PET High Glossy Firimu
Pamusoro pezvakanakisa zvemuviri uye zvemagetsi zvimiro zveakajairwa polyester firimu, iyo firimu zvakare ine yakanakisa optical zvimiro, seyakanaka kujeka, yakaderera haze uye yakakwirira gloss.Inonyanya kushandiswa kune yakakwirira-giredhi vacuum aluminized zvigadzirwa, iyo firimu inoratidzwa mushure mealuminium, iyo ine yakanaka yekurongedza yekushongedza mhedzisiro;inogonawo kushandiswa kune laser laser anti-counterfeiting base film, etc. High gloss BOPET firimu ine misika yakakura yemusika, yakakwirira yakawedzerwa kukosha uye zviri pachena zvikomborero zvehupfumi.
PET kutumira firimu
Firimu rekufambisa, iro rinozivikanwawo sefirimu rekutamisa kupisa, rinoratidzwa nekusimba kwakasimba, kugadzikana kwakanaka kwekushisa, kushomeka kwekushisa, kuputika uye kutsetseka kwepamusoro, kunaka peelability, uye inogona kushandiswa kakawanda.Inonyanya kushandiswa semutakuri wevacuum aluminizing, ndiko kuti, mushure mekunge PET firimu rave nealuminium mumushini wevacuum aluminizing, rinoputirwa neadhesive uye rakamisikidzwa nepepa, uyezve iyo PET firimu inobviswa, uye aluminium molecular layer. inotamirwa pamusoro pekadhibhodhi kuburikidza neadhesive effect, ichigadzira iyo inonzi inonzi aluminized cardboard.Maitiro ekugadzira ealuminium kadhibhodhi ndeye: PET base firimu → kuburitsa layer → color layer → aluminized layer → adhesive coated layer → kuendesa kumakadhibhodi.
Vacuum aluminized kadhibhodhi imhando yemakadhibhodi ane simbi inopenya, inova rudzi rwemhando yepamusoro yekurongedza zvinhu yakagadziriswa mumakore achangopfuura.Iri rudzi rwealuminum makadhibhokisi ane ruvara rwakajeka, yakasimba simbi pfungwa uye inopenya uye inoyevedza kudhinda, iyo inogona kutsiva nzvimbo yakakura yekupisa yekutsikirira yezvinhu zvakadhindwa uye kuita basa reicing pakeke rekushongedza kwezvinhu.Nekuti inotora nzira yevacuum aluminizing, pamusoro pekadhibhodhi inongofukidzwa neakatetepa uye akaomarara layer ye0.25um ~ 0.3um aluminium layer, inongove chikamu chimwe chete muzvishanu chealuminium foil layer yelaminated aluminium kadhibhodhi, kuitira kuti. ine zvese zvine mbiri uye yakanaka simbi mameseji, asi zvakare ine inoshatisa uye inogona kudzokororwa kuchengetedzwa kwemamiriro ekunze, uye ndeye yakasvibira yekurongedza zvinhu.
PET inoratidzira firimu
PET inoratidzira firimu inoratidzirwa neakanakisa optical zvimiro, yakatsetseka uye yakatsetseka pamusoro, yakanaka yekudziya kugadzikana, diki shrinkage rate uye kureruka kuchembera kuramba.
Kune mhando mbiri dzezvinhu zvinoratidzira zvinoshandiswa muzvivakwa zvetraffic: lens-mhando yedirectional inotaridza firimu uye flat-yepamusoro inoratidzira firimu, ese ari maviri anoshandisa aluminized PET firimu seyairatidzira layer, pane akati wandei egirazi mabhedhi ane refractive index ye1.9. yakanamatira kuPET aluminized firimu mushure mekuputirwa nepressure-sensitive adhesive, uye yobva yapfapfaidzwa nedhiri rebutyral pamusoro pekudzivirira layer.
PET inotaridza firimu inoiswa kumabhodhi ane zvinoratidzira zvinodiwa, zviratidzo zvetraffic zvinoratidzira (zviratidziro zvemumugwagwa zvinoratidzira, zvinoratidzira zvipingamupinyi, zvinoratidzira nhamba dzemotokari), mayunifomu emapurisa anoratidza, zviratidzo zvekuchengetedza maindasitiri, nezvimwe.

Kuti uvandudze nzvimbo dzepamusoro dzePET mafirimu kuitira kudhindwa zviri nani uye kusungirirwa kwevacuum aluminizing layer, kurapwa kwekona kunowanzo shandiswa kuwedzera kushushikana kwepamusoro kwemafirimu.Nekudaro, iyo nzira yekorona ine matambudziko akadai sekuenderana nenguva, kunyanya mukupisa kwakanyanya uye hunyoro hwakanyanya nharaunda, uye kunetsana kwemafirimu akabatwa nekorona anogona kuora nyore.Iyo kemikari yekuputira nzira, zvisinei, haina matambudziko akadaro uye inofarirwa nemaindasitiri ekudhinda uye aluminizing.Uye zvakare, iyo yekubikira nzira inogona zvakare kushandiswa kugadzira yakakwirira barriers mafirimu uye antistatic mafirimu, nezvimwe.
