I ka ulu wikiwiki ʻana o ka ʻoihana meaʻai, Kiʻiʻoniʻoni Puke Hau , ma ke ʻano he kumu nui e pale ai i ka hou o ka meaʻai a hoʻolōʻihi i ke ola o ka mālama ʻana, ke loaʻa nei ka manaʻo nui aʻe. Me ka holomua o ka ʻenehana a me ka hoʻololi ʻana o ka makemake o nā mea kūʻai aku, ua puka mai nā ʻano mea kiʻi ʻoniʻoni paʻa paʻa hau nui ma ka mākeke, kēlā me kēia me kona ʻano ponoʻī a me nā pono.

1. Polyethylene (PE) i hoʻopaʻa ʻia i ka pahu pahu hau
ʻO ka polyethylene (PE) kekahi o nā mea i hoʻohana pinepine ʻia i loko kiʻi paʻi paʻa hau . Loaʻa iā ia nā waiwai mechanical maikaʻi, ke kūpaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa kemika, a hiki ke mālama i ka hana paʻa ma luna o kahi ākea ākea. ʻO ka kiʻi ʻoniʻoni paʻa paʻa paʻa PE-based maʻamau he ʻano ʻāpana-layer, e hui pū ana i nā papa waiwai me nā hana like ʻole ma o ka ʻenehana co-extrusion e hoʻomaikaʻi ai i nā waiwai pale, ke kūpaʻa puncture a me nā waiwai sealing wela. He haʻahaʻa ke kumu kūʻai a maʻalahi kēia mea hana, a hoʻohana nui ʻia i loko o ka paʻi ʻana o ka ʻiʻo hau, ka iʻa, nā huaʻai a me nā meaʻai a me nā meaʻai ʻē aʻe.

2. Polyvinylidene chloride (PVDC) kiʻi paʻi paʻi paʻa hau
ʻIke ʻia ʻo Polyvinylidene chloride (PVDC) paʻi kiʻi ʻoniʻoni maloʻo no kāna mau mea pale maikaʻi loa. ʻO ke kiʻiʻoniʻoni PVDC kahi mana pale ikaika no ka oxygen, ka wai wai, ka ʻala a me ka ʻala, a hiki ke pale maikaʻi i ka meaʻai mai ka mana o ke kaiapuni o waho. Eia kekahi, loaʻa i ka PVDC kiʻi ʻoniʻoni maikaʻi ka hoʻopaʻa ʻana i ka wela a me ke kūpaʻa haʻahaʻa haʻahaʻa, a hiki ke mālama i ka hana paʻa ma lalo o nā kūlana hau. Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke kiʻi ʻoniʻoni PVDC, a he paʻakikī ke kaʻina hana hou, kahi e kaupalena ʻia ai kāna palapala noi i kekahi ʻano.

3. ʻO ke kiʻiʻoniʻoni hoʻopaʻa paʻa ʻo Nylon
Ua ʻike ʻia ke kiʻi ʻoniʻoni paʻa paʻa ʻo Nylon no kona ikaika kiʻekiʻe, paʻakikī kiʻekiʻe a me ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi. ʻO ke kiʻi ʻoniʻoni ʻo Nylon ka maikaʻi o ka puncture a me ka waimaka, hiki ke pale pono i ka meaʻai i loko o ka pōʻai mai ka pōʻino kino. Eia kekahi, loaʻa i ke kiʻi ʻoniʻoni ʻo nylon nā waiwai pale maikaʻi, hiki ke pale i ke komo ʻana o ka oxygen a me ka mahu wai. Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke kiʻi ʻoniʻoni nylon, a hoʻohana maʻamau ia i ka mākeke meaʻai kiʻekiʻe me nā koi kiʻekiʻe no ka hana ʻana.

4. Ethylene-vinyl alcohol copolymer (EVOH) kiʻi paʻi paʻi paʻa
ʻO ka Ethylene-vinyl alcohol copolymer (EVOH) kahi mea pale hana kiʻekiʻe i hoʻohana nui ʻia i loko o ke kiʻi ʻoniʻoni hau. Loaʻa i ke kiʻi ʻoniʻoni EVOH nā mea pale maikaʻi e kūʻē i ka oxygen a me ka mahu wai, a hiki ke hoʻolōʻihi i ke ola o ka meaʻai. Ma ka manawa like, loaʻa ka kiʻi ʻoniʻoni EVOH i ka hana hoʻoponopono maikaʻi a me ke kūpaʻa wela, a hiki ke hoʻopili pū ʻia me nā ʻano mea like ʻole e hana i kahi kiʻiʻoniʻoni paʻa paʻa multifunctional. Eia nō naʻe, pipiʻi a paʻakikī ke kiʻi ʻoniʻoni EVOH i ka haʻahaʻa, a pono e mālama a mālama ʻia ma lalo o nā kūlana maloʻo.

5. Polypropylene (PP) kiʻi paʻi paʻi hau
Polypropylene (PP) kiʻi paʻi paʻa hau makemake ʻia no kona ʻano ʻike maikaʻi, kūpaʻa wela a me ke kūpaʻa haʻahaʻa haʻahaʻa. ʻO ka kiʻiʻoniʻoni PP he kiʻekiʻe rigidity a me ka ʻoʻoleʻa, a kūpono ia no ka paʻi ʻai meaʻai maloʻo e koi ai i kekahi ikaika kākoʻo. Eia kekahi, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka wela a me ka hana hou ʻana o ka kiʻiʻoniʻoni PP, e hoʻokō ana i nā koi o ka mālama kaiapuni. Eia nō naʻe, nāwaliwali nā waiwai pale o ka kiʻiʻoniʻoni PP i ka oxygen a me ka mahu wai, a he mea maʻamau ia e hoʻomaikaʻi i kāna mau mea pale ma o ka ʻenehana co-extrusion multi-layer.

Ka manaʻo nui kiʻi paʻi paʻa hau ʻO nā mea ma ka mākeke o kēia manawa he polyethylene (PE), polyvinylidene chloride (PVDC), nylon (Nylon), ethylene-vinyl alcohol copolymer (EVOH) a me polypropylene (PP). Loaʻa i kēlā me kēia mea nā hiʻohiʻona ponoʻī a me nā mea maikaʻi, kūpono no nā pono ʻai meaʻai like ʻole. Me ka holomua o ka ʻenehana a me ka hoʻololi ʻana o nā pono o nā mea kūʻai aku, e hoʻomau ka neʻe ʻana o nā mea kiʻi ʻoniʻoni paʻa hau i ka hana kiʻekiʻe, ka mālama ʻana i ke kaiapuni a me ka hoʻomohala hoʻomau i ka wā e hiki mai ana. E hoʻomau ka poʻe hana i ka ʻimi ʻana i nā mea hou, nā kaʻina hana hou a me nā noi hou e hoʻokō i ka noi mākeke no nā kiʻi ʻoniʻoni paʻa hau kiʻekiʻe.
