Yonke into omawuyazi malunga nePackaging yeCellulose
Ukuba ujonge kwizinto zokupakisha ezihambelana nokusingqongileyo, amathuba okuba ukhe weva ngeselulosi, ekwabizwa ngokuba yi-cellophane.
I-Cellophane yinto ecacileyo, e-crinkly ekhoyo ukususela ekuqaleni kwe-1900s.Kodwa, kunokukumangalisa ukufunda ukuba i-cellophane, okanye i-cellulose film packaging, isekelwe kwisityalo, i-compostable, kunye nemveliso "eluhlaza" ngokwenene.
Yintoni ukupakishwa kweselulosi?
Yafunyanwa ngo-1833, i-cellulose yinto engaphakathi kweendonga zeeseli zezityalo.Yenziwe ngetsheyini elide leemolekyuli zeglucose, iyenza i-polysaccharide (igama lenzululwazi lecarbohydrates).
Xa amatyathanga e-cellulose e-hydrogen edibana kunye, enza into ebizwa ngokuba yi-microfibrils, engenakuguquguquka ngokumangalisayo kwaye yomelele.Ukuqina kwezi microfibrils kwenza i-cellulose ibe yimolekyuli egqwesileyo ukuba isetyenziswe kwimveliso ye-bioplastic.
Ngaphezu koko, i-cellulose yeyona biopolymer ininzi kwihlabathi liphela, kwaye amasuntswana ayo anempembelelo encinci yokusingqongileyo.Nangona kukho iindlela ezininzi ezahlukeneyo zeselulosi.Ukupakishwa kokutya kweCellulose kudla ngokuba yi-cellophane, into ecacileyo, ebhityileyo, enokubola okufana neplastiki.
Zenziwa njani iimveliso zokupakishwa kwefilimu yeselulosi?
I-Cellophane yenziwa kwi-cellulose ethathwe kumqhaphu, umthi, i-hemp, okanye ezinye iindawo zendalo ezivunwa ngokuzinzileyo.Iqala njengentlaka emhlophe enyibilikayo, eyi-92% -98% yeselulosi.Emva koko, i-pulp ye-cellulose ekrwada idlula kula manyathelo mane alandelayo ukuze iguqulwe ibe yi-cellophane.
1. I-cellulose iyachithwa kwi-alkali (isiseko, ityuwa ye-ionic yekhemikhali yensimbi ye-alkaline) kwaye emva koko igugile iintsuku eziliqela.Le nkqubo yokunyibilika ibizwa ngokuba yi-mercerization.
2. I-Carbon disulfide isetyenziswe kwi-pulp ye-mercerized ukudala isisombululo esibizwa ngokuba yi-cellulose xanthate, okanye i-viscose.
3. Esi sisombululo songezwa kumxube we-sodium sulfate kunye ne-dilute sulfuric acid.Oku kuguqula isisombululo sibe yi-cellulose.
4. Emva koko, ifilimu ye-cellulose ihamba ngeendlela ezintathu zokuhlambela.Okokuqala ukususa isulfure, emva koko udibanise ifilimu, kwaye ekugqibeleni ungeze i-glycerin yokuqina.
Isiphumo sokugqibela yi-cellophane, esetyenziswa kwishishini lokupakisha ukutya, ngokuyintloko ukwenza iibhegi ze-cellophane ze-biodegradable okanye "iingxowa ze-cello".
Ziziphi iingenelo zeemveliso ze-cellulose?
Nangona inkqubo yokudala ukupakishwa kwe-cellulose inzima, izibonelelo zicacile.
Abantu baseMelika basebenzisa i-100 yeebhiliyoni zeengxowa zeplastiki ngonyaka, ezifuna i-12 yeebhiliyoni zemiphanda yeoli rhoqo ngonyaka.Ngaphaya koko, izilwanyana zaselwandle ezili-100,000 zibulawa ngeengxowa zeplastiki nyaka ngamnye.Kuthatha ngaphezulu kweminyaka engama-20 ukuba iingxowa zeplastiki ezisekwe kwipetroleum zithobeke elwandle.Xa besenza njalo, benza ii-micro-plastiki eziqhubeka zingena kwikhonkco lokutya.
