Imiterere y'imikorere y'ibikoresho byo gupfunyika mu buryo butaziguye ni yo ituma ibikoresho byo gupfunyika mu buryo bworoshye bitera imbere. Ibi bikurikira ni intangiriro ngufi ku miterere y'imikorere y'ibikoresho byinshi bikoreshwa mu gupfunyika mu buryo busanzwe.
1. Ibikoresho bikunze gukoreshwa mu gupfunyika: filime ya PE
Ibikoresho bya PE bifunga ubushyuhe byahindutse kuva kuri firime zipfundikiye ku rwego rumwe kugeza kuri firime zisohoka ku rwego rwinshi, ku buryo imiterere y’imiterere y’imbere, hagati n’inyuma ishobora gushushanywa mu buryo butandukanye. Imiterere y’imiterere y’ubwoko butandukanye bwa resine za polyethylene ishobora gutanga ubushyuhe butandukanye bwo kuziba, ubushyuhe butandukanye bwo kuziba, imiterere itandukanye yo kwirinda kwanduza,himbaraga zo gufata neza, ingaruka zo kurwanya static, nibindi, kugira ngo bihuze n'ibisabwa byihariye byo gupfunyika ibicuruzwa hamwe n'ibikoresho bya PE filime bifite imiterere itandukanye y'imikorere.
Mu myaka ya vuba aha, na firime za polyethylene zishingiye ku murongo wa kabiri (BOPE) nazo zarakozwe, zinongera imbaraga zo gukurura za firime za polyethylene kandi zifite imbaraga zo kuziba ubushyuhe bwinshi.
2. Ibikoresho bya filime ya CPP
Ibikoresho bya CPP bikunze gukoreshwa muri BOPP / CPP muri ubu buryo bwo gupfunyika butanyerera, ariko imiterere itandukanye ya CPP resin ishobora no gukorwa mu miterere itandukanye y'imikorere ya firime, nko kunoza ubushyuhe bwo hasi, kurwanya guteka mu bushyuhe bwo hejuru, ubushyuhe bwo hasi bwo kuziba, imbaraga nyinshi zo gutobora, kurwanya ingese, n'indi miterere y'imikorere y'ibikoresho biziba ubushyuhe.
RMu myaka ya vuba aha, inganda zakoze filime ya CPP matte, byongerera ubushobozi bwo kwerekana amashusho y’amasakoshi ya CPP y’urwego rumwe.
3. Ibikoresho bya filime ya BOPP
Filimi yoroheje ikoreshwa cyane mu gupfunyika filime yoroheje ya BOPP na filime ya BOPP matte, hari kandi filime yo gupfunyika ubushyuhe ya BOPP (gupfunyika ubushyuhe ku ruhande rumwe cyangwa ku rundi ruhande), filime ya BOPP pearl.
BOPP irangwa n'imbaraga nyinshi zo gukurura (zikwiriye gusohora amabara menshi), ubushobozi bwiza bwo kubuza amazi guhumeka, ikoreshwa cyane mu gupfunyika urumuri rudahinduka ku buso bw'ibikoresho byacapwe.
Filimi ya BOPP ifite imiterere y’ubushyuhe isa n’impapuro. Filimi ya BOPP ifunga ubushyuhe ishobora gukoreshwa nk'ibikoresho byo gupfunyikamo urwego rumwe, nko gupfunyikamo ipaki y'imbere ya bombo. Filimi ya BOPP y'amasaro ikoreshwa cyane mu gupfunyikamo ice-cream ifunga ubushyuhe, ishobora kuzigama irangi ry'umweru, ifite ubucucike buke, ifite imbaraga zo gufunga hagati ya 2 na 3N/15mm ku buryo isakoshi yoroshye gufungura kugira ngo ikuremo ibirimo.
Byongeye kandi, nka firime ya BOPP irwanya ibihu, firime ya laser ya OPP ya holographic, impapuro za sintetike za PP, firime ya BOPP ishobora kubora n'izindi firime zikora za BOPP nazo zamamaye kandi zikoreshwa mu buryo bwihariye.
4. Ibikoresho bikunze gukoreshwa mu gupfunyika: Ibikoresho bya PET filime
Filimi isanzwe ya 12MICRONS PET ikoreshwa cyane mu gupfunyika ibintu bivanze, imbaraga za mekanike z'ibicuruzwa byayo bya laminated ziri hejuru cyane kurusha ibicuruzwa bya BOPP bifite ibyiciro bibiri (bitoya gato ugereranyije n'ibicuruzwa bya BOPA bifite ibyiciro bibiri), hamwe n'ubushobozi bwo kugabanya umwuka wa ogisijeni bwa firime ya BOPP / PE (CPP) kugira ngo bigabanye inshuro 20 kugeza kuri 30.
Uburyo ibikoresho bya PET birwanya ubushyuhe ni bwiza cyane, kandi bushobora gukorwa ku buryo imifuka myiza ikomera. Hari kandi firime ya PET ishobora gushyuha, firime ya matte PET PET ishobora gushyuha, firime ya matte PET PET, firime ya polyester ifite imigozi myinshi, firime ya PET twist, firime ya PET ya tear ya linear n'ibindi bikoresho bikora neza.
5. Ibikoresho bisanzwe byo gupfunyikamo: filime ya nylon
Filimi ya nylon ikoresha uburyo bwa "biaxial" ikoreshwa cyane mu mifuka ikoresha umwuka ushyushye, ushyushye n'ushyushye kubera imbaraga zayo nyinshi, ubushobozi bwayo bwo gutobora cyane, ubushobozi bwo kurwanya ubushyuhe bwinshi ndetse n'ubushobozi bwo kwirinda umwuka ushyushye.
