Filime zigizwe n'ibice byinshi by'urukuta rurerure

Filime za Composite zo mu bwoko bwa High Barrier ni iki?

Filimi zikozwe mu buryo bw’urutare rurerure ni filime zifite laminate nyinshi zagenewe kurinda ibirimo gupfunyika umwuka wa ogisijeni, ubushuhe, impumuro nziza, urumuri, n'ibindi bintu byo hanze.
Izi filime zikunze guhuza ibikoresho nka PET , Nylon, EVOH, aluminiyumu, na PE/CPP kugira ngo zigere ku musaruro mwiza w’urutare.
Zikoreshwa cyane mu biryo, imiti, n'inganda zipfunyikamo ibisaba igihe kirekire kandi zigatanga umusaruro uhagije.

Ni ibihe bikoresho bikunze gukoreshwa muri firime zifite uburebure bw'ingufu?

Imiterere isanzwe y'ibikoresho irimo:
• PET /AL/PE (Filimu y'urupapuro rwa aluminiyumu)
​​• PET /NY/PE
• BOPP/EVOH/CPP
• Nayiloni/PE ifite urwego rw'ibanze rwa EVOH
• Filimu y'urupapuro rwa metallized PET cyangwa BOPP.
Iyi mikoranire y'urupapuro rwinshi ituma umwuka wa ogisijeni n'ubushuhe birushaho gukomera mu gihe ikomeza koroha no gufunga neza.

Ni izihe nyungu z'ingenzi zo gukoresha filime zivanze zifite imigozi myinshi?

Filimi zifite uburebure bunini zitanga ibyiza bikurikira:
• Imiterere myiza y’ingufu zo kubuza umwuka n’ubushuhe
• Igihe kirekire cyo kubika ibicuruzwa no kubibika neza
• Impumuro nziza, uburyohe, no kurinda imirasire ya UV
• Bikwiriye gupakira mu cyuma gifunga ibintu mu buryo bw’umwuka no gupakira mu kirere gihinduwe ( MAP )
• Ahantu hacapirwa ho gushyira ikirango no kwandikaho
• Ingufu zikomeye za mekanike no kurwanya gutobora.

Ni izihe porogaramu zisaba filime zifite uburebure bunini?

Filimi zivanze cyane zikoreshwa cyane mu:
• Inyama, sosiso, n'ibikomoka ku mafi bipfunyitse mu cyuma
• Ikawa, icyayi, n'ibiryo byo mu bwoko bwa “snack packing”
• Imiti n'ibikoresho by'ubuvuzi
• Ipaki y'ibiribwa birimo foromaje, amata, n'ifu
• Ibiryo by'amatungo n'inyongeramusaruro
• Ibikoresho by'ikoranabuhanga n'ibikomoka ku bushyuhe mu nganda

Ni gute filime zigaragaza imiterere y'ikirere zigereranywa na filime zisanzwe?

Filimi zisanzwe zivanze zishobora gutanga uburinzi bw'ibanze ariko ntizikwiriye ibicuruzwa bisaba kubikwa igihe kirekire.
Filimi zifite uburebure buri hejuru zirimo urwego rwihariye nka aluminiyumu foil, EVOH, cyangwa PET yakozwe mu byuma kugira ngo bigabanye cyane igipimo cyo kwanduza umwuka n'ubushuhe (OTR na MVTR).
Zituma ibicuruzwa birindwa neza, cyane cyane mu gihe bibikwa cyangwa mu gihe cyo gutwara ibintu.

Ese firime zifite uburebure bw'umugozi zikwiriye gupakira ibintu bivamo umwuka na MAP ?

Yego, firime zivanze n'imigozi miremire zikunze gukoreshwa mu mifuka ifunze neza no mu ipaki y'ikirere yahinduwe ( MAP ).
Ifite ubushobozi buke bwo kwinjira mu mubiri bifasha gukuraho ogisijeni no kugumana azote cyangwa CO₂, bikongera ubushyuhe no kubuza mikorobe gukura.
Zikoreshwa cyane mu gutunganya inyama, gupakira foromaje, no mu ifunguro ryiteguye kuribwa.

Ese filime zishobora gufungwa, gucapwa, cyangwa guhindurwa?

Yego rwose. Izi firime zishobora gupfundikirwa n'ubushyuhe cyangwa gupfundikirwa n'ubukonje, bitewe n'urwego rwo gupfundikirwa (PE, CPP, EVA, nibindi).
Zirahuye na gravure, flexo, na digital printing.
Ibintu byifashishwa harimo gucikamo uduce tworoshye, zipper zishobora kongera gupfundikirwa, anti-hug coating, na laser scoring.
Ubunini, urwego rw'imbogamizi, hamwe n'uburyo bwo gutunganya ubuso byose bishobora guhindurwa hakurikijwe ibikenewe mu gupfundikirwa.

Ese izi filime zifite umutekano mu biribwa kandi zikurikiza amabwiriza?

Yego, filime zivanze n’ibiryo zo mu rwego rwo hejuru zikorwa hakurikijwe amabwiriza ya FDA, EU, na GB.
Ni nziza ku buryo zishobora guhuzwa n’ibiribwa n’ibinyobwa, harimo n’ibikonjeshwa, bikonjeshwa, n’ibishobora gusubizwa inyuma.
Impamyabumenyi z’isesengura (COA), raporo z’ibizamini byo kwimuka, n’amakuru y’ibikoresho urupapuro bishobora gutangwa iyo ubisabye.

Ni ubuhe bunini buboneka ku mafirime afite uburebure bunini?

Ubunini busanzwe buri hagati ya mikoroni 50 na mikoroni 180 bitewe n'imiterere n'ikoreshwa.
Filimi zo mu isanduku y'imyanda muri rusange ziba mikoroni 70-150, mu gihe imigozi y'ibiryo byoroshye ishobora kuba nto (mikoroni 20-60).
Imiterere yihariye ishobora gukorwa hashingiwe ku buryo ibicuruzwa birushaho kuba byiza no ku buryo ikoranabuhanga rikoreshwa.

Ese firime zifite uburebure bunini zishobora kongera gukoreshwa cyangwa ntizingiza ibidukikije?

Filimi gakondo zikoreshwa mu bikoresho byinshi biragoye kongera gukoreshwa.
Ariko, filime zikoreshwa mu bikoresho bimwe zishobora kongera gukoreshwa (urugero, zose-PE cyangwa zose-PP) ziragenda ziboneka cyane, zitanga ibisubizo birambye byo gupfunyika.
Bamwe mu bakora kandi batanga filime zikoreshwa mu bikoresho bikoreshwa mu gufumbira nka PLA cyangwa selulose.
Ni ngombwa guhuza ibikenewe mu mikorere n'intego zo gukomeza mu gihe cyo guhitamo filime.
