilm
PETG copolymer firimu haingobatsiri kuchengetedza kwezvakatipoteredza, asi zvakare inogona kugadzirisa shrinkage rate pamberi.Nekudaro, nekuda kwekunyanya shrinkage, ichave zvakare shoma mukushandisa.
PETfilm
PET firimu imhando inozivikanwa pasi rese yezvakatipoteredza mhando inopisa shrinkage firimu zvinhu.Zviratidziro zvayo zvehunyanzvi, zvimiro zvemuviri, huwandu hwemashandisirwo uye nzira dzekushandisa dziri pedyo nePVC inopisa kupisa firimu, asi yakachipa kupfuura PETG, inova yakanyanya kukwirisa unidirectional shrinkage firimu parizvino.Yayo yakachinjika shrinkage mwero i70%, iyo longitudinal shrinkage rate iri pasi pe3%, uye haina chepfu uye isina kusvibiswa-isina, inova ndiyo yakanyanya kunaka zvinhu kutsiva PVC.
04 Firimu cover label printing printing Yakadhindwa pamafirimu akasarudzwa.
Parizvino, kudhindwa kwe shrinkage film sleeve kunonyanya kushandiswa mukudhinda gravure, solvent printing inki, inoteverwa neinochinjika kudhinda.Nekuvandudzwa kwe flexo tekinoroji, ruvara rwekudhinda rwakajeka uye rwakajeka, runogona kufananidzwa nekudhindwa kwegravure, ine gobvu uye yakakwirira gloss ye gravure.Mukuwedzera, flexo yakawanda inoshandisa mvura-based inki, inogadzirisa kuchengetedza kwezvakatipoteredza.Kucheka nemhando yepamusoro yekucheka muchina uchashandiswa kucheka yakadhindwa reel film material longitudinal cutting, uye nechekumucheto chikamu chefirimu chichagadziriswa kuti chiite chakatsetseka, chakapfava uye chisingaiti.Paunenge uchishandisa muchina wekucheka, teerera kuti usapisa blade, nekuti iyo inopisa blade inogona kuita kuti firimu richekwe kukwinya.Iyo suture yefirimu mushure mekucheka kwenguva refu inoitwa nemushini we suture, uye muromo wechubhu unosungirirwa kuti uite membrane sleeve inodiwa pakurongedza.Iyo yemidziyo margin inodiwa kune suture inoenderana nekurongeka kwesuture uye hunyanzvi hwemushandisi.Iyo yakawanda inokurudzirwa huwandu hwesuture ndeye 10mm, kazhinji 6mm.Shandura kucheka nekuputira chivharo chefirimu kunze kwechigadzirwa, uye kucheka firimu rakachinjika zvinoenderana nehukuru hwekurongedza.Pakudziya kwakakodzera tembiricha, kureba uye hupamhi hwefirimu ye shrinkage inodzikira zvakanyanya (15% ~ 60%).Kazhinji, saizi yefirimu inodiwa kuti iite 10% yakakura pane yakakura saizi yechigadzirwa.Heat shrinkage inopisa negwara rinopisa, hovhoni inopisa, kana pfuti yemhepo inopisa.Panguva ino, iyo shrink label ichakurumidza kuderera pamwe nekunze contour yemudziyo, yakanyatsoenderana nekunze contour yemudziyo, ichigadzira label rekudzivirira iro rinonyatsoenderana nechimiro chemudziyo.Mukugadzira shrinkage firimu sleeve label, zvinodikanwa kuita kutarisisa kwega kwega maitiro kuburikidza nemuchina wakasarudzika wekuona kuti ive nechokwadi chekugadzira.Chiyero chinoshanda che shrink label chinochinjika, chinogona kushandiswa pakushongedza kwepamusoro, kushongedzwa kwehuni, bepa, simbi, girazi, ceramics uye zvimwe midziyo yekurongedza, inoshandiswa zvakanyanya muchikafu, zvigadzirwa zvemakemikari zvemazuva ese, zvigadzirwa zvemakemikari kurongedza uye kushongedza, zvakadai. sezvinwiwa zvakasiyana-siyana, zvizoro, chikafu chevana, kofi uye zvichingodaro.