Udupaki twinshi twa laminated dufite ubushobozi bwo gupima ibiro birenga 1.7kg na two dukoresha imiterere ya BOPA//PE kugira ngo turwanye kugwa neza.
Filimi ya nylon ikoreshwa cyane mu Buyapani mu gupfunyika ibiryo bikonje, ifite ubushobozi bwo kwirinda ubushyuhe buke, igabanya umuvuduko wo kwangirika kw'amasashe mu gihe cyo kubika no gutwara ibiryo mu bushyuhe buke.
6. Ibikoresho bisanzwe byo gupakira: Igipfukisho cya aluminiyumu gikozwe mu cyuma
Gushyira aluminiyumu mu cyuma kiri muri firime (nka PET, BOPP, CPP, PE, PVC, nibindi) ni ubuso bw’ikorwa ry’urwego rw’urukuta rw’aluminiyumu rwinshi, bityo byongera cyane firime ku mwuka w’amazi, ogisijeni, ubushobozi bwo kugabanya urumuri, ari na byo bikoreshwa cyane mu gupakira ibintu bivanze bya VMPET, ibikoresho bya VMCPP.
VMPET yo gusiga amavuta mu byiciro bitatu, VMCPP yo gusiga amavuta mu byiciro bibiri.
Imiterere ya OPP//VMPET//PE ubu imaze gukoreshwa mu mboga zishyirwa mu kabari, ibicuruzwa bya sprouts biri mu ipaki yo kubira mu buryo bw'umwuka. Imiterere ya PE ubu imaze gukoreshwa mu gukamura imboga, ibicuruzwa bya sprouts biri mu ipaki yo kubira mu buryo bw'umwuka, kugira ngo harebwe inenge z'ibicuruzwa bisanzwe bya aluminiyumu, urwego rwa aluminiyumu rworoshye kwimuka, ntirwanye inenge zo kubira, iterambere ry'ibicuruzwa bya VMPET bifite ubwoko bwo hasi bwo gupfuka, mbere na nyuma yo kubira imbaraga zo gukuraho zirenga 1.5N/15mm, kandi urwego rwa aluminiyumu rusa nkaho rudakwirakwira, byongerera imikorere rusange y'umufuka.
7. Ibikoresho bisanzwe byo gupfunyikamo: urupapuro rwa aluminiyumu
Igipfunyika cya aluminiyumu cyo gupfunyikamo cyoroshye muri rusange ni 6.5μm cyangwa 9μUbugari bwa mikroni 12, aluminiyumu ni ibikoresho birinda amazi, amazi yinjira, ogisijeni yinjira, urumuri rusohoka ni "0", ariko mu by'ukuri hari utwenge tw'ingofero muri aluminiyumu kandi ubushobozi bwo gupfunyika bw'ingofero budakomeye, hari ingaruka nyinshi zo gupfunyika imbogamizi ntabwo ari nziza. Ikintu cy'ingenzi mu gukoresha aluminiyumu ni ukwirinda utwenge tw'ingofero mu gihe cyo gutunganya, gupakira no gutwara, bityo bikagabanya ubushobozi bw'ingofero nyazo. Mu myaka ya vuba aha, hari akamenyero ko ibikoresho birinda aluminiyumu gusimburwa n'ibikoresho bihendutse byo gupakira mu bice byabyo bisanzwe bikoreshwa.
8. Ibikoresho bikunze gukoreshwa mu gupfunyika: filime zipfundikiye zifite uburebure bunini
Cyane cyane filime itwikiriwe na PVDC (filime yo gusiga K), filime itwikiriwe na PVA (Filime yo gusiga A).
PVDC ifite ubushobozi bwo kwirinda umwuka wa ogisijeni n'ubushuhe, kandi ifite filime ya PVDC igaragara neza, ikoreshwa muri filime y'ibanze ni BOPP, BOPET, BOPA, CPP, nibindi, ariko ishobora no kuba PE, PVC, cellophane n'izindi filime, mu ipaki ivanze kandi yoroshye muri filime ya KOPP, KPET, KPA ikoreshwa cyane.
9. Ibikoresho bisanzwe byo gupakira: Filimi zirimo uburebure bunini zikoreshwa hamwe
Guhuza ibice byombi ni plastike ebyiri cyangwa nyinshi zitandukanye, binyuze mu bikoresho bibiri cyangwa birenga bibiri, ku buryo ubwoko butandukanye bwa plastike bushonga kandi bugashyirwa muri plastike ku mutwe w’icyuma, gutegura filime zivanze zo mu buryo bwo gushushanya. Filime zivanze zo mu bwoko bwa plastike zivanze, plastike za polyolefin na résine zifatanye zo mu bwoko butatu bw’ibikoresho, résine zivanze ahanini ni PA, EVOH, PVDC, nibindi.
Ibi byavuzwe haruguru ni ibikoresho bisanzwe byo gupfunyika, mu by'ukuri, nibura gukoresha irangi rya okiside, PVC, PS, PEN, impapuro, nibindi, na resin imwe hakurikijwe uburyo butandukanye bwo gutunganya, imiterere itandukanye ishobora gukorwa hakoreshejwe guhindura imiterere itandukanye y'imikorere y'ibikoresho bya filime. Gupfunyika filime zitandukanye, binyuze mu gupfunyika zumye, gupfunyika solvent-free, gupfunyika smulsion n'ubundi buryo bw'ikoranabuhanga buvanze kugira ngo hakorwe ibikoresho bifatika byo gupfunyika bikora neza kugira ngo bihuze n'ibikenewe bitandukanye.ibicuruzwagupfunyika.
