Polythene ni imwe muri pulasitiki ikunzwe cyane ku isi. Ni polymeri ishobora gukoreshwa mu buryo butandukanye, kuva kuri firime zirinda ubushuhe bwinshi kugira ngo zubakwe mushya kugeza ku mifuka n'firime byoroshye kandi byoroshye.

Ubwoko bubiri bw'ingenzi bwa PE bukoreshwa mu ishami rya filime no mu gupakira ibintu byoroshye – LDPE (ubucucike buke), bukunze gukoreshwa ku ma pallet na filime zikomeye nk'amasakoshi n'amasakoshi biramba, imiyoboro ya polyethylene, filime zo kurinda, amasakoshi y'ibiribwa, n'ibindi.HDPE (ubucucike buri hejuru)Ku bikoresho byinshi byo mu bwoko bwa "thin-gauge totes", imifuka y'ibiribwa bishya, hamwe n'amacupa n'imipfundikizo.

Hari ubundi bwoko bubiri bw'ingenzi. Ibicuruzwa byose bifite ubushobozi bwiza bwo kubuza umwuka cyangwa ubushuhe kandi ntibikoreshwa mu buryo bwa shimi.

Mu guhindura imiterere ya polyethylene n'ibipimo byayo, abakora/abatunganya ibintu bashobora guhindura ingaruka no kudacika kw'amarira; ubwumvikane n'uko ibintu bimeze; ubworoherane, ubushobozi bwo gushushanya, no gusiga/gusiga/gucapa. PE ishobora kongera gukoreshwa, kandi imifuka myinshi y'imyanda, filime z'ubuhinzi, n'ibicuruzwa biramba nka intebe zo muri pariki, bollards, n'udusanduku tw'imyanda bikoresha polyethylene yongeye gukoreshwa. Bitewe n'agaciro kayo ka karori nyinshi,Ibitangwa na PEkugarura ingufu neza binyuze mu gutwika neza.

Ibikoresho byo mu busitani bikozwe muri polyethylene ifite ubucucike bwinshi. Igiciro gito, gukomera cyane no koroshya gucura ibi bikoresho bituma iki gikoresho kiba amahitamo asanzwe yo gukoresha mu bikoresho byo mu busitani.

Icupa rya pulasitiki rya HDPE
Amacupa ya pulasitiki ya polyethylene ifite ubucucike bwinshi (HDPE) ni amahitamo akunzwe yo gupakira ku masoko y'amata n'imitobe mishya. Urugero, mu Bwongereza, amacupa agera kuri miliyari 4 yo kugaburira HDPE arakorwa kandi akagurwa buri mwaka.

HDPE itanga inyungu nyinshi ku bakinnyi, abacuruzi n'abaguzi.

Ibyiza by'amacupa ya HDPE
Ishobora kongera gukoreshwa: Amacupa ya HDPE ashobora kongera gukoreshwa 100%, bityo ibikoresho bishobora kongera gukoreshwa

Irambye: HDPE itanga amahirwe yo kongera gushyira ibikoresho byasubijwe mu ruhererekane rw'ibicuruzwa

Gupima Byoroshye: Amacupa ya HDPE atanga amahirwe akomeye yo gupima Byoroshye

Ishobora gukoreshwa mu buryo bugezweho: icupa rya pulasitiki ryonyine rishobora gukoreshwa nk'icupa ry'amata ryashyizwemo pasteurized, cyangwa nk'icupa rya UHT cyangwa icupa ryakuwemo sterilized milk barrier

Uburyo bworoshye bwo gukoresha: Ubwoko bwonyine bwo gupfunyika butuma imigozi n'imyobo byo gusukamo bihuzwa neza kugira ngo bifatirwe kandi bisurwe neza

Ifite umutekano kandi itekanye: Ubwoko bwonyine bw'ipaki bushobora kugira agapfundikizo k'inyuma gashobora kwangirika cyangwa agapfundikizo k'ubushyuhe kugira ngo hirindwe gusohoka, kubungabunga ubushya bw'ibicuruzwa, no kugaragaza ibimenyetso by'uko byangiritse

Ubucuruzi: Amacupa ya HDPE atanga amahirwe menshi yo kwamamaza, nko gucapa ku gikoresho, gucapa ku gitambaro cyangwa ku kirango, ndetse no guhindura imiterere kugira ngo igaragare neza ku gikoresho.

Udushya: Ubushobozi bwo kurenga imipaka no kugera ku ntambwe nshya binyuze mu gukoresha ibikoresho bishya byo gushushanya.

amakuru ajyanye n'ibidukikije
Amacupa y'abana ya HDPE ni amwe mu mapaki akoreshwa cyane mu Bwongereza, amakuru aturuka muri Recoup agaragaza ko hafi 79% by'amacupa y'abana ya HDPE akoreshwa mu bundi buryo.
Ugereranyije,Amacupa ya HDPEmu Bwongereza ubu bari ku kigero cya 15% ugereranyije n'uko bari bari mu myaka itatu ishize.

Ariko, imiterere mishya nk'icupa rya Infini ryatsindiye ibihembo bivuze ko ubu bishoboka kugabanya uburemere bw'amacupa asanzwe kugeza kuri 25% (bitewe n'ingano)

Ugereranyije, amacupa ya HDPE mu Bwongereza akubiyemo 15% by'ibikoresho byasubijwemo

Ariko, iterambere mu ikoranabuhanga n'ibishushanyo mbonera bishya by'ibicuruzwa bivuze ko ibintu bishya byagezweho. Urugero, mu 2013, Nampak yongereye 30% bya HDPE yasubiwemo mu macupa yayo y'amata ya Infini, ikaba ari yo ya mbere ku isi—imyaka ibiri mbere y'intego y'inganda.
