Cellophane bụ ngwaahịa nkwakọ ngwaahịa doro anya kacha ochie nke ejiri kechie kuki, candies na mkpụrụ.A na-ere ahịa Cellophane na United States na 1924 ma bụrụ ihe nkiri nkwakọ ngwaahịa bụ isi ejiri ruo 1960.N'ahịa nke na-ahụ maka gburugburu ebe obibi taa, cellophane na-alọghachi.N'ihi na cellophane bụ 100% biodegradable, a na-ahụ ya dị ka ihe ọzọ na-emetụta gburugburu ebe obibi na nkwakọ ngwaahịa dị ugbu a.Cellophane nwekwara nkezi uzuoku uzuoku dị ka nke ọma dị ka igwe eji arụ ọrụ na njikwa ọkụ, na-agbakwunye na ewu ewu ugbu a na ahịa nkwakọ ngwaahịa nri.
N'adịghị ka polymers mmadụ mere na rọba, bụ nke a na-esi na mmanụ ala nweta, cellophane bụ polymer eke sitere na cellulose, nke bụ akụkụ nke osisi na osisi.A naghị emepụta Cellophane site na osisi ọhịa mmiri ozuzo, kama site na osisi ndị a na-eto ma na-egbute kpọmkwem maka mmepụta cellophane.
A na-eme Cellophane site n'ịgbari osisi na pulp owu n'ụdị bat nke kemịkalụ na-ewepụ adịghị ọcha ma na-akụda ụdọ eriri ogologo dị na akụrụngwa a.Emegharịrị ka ọ bụrụ ihe nkiri doro anya, kenkowaputa nke nwere kemịkalụ plastik agbakwunyere iji meziwanye mgbanwe, cellophane ka na-abụkarị nke mkpụrụ ndụ cellulose crystalline mejupụtara.
Nke a pụtara na enwere ike imebi ya site na microorganisms dị na ala dịka akwụkwọ na osisi.Cellulose so na klas nke ogige dị na kemịkalụ organic a na-akpọ carbohydrates.Akụkụ bụ isi nke cellulose bụ molekul glucose.Ọtụtụ puku ụmụ irighiri glucose ndị a na-agbakọta ọnụ n'oge usoro ntoju nke osisi ahụ iji mepụta agbụ ogologo a na-akpọ cellulose.Agbụ ndị a, n'aka nke ya, na-akụda n'oge mmepụta na-emepụta ihe nkiri cellulose nke a na-eji n'ụdị a na-ekpuchighị ma ọ bụ mkpuchi na nkwakọ ngwaahịa.
Mgbe e liri ya, ihe nkiri cellulose na-enweghị mkpuchi na-emebikarị n'ime ụbọchị 10 ruo 30;Achọpụtara ihe nkiri ndị nwere mkpuchi PVDC na-eweda n'ime ụbọchị 90 ruo 120, na cellulose nke nwere nitrocellulose mebiri n'ime ụbọchị 60 ruo 90.
Nnwale egosiwo na nkezi ngụkọta oge iji mechaa biodegradation nke ihe nkiri cellulose bụ ụbọchị 28 ruo 60 maka ngwaahịa na-enweghị mkpuchi na ụbọchị 80 ruo 120 maka ngwaahịa cellulose mkpuchi.N'ime mmiri ọdọ mmiri, ọnụọgụ biodegradation bụ ụbọchị 10 maka ihe nkiri a na-enweghị mkpuchi na ụbọchị 30 maka ihe nkiri cellulose mkpuchi.Ọbụna ihe ndị a na-ewere dị ka ihe na-emebi emebi, dị ka akwụkwọ na akwụkwọ ndụ akwụkwọ ndụ, na-ewe ogologo oge iji mebie karịa ngwaahịa ihe nkiri cellulose.N'ụzọ dị iche, plastik, polyvinyl chloride, polyethylene, polyethylene terephthalate na polypropylene gbadoro anya gosiri ntakịrị ihe na-emebi emebi mgbe e liri ya ogologo oge.
