Hari ubwoko bwinshi bw'udufuka two gupfunyikamo ibiryo dukoreshwa mu gupfunyika ibiryo, kandi dufite imikorere n'imiterere yatwo yihariye. Uyu munsi turaganira ku bumenyi busanzwe bukoreshwa ku dufuka two gupfunyika ibiryo kugira ngo ubashe kubikoresha. None se udufuka two gupfunyikamo ibiryo ni iki? Udufuka two gupfunyikamo ibiryo muri rusange tuvuga pulasitiki isa n'impapuro zifite ubugari buri munsi ya mm 0.25 nk'udupapuro, kandi udufuka tworoshye dukozwe muri pulasitiki dukoreshwa cyane mu nganda z'ibiribwa. Hariho ubwoko butandukanye bw'udufuka two gupfunyikamo ibiryo. Dufite isura, tworoshye, dufite ubushobozi bwo kwirinda amazi, dufite ubushobozi bwo kwirinda ubushuhe n'imyuka mibi, dufite imbaraga nziza za mekanike, dufite ubushobozi bwo kwirinda ibinyabutabire buhamye, dufite ubushobozi bwo kwirinda amavuta, tworoshye gucapa neza, kandi dushobora gupfunyika mu dufuka dushyushye. Byongeye kandi, udufuka tworoshye dukoreshwa mu gupfunyikamo ibiryo dukunze gukoreshwa dugizwe n'udupande tubiri cyangwa turenze twa firime zitandukanye, muri rusange dushobora kugabanywamo urwego rwo hanze, urwego rwo hagati n'urwego rw'imbere bitewe n'aho duherereye.
Ni ibihe bisabwa kugira ngo buri cyiciro cy’amafirime yo gupfunyika ibiryo akoreshwa cyane gikoreshwe? Mbere na mbere, firime yo hanze muri rusange icapwa, ntishobora gushwaragurika, kandi ntishobora kwangirika. Ibikoresho bikunze gukoreshwa birimo OPA, PET, OPP, na firime zitwikiriye. Filime yo hagati muri rusange ifite imirimo nko gukingira, gutwikira urumuri, no kurinda umubiri. Ibikoresho bikunze gukoreshwa birimo BOPA, PVDC, EVOH, PVA, PEN, MXD6, VMPET, AL, nibindi. Hanyuma hari firime y'imbere, muri rusange ifite imirimo yo gukingira, gufunga, no kurwanya ibyuma. Ibikoresho bikunze gukoreshwa ni CPP, PE, nibindi. Byongeye kandi, bimwe mu bikoresho bifite urwego rwo hanze n'urwego rwo hagati. Urugero, BOPA ishobora gukoreshwa nk'urwego rwo hanze rwo gucapa, kandi ishobora no gukoreshwa nk'urwego rwo hagati kugira ngo igire uruhare runaka rwo kurinda umubiri no kurinda umubiri.
Imiterere ya firime yo gupfunyika ibiryo ikunze gukoreshwa, muri rusange, ibikoresho byo hanze bigomba kuba bifite ubushobozi bwo kwirinda gushwara, kurwanya gutobora, kurinda imirasire ya UV, kurwanya urumuri, kurwanya amavuta, kurwanya ibintu by’umwimerere, kurwanya ubushyuhe n’ubukonje, kurwanya gucika kw’imihangayiko, gucapa, kudahinduka kw’ubushyuhe, impumuro nke, nta mpumuro mbi, nta burozi, birabagirana, bibonerana, bifite igicucu n’uruhererekane rw’ibintu; ibikoresho byo hagati muri rusange bigomba kuba bifite ubushobozi bwo kurwanya ingaruka, kudahinduka kw’imikoreshereze, kudahinduka kw’imikoreshereze, kudahinduka kw’imikoreshereze, kudahinduka kw’imikoreshereze y’imyuka ... ibiri, uburyohe buke, impumuro nke, nta burozi, bidahinduka, bidahinduka, bidahinduka n’ibindi; hanyuma ibikoresho byo mu cyiciro cy’imbere, uretse bimwe mu bintu bisanzwe byo mu cyiciro cy’inyuma n’icyo hagati, bifite ubushobozi bwabyo bwihariye, bugomba kuba bufite ubushobozi bwo kugumana impumuro nziza, kudahinduka kw’imikoreshereze y’imyuka mike no kudasohoka. Iterambere ry’amashashi yo gupfunyika ibiryo ubu ni iri rikurikira:
1. Imifuka yo gupfunyikamo ibiryo ikozwe mu bikoresho bitangiza ibidukikije.
2. Kugira ngo tugabanye ikiguzi kandi tuzigame umutungo, imifuka yo gupakira ibiryo iragenda irushaho kuba mito.
3. Imifuka yo gupakira ibiryo irimo gutera imbere mu rwego rwo gukora imirimo yihariye. Ibikoresho bivanze n’imbogamizi nyinshi bizakomeza kongera ubushobozi bw’isoko. Mu gihe kiri imbere, filime zifite imbogamizi nyinshi zifite ibyiza byo gutunganya byoroshye, umwuka mwinshi wa ogisijeni n’umwuka w’amazi, hamwe n’igihe cyo kubika ibiryo kizaba ikintu cy’ingenzi mu gupakira ibiryo mu maduka manini mu gihe kizaza.
