No ka meanā kiʻiʻoniʻoni hoʻopili meaʻaiLoaʻa iā lākou nā waiwai maikaʻi o ka pale pono ʻana i ka palekana o ka meaʻai, a hiki i kā lākou ʻike kiʻekiʻe ke hoʻonani maikaʻi i ka ʻeke, ʻoi aku ka nui o nā kiʻi ʻoniʻoni meaʻai i ka hoʻopili waiwai. I mea e hoʻokō ai i ka loli o waho o kēia manawa a me nā pono o nā mea kūʻai like ʻole, ua hoʻonui nā hui he nui a puni ka honua i kā lākou noiʻi a me ka hoʻomohala ʻana i nā kiʻi ʻoniʻoni meaʻai.
1. Kiʻiʻoniʻoni hoʻopili maʻamau
ʻO nā kiʻi ʻoniʻoni hoʻopili meaʻai maʻamau i hoʻohana pinepine ʻia i kēia manawa: PVA coated barrier film, biaxially oriented polypropylene film (BOPP), biaxially oriented polyester film (BOPET), nylon film (PA), cast polypropylene film (CPP), aluminized film, etc. hoʻohana nui ʻia ma muli o kā lākou hana maikaʻi loa, ʻike maikaʻi maikaʻi, ikaika tensile kiʻekiʻe, kekahi mau kinoea a me nā waiwai pale wai a me nā kumu kūʻai haʻahaʻa.
2. Edible packaging film
ʻO nā kiʻi ʻoniʻoni ʻai ʻai e pili ana i nā mea ʻai, ʻoi aku ka nui o nā mea macromolecular kūlohelohe e like me lipids, proteins a me polysaccharides, i hoʻohui ʻia me nā plasticizer edible, cross-linking agents, etc., i hui ʻia ma o nā hopena kino, a hoʻoponopono ʻia ma o nā ʻano hana hana like ʻole Ua hana ʻia ke kiʻiʻoniʻoni. Wahi a nā hiʻohiʻona o nā mea waiwai nui i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia nā kiʻiʻoniʻoni edible i ʻehā mau ʻāpana: nā kiʻiʻoniʻoni edible carbohydrate, protein edible films, lipid edible films, a me composite edible films. Ua hoʻohana nui ʻia nā kiʻi ʻoniʻoni hiki ke hoʻohana ʻia i ke ola o kēlā me kēia lā, e like me ka pepa laiki glutinous maʻamau i hoʻohana ʻia i loko o ka ʻeke lole, nā kīʻaha kīʻaha palaoa no ka ice cream, a me nā mea ʻē aʻe. Ke hoʻohālikelike ʻia me nā mea hoʻopili synthetic, hiki ke hoʻoheheʻe ʻia nā kiʻi ʻoniʻoni me ka ʻole o ka pollution. Me ka hoʻonui ʻana i ka ʻike kaiapuni o ka poʻe, ua lilo koke nā kiʻi ʻoniʻoni ʻai i wahi wela no ka noiʻi ʻana ma ke kahua o ka ʻeke meaʻai a loaʻa i kekahi mau hopena.
3. Kiʻiʻoniʻoni hoʻopili meaʻai antibacterial
ʻAiʻiliʻilikiʻi hoʻopaʻa meaʻaihe ʻano kiʻi ʻoniʻoni i hiki ke kāohi a pepehi paha i ka maʻi bacteria. Wahi a ke ʻano o ka antibacterial, hiki ke hoʻokaʻawale ʻia i ʻelua ʻano: antibacterial pololei a me ka antibacterial indirect. Loaʻa ka antibacterial pololei ma o ka hoʻopili pololei ʻana ma waena o nā mea hoʻopili i loaʻa nā mea antibacterial a me nā meaʻai; ʻO ka antibacterial indirect ka mea nui e hoʻohui i kekahi mau mea i ka mea lawe e hiki ke hoʻoponopono i ka microenvironment i loko o ka pōʻai, a i ʻole e hoʻohana i ka permeability koho o nā mea hoʻopili e kāohi ai i nā microorganism. ʻO ka ulu ʻana, e like me ke kiʻiʻoniʻoni hoʻopili lewa i hoʻololi ʻia.
4. Nanocomposite pahu kiʻiʻoniʻoni
ʻO ke kiʻiʻoniʻoni Nanocomposite e pili ana i kahi mea kiʻiʻoniʻoni i haku ʻia e nā ʻāpana me nā ana ma ke ʻano o nā nanometers (1-100nm) i hoʻokomo ʻia i loko o nā matrices like ʻole. Loaʻa iā ia nā mea maikaʻi o nā mea hoʻohui kuʻuna a me nā nanomaterial hou. Ma muli o ka hopena o ka ʻili, ka hopena leo, ka hopena nui a me nā ʻano ʻē aʻe i hoʻokumu ʻia e ke ʻano kūikawā o nā kiʻiʻoniʻoni nanocomposite, ko lākou ʻano optical, mechanical properties, antibacterial properties, barrier properties a me nā ʻano ʻē aʻe i loaʻa nā hiʻohiʻona i loaʻa ʻole i nā mea maʻamau. i ka ai. Hoʻohana nui ʻia ia i ka hoʻopili ʻana, ʻaʻole wale e hoʻokō i nā koi o ka hoʻonui ʻana i ke ola o ka meaʻai, akā e nānā pū i nā loli maikaʻi o ka meaʻai i loko o ka pā.
