Urebye umubare wamahitamo aboneka, guhitamo igikapu gikwiye cya plastiki birashobora kuba umurimo utoroshye.Ibyo ahanini biterwa nuko imifuka ya pulasitike ikozwe mubikoresho bitandukanye kandi buri kimwe muri ibyo bikoresho gitanga abakoresha ibintu byihariye.Ziza kandi muburyo butandukanye buvanze n'amabara.
Hano hari verisiyo nyinshi yimifuka ya pulasitike hanze, ariko, nukumenyera buri bwoko, urashobora rwose kugabanya amahitamo yawe menshi hanyuma ugahitamo igikapu gikwiye kubyo ukeneye.Noneho, reka twibire kandi turebe ubwoko butandukanye bwimifuka ya plastike iboneka kumasoko uyumunsi:
Umuvuduko mwinshi Polyethylene (HDPE)
Imwe muri plastiki ikunze gukoreshwa kwisi yose, HDPE igaragaramo imico itandukanye, bigatuma iba ibikoresho byiza byo gukora imifuka ya pulasitike.Nibyoroshye, bisa neza, amazi nubushyuhe birwanya, kandi bifite imbaraga nyinshi.
Usibye ibyo, imifuka ya pulasitike ya HDPE yujuje amabwiriza yo gutunganya ibiryo bya USDA na FDA, bityo bikaba amahitamo akunzwe haba kubika no gutanga ibiryo mu gufata no gucuruza.
Imifuka ya pulasitike ya HDPE irashobora kuboneka muri resitora, mububiko bworoshye, mububiko bwibiryo, delis ndetse no mumazu yo kubika no gupakira.HDPE ikoreshwa kandi mumifuka yimyanda, imifuka yingirakamaro, imifuka ya T-shirt, n imifuka yo kumesa, nibindi.
Ubucucike buke Polyethylene (LDPE)
Ubu bwoko bwa plastike bukoreshwa mubikapu byingirakamaro, imifuka yibiribwa, imifuka yimigati kimwe namashashi afite imbaraga ziciriritse kandi zirambuye.Nubwo LDPE idakomeye nkimifuka ya HDPE, irashobora kubika ibintu byinshi, cyane cyane ibiryo ninyama.
Byongeye kandi, plastiki isobanutse ituma byoroha kumenya ibirimo, kwemerera resitora gukomeza kugumya kwihuta mubikoni byubucuruzi.
Ibyo byavuzwe, imifuka ya pulasitike ya LDPE irahuze cyane kandi irazwi cyane gukoreshwa hamwe no gufunga ubushyuhe kubera aho bishonga.LDPE yujuje kandi amabwiriza yo gutunganya ibiryo USDA na FDA kandi nayo rimwe na rimwe ikoreshwa mugukora ibipfunyika.
Umurongo muto Ubucucike Polyethylene (LLDPE)
Itandukaniro nyamukuru hagati yimifuka ya plastike ya LDPE na LLDPE nuko iyanyuma ifite igipimo cyoroheje.Nyamara, ikintu cyiza kuri iyi plastiki nta tandukaniro ryimbaraga, ryemerera abakoresha kuzigama amafaranga nta gutambamira ubuziranenge.
Imifuka ya LLDPE yerekana urwego ruciriritse kandi ikoreshwa mugukora imifuka y'ibiryo, imifuka y'ibinyamakuru, imifuka yo guhaha kimwe n imifuka yimyanda.Barashobora kandi gukoreshwa mububiko bwibiryo muri firigo na firigo, bitewe nuko bikoreshwa mububiko bwibiribwa byinshi mubikoni byubucuruzi.
Ubucucike buciriritse Polyethylene (MDPE)
MDPE iragereranijwe neza kuruta HDPE, ariko ntabwo isobanutse nka polyethylene nkeya.Amashashi akozwe muri MDPE ntaho ahuriye nimbaraga zo hejuru, kandi ntanubwo arambuye neza, ntabwo rero akundwa gutwara cyangwa kubika ibicuruzwa byinshi.
Nyamara, MDPE nigikoresho gisanzwe kumifuka yimyanda kandi ikoreshwa mubipfunyika byabaguzi kubicuruzwa byimpapuro nkimpapuro zikora cyangwa igitambaro cyimpapuro.
Polypropilene (PP)
Imifuka ya PP irangwa nimbaraga zidasanzwe za chimique no kurwanya.Bitandukanye nandi mifuka, imifuka ya polypropilene ntabwo ihumeka kandi nibyiza mubihe byo kugurisha bitewe nigihe kirekire cyo kubaho.PP ikoreshwa kandi mubipfunyika ibiryo, aho ibintu nka bombo, ibinyomoro, ibyatsi nibindi bicuruzwa bishobora kubikwa byoroshye mumifuka ikozwemo.
Iyi mifuka irasobanutse neza kurenza iyindi, ituma abayikoresha bongera kugaragara.Imifuka ya PP nayo ni nziza mu gufunga ubushyuhe bitewe n’ahantu ho gushonga, kandi, kimwe n’ubundi buryo bwo guhitamo imifuka ya pulasitike, ni USDA na FDA byemewe gutunganya ibiryo.
