Filimi ya OPP ni ubwoko bwa firimi ya polypropylene, yitwa firimi ya polypropylene ishingiye kuri co-extruded oriented (OPP) kuko inzira yo kuyikora ari ugusohora ibintu mu byiciro byinshi. Iyo hari inzira yo kurambura ibintu mu buryo bubiri, yitwa firimi ya polypropylene ishingiye kuri bi-directional (BOPP). Indi yitwa firimi ya polypropylene ishingiye kuri cast (CPP) bitandukanye n'inzira yo gusohora ibintu mu buryo bubiri. Filimi eshatu zitandukanye mu miterere yazo n'imikoreshereze yazo.
I. Imikoreshereze y'ingenzi ya filime ya OPP
OPP: polypropylene ishingiye ku murongo (filime), polypropylene ishingiye ku murongo, ni ubwoko bumwe bwa polypropylene.
Ibicuruzwa by'ingenzi bikozwe muri OPP:
1, kaseti ya OPP: Filime ya polypropylene nk'umusemburo, ifite imbaraga zo gukurura cyane, yoroheje, idahumanya, nta buryohe, nta bidukikije biyibangamira, ikoreshwa mu buryo butandukanye n'izindi nyungu
2, ibirango bya OPP:Kuko isoko rigizwe n'ibicuruzwa byuzuye kandi bihuye buri munsi, imiterere ni yo yose, igitekerezo cya mbere kigena imyitwarire y'umuguzi mu kugura. Shampoo, gel yo kwiyuhagira, isabune n'ibindi bicuruzwa bikoreshwa mu bwiherero bushyushye kandi butose no mu gikoni, ibisabwa ku kirango kugira ngo bihangane n'ubushuhe kandi ntibigwe, kandi ubushobozi bwabyo bwo kudasohoka bugomba guhuzwa n'icupa, mu gihe amacupa abonerana kugira ngo kole n'ibikoresho byo kwandikaho bigaragare neza.
Ibirango bya OPP ugereranyije n'ibirango by'impapuro, bifite ubwisanzure, imbaraga nyinshi, ubushuhe, bitoroshye kugwa n'ibindi byiza, nubwo ikiguzi cyongerwa, ariko bishobora kubona ikimenyetso cyiza cyane n'ingaruka nziza zo gukoresha. Ariko bishobora kubona ikimenyetso cyiza cyane n'ingaruka nziza zo gukoresha. Bitewe n'iterambere ry'ikoranabuhanga ryo gucapa mu gihugu, ikoranabuhanga ryo gusiga, gukora ibirango bya filime byifata neza no gucapa ibirango bya filime ntibikiri ikibazo, birashoboka ko ikoreshwa ry'ibirango bya OPP mu gihugu rizakomeza kwiyongera.
Kubera ko ikirango ubwacyo ari PP, gishobora guhuzwa neza n'ubuso bw'ibikoresho bya PP / PE, imyitozo yagaragaje ko filime ya OPP ubu ari yo ikoreshwa neza mu gushyira ibirango mu ibumba, inganda z'ibiribwa n'ibinyabutabire bya buri munsi mu Burayi zagiye zikoreshwa cyane, kandi buhoro buhoro zikwirakwira mu ngo, hari abakoresha benshi batangiye kwita ku buryo bwo gushyira ibirango mu ibumba cyangwa gukoresha.
Icya kabiri, intego nyamukuru ya filime ya BOPP
BOPP: Filimi ya polypropylene ishingiye ku ruhande rumwe, na yo ikaba ari ubwoko bumwe bwa polypropylene.
Filime za BOPP zikunze gukoreshwa zirimo:
● Filime ya polypropylene ishingiye ku miterere ibiri rusange,
● Filime ya polypropylene ifite imiterere ibiri ifunze neza,
● agapapuro ko gupfunyikamo itabi,
● Filime ya polypropylene pearlescent ifite imiterere ibiri,
● Filime ya polypropylene ifite icyuma ishingiye ku miterere ibiri,
● Filime idakora neza n'ibindi.
Imikoreshereze y'ingenzi ya filime zitandukanye ni iyi ikurikira:
1. Filime isanzwe ya BOPP
Ikoreshwa cyane cyane mu gucapa, gukora imifuka, nk'ikaseti ifatana n'ibindi bikoresho bivanze.
2, Filime yo kuziba ubushyuhe ya BOPP
Ikoreshwa cyane cyane mu gucapa, gukora amasakoshi n'ibindi.
3, agapaki k'itabi rya BOPP
Ikoreshwa: Ikoreshwa mu gupfunyika itabi ryihuse cyane.
4, Filime ya BOPP ifite ubwiza
Ikoreshwa mu gupfunyika ibiryo n'ibicuruzwa byo mu rugo nyuma yo gucapa.
5, Filime ya BOPP y'icyuma
Ikoreshwa mu gufunga ibyuma mu buryo bwa vacuum metallization, imirasire, substrate irwanya ibihimbano, no gupakira ibiryo.
6, Filime ya BOPP matte
Ikoreshwa mu gusabune, ibiryo, itabi, amavuta yo kwisiga, imiti n'andi masanduku yo gupfunyikamo.
7, Filime yo kurwanya ibihu ya BOPP
Ikoreshwa mu gupfunyika imboga, imbuto, sushi, indabyo n'ibindi.
Filimi ya BOPP ni ibikoresho by'ingenzi cyane byo gupfunyikamo, kandi bikoreshwa cyane.
Filimi ya BOPP nta ibara, nta mpumuro, nta buryohe, nta burozi, kandi ifite imbaraga nyinshi zo gukurura, imbaraga zo gukubita, gukomera, gukomera no gukorera mu mucyo.
