Isesengura ku mpinduka mu ikoreshwa ry'ibiyobyabwenge mu gihe kiri imbere.

Muri iki gihe, ikoreshwa ry'ingenzi ryapolyethylenemu gihugu cyanjye harimo filime, injection molding, umuyoboro, ububobere, insinga zishushanyije, insinga, metallocene, coating n'izindi moko y'ingenzi.

Icya mbere gifatwa n’ingufu nyinshi, igice kinini cy’ikoreshwa ry’ibicuruzwa biri inyuma ni filime. Ku nganda zikora filime, igice cy’ingenzi ni filime z’ubuhinzi, filime z’inganda n’ibicuruzwa bipfunyika. Ariko, mu myaka ya vuba aha, ibintu nko kugabanya imifuka ya pulasitiki no kugabanuka gukabije kw’ibikenewe bitewe n’icyorezo byagiye bibabangamira kenshi, kandi bahura n’ikibazo giteye isoni. Ubusabe bw’ibicuruzwa bisanzwe bya filime za pulasitiki zizasimburwa buhoro buhoro no gukurura pulasitiki zishobora kwangirika. Inganda nyinshi zikora filime nazo zihanganye n’udushya mu ikoranabuhanga, kandi zigenda zitera imbere buhoro buhoro zigana ku mafilime y’inganda ashobora kongera gukoreshwa afite ireme n’imikorere myiza. Ariko, bitewe n’uko filime za pulasitiki zishobora kwangirika, hari ibisabwa bikomeye byo gupfunyika hanze, cyangwa ubusabe bw’ibicuruzwa byo gupfunyika hanze bigomba kubikwa igihe kirekire nyuma y’igihe cyo kwangirika, kandi filime z’inganda n’izindi nzego ziracyadashobora gusimburwa, bityo filime ziracyakoreshwa. Yabayeho nk’igicuruzwa cy’ingenzi kiri munsi ya poliyetinamu igihe kirekire, ariko hashobora kubaho kugabanuka k’ubwiyongere bw’ibikoreshwa no kugabanuka k’umubare.

Byongeye kandi, inganda nka "injection molding", "imiyoboro", n'imyobo bifitanye isano rya hafi n'umusaruro n'ubuzima bizakomeza kuba ibicuruzwa by'ingenzi bikoreshwa inyuma ya polyethylene mu myaka mike iri imbere, kandi bizakomeza kwibanda ku bikorwa remezo, ibintu bikenerwa buri munsi, n'ibikoresho bya leta n'ibikoresho. Imibereho y'abaturage ifitanye isano n'ibicuruzwa biramba, kandi icyifuzo cyo kwangirika kw'ibicuruzwa kiragabanuka. Ikibazo nyamukuru inganda zavuzwe haruguru zihanganye nacyo muri iki gihe ni uko umuvuduko w'iterambere ry'urwego rw'ubutaka wahagaze mu myaka ya vuba aha. Bitewe n'ibintu nk'ibitekerezo bibi ku bijyanye n'ikoreshwa ry'ibicuruzwa by'abaturage byatewe n'icyorezo gikomeje kwiyongera, iterambere ry'inganda zikora ibicuruzwa riri guhangana n'izamuka ry'ibiciro. Kubwibyo, impinduka mu gihe gito ni nke, ntizibangamirwa cyane n'ibicuruzwa byangiritse, inganda zikora ibikoresho by'imiyoboro zishobora kugirwaho ingaruka na politiki, mu gihe "injection molding" n'ibicuruzwa by'imyobo bigirwaho ingaruka cyane n'ikoreshwa ry'abaturage, kandi umuvuduko w'izamuka uzagabanuka mu gihe runaka mu gihe kizaza.

Bitewe n’iterambere rikomeje rya siyansi n’ikoranabuhanga, impinduka ku giti cyazo no kuvugurura imiterere y’ibicuruzwa bya pulasitiki, ndetse n’ubuhanga mu bicuruzwa ndetse n’ibisabwa mu gukora ibintu byihariye nabyo bihora bitera imbere. Kubwibyo, mu gihe kizaza, inganda zikora ibikoresho bya pulasitiki zizongera icyifuzo cy’ibikoresho bimwe na bimwe fatizo bizamura imikorere y’ibicuruzwa bya pulasitiki, nka metallocenes, plastike zizunguruka, ibikoresho byo gusiga irangi n’ibindi bicuruzwa bifite agaciro gakomeye cyangwa ibicuruzwa bifite ibisabwa byihariye mu nzego zihariye. Byongeye kandi, kubera umusaruro mwinshi w’ibigo bitunganya polyethylene mu myaka ya vuba aha, byatumye ibicuruzwa bihinduka cyane, kandi amakimbirane hagati y’Uburusiya na Ukraine mu mwaka yatumye ibiciro bya peteroli bizamuka cyane bizamuka inyungu za ethylene, kandi ukwiyongera kw’ibiciro n’itangwa byatanze umusaruro uhuye cyane. Muri iki gihe, abakora polyethylene barimo gukora cyane mu gukora ibicuruzwa bifite agaciro gakomeye nka metallocenes, rotational molding, na coatings, hakurikijwe iterambere ry’inganda zikora. Kubwibyo, umuvuduko w’izamuka ry’ibicuruzwa ushobora kwiyongera ku rugero runaka mu gihe kizaza.

Byongeye kandi, uko icyorezo gikomeza kwiyongera, ndetse n'ubushakashatsi n'iterambere ry'ibirango bishya bikorwa n'inganda, insinga za polyethylene, ibikoresho byihariye by'ubuvuzi n'ibicuruzwa birinda nabyo birakurikiranwa buhoro buhoro kandi bigatezwa imbere, kandi ubusabe bw'ejo hazaza nabwo buziyongera buhoro buhoro.
