Kugirango wongere ubuzima bwibiryo, imiti nibindi bikoresho, ibyinshi mubiribwa n'ibikoresho bipakira ibiyobyabwenge ubu bifashisha firime nyinshi.Kugeza ubu, hari ibice bibiri, bitatu, bitanu, birindwi, icyenda, ndetse na cumi na kimwe cyibikoresho byo gupakira.Filime ya Multi-layer co-extrusion ni firime ikuramo ibikoresho bitandukanye bya pulasitike biva kumupfa umwe icyarimwe binyuze mumiyoboro myinshi, ishobora guha gukina ibyiza byibikoresho bitandukanye.
Multi-layer co-extruded compteur igizwe ahanini na polyolefin.Kugeza ubu, inyubako zikoreshwa cyane zirimo: polyethylene / polyethylene, polyethylene / vinyl acetate copolymer / polypropylene, LDPE / igipande / EVOH / igikoresho gifata / LDPE, LDPE / igipande / EVOH / EVOH / igipande / LDPE.Ubunini bwa buri cyiciro burashobora guhindurwa nuburyo bwo gukuramo.Muguhindura ubunini bwurwego rwa bariyeri no gukoresha ibikoresho bitandukanye bya barrière, firime ifite imiterere ya barrière itandukanye irashobora gutegurwa kuburyo bworoshye, kandi ibikoresho bifunga ubushyuhe nabyo birashobora guhinduka kandi bigatangwa kugirango bikemurwe.Iyi mikorere myinshi kandi ikora byinshi-ifatanyabikorwa hamwe nicyerekezo nyamukuru cyiterambere ryiterambere ryibikoresho bya firime mugihe kizaza.
