Cellophane nigicuruzwa cya kera gisobanutse gikoreshwa mugupfunyika kuki, bombo nimbuto.Cellophane yagurishijwe bwa mbere muri Amerika mu 1924 kandi ni yo filime y'ibanze yo gupakira yakoreshejwe kugeza mu myaka ya za 1960.Muri iki gihe isoko ryita ku bidukikije, selofane iragaruka.Kuberako selileophane ibora 100%, ibonwa nkibidukikije byangiza ibidukikije muburyo bwo gupakira.Cellophane ifite kandi impuzandengo y'amazi yo mu mazi kimwe no gukoresha imashini nziza hamwe n'ubushyuhe bwo gufunga ubushyuhe, bikiyongeraho kugeza ubu ku isoko ryo gupakira ibiryo.
Bitandukanye na polymers yakozwe n'abantu muri plastiki, zikomoka ahanini kuri peteroli, selofane ni polymer karemano ikozwe muri selile, igizwe nibimera n'ibiti.Cellophane ntabwo ikozwe mubiti byamashyamba yimvura, ahubwo ikorwa mubiti byakuze kandi bigasarurwa byumwihariko kubyara selile.
Cellophane ikorwa no gusya ibiti hamwe nipamba mu ruhererekane rwogeramo imiti ikuraho umwanda kandi igasenya iminyururu miremire muri ibi bikoresho.Yongeye guhindurwa muri firime isobanutse, irabagirana hamwe n’imiti ya pulasitiki yongeweho kugirango irusheho guhinduka, selofane iracyari igizwe ahanini na molekile ya selile.
Ibi bivuze ko ishobora gusenywa na mikorobe mu butaka nk'amababi n'ibimera.Cellulose ni mubyiciro byimvange muri chimie organic bita karubone.Igice cyibanze cya selile ni molekile ya glucose.Ibihumbi n'ibihumbi bya molekile ya glucose bifatanyiriza hamwe mugihe cyikura ryikimera kugirango bibe iminyururu ndende yitwa selile.Iyi minyururu, nayo, isenyuka mugihe cyo gukora kugirango ikore firime ya selile ikoreshwa muburyo budafunze cyangwa busize mubipfunyika.
Iyo ushyinguwe, firime ya selile idapfunditswe mubisanzwe itesha agaciro muminsi 10 kugeza 30;Filime ikozweho na PVDC wasangaga yangirika mu minsi 90 kugeza 120, na selile ya nitrocellulose yanduye mu minsi 60 kugeza 90.
Ibizamini byagaragaje ko impuzandengo yigihe cyo kurangiza biodegradasiyo ya firime ya selile ari iminsi 28 kugeza kuri 60 kubicuruzwa bidatunganijwe niminsi 80 kugeza 120 kubicuruzwa bya selile.Mu mazi yikiyaga, igipimo cyibinyabuzima cyari iminsi 10 kuri firime idafunze niminsi 30 kuri firime ya selile.Ndetse ibikoresho bifatwa nkibintu byangirika cyane, nkimpapuro namababi yicyatsi, bifata igihe kinini kugirango bitesha agaciro ibicuruzwa bya firime ya selile.Ibinyuranye na byo, plastiki, polyvinyl chloride, polyethylene, polyethylene terephthalate hamwe na polypropilene yerekanwe byerekanaga ibimenyetso bike byo kwangirika nyuma yo gushyingurwa igihe kirekire.
Filime ya selofane ikoreshwa muburyo butandukanye bwo gupakira, harimo:
- Candy, cyane cyane gupfunyika
- Gukarisha amakarito
- Umusemburo
- foromaje yoroshye
- Gupakira Tampon
.
- urwego rwibiryo
- Igikoresho cya Nitrocellulose
- PVDC
- Gupakira imiti
- kaseti
- Filime y'amabara
