Udindo Waukulu wa Zokhazikika za Madzi mu Mafilimu Omwe Amawonetsa Chakudya

Mu gawo la kusintha kwa ma CD a chakudya, komwe chitetezo, nthawi yosungiramo zinthu, komanso kukhulupirika kwa zinthu zimagwirizana, zinthu zokhazikika zamadzimadzi zakhala ngati ngwazi zosayamikirika. Zowonjezera izi, zopangidwa mwaluso kwambiri kuti zigwiritsidwe ntchito m'mafilimu apamwamba, zimagwira ntchito zosiyanasiyana zomwe ndizofunikira kwambiri pa thanzi la ogula komanso magwiridwe antchito a mafakitale. Tiyeni tifufuze ntchito zinayi zazikulu zomwe zimapangitsa kuti zinthu zokhazikika zamadzimadzi zikhale zofunika kwambiri m'ma CD amakono a chakudya.

Kulimba Mtima pa Kutentha: Kuteteza Mafilimu ku Kutentha Koyambitsidwa ndi KutenthaKuwonongeka kwa mbiri

Makanema opangidwa ndi chakudya, kaya ndi polyethylene (PE) kapena polypropylene (PP), amakonzedwa kutentha kwambiri (monga kutulutsa, kupopera) mpaka 230°C.Zokhazikika zamadzimadziamagwira ntchito ngati oteteza kutentha, kuteteza ma free radicals omwe amapangidwa panthawi ya kutentha. Kafukufuku wopangidwa ndi Institute of Packaging Technologies adapeza kuti popanda zolimbitsa thupi, zitsanzo za filimu zinawonetsa kuchepa kwa 35% kwa mphamvu yokoka pambuyo pa mphindi 10 pa 200°C. Mosiyana ndi zimenezi,mafilimu okhala ndi chokhazikika chamadzimadzi chokonzedwa bwinoMa formulations amasunga mphamvu zawo zopitirira 90%, zomwe zimaonetsetsa kuti kapangidwe kake kamakhala koyenera pophika monga ma tray ophikira mu microwave.

Kutalikitsa Moyo wa Shelf: Kuchepetsa Oxidation ndi Kuwonongeka kwa UV​

Kupatula kukonza, zolimbitsa thupi zamadzimadzi zimalimbana ndi zinthu zomwe zimawononga chilengedwe panthawi yosungira ndi kunyamula. Kuwala kwa UV ndi mpweya woipa zimatha kuyambitsa kuwala kwa dzuwa, zomwe zimapangitsa kuti mafilimu akhale achikasu komanso ofooka. Mwachitsanzo, poyesa koyerekeza pa phukusi la mbatata, mafilimu okhala ndi zowonjezera zamadzimadzi zolimbitsa UV amawonjezera kutsitsimuka kwa zinthu ndi 25%, monga momwe zimayesedwera ndi mtengo wa peroxide. Ma antioxidants okhala ndi mafuta acid m'zolimbitsa thupi zamadzimadzi amachotsa mpweya, pomwe zolimbitsa thupi za UV monga benzotriazoles zimateteza mafilimu ku kuwonongeka kwa kuwala, kusunga kukongola kwa phukusi komanso thanzi la chakudya.

Kuthekera kwa kukonzaKupititsa patsogolo: Kukonza Kuthamanga kwa Melt ndiKufanana

Opanga akukumana ndi zovuta kuti akwaniritse makulidwe ofanana a filimu ndi kutha kwa pamwamba. Zolimbitsa madzi zimachepetsa kukhuthala kwa kusungunuka ndi 18%, malinga ndi malipoti a makampani, zomwe zimapangitsa kuti kutulutsa kukhale kosalala. Kusintha kumeneku ndikofunikira kwambiri pakupanga mizere yothamanga kwambiri, komwe kusiyana kwa makulidwe a 0.1 mm kungayambitse zinyalala zambiri. Mwa kulimbikitsa kupangidwa kwa pulasitiki nthawi zonse, zolimbitsa thupi zimachepetsa zolakwika monga kusinthasintha kwa pamwamba ndi makulidwe a sharkskin, zomwe zimapangitsa kuti ndalama zisungidwe bwino komanso kuti ntchito ikhale yabwino.

Kutsatira Malamulo: Kuonetsetsa Kuti Chakudya Chili ndi Chitetezo kwa OgulaKudalira

Chitetezo cha mafilimu opangidwa ndi chakudya chimadalira pa kayendetsedwe ka zinthu zowonjezera. Zolimbitsa thupi zamadzimadzi ziyenera kutsatira malamulo okhwima, monga US FDA 21 CFR 178.2010 ndi EU Regulation (EC) No 10/2011. Mwachitsanzo,zokhazikika za calcium-zinc, yovomerezeka ngati njira zina zopanda poizoni m'malo mwa mankhwala achikhalidwe okhala ndi lead, ikutsatira miyezo yapadziko lonse lapansi ya zinthu zokhudzana ndi chakudya. Kusamuka kwawo kochepa (≤0.1 ppm pa zitsulo zolemera) kumawapangitsa kukhala abwino kwambiri popaka chakudya cha ana, komwe chitetezo chimakhala chofunikira kwambiri.

Malo Amtsogolo: Zatsopano mu Ukadaulo Wokhazikika​

Makampaniwa akusintha kupita ku zinthu zokhazikika zamadzimadzi zochokera ku zinthu zachilengedwe. Mafuta a soya opangidwa ndi epoxidized, ochokera kuzinthu zongowonjezwdwanso, tsopano ndi 30% ya msika wa zinthu zokhazikika zomwe siziwononga chilengedwe. Ofufuza akufufuzanso mitundu yosiyanasiyana yophatikiza kukhazikika ndi zinthu zogwira ntchito, monga mphamvu zophera tizilombo toyambitsa matenda. Kupita patsogolo kumeneku kukulonjeza kufotokozeranso njira zotetezera chakudya komanso zokhazikika.

Pomaliza, zinthu zokhazikika zamadzimadzi sizinthu zowonjezera chabe koma ndi zinthu zofunika kwambiri zomwe zimateteza kuphatikizika kwa chakudya, zimapangitsa kuti kupanga chakudya kukhale kosavuta, komanso kutsata malamulo. Pamene kufunikira kwa ogula kuti apange ma CD otetezeka komanso okhalitsa kukukula, zinthu zosiyanasiyanazi zipitilizabe kusintha, zomwe zikuyambitsa luso la kupanga chakudya.
