Ibikoresho bishya byo gupakira: Filime yo gupakira ibintu byinshi (Igice cya 2)

Ibiranga ibice byinshi byo gupakira firime

Imikorere ikomeye
Gukoresha polimeri nyinshi aho kuba polymerisiyasi imwe irashobora kunoza cyane imikorere yinzitizi ya firime yoroheje, ikagera ku ngaruka zikomeye kuri ogisijeni, amazi, dioxyde de carbone, impumuro, nibindi bintu. Cyane cyane iyo ukoresheje EVOH na PVDC nkibikoresho bya barrière, umwuka wa ogisijeni hamwe nu mwuka wamazi ni muke cyane.
Imikorere ikomeye
Bitewe no guhitamo kwinshi kwa byinshifirime yo gupakira ibiryomubikoresho bifatika, ibisigazwa byinshi birashobora gutoranywa ukurikije ikoreshwa ryibikoresho byakoreshejwe, bikagaragaza neza imikorere yinzego zitandukanye, kuzamura imikorere ya firime zasohotse, nko kurwanya amavuta, kurwanya ubushuhe, kurwanya ubushyuhe bwo guteka, hamwe no hasi -ubushyuhe bwo gukonjesha. Irashobora gukoreshwa mugupakira vacuum, gupakira sterile, no gupakira.

Igiciro gito
Ugereranije no gupakira ibirahuri, gupakira aluminiyumu, nibindi bikoresho bya pulasitike,umuzingo wa firimeifite inyungu zingirakamaro mugushikira ingaruka zimwe. Kurugero, kugirango ugere kuri bariyeri imwe, firime irindwi co extruded firime ifite inyungu nziza kuruta ibice bitanugupakira firime. Bitewe nubuhanga bworoshye, ibiciro byibicuruzwa bya firime byakozwe birashobora kugabanukaho 10-20% ugereranije na firime yumye hamwe nizindi firime.
Igishushanyo mbonera
Kwemeza ibishushanyo mbonera bitandukanye kugirango byuzuze ibisabwa mubicuruzwa bitandukanye.