Ingufu zo hejuru ya firime ya BOPP ni nke, kole cyangwa icapwa mbere yo kuvurwa na corona. Ariko, firime ya BOPP nyuma yo kuvurwa na corona, ifite ubushobozi bwo gucapa neza, ishobora gucapwa amabara kandi ikagira isura nziza, bityo ikaba ikoreshwa cyane nk'ibikoresho bya firime ivanze.
Filimi ya BOPP ifite kandi inenge, nko koroshya kwegeranya amashanyarazi adahindagurika, nta gufunga ubushyuhe n'ibindi. Mu mushinga wo gukora wihuta cyane, filime ya BOPP ikunze kurwara amashanyarazi adahindagurika, bisaba gushyiraho icyuma gikuraho amashanyarazi adahindagurika.
Kugira ngo haboneke firime ya BOPP ifunga ubushyuhe, firime ya BOPP ishobora gusigwa na kole ya resin ifunga ubushyuhe, nka latex ya PVDC, latex ya EVA, nibindi. Ishobora kandi gusigwa na kole ya solvent, ariko kandi uburyo bwo gusiga cyangwa gusiga hamwe na kole ya BOPP bushobora gukoreshwa mu gukora firime ya BOPP ifunga ubushyuhe. Iyi firime ikoreshwa cyane mu gupfunyika imigati, imyenda, inkweto n'amasogisi, ndetse no mu gupfunyika itabi, ibitabo.
Gutangira gukoresha firime ya BOPP kugira ngo imbaraga z'amarira zitere nyuma yo kurambura byariyongereye, ariko imbaraga z'amarira za kabiri ni nke cyane, bityo firime ya BOPP ntishobora gusigara ku mpande zombi z'inyuma y'urukuta, bitabaye ibyo firime ya BOPP yoroshye kuyicapa, ikayitera gucika.
BOPP ipfundikiye kaseti ishobora gukorwa kugira ngo ifunze kaseti yo mu gasanduku, ni ko igipimo cya BOPP cya BOPP gipfundikiye kaseti gishobora gukora kaseti yo gufunga, ni uburyo BOPP ikoreshwa ku isoko rinini.
Filimi za BOPP zishobora gukorwa hakoreshejwe uburyo bwa tube film cyangwa uburyo bwa flat film. Imiterere ya filime za BOPP ziboneka hakoreshejwe uburyo butandukanye bwo kuzitunganya iratandukanye. Filimi ya BOPP ikorwa hakoreshejwe uburyo bwa flat film bitewe n'igipimo kinini cyo gukurura (kugeza kuri 8-10), bityo imbaraga zikaba ziruta uburyo bwa tube film, ubunini bwa filime nabwo ni bwiza kurushaho.
Kugira ngo imikorere myiza muri rusange irusheho kuba myiza, mu ikoreshwa ry’iyi nzira ikunze gukoreshwa mu gukora uburyo bwa multilayer composite. BOPP ishobora kuvangwa n’ibikoresho bitandukanye kugira ngo ihuze n’ibikenewe mu buryo bwihariye. Nka BOPP ishobora kuvangwa na LDPE (CPP), PE, PT, PO, PVA, nibindi kugira ngo ibone urwego rwo hejuru rw’imyotsi irinda umwuka, imbogamizi z’ubushuhe, ubushyuhe bwinshi n’ubukonje, ubwirinzi bw’ibiryo mu guteka no kwirinda amavuta, ibyuma bitandukanye bishobora gushyirwa ku biribwa bifite amavuta.
Icya gatatu, intego nyamukuru ya filime ya CPP
CPP: ubwisanzure bwiza, ubwiza bwinshi, gukomera neza, imbogamizi nziza z'ubushuhe, ubwihanganira ubushyuhe bwiza, kuziba byoroshye gushyushya n'ibindi.
Filimi ya CPP nyuma yo gucapa, gukora amasakoshi, ikwiriye: imyenda, amasakoshi yo kuboha n'indabyo; inyandiko na alubumu filime; gupfunyika ibiryo; no gupfunyika ibyuma bikingira n'ibyuma bikozwe mu cyuma.
Nanone, bishobora gukoreshwa harimo: gupfunyika ibiryo, gupfunyika ibiryo mu byuma bivanze n'amafishi, gupfunyika imiti (udufuka two kuyishyiramo), gusimbuza PVC mu mafoto, mu mpapuro n'inyandiko, impapuro zikozwe mu buryo bwa sintetike, kaseti zo kwifata, ibikoresho byo gufata amakarita y'ubucuruzi, udupfunyika tw'impeta n'udupfunyika two guhagarara.
CPP ifite ubushobozi bwo kurwanya ubushyuhe bwinshi.
Kubera ko aho PP yoroshya ibintu ari hafi 140°C, ubu bwoko bwa firime bushobora gukoreshwa ahantu nko mu byuzuza ibintu bishyushye, mu masakoshi ashyushya ndetse no mu gupfunyikamo ibintu bidasembuye.
Hamwe no kurwanya aside, alkali n'amavuta meza, bituma iba ibikoresho bikundwa cyane nko mu gupfunyikamo imigati cyangwa ibikoresho bya laminated.
Umutekano wayo mu gukora ku biribwa, imikorere yayo myiza yo kwerekana, ntabwo bizagira ingaruka ku buryohe bw'ibiryo biri imbere, kandi ishobora guhitamo ubwoko butandukanye bwa resin kugira ngo ibone imiterere wifuza.
