Chilichonse Chimene Muyenera Kudziwa Zokhudza Ma cellulose Packaging
Ngati mwakhala mukuyang'ana zoyikapo zosunga zachilengedwe, mwayi ndiwe kuti mudamvapo za cellulose, yomwe imadziwikanso kuti cellophane.
Cellophane ndi zinthu zomveka bwino, zokhotakhota zomwe zakhala zikuchitika kuyambira koyambirira kwa zaka za m'ma 1900. Koma, zingakudabwitseni kudziwa kuti cellophane, kapena mapaketi a kanema wa cellulose, amapangidwa kuchokera ku zomera, kompositi, komanso "zobiriwira" zenizeni.
Kodi mapaketi a cellulose ndi chiyani?
Anapezeka mu 1833, cellulose ndi chinthu chomwe chili mkati mwa makoma a zomera. Amapangidwa ndi unyolo wautali wa mamolekyu a shuga, kuwapanga kukhala polysaccharide (mawu asayansi otanthauza chakudya).
Pamene maunyolo angapo a cellulose amalumikizana palimodzi, amapangika kukhala chinthu chotchedwa microfibrils, chomwe ndi chosasinthika komanso cholimba kwambiri. Kukhazikika kwa ma microfibrils awa kumapangitsa cellulose kukhala molekyulu yabwino kwambiri yogwiritsidwa ntchito popanga bioplastic.
Kuphatikiza apo, cellulose ndiye biopolymer yochulukira kwambiri padziko lonse lapansi, ndipo tinthu tating'onoting'ono tating'onoting'ono tachilengedwe. Ngakhale pali mitundu ingapo ya cellulose. Katundu wa cellulose chakudya nthawi zambiri amakhala cellophane, chowoneka bwino, woonda, biodegradable pulasitiki ngati zinthu.
Kodi mapaketi a filimu ya cellulose amapangidwa bwanji?
Cellophane amapangidwa kuchokera ku cellulose yotengedwa ku thonje, nkhuni, hemp, kapena zinthu zina zachilengedwe zokololedwa bwino. Zimayamba ngati zamkati zoyera zosungunuka, zomwe ndi 92% -98% cellulose. Kenako, zamkati za cellulose yaiwisi zimadutsa njira zinayi zotsatirazi kuti zisinthidwe kukhala cellophane.
1. Ma cellulose amasungunuka mu alkali (mchere woyambira, wa ayoni wamankhwala amchere achitsulo) kenako amakalamba kwa masiku angapo. Kusungunuka kumeneku kumatchedwa mercerization.
2. Mpweya wa carbon disulfide umagwiritsidwa ntchito pa zamkati za mercerized kupanga njira yotchedwa cellulose xanthate, kapena viscose.
3. Njirayi imawonjezeredwa ku chisakanizo cha sodium sulphate ndi kuchepetsa sulfuric acid. Izi zimatembenuza yankho kukhala cellulose.
4. Kenako, filimu ya cellulose imadutsanso zotsuka zina zitatu. Choyamba kuchotsa sulfure, ndiye kuti Bleach filimuyo, ndipo potsiriza kuwonjezera glycerin kwa durability.
Zotsatira zake ndi cellophane, yomwe imagwiritsidwa ntchito m'makampani ogulitsa zakudya, makamaka kupanga matumba a cellophane kapena "matumba a cello".
Ubwino wa zinthu za cellulose ndi ziti?
Ngakhale kuti njira yopangira mapaketi a cellulose ndizovuta, zopindulitsa zake ndi zomveka.
Anthu aku America amagwiritsa ntchito matumba apulasitiki 100 biliyoni pachaka, zomwe zimafunikira migolo 12 biliyoni yamafuta chaka chilichonse. Kupitilira apo, nyama zam'madzi 100,000 zimaphedwa kudzera m'matumba apulasitiki chaka chilichonse. Zimatenga zaka zoposa 20 kuti matumba apulasitiki opangidwa ndi petroleum awonongeke m'nyanja. Akatero, amapanga tinthu tating'onoting'ono tapulasitiki tomwe timalowa muzakudya.
Pamene dziko lathu likukula moganizira kwambiri za chilengedwe, tikupitirizabe kufufuza njira zogwiritsira ntchito zachilengedwe zomwe zingawonongeke m'malo mwa mapulasitiki opangidwa ndi petroleum.