Njengoko uluntu lwethu lukhula ngakumbi ukukhathalela indalo esingqongileyo, siyaqhubeka sikhangela izinto ezilungele ukuphilisana kwendalo, ezona zinokonakala kwiiplastiki ezisekwe kwipetroleum.
Ngaphandle kokuba yenye yeplastiki, ukupakishwa kwefilimu ye-cellulose kunika izibonelelo ezininzi zokusingqongileyo:
Uzinzo kunye ne-bio-based
Ngenxa yokuba i-cellophane idalwe kwi-cellulose evunwe kwizityalo, yimveliso ezinzileyo efunyenwe kwi-bio-based, izibonelelo ezivuselelekayo.
I-Biodegradable
Ukupakishwa kwefilimu ye-Cellulose i-biodegradable.Iimvavanyo zibonise ukuba i-cellulose yokupakisha i-biodegrades kwiintsuku ezingama-28-60 ukuba imveliso ayifakwanga kunye neentsuku ezingama-80-120 ukuba zigqunywe.Ikwathoba emanzini kwiintsuku ezili-10 ukuba ayigqunywanga kwaye malunga nenyanga ukuba igqunywe.
Ivundisiwe
I-Cellophane ikwakhuselekile ukuba uyibeke kwingqumba yakho yomgquba ekhaya, kwaye ayifuni ndawo yorhwebo yokwenza umgquba.
Iinzuzo zokupakishwa kokutya:
Ixabiso eliphantsi
Ukupakishwa kweCellulose kukho ukusukela ngo-1912, kwaye yimveliso yemveliso yephepha.Xa kuthelekiswa nezinye iindlela zeplastiki eco-friendly, i-cellophane inexabiso eliphantsi.
Ukumelana nokufuma
Iingxowa ze-biodegradable cellophane zixhathisa ukufuma kunye nomphunga wamanzi, zizenza zibe lolona khetho lubalaseleyo lokubonisa nokugcina izinto zokutya.
I-oyile-resistant
Ngokwemvelo baxhathisa ioyile kunye namafutha, ngoko ke iingxowa ze-cellophane zilungile kwizinto ezibhakiweyo, amantongomane kunye nokunye ukutya okunamafutha.
Ubushushu buvalekile
I-Cellophane ivaleka ubushushu.Ngezixhobo ezifanelekileyo, unokukhawuleza kwaye ushushu ngokukhawuleza kwaye ukhusele iimveliso zokutya ezigcinwe kwiingxowa ze-cellophane.
Lithini ikamva lokupakishwa kweselulosi?
Ikamva leifilimu ye-celluloseukupakishwa kubonakala kuqaqambile.Ingxelo yeFuture Market Insights iqikelela ukuba ukupakishwa kweselulosi kuya kuba nesantya sokukhula sonyaka esiyi-4.9% phakathi kuka-2018 no-2028.
Amashumi asixhenxe ekhulwini kolo lwando kulindeleke ukuba lwenzeke kwicandelo lokutya neziselo.Ifilimu yokupakishwa kwe-biodegradable cellophane kunye neengxowa eziyeyona nto ilindelekileyo yokukhula.
I-Cellophane kunye nokupakishwa kokutya ayikuphela kwemveliso ye-cellulose esetyenziswayo.I-Cellulose yamkelwe yi-FDA ukuba isetyenziswe:
Izongezo zokutya
Iinyembezi zokwenziwa
Isithambiso seziyobisi
Unyango lwamanxeba
I-Cellophane ibonakala rhoqo kwishishini lokutya kunye nesiselo, amayeza, ukhathalelo lomntu, ukhathalelo lwasekhaya, kunye namacandelo okuthengisa.
Ngaba iimveliso zokupakisha zeselulosi zilungile kwishishini lam?
Ukuba ngoku usebenzisa iingxowa zeplastiki kwiilekese, amandongomane, izinto ezibhakiweyo, njl.njl., iingxowa zokupakisha ze-cellophane ziyindlela efanelekileyo.Yenziwe ngeresin ebizwa ngokuba yi-NatureFlex™ eyenziwe kwi-cellulose evela kwi-pulp yeplanga, iingxowa zethu zomelele, zicacile kwaye ziqinisekisiwe ukuba ziyavundiswa.
