Udupaki twa Zipu y'ibiribwa, udupaki twa Zipu y'imashini ya Plastiki ifite udupaki dutatu tw'imashini ya aluminiyumu ifite udupaki duto two ku ruhande rumwe

Umufuka w’ipfundikizo ufite impande eshatu ushobora gufatwa nk’ubwoko bw’umufuka w’ipfundikizo ufite impande eshatu. Hashingiwe ku mufuka w’ipfundikizo ufite impande eshatu, umufuka wifunga ku munwa w’umufuka ushyirwa ku munwa. Umufuka nk’uwo ushobora gufungurwa no gufungwa inshuro nyinshi kandi ushobora gukoreshwa inshuro nyinshi. Ubwo bwoko bw’ipakira bukwiriye cyane iyo umufuka ufite ingano nini gato, kandi ibicuruzwa biri mu mufuka ntibishobora gukoreshwa icyarimwe.
Urugero, imbuto zumye, imbuto z'ubunyobwa, ibirungo byumye, ibiryo by'ifu, n'ibiribwa bitaribwa icyarimwe bikunze gukoreshwa mu mifuka ya pulasitiki irimo zipu cyangwa imifuka ya pulasitiki ifite kole. Imifuka yo gupfunyikamo ibiryo ifite zipu n'imifuka ya pulasitiki ifite zipu ni nk'imifuka ya pulasitiki. Iyo umufuka ufunguwe, ushobora gupfunyika kabiri. Nubwo udashobora kugera ku ngaruka zo gupfunyikamo bwa mbere, ushobora gukoreshwa nk'ikintu kirinda ubushuhe bwa buri munsi kandi kirinda umukungugu mu gihe gito. Biracyashoboka.
Umufuka wo gushyiramo zipu ugizwe n'impande eshatu ushobora gukoreshwa n'abaguzi ku rugero runini, kandi uhenze gato ugereranyije n'umufuka wo gushyiramo zipu ugizwe n'impande eshatu, ariko ukunzwe cyane n'abaturage kubera ko woroshye kuwukoresha no koroshya. Hariho kandi amahitamo menshi iyo bigeze ku bijyanye no guhindura imifuka.
