ishashi ya pulasitiki ifite zipu ifunze neza ifite idirishya

Agafuka gahagaze ni ubwoko bushya bwo gupfunyika, gafite ibyiza byo kunoza ireme ry'ibicuruzwa, kongerera ubushobozi bwo kureba neza amashelufu, koroshye gutwara, kakaguma gashya kandi gafunga.

Agafuka gahagarara muri rusange gakozwe mu buryo bwa PET/PE, kandi gashobora no kugira ibikoresho by’urwego rubiri, urundi rw’urwego rutatu n’ibindi. Bitewe n’igicuruzwa kigomba gupfunyikwa, urundi rwego rurinda umwuka rushobora kongerwamo kugira ngo bigabanye kwinjira kwa ogisijeni no kongera igihe ibicuruzwa bimara.

Agapfunyika gafite zipu gashobora kongera gufungwa no kongera gufungurwa. Kubera ko zipu ifunze kandi ifite uburyo bwo gufunga neza, ibi birakwiriye gupakira ibintu bito n'ibintu bihindagurika. Dukurikije uburyo butandukanye bwo gufunga impande, gagabanyijemo ibice bine byo gufunga impande n'ibice bitatu byo gufunga impande. Mu gihe ukoresha, ni ngombwa gukata umugozi usanzwe wo ku ruhande, hanyuma ugakoresha zipu kugira ngo ubone uburyo bwo gufunga no gufungura inshuro nyinshi. Ubu buvumbuzi bukemura ibibazo byo kudafunga impande no kuzamuka nabi kw'izipu no kuyitwara nabi. Hariho kandi impande eshatu z'inyuguti zifunze neza hakoreshejwe zipu, muri rusange zikoreshwa mu gufata ibintu byoroshye. Udupfunyika twigenga dufite zipu akenshi dukoreshwa mu gupakira ibintu bimwe na bimwe byoroheje, nka bombo, biscuits, jellies, nibindi, ariko udupfunyika twigenga dufite impande enye na two dushobora gukoreshwa ku bicuruzwa biremereye nk'umuceri n'ibikomoka ku injangwe.

Muri icyo gihe, hakurikijwe ibyo gupfunyika bikenewe, imiterere mishya y'udufuka duhagaze tw'imiterere itandukanye ikorwa hashingiwe ku muco gakondo, nko gushushanya hasi, imiterere y'udupira, n'ibindi, bishobora gufasha ibicuruzwa kugaragara neza. Ku gikoresho bishobora no kongera cyane ingaruka z'ikirango.
