Ese pulasitiki ya PE ifite umutekano ku biribwa?

Plasitiki ya polyethylene (PE), ni igikoresho gikoreshwa cyane mu gupakira ibiryo, cyakunzwe cyane kubera ubushobozi bwayo bwo gukora ibintu bitandukanye n'umutekano wayo. Plasitiki ya PE ni polymeri igizwe n'ibice bya ethylene, izwiho kuba ihamye kandi idakora ibintu byinshi. Iyi miterere ituma PE iba amahitamo meza yo gukoresha mu rwego rw'ibiribwa, kuko idashyira imiti yangiza mu biribwa, kabone n'iyo yaba iri mu bushyuhe butandukanye.

Inyigisho n'amabwiriza agenga umutekano

Ubushakashatsi bwimbitse n'amabwiriza akaze bireba ko pulasitiki yo mu bwoko bwa PE ifite ingano y'ibiribwa itekanye ku biryo. Ubushakashatsi bwagaragaje ko pulasitiki yo mu bwoko bwa PE idasohora ibintu byangiza mu gihe ikoreshwa mu buryo busanzwe. Inzego zishinzwe kugenzura nka Ikigo gishinzwe ibiribwa n'imiti muri Amerika (FDA) n'Ikigo cy'Uburayi gishinzwe umutekano w'ibiribwa (EFSA) zashyizeho amabwiriza n'amahame pulasitiki yo mu bwoko bwa PE igomba kuba yujuje kugira ngo ishyirwe mu cyiciro cy'ibiribwa. Aya mahame arimo gupima ko hari imiti yimuka, kwemeza ko iyo ari yo yose iva muri pulasitiki ijya mu biryo iguma mu mupaka utekanye.

Uburyo Busanzwe bwo Gukoresha mu Gupakira Ibiryo

Plasitiki ya PE ikoreshwa cyane mu buryo butandukanye bwo gupfunyika ibiryo, harimoAmasakoshi ya PE, amasakoshi ya zipu, naimifuka ifunguye. Iyi miti yo gupfunyika itanga ubushobozi bwo kwirinda ubushuhe, koroherana no kuramba, bigatuma ikoreshwa neza mu kubika ibiryo bitandukanye. Urugero, imifuka ya PE ikunze gukoreshwa mu biryo bishya, mu byo kurya biryoshye, no mu biryo bikonjeshejwe bitewe n'ubushobozi bwayo bwo kubika ubushyuhe no kongera igihe cyo kubibika.

Kugereranya n'izindi plastiki

Ugereranyije n'izindi plastiki, nka polyvinyl chloride (PVC) na polystyrene (PS), plastiki ya PE ifatwa nk'ifite umutekano kandi irinda ibidukikije. Urugero, PVC ishobora kurekura imiti yangiza nka phthalate na dioxins, cyane cyane iyo ishyushye. Mu buryo bunyuranye, imiterere yoroheje ya PE plastic hamwe n'uburyo ihagaze bituma iba amahitamo meza yo gupakira ibiryo, kuko itera ibyago bike byo kwandura.

Gushyigikira Amakuru n'Ubushakashatsi

Amakuru yavuye mu bushakashatsi bw’inganda ashyigikira umutekano wa pulasitiki ya PE. Urugero, ubushakashatsi bwakozwe na EFSA bwagaragaje ko kwimuka kw’ibintu biva muri pulasitiki ya PE bijya mu biribwa biri mu rugero rw’umutekano rwashyizweho. Byongeye kandi, kuba pulasitiki ya PE ishobora kongera gukoreshwa cyane birushaho kongera ubwiza bwayo, kuko ishobora gutunganywa neza ikaba ibicuruzwa bishya, bigagabanya ingaruka mbi ku bidukikije.

Mu gusoza,Amasakoshi ya PE, amasakoshi ya zipu, naimifuka ifunguyeIbikoresho bya pulasitiki yo mu rwego rwa PE ni amahitamo meza kandi yizewe yo gupakira ibiryo. Ingufu zabyo zihamye, kubahiriza amahame y’umutekano, no gukoreshwa cyane mu nganda bituma biba amahitamo meza ku baguzi bashaka kubika no kurinda ibiryo byabo. Kugira ngo umenye byinshi kuri pulasitiki yo mu rwego rwa PE n'ikoreshwa ryayo, nyamuneka reba inyandiko zatanzwe.
