Nui nā ʻano ʻeke ʻōpala meaʻai i hoʻohana ʻia no ka ʻōpala meaʻai, a he hana kūikawā ko lākou a me nā ʻano. I kēia lā e kūkākūkā mākou i kekahi ʻike maʻamau o nā ʻeke ʻōpala meaʻai no kāu kuhikuhi. No laila he aha ka ʻeke ʻōpala meaʻai? ʻO nā ʻeke ʻōpala meaʻai e pili ana i nā plastics pepa me ka mānoanoa ma lalo o 0.25 mm e like me nā kiʻiʻoniʻoni, a ʻo ka ʻōpala palupalu i hana ʻia me nā kiʻiʻoniʻoni plastik ua hoʻohana nui ʻia i ka ʻoihana meaʻai. Nui nā ʻano ʻeke ʻōpala meaʻai. He moakaka lākou, palupalu, loaʻa ka pale wai maikaʻi, ke kūpaʻa i ka makū a me nā waiwai pale kinoea, ka ikaika mechanical maikaʻi, nā waiwai kemika paʻa, ke kūpaʻa ʻaila, maʻalahi ke paʻi nani, a hiki ke hoʻopaʻa ʻia i ka wela i loko o nā ʻeke. Eia kekahi, ʻo ka ʻōpala meaʻai palupalu i hoʻohana pinepine ʻia he ʻelua a ʻoi aku paha nā papa o nā kiʻiʻoniʻoni like ʻole, hiki ke hoʻokaʻawale ʻia i ka papa waho, ka papa waena a me ka papa o loko e like me ko lākou mau kūlana.
He aha nā koi no ka hana ʻana o kēlā me kēia papa o nā kiʻiʻoniʻoni ʻōpala meaʻai maʻalahi i hoʻohana pinepine ʻia? ʻO ka mea mua, hiki ke paʻi ʻia ka kiʻiʻoniʻoni waho, pale ʻōpala, a pale i ka pāpāho. ʻO nā mea i hoʻohana pinepine ʻia e komo pū me OPA, PET, OPP, a me nā kiʻiʻoniʻoni i uhi ʻia. ʻO ka kiʻiʻoniʻoni papa waena he mau hana e like me ke pale, ka malu māmā, a me ka pale kino. ʻO nā mea i hoʻohana pinepine ʻia e komo pū me BOPA, PVDC, EVOH, PVA, PEN, MXD6, VMPET, AL, a pēlā aku. A laila aia ka kiʻiʻoniʻoni o loko, nona nā hana o ke pale, ke sila ʻana, a me ka anti-media. ʻO nā mea i hoʻohana pinepine ʻia ʻo CPP, PE, a pēlā aku. Eia kekahi, aia kekahi mau mea i ka papa waho a me ka papa waena. No ka laʻana, hiki ke hoʻohana ʻia ʻo BOPA ma ke ʻano he papa waho no ka paʻi ʻana, a hiki ke hoʻohana ʻia ma ke ʻano he papa waena e pāʻani i kahi kuleana o ke pale a me ka pale kino.
ʻO nā ʻano kiʻiʻoniʻoni ʻōpala meaʻai maʻamau i hoʻohana ʻia, ma ke ʻano laulā, pono i ka papa waho ke kūpaʻa i ke ʻano ʻōpala, ke kūpaʻa puncture, ka pale UV, ke kūpaʻa māmā, ke kūpaʻa aila, ke kūpaʻa mea olaola, ke kūpaʻa wela a me ke anu, ke kūpaʻa i ka haki ʻana o ke koʻikoʻi, hiki ke paʻi ʻia, paʻa wela, haʻahaʻa ʻala, haʻahaʻa ʻAʻohe ʻala, ʻaʻohe ʻawaʻawa, ʻālohilohi, moakaka, malu a me nā ʻano waiwai like ʻole; pono i ka papa waena ke kūpaʻa i ka hopena, ke kūpaʻa compression, ke kūpaʻa puncture, ke kūpaʻa makū, ke kūpaʻa kinoea, paʻa ʻala, pale māmā, pale aila, ke kūpaʻa mea olaola, wela a me ke anu, ke kūpaʻa haki ʻana o ke koʻikoʻi, ikaika hui ʻelua ʻaoʻao, ʻono haʻahaʻa, haʻahaʻa ʻala, ʻaʻohe ʻawaʻawa, moakaka, pale māmā a me nā waiwai ʻē aʻe; a laila ʻo ka papa o loko, me kekahi mau waiwai maʻamau me ka papa waho a me ka papa waena, he mau waiwai kūʻokoʻa nō hoʻi, pono e loaʻa ka paʻa ʻala, haʻahaʻa adsorption a me nā waiwai anti-seepage. ʻO ka hoʻomohala ʻana o nā ʻeke ʻōpala meaʻai penei:
1. Nā ʻeke ʻōpala meaʻai i hana ʻia me nā mea pili i ke kaiapuni.
2. I mea e hōʻemi ai i nā kumukūʻai a mālama i nā kumuwaiwai, ke lahilahi nei nā ʻeke ʻōpala meaʻai.
3. Ke ulu nei nā ʻeke ʻōpala meaʻai ma ke ala o nā hana kūikawā. E hoʻomau nā mea i hui pū ʻia me nā pale kiʻekiʻe e hoʻonui i ka hiki o ka mākeke. I ka wā e hiki mai ana, ʻo nā kiʻiʻoniʻoni pale kiʻekiʻe me nā pono o ka hana maʻalahi, ka oxygen ikaika a me ka hana pale wai, a me ka hoʻomaikaʻi ʻana i ke ola papa e lilo i mea nui o ka ʻōpala meaʻai maʻalahi i nā hale kūʻai nui i ka wā e hiki mai ana.