5. Biodegradable pahu kiʻiʻoniʻoni
ʻO kēia ʻano kiʻiʻoniʻoni e hoʻonā nui i ka pilikia he paʻakikī ke hana hou ʻana i kekahi mau mea hoʻopihapiha hiki ʻole ke hoʻoemi ʻia. ʻO ka kanu ʻana iā lākou ma lalo o ka lepo e hoʻopau i ke ʻano o ka lepo, a ʻo ka hoʻoulu ʻana e hoʻopuka i nā kinoea ʻawaʻawa a hoʻohaumia i ka ea. Wahi a ke ʻano o ka hoʻohaʻahaʻa ʻana, ua hoʻokaʻawale ʻia ʻo ia i ke kiʻi paʻi kiʻi photodegradable a me ke kiʻi ʻoniʻoni biodegradable.
Ma muli o ka hoʻokō ʻana o nā kiʻiʻoniʻoni degradable i nā koi palekana kaiapuni, ua aʻo nui ʻia lākou i kēia manawa a ua huki i ka manaʻo o nā mea noiʻi like ʻole. Ua hoʻomohala ʻia nā mea hoʻoheheʻe hou a me nā mea e pili ana i ke kaiapuni, e like me nā polymers i hana ʻia mai ka starch maka me ka hoʻohana ʻana i nā kumuwaiwai mea kanu hou (e like me ke kulina). Lactic acid (PLA), he plastic polypropylene carbonate (PPC) pili i ke kaiapuni i hoʻohui ʻia mai carbon dioxide a me propylene oxide ma ke ʻano he kumu, a me ka chitosan (chitosan) i loaʻa mai ka deacetylation o chitin, i ʻike nui ʻia ma ke ʻano. . Hoʻemi ʻia kēia mau waiwai waiwai; ʻaʻole hiki ke hoʻohaʻahaʻa piha ʻia nā waiwai optical, ka ʻōlinolino, a me ka ʻōlinolino. ʻAʻole wale ia e hoʻokō i ka ʻike kiʻekiʻe o nā kiʻi ʻoniʻoni, akā hoʻokani pū kekahi i ka hana ikaika i ka hoʻomaikaʻi ʻana i ke kaiapuni, a loaʻa iā ia nā manaʻo noi nui.
Eia nō naʻe, pono e haʻi ʻia he koi koʻikoʻi ka kiʻi ʻoniʻoni meaʻai i ka maʻemaʻe a me ka palekana o nā mea hoʻopihapiha, a koi i nā kūlana kūpono a me nā kaʻina hoʻāʻo. ʻOiai ua hana ʻia kekahi mau hana ma ka home a ma waho, he nui nā hemahema. . Ua hoʻomohala hou nā ʻāina ʻē i ka hoʻohana ʻana i ka ʻenehana lapaʻau plasma surface e hoʻoheheʻe iā SiOx, AlOx a me nā mea hoʻoheheʻe oxide inorganic ʻē aʻe ma nā substrate e like me PET a me BOPP e kiʻi i nā kiʻi ʻoniʻoni me nā waiwai pale kiʻekiʻe. ʻO ke kiʻiʻoniʻoni i uhi ʻia ke silicone he paʻa i ka wela a kūpono no ka kuke ʻana i ka wela wela a me ka sterilization meaʻai. ʻO nā kiʻiʻoniʻoni degradable, nā kiʻiʻoniʻoni ʻai a me nā kiʻiʻoniʻoni wai-soluble nā huahana ʻōmaʻomaʻo āpau i hoʻomohala ʻia e nā ʻāina a puni ka honua i nā makahiki i hala. ʻO ka noiʻi e pili ana i ka hoʻohana ʻana i nā polymers macromolecular kūlohelohe e like me nā lipids, nā protein a me nā sugars e like me nā kiʻiʻoniʻoni puʻupuʻu ua ulu pū kekahi.
Inā loaʻa iā ʻoe kekahi mau koi kiʻiʻoniʻoni hōʻaiʻai, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou. Ma ke ʻano he mea hana hoʻopihapiha maʻalahi ma mua o 20 mau makahiki, e hāʻawi mākou i kāu mau hoʻonā hoʻopihapiha kūpono e like me kāu pono huahana a me kāu kālā.
