Nibikoresho byumwuga byo gufunga byateguwe neza nisosiyete ishingiye kumyaka yubushakashatsi bwimbitse no gusobanukirwa neza ibiranga umubiri na chimique bidasanzwe biranga PE. Imikorere yimikorere yibikoresho biroroshye cyane, kandi abashya barashobora gutangira vuba; Ingaruka yo gushiraho ikimenyetso irakomeye kandi yizewe, irashobora kwemeza neza imikorere yikimenyetso; Umusaruro urenze kure cyane ibicuruzwa bisa, bishobora kuzamura cyane umusaruro; Byongeye kandi, ibikoresho bifite ubuzima bwiza kandi burambye bwa serivisi, bishobora kuzigama ibikoresho byinshi byo gusimbuza no gufata neza imishinga. Iyi mashini ifunga kashe ikwiriye cyane cyane gufunga imifuka iremereye ya PE ipakira imifuka hamwe nudukapu twinshi, kandi itanga igisubizo cyiza kandi cyiza kubikorwa bijyanye nibikorwa.
