Gupfunyika si ikintu cyo gutwaramo ibicuruzwa gusa, ahubwo ni n'uburyo bwo gushishikariza no kuyobora ikoreshwa ryabyo ndetse no kugaragaza agaciro k'ikirango.

Ibikoresho byo gupfunyika bivanze ni ibikoresho byo gupfunyika bigizwe n'ibikoresho bibiri cyangwa byinshi bitandukanye. Hari ubwoko bwinshi bw'ibikoresho byo gupfunyika bivanze, kandi buri gikoresho gifite imiterere yacyo n'uburyo gikoreshwa. Ibi bikurikira bizagaragaza bimwe mu bikoresho bisanzwe byo gupfunyika bivanze.

1. Ibikoresho bya aluminiyumu-plastiki byashyizwemo laminated (AL-PE): Ibikoresho bya aluminiyumu-plastiki bigizwe n'urupapuro rwa aluminiyumu na filime ya pulasitiki kandi bikunze gukoreshwa mu gupfunyika ibiryo. Urupapuro rwa aluminiyumu rufite ubushobozi bwo gukingira ubushyuhe, rurinda ubushuhe kandi rurwanya ogisijeni, mu gihe filime ya pulasitiki yoroshye kandi irinda gucika, bigatuma filime ikomera.

2. Ibikoresho by’impapuro-plastiki (P-PE): Ibikoresho by’impapuro-plastiki bigizwe n’impapuro n’ifiriti kandi bikunze gukoreshwa mu gupfunyika ibintu by’ingenzi bya buri munsi, ibiribwa n’imiti. Impapuro zifite ubushobozi bwo guhangana n’umuvuduko mwiza kandi ntizingiza ibidukikije, mu gihe ifiriti ya pulasitiki ishobora gutanga ubushuhe n’umwuka.

3. Ibikoresho bivanze bidaboshye (NW-PE): Ibikoresho bivanze bidaboshye bigizwe n'imyenda idafite ubudodo n'ifiriti ya pulasitiki kandi bikunze gukoreshwa mu bikoresho byo mu rugo, imyenda n'ibindi. Imyenda idafite ubudodo ifite ubushobozi bwo guhumeka neza no kwinjiza amazi, mu gihe imyenda ya pulasitiki ishobora gutanga ubushobozi bwo kwirinda amazi no kwirinda ivumbi.

4. Ibikoresho bivanze bya PE, PET, OPP: Ibi bikoresho bivanze bikunze gukoreshwa mu gupfunyika ibiryo, ibinyobwa n'amavuta yo kwisiga. PE (polyethylene), PET (polyester film) na OPP (polypropylene film) ni ibikoresho bisanzwe bya pulasitiki. Bifite ubwisanzure bwiza kandi ntibishobora kwinjira mu mubiri kandi bishobora kurinda neza gupfunyika.

5. Ibikoresho bya aluminiyumu, PET, PE: Ibi bikoresho bivanze bikunze gukoreshwa mu gupfunyika imiti, amavuta yo kwisiga n'ibiribwa bikonje. Ibikoresho bya aluminiyumu bifite ubushobozi bwo kurwanya ogisijeni no kubungabunga ubushyuhe, PET itanga imbaraga n'ubukonje runaka, naho PE itanga ubushobozi bwo kwirinda ubushuhe no kudapfa amazi.

Muri make, hari ubwoko bwinshi bw'ibikoresho byo gupfunyikamo ibintu bivanze, kandi uburyo butandukanye bwo gupfunyikamo ibintu bushobora gutanga imikorere itandukanye bitewe n'ibikenewe bitandukanye byo gupfunyikamo. Ibi bikoresho bivanze bigira uruhare runini mu nganda zo gupfunyikamo ibintu, bitanga ibisubizo byiza byo kubungabunga, kurinda no gutwara ibicuruzwa.

Ibikoresho byo gupfunyika birimo gukoreshwa cyane mu nganda zipfunyika. Ibikoresho byo gupfunyika bifite ibyiza byinshi, nko kwirinda ubushuhe, kwirinda ogisijeni, kubungabunga ubushyuhe, nibindi, bityo bikundwa n'abaguzi n'ibigo bikora. Mu iterambere ritaha, ibikoresho byo gupfunyika bigizwe n'ibice bigizwe n'ibice bigizwe n'ibice binini bizakomeza guhura n'amahirwe mashya n'imbogamizi.

Ikora neza kandi itangiza ibidukikije

Gukoresha ibikoresho bya pulasitiki bizatera imyanda myinshi, bigatera umwanda ukomeye ku bidukikije. Ibikoresho byo gupfunyika bivanze bikora neza cyane kandi birengera ibidukikije, bigabanya neza ikorwa ry’imyanda kandi bikagabanya ingaruka zayo ku bidukikije. Mu gihe kizaza, ibikoresho byo gupfunyika bivanze bizibanda cyane ku kunoza imikorere yo kurengera ibidukikije kandi biteze imbere ibikoresho byo gupfunyika bivanze bishobora kwangirika kugira ngo bihuze n’ibyo abantu bakeneye byo gupfunyika bivanze.

Imikorere yo gupfunyika ibintu bivanze

Ibikoresho gakondo byo gupfunyika bishobora kugira uruhare rworoshye rwo kurinda, mu gihe ibikoresho bivanze byo gupfunyika bishobora kongeramo urwego rutandukanye rw'imikorere uko bikenewe, nko kwirinda amazi, kwirinda ubushuhe, kurwanya ogisijeni, nibindi, kugira ngo birinde neza ireme n'umutekano w'ibintu bipfunyitse. Imirimo mishya, nko kurwanya bagiteri n'ubuvuzi, izakomeza gutezwa imbere kugira ngo ihuze n'ibyo abantu bakeneye mu mirimo yo gupfunyika.

Iterambere ry'amapaki akozwe mu buryo bwihariye

Kubera ko ibyo abaguzi bakeneye bikwirakwira mu buryo butandukanye, gupakira nabyo bigomba kuba byihariye kandi bigatandukana. Ibikoresho byo gupakira bishobora guhindurwa hakurikijwe imiterere n'ibyo ibicuruzwa bitandukanye bikenera, nko gucapa imiterere itandukanye, amabara, n'ibindi. Witondere cyane imiterere yihariye kugira ngo wongere ipiganwa ry'ibicuruzwa n'isoko.

Mu iterambere ry’ejo hazaza, ibikoresho byo gupfunyika bifite laminate byoroshye bizatera imbere mu buryo bunoze, kurengera ibidukikije, imikorere, ubwenge no guhindura isura y’umuntu ku giti cye. Iyi miterere y’iterambere izakomeza kongera ipiganwa ku isoko n’agaciro k’ibikoresho byo gupfunyika bifite laminate.

Nk'igice cy'ingenzi cy'inganda zipakira, ibikoresho bipakiye bifite laminated bizagira uruhare runini mu iterambere ry'ejo hazaza kandi biteze imbere iterambere n'udushya mu nganda zose zipakira.
