Ua hoʻomohala wikiwiki ʻia nā mea hoʻopihapiha pale pale kiʻekiʻe a hoʻohana nui ʻia i ka ʻoihana paʻi ʻoi loa i ka ʻoihana meaʻai.He kuleana ko ia i ka mālama ʻana i ka maikaʻi o ka meaʻai, ka mālama hou ʻana, ka mālama ʻono a me ka hoʻonui ʻana i ke ola.Loaʻa nā ʻenehana like ʻole no ka mālama ʻana i ka meaʻai, e like me ka pahu vacuum, ka hoʻoneʻe ʻana o ke kinoea, ka hoʻopaʻa ʻana i ka deoxidizer packaging, ka mea maloʻo meaʻai, ka aseptic filling packaging, ke kuke kuke ʻana, ka wai hoʻopihapiha hoʻopihapiha wai a pēlā aku.I loko o ka nui o kēia mau ʻenehana hoʻopili, pono e hoʻohana ʻia nā mea hoʻopihapiha palaki maikaʻi.
ʻO nā mea kiʻiʻoniʻoni pale kiʻekiʻe maʻamau e like me kēia:
1. Mea PVDC (Polyvinylidene Chloride)
ʻO ka polyvinylidene chloride (PVDC) resin, i hoʻohana pinepine ʻia e like me nā mea hoʻohui a i ʻole nā mea monomer a me nā kiʻiʻoniʻoni co-extruded, ʻo ia ka mea i hoʻohana nui ʻia i nā mea hoʻopili pale pale kiʻekiʻe.ʻOi aku ka nui o ka hoʻohana ʻana i ka PVDC coated film.ʻO ke kiʻi i uhi ʻia ʻo PVDC ka hoʻohana ʻana i ka polypropylene (OPP), polyethylene terephthalate (PET) ma ke ʻano kumu.Ma muli o ke kiʻekiʻe palupalu o ka PVDC maʻemaʻe, kokoke ka solubility o PVDC i kona wela decomposition, a ʻilihune ka miscibility me ka plasticizer maʻamau, paʻakikī a paʻakikī ka hoʻopili pololei ʻana.ʻO ka hoʻohana maoli ʻana i ka kiʻiʻoniʻoni PVDC ka hapa nui o ka copolymer o vinylidene chloride (VDC) a me ka vinyl chloride (VC), a me ka acrylic methylene (MA) copolymerization i hana ʻia me ke kiʻi pale pale maikaʻi loa.
2. Nailon Packaging Materials
Ma mua o ka hoʻohana ʻana i nā mea hoʻopaʻa naylon - hoʻohana pololei i ka "nylon 6".Akā ʻaʻole kūpono ka paʻa ʻana o ka ea "nylon 6".ʻO ka nylon (MXD6) i hana ʻia mai ka polycondensation o ka m-dimethylamine a me ka adipic acid he 10 mau manawa ʻoi aku ka paʻa o ka ea ma mua o "nylon 6", ʻoiai ʻoi aku ka maikaʻi o ke aniani a me ke kūpaʻa ʻana.Hoʻohana nui ʻia no ke kiʻiʻoniʻoni pale pale kiʻekiʻe no nā koi pale kiʻekiʻe o ka paʻi paʻa meaʻai.Ua ʻae ʻia e ka FDA no ka hoʻomaʻemaʻe meaʻai.ʻO kāna hiʻohiʻona nui loa ma ke ʻano he kiʻiʻoniʻoni ʻaʻole e hāʻule ka pale me ka piʻi ʻana o ka haʻahaʻa.Ma ʻEulopa, hoʻohana nui ʻia ʻo MXD6 nylon ma ke ʻano he ʻokoʻa i nā kiʻiʻoniʻoni PVDC ma muli o nā pilikia palekana kūlohelohe.
3. Na Mea EVOH
ʻO EVOH ka mea i hoʻohana nui ʻia i nā mea pale kiʻekiʻe.
ʻO nāʻano kiʻiʻoniʻoni o kēia mea i hoʻohuiʻia i keʻano non-tensile, aia nāʻano tensileʻelua, keʻano hoʻoheheʻe alumini, keʻano o ka uhiʻana a me nā mea'ē aʻe.ʻElua ala hoʻolōʻihi a me nā huahana pale wela no ka ʻeke aseptic.
4. Kiʻiʻoniʻoni i uhi ʻia i ka ʻokiʻoki kino
ʻO ka PVDC, ka mea i hoʻohana nui ʻia ma ke ʻano he mea hoʻopihapiha pale pale kiʻekiʻe, hiki ke hoʻololi ʻia e nā mea hoʻopihapiha ʻē aʻe no ka mea e hoʻopuka ka ʻōpala i ka HCl ke puhi ʻia.No ka laʻana, ua hoʻolohe ʻia ka mea i kapa ʻia i uhi ʻia ma hope o ka uhi ʻana o SiOX (silicon oxide) ma ke kiʻi o nā substrates ʻē aʻe, ma waho aʻe o ke kiʻi ʻoniʻoni silicon oxide, aia nā alumina evaporation film.ʻO ka hana paʻa kinoea o ka uhi ʻana ua like ia me ka mea o ka silicon oxide i loaʻa ma ke ʻano like.
I nā makahiki i hala iho nei, ua ulu wikiwiki nā ʻenehana multilayer composite, blending, copolymerization a me evaporation.Ua hoʻomohala hou ʻia nā mea hoʻopihapiha pale pale kiʻekiʻe e like me vinyl vinyl glycol copolymer (EVOH), polyvinylidene chloride (PVDC), polyamide (PA), polyethylene terephthalate (PET) multilayer composite material a me ka silicon oxide compound evaporation film, ʻoi aku ka nui o nā huahana aʻe. makaʻala: MXD6 polyamide mea hoʻopili;Polyethylene glycol naphthalate (PEN);Silicon oxide evaporation film, etc.