PET anti-static firimu
Nyika yanhasi yapinda muzera reruzivo, ma frequency akasiyana uye mafungu emagetsi emagetsi akazadza nzvimbo yese yepasi, aya mafungu emagetsi emagetsi achave asina kuvharwa anonzwa emagetsi emagetsi, mabhodhi edunhu, midziyo yekutaurirana, nezvimwe zvinogadzira akasiyana madhigirii ekukanganisa, zvichikonzera kukanganisa data. , kukanganisa kutaurirana.Uye electromagnetic induction uye friction inogadzirwa static magetsi pane akasiyana siyana anonzwa zvinhu, zviridzwa, zvimwe makemikari zvigadzirwa, nezvimwe, sekuunganidzwa kweelectrostatic discharge nekuda kwekurongedza firimu, mhedzisiro yacho ichave inoparadza, saka kusimudzira kweanti-static PET yekurongedza firimu. kunokoshawo zvikuru.Chinhu che antistatic firimu ndechekuti nekuwedzera imwe mhando yeantistatic agent muPET firimu, yakaonda kwazvo conductive layer inoumbwa pamusoro peiyo firimu kuti ivandudze iyo yepamusoro conductivity, kuitira kuti iyo inogadzirwa charge inogona kuburitswa nekukurumidza sezvinobvira.
PET Kupisa Chisimbiso Firimu
PET firimu icrystalline polymer, mushure mekutambanudza uye kutarisisa, PET firimu rinoburitsa dhigirii rakakura recrystallization, kana iri kupisa rakavharwa, rinoburitsa shrinkage uye deformation, saka rakajairwa PET firimu harina kupisa sealing performance.Kusvika kumwero wakati, kushandiswa kweBOPET firimu kunogumira.
Kuti tigadzirise dambudziko rekuvharwa kwekupisa, takagadzira matatu-layer co-extruded heat-sealable PET firimu nekugadzirisa PET resin uye kutora matatu-layer A/B/C chimiro chinofa, chiri nyore kushandisa nekuti rimwe divi re. iyo firimu inopisa-inovharwa.Heat-sealable PET mafirimu anogona kushandiswa zvakanyanya muminda yekurongedza uye makadhi ekudzivirira mafirimu ezvigadzirwa zvakasiyana.
PET kupisa kupisa firimu
Polyester heat shrink firimu imhando nyowani yekupisa shrink yekurongedza zvinhu.Nekuda kwekudzokorodza kwayo kuri nyore, kusiri muchetura, kusinganakidze, kwakanaka kwemagetsi zvivakwa, kunyanya zvinoenderana nekuchengetedzwa kwezvakatipoteredza, polyester (PET) yave nzvimbo yakanaka yekutsiva polyvinyl chloride (PVC) inopisa-kupisa firimu munyika dzakabudirira.Nekudaro, yakajairwa polyester icrystalline polymer, uye yakajairwa PET firimu inogona chete kuwana kupisa kwekudzikira kweisingasviki 30% mushure mekuita kwakakosha.Kuti uwane mafirimu epolyester ane kupisa kwepamusoro shrinkage, anofanirawo kuchinjwa.Mune mamwe mazwi, kuitira kuti ugadzirire mafirimu epolyester ane kupisa kwakanyanya shrinkage, copolymerization kugadziriswa kwepolyester yakajairika, kureva polyethylene terephthalate, inodiwa.Iyo yakanyanya kupisa shrinkage yecopolymer-yakagadziridzwa PET mafirimu inogona kusvika ku70% kana kupfuura.
Maitiro ekupisa-shrinkable polyester firimu: inogadzikana pakupisa kwekamuri, inoderera kana ichipisa, uye inopfuura 70% kupisa kuderera kunoitika mune imwe nzira.Zvakanakira kupisa-kupisa polyester firimu kurongedza ndeiyi: ① Transparent kuti ikwane muviri uye kuratidza mufananidzo wezvinhu.②Yakanyatso kuputirwa, yakanaka anti-kupararira.③ kusanaya kwemvura, hunyoro-uchapupu, mold-proof.④Hapana kupora, neimwe anti-yekunyepedzera basa.Heat shrinkable polyester firimu inowanzoshandiswa mukugadzirisa chikafu, musika wechinwiwa, zvemagetsi nemagetsi, zvigadzirwa zvesimbi, kunyanya shrinkable label ndiyo inonyanya kukosha nzvimbo yekushandisa.Nekuti nekukurumidza kuvandudzwa kwemabhodhoro ezvinwiwa ePET, akadai seCoke, Sprite, majusi emichero akasiyana uye mamwe mabhodhoro ezvinwiwa anoda PET inopisa inopisa firimu nayo kuti iite kupisa sealing labels, ndeeboka rimwe chete repolyester, zvinhu zvine hushamwari zvakatipoteredza, zviri nyore. kudzokorodza uye kushandisazve.
Kuwedzera kune shrink labels, kupisa shrink polyester firimu rakatangawo kushandiswa pakurongedza kwekunze kwezvinhu zvemazuva ese mumakore achangopfuura.Nekuti inogona kuchengetedza zvinhu zvekurongedza kubva pakukanganisa, kunaya, hunyoro uye ngura, uye zvakare kuita kuti zvigadzirwa zvihwine vashandisi neakadhindwa ekunze epakeji, nepo ichinyatso kuratidza mufananidzo wakanaka wemugadziri.Parizvino, vagadziri vekurongedza vanowanda vari kushandisa rakadhindwa shrink firimu kutsiva yechinyakare firimu firimu.Nekuti kudhinda firimu rinodzikira kunogona kuvandudza kutaridzika kwegiredhi yechigadzirwa, kunobatsira kushambadza kwechigadzirwa, uye kunogona kuita ratidziro yakadzama yechiratidzo chechiratidzo mumoyo yevatengi.