Kupatula kukhala njira ina ya pulasitiki, kuyika kwa kanema wa cellulose kumapereka zabwino zambiri zachilengedwe:
Zokhazikika & zozikidwa pazachilengedwe
Chifukwa cellophane amapangidwa kuchokera ku cellulose yotengedwa ku zomera, ndi chinthu chokhazikika chochokera ku bio-based, zongowonjezwdwa.
Zosawonongeka
Makanema a cellulose amatha kuwonongeka. Mayeso awonetsa kuti mapaketi a cellulose amawonongeka m'masiku 28-60 ngati zinthuzo sizikutidwa ndi masiku 80-120 ngati zitakutidwa. Imatsikanso m'madzi m'masiku 10 ngati ili yosakutidwa komanso pafupifupi mwezi umodzi ngati itakutidwa.
Compostable
Cellophane ndiyotetezekanso kuyika mulu wanu wa kompositi kunyumba, ndipo sizifunikira malo ogulitsa kuti mupange kompositi.
Ubwino wa phukusi la chakudya:
Mtengo wotsika
Kupaka kwa cellulose kwakhalako kuyambira 1912, ndipo ndizopangidwa ndi makampani opanga mapepala. Poyerekeza ndi njira zina zapulasitiki zokomera zachilengedwe, cellophane ili ndi mtengo wotsika.
Zosamva chinyezi
Matumba a cellophane osawonongeka amakana chinyezi ndi nthunzi wamadzi, kuwapangitsa kukhala chisankho chabwino kwambiri chowonetsera ndikusunga zakudya.
Zosamva mafuta
Mwachibadwa amakana mafuta ndi mafuta, kotero matumba a cellophane ndi abwino kwa zinthu zophika, mtedza, ndi zakudya zina zamafuta.
Kutentha kotsekedwa
Cellophane ndi yotsekedwa ndi kutentha. Ndi zida zoyenera, mutha kutentha mwachangu komanso mosavuta ndikuteteza zakudya zomwe zimasungidwa m'matumba a cellophane.
Tsogolo la mapaketi a cellulose ndi chiyani?
Tsogolo lafilimu ya cellulosekuyikapo kumawoneka kowala. Lipoti la Future Market Insights likuneneratu kuti mapaketi a cellulose adzakhala ndi chiwonjezeko chapachaka cha 4.9% pakati pa 2018 ndi 2028.
Makumi 70 pa 100 alionse a kukula kumeneko akuyembekezeka kuchitika m’gawo lazakudya ndi zakumwa. Mafilimu a cellophane opangidwa ndi biodegradable cellophane ndi matumba kukhala gulu lomwe likuyembekezeredwa kwambiri.
Cellophane ndi kulongedza zakudya sizomwe zimagwiritsidwa ntchito m'mafakitale okha. Cellulose yavomerezedwa ndi FDA kuti igwiritsidwe ntchito mu:
Zakudya zowonjezera
Misozi yochita kupanga
Mankhwala filler
Chithandizo cha mabala
Cellophane imawoneka nthawi zambiri m'makampani azakudya ndi zakumwa, mankhwala, chisamaliro chamunthu, chisamaliro chapakhomo, komanso magawo ogulitsa.
Kodi zopakira za cellulose ndizoyenera bizinesi yanga?
Ngati mumagwiritsa ntchito matumba apulasitiki pamaswiti, mtedza, zinthu zophikidwa, ndi zina zotero, matumba a cellophane ndi njira ina yabwino. Opangidwa kuchokera ku utomoni wotchedwa NatureFlex™ wopangidwa kuchokera ku cellulose yochokera ku zamkati zamatabwa, matumba athu ndi amphamvu, owoneka bwino komanso ovomerezeka.
Timapereka masitayelo awiri amatumba a cellophane omwe amawonongeka mosiyanasiyana:
Matumba a cellophane
Zikwama za cellophane zagusseted
Timaperekanso chosindikizira pamanja, kuti mutha kutentha mwachangu matumba anu a cellophane.
Ku Good Start Packaging, tadzipereka kupereka matumba a cellophane apamwamba kwambiri, okoma zachilengedwe komanso ma compostable matumba. Ngati mukufuna kudziwa zambiri za mapaketi athu amakanema a cellulose kapena chilichonse mwazinthu zathu, chonde titumizireni lero
PS Onetsetsani kuti mumagula zikwama zanu za cello kuchokera kwa ogulitsa odziwika ngati Good Start Packaging. Mabizinesi ambiri amagulitsa matumba a cello "obiriwira" opangidwa kuchokera ku pulasitiki ya polypropylene.
