Umufuka w'umufuka w'umupfundikizo wacapwe ku buryo bwihariye, uhagaze neza, ukoreshwa mu gupakira ibinyobwa bya pulasitiki bishobora kongera gukoreshwa, upakiye umufuka w'umufuka w'umupfundikizo ufite umufuka w'umutobe w'amazi.

Umufuka w'umunwa uhagaze ni mu buryo bushya bwo gupakira, kandi inyungu yawo ikomeye kuruta imiterere isanzwe yo gupakira ni uburyo bwo gutwara; umufuka w'umunwa wishingikirizaho ushobora gushyirwa mu gikapu cyangwa mu mufuka, kandi ushobora kugabanuka mu bunini uko ibirimo bigabanuka, byoroshye gutwara. Ufite ibyiza byo kunoza ireme ry'ibicuruzwa, wongera ubushobozi bwo kureba mu gikapu, woroshye gutwara, woroshye gukoresha, ubikwa neza kandi ufunga neza. Umufuka w'umunwa wishingikirizaho ukozwe muri laminated hakoreshejwe imiterere ya PET/foil/PET/PE, kandi ushobora kandi kugira imiterere ibiri, imiterere itatu n'ibindi bikoresho by'ibindi bipimo. Biterwa n'ibicuruzwa bitandukanye bigomba gupakirwa. Urukuta rurinda umwuka rushobora kongerwaho uko bikenewe kugira ngo ugabanye ubushobozi bwo kwinjira mu kirere, wongere igihe cyo gukoresha umwuka.

Gupfunyika ibinyobwa bidasembuye ku isoko ahanini biri mu macupa ya PET, amasashe y'impapuro za aluminiyumu, n'amacupa. Muri iki gihe, hamwe n'irushanwa rigaragara cyane ryo guhuza ibintu, kunoza uburyo bwo gupfunyika nta gushidikanya ko ari bumwe mu buryo bukomeye bwo gupiganwa butandukanye. Isashe yishingikiriza ihuza gupfunyika kenshi kw'amacupa ya PET n'imideli y'amasashe y'impapuro za aluminiyumu. Muri icyo gihe, ifite kandi ibyiza bitagereranywa byo gupfunyika ibinyobwa gakondo mu mikorere yo gucapa. Bitewe n'imiterere y'ibanze y'isashe yishingikiriza, agace k'isashe y'umunwa kanini cyane kuruta icupa rya PET, kandi ni keza kuruta ipaki nk'isashe idashobora kwihanganira. Birumvikana ko kubera ko isashe y'umunwa iri mu cyiciro cy'udupfunyika tworoshye, ntabwo ikwiriye gupfunyika ibinyobwa birimo karubone, ariko ifite ibyiza byihariye mu mitobe y'imbuto, ibikomoka ku mata, ibinyobwa by'ubuzima, ibiryo bya jelly, nibindi.

Ipaki y'umufuka wo guhagarara ikoreshwa cyane cyane mu binyobwa by'umutobe w'imbuto, ibinyobwa bya siporo, amazi yo kunywa ari mu macupa, jeli ibasha kunyurwamo, ibirungo n'ibindi bicuruzwa. Igenda yiyongera buhoro buhoro.

Agafuka gafata umunwa gafasha umuntu kwisukira cyangwa kunyunyuza ibirimo, kandi gashobora kongera gufungwa no gufungurwa icyarimwe, ibyo bikaba bishobora gufatwa nk'uruvange rw'agafuka gafasha umuntu kwisukira n'umunwa usanzwe w'icupa. Ubu bwoko bw'agafuka gafasha umuntu kwisukira muri rusange gakoreshwa mu gupfunyika ibintu by'ingenzi bya buri munsi, kandi gakoreshwa mu gushyiramo ibintu by'amazi, ibinyobwa bya colloidal n'ibikomeye nk'ibinyobwa, gel zo kwiyuhagira, shampoo, ketchup, amavuta yo kurya, na jeli.
