Heat shrink film labelsmagwaro matete emufirimu akadhindwa pamafirimu epurasitiki kana machubhu achishandisa inki ine hunyanzvi.Munguva yekunyora manyorero, kana yapiswa (yakatenderedza 70 ℃), iyo shrink label inokurumidza kunyura parutivi rwekunze contour yemudziyo uye inonamira zvakasimba pamusoro pemudziyo.Heat shrink film labels inonyanya kusanganisira shrink sleeve label uye shrink wrap label.
Maitiro ekushanda
Shrinkage sleeve label i cylindrical label yakagadzirwa kubva kupisa shrink firimu se substrate, iyo inodhindwa ichibva yagadzirwa.Iyo ine hunhu hwekushandisa zviri nyore uye yakanyatsokodzera kune yakakosha-yakaita midziyo.Marebhurari ekukwenya anowanzoda midziyo yehunyanzvi yekuvharisa iyo yakadhindwa mugaba.Chekutanga, mudziyo wekunyora unovhura iyo yakavharwa cylindrical sleeve label, iyo dzimwe nguva inoda kudhiriwa;Zvadaro, cheka label muhukuru hwakakodzera uye uiise pamudziyo;Wobva washandisa chiutsi, infrared, kana mhepo inopisa yekurapa kupisa kuti ubatanidze iyo label pamusoro pemudziyo.
Nekuda kwekujeka kwepamusoro kwefirimu pachayo, iyo label ine inopenya uye inopenya ruvara.Nekudaro, nekuda kwekuda kwekuderera panguva yekushandiswa, pane dhizaini yemaitiro deformation, kunyanya kune zvigadzirwa zvakadhindwa nebarcode markings.Yakasimba dhizaini uye kudhinda kwemhando yekudzora kunofanirwa kuitwa, zvikasadaro deformation yepateni ichaita kuti bhakodhi mhando ive isina kukodzera.Shrink wrap labels inogona kunyorwa uchishandisa zvechinyakare labeling midziyo, iyo inoda kushandiswa kweanonamira uye tembiricha yepamusoro panguva yekunyora.Munguva ye shrinkage process, inopisa kunyunguduka adhesive inosarudzwa nekuda kwekunetseka kunogadzirwa neadhesive pane anopindirana zvikamu zvefirimu.

Nekuda kwekutikupisa kupisa firimuiyo thermoplastic firimu inotungamirwa nekutambanudza panguva yekugadzira uye inoderera panguva yekushandiswa.Naizvozvo, zvisinei kuti ndeipi nzira yekudhinda inoshandiswa pakudhinda, usati wagadzira iyo yepamusoro peteni, yakatwasuka uye yakatwasuka shrinkage mazinga echinhu, pamwe neanotenderwa zvikanganiso zve deformation mumativi akasiyana-siyana ekushongedza magirafu uye zvinyorwa mushure mekuderera, zvinofanirwa kutariswa. kuve nechokwadi chekudzoreredza kwakaringana kwepateni, zvinyorwa, uye barcode zvakanyura mumudziyo.
Nzira yemuenzaniso
Kanakupisa kupisa firimuinodhindwa ichishandisa gravure printing kana flexographic printing, kudhinda kwayo kunonyanya kudhinda nzira yemukati, uye gwara rinoenderana nepateni pandiro yekutsikirira kunofanirwa kuve kwakanaka.Mazuva ano, kune zvakare shrink mafirimu ekudhindwa kwepamusoro.Muchiitiko ichi, nhungamiro yemuenzaniso pane ndiro yekudhinda inofanira kuchinjwa.
Hurongwa hwemapatani
Nekuda kwekugumira kwe flexographic printing, kana iyo shrink firimu yakadhindwa uchishandisa flexographic printing, chiyero chemufananidzo hachifanirwe kunge chakanyanya kutetepa, nepo kushandisa gravure kudhinda kungada nhanho yakapfuma yemufananidzo.
Dhizaini yezviyero
Iyo yakachinjika shrinkage mwero wekupisa shrink firimu zvinhu zvinoshandiswa kudhinda 50% kusvika 52% uye 60% kusvika 62%, uye inogona kusvika 90% mumamiriro ezvinhu akasarudzika.The longitudinal shrinkage rate inodiwa kuva 6% kusvika 8%.Nekudaro, panguva yekumisikidzwa kwepakarepo kwefirimu, nekuda kwekugumira kwegaba, iyo yakatwasuka uye yakatwasuka nzira haigone kubatwa zvizere.Kuve nechokwadi chekudzoreredza kwakaringana kweiyo chibvumirano pateni, zvinyorwa, uye barcode, zvinodikanwa kuti utarise chimiro chemudziyo uye kuverenga saizi chaiyo uye deformation rate zvichienderana nemamiriro chaiwo.Nezve kupisa shrink mavara anoda kushandura mapepa-akaita semafirimu kuita cylindrical zvimiro uye kuvhara nzvimbo dzakapoteredzwa pamwe chete neadhesive, zvakakosha kuti uzive kuti hapana magiraidhi kana zvinyorwa zvinofanirwa kugadzirwa panzvimbo dzekuisa chisimbiso kudzivirira kukanganisa simba rekubatanidza.
