Icupa rya pulasitiki rikozwe mu buryo bwihariye rigabanya ubushyuhe rya PVC ripfundikiye amaboko, ikimenyetso cyo gufunga amacupa y'ibinyobwa

Ikimenyetso cya firime ishobora gushwanyagurika ni ikimenyetso cya firime cyanditse ku gipfundikizo cya pulasitiki cyangwa umuyoboro wa pulasitiki gifite wino yihariye. Mu gihe cyo gushyira ikimenyetso, iyo gishyushye (hafi 70°C), ikimenyetso gishobora gushwanyagurika kizakurikira vuba imiterere y'inyuma y'igikoresho. Ikimenyetso gishobora gushwanyagurika, hafi y'ubuso bw'igikoresho, ikimenyetso cya firime ishobora gushwanyagurika cyane cyane kirimo ibirango by'amaboko yo gushwanyagurika n'ibirango byo gupfunyika.

Ikimenyetso gishobora gushwanyagurika, hafi y'ubuso bw'igikoresho, ikimenyetso cya firime ishobora gushwanyagurika cyane cyane kirimo ibirango by'amaboko yo gushwanyagurika n'ibirango byo gupfunyika.
Ikimenyetso cy'amaboko yo gushwanyagurika ni ikirango cy'umuzenguruko gikozwe muri firime ishobora gushwanyagurika nk'ibikoresho by'ibanze nyuma yo gucapa. Gifite imiterere yo gukoreshwa neza kandi gikwiriye cyane ibikoresho bifite imiterere yihariye. Ibirango by'amaboko yo gushwanyagurika muri rusange bisaba gukoresha ibikoresho byihariye byo gushyiramo ikirango kugira ngo ushyiremo ikirango cyacapwe ku gikoresho. Ubwa mbere, ibikoresho byo gushyiramo ikirango bifungura ikirango cy'amaboko yo gushwanyagurika gifunze, rimwe na rimwe gishobora gukubitwa; hanyuma, ikirango cy'amaboko gicibwa ku bunini bukwiye hanyuma kigashyirwa ku gikoresho; hanyuma hagakoreshwa ubushyuhe hakoreshejwe umwuka ushyushye, infrared cyangwa imiyoboro y'umwuka ushyushye, kugira ngo ikirango cy'amaboko gifatanye neza n'ubuso bw'igikoresho.
Bitewe n'uko filime ubwayo igaragara cyane, ikirango gifite ibara ryiza kandi gitanga urumuri rwiza. Ariko, kubera ko kigomba kugabanuka mu gihe cyo gukoreshwa, hari ikibazo cyo guhinduka kw'ishusho, cyane cyane ku bicuruzwa byacapwe bifite ibirango bya barcode. Kigomba kunyura mu buryo buhamye bwo kugenzura imiterere y'ishusho no gucapa, bitabaye ibyo ubwiza bwa barcode ntibuzaba bwemewe nyuma y'uko igishushanyo mbonera kidahinduka. Ibirango byo gupfunyika bishobora gukoreshwa hakoreshejwe ibikoresho bisanzwe byo gushyiramo ibirango, bisaba gukoresha kole n'ubushyuhe bwinshi. Mu gihe cyo kugabanya, kubera ko kole iri ku gice gifatanye cya filime izatera stress, ni byiza gukoresha kole ishyushye ishongesha.
Ikirango cya firime igabanya ubushyuhe ni kimwe mu bigize isoko ry’ibirango, ririmo kwiyongera cyane, kandi isoko ryacyo ririmo kwaguka. Ahantu heza mu nganda zicapa ibirango. Biteganyijwe ko isoko rya firime igabanya ubushyuhe mu gihugu rizakura ku kigero kirenga 20% mu myaka itanu iri imbere.
Inganda z'ibiribwa ni isoko rinini cyane ryo gupakira ibintu bishyushye. Filimi ishyushye ikoreshwa cyane mu gupakira ibiryo byihuse bitandukanye, ibiryo bishyushye bya aside lactic, ibinyobwa, ibiryo bito, amacupa y'inzoga, divayi zitandukanye, ibikomoka ku buhinzi n'ibiribwa byo ku ruhande, ibiryo byumye, ibikomoka ku bimera, nibindi. Abakiriya b'isoko ry'ibirango bya shrink film ni ibigo binini bicuruza ibintu byihuta, nka Procter & Gamble, Unilever, Shanghai Jahwa, nibindi, ibicuruzwa byabo biri mu byiciro binini kandi bisaba gucapwa mu gihe kirekire. Ishoramari rya mbere ryo gucapa gravure ni rinini, ariko kuramba cyane kwa gravure plate n'igiciro gito bituma iba amahitamo ya mbere yo gucapa shrink film. Byongeye kandi, igice cy'ishusho kiri ku rupapuro rwo gucapa ni gito, bityo haboneka urwego rw'iwino ikomeye, amabara meza n'ibice byinshi.
Mu guteza imbere icapiro rya flexographic, amwe mu mafilimi yo gushwanyagurika nayo acapishwa hakoreshejwe flexographic, cyane cyane ibikoresho bya PE bidashobora kwihanganira ubukana bwinshi, kandi inyinshi muri zo zikoresha imashini zo gucapira flexographic zo mu bwoko bwa CI. Mu rwego rw'ibiribwa bitari ibyo kurya, ikoreshwa ry'amafilimi yo gushwanyagurika mu bushyuhe naryo ririyongera umunsi ku wundi, nko kwandika amafishi n'imipfundikizo y'amacupa, ibifuniko, amavuta yo kwisiga, imiti, ibikoresho bya shimi bya buri munsi, ibikoresho byo mu gikoni, ibikoresho bya buri munsi, nibindi. Muri icyo gihe, yakoreshejwe cyane mu bicuruzwa bya ceramic, amaseti y'icyayi, ibice bya mekanike, ibikoresho by'ubwubatsi n'ibikoresho byo gutwara.
