Ma ke ʻano he mea paʻi, he moʻolelo pōkole ke kiʻiʻoniʻoni no nā ʻeke ʻeke meaʻai. Loaʻa iā ia nā mea maikaʻi o ka māmā, ke aniani, ka pale ʻana i ka wai, ka pale ʻana i ka oxygen, ka ea, ka paʻakikī a me ka pale ʻana, ka ʻili malū, a me ka pale o nā waiwai, a hiki iā ia ke hana hou i ke ʻano o ka huahana. a me ke kala. Me ka hoʻomohala ʻana o ka ʻoihana petrochemical, ʻoi aku ka nui o nā ʻano kiʻi ʻoniʻoni plastik. ʻO nā kiʻi ʻoniʻoni maʻamau i hoʻohana ʻia he polyethylene (PE), polyester aluminized film (VMPET), polyester film (PET), polypropylene (PP), nylon, etc.
ʻOkoʻa nā waiwai o nā kiʻiʻoniʻoni plastik like ʻole, ʻokoʻa ka paʻakikī o ka paʻi ʻana, a ʻokoʻa hoʻi ka hoʻohana ʻana e like me nā mea hoʻopili.
ʻO ka kiʻiʻoniʻoni polyethylene he mea ʻoniʻoni ʻole, ʻono ʻole, ʻono ʻole, translucent non-toxic thermal insulation material, i hoʻohana nui ʻia i ka hana ʻeke. He mea inert ia, no laila ʻoi aku ka paʻakikī o ka paʻi ʻana a pono e hana ʻia e paʻi maikaʻi.
ʻO ke kiʻi alumini i loaʻa nā hiʻohiʻona o ke kiʻiʻoniʻoni plastik a me nā ʻano metala. Hoʻopili ʻia ka ʻili o ke kiʻi me ka alumini e pale aku i ka mālamalama a me ka radiation UV, ʻaʻole ia e hoʻolōʻihi i ke ola o ka waihona, akā hoʻonui pū i ka mālamalama o ke kiʻi. Hoʻololi ia i ka alumini foil i kekahi ʻano, a loaʻa iā ia nā mea maikaʻi o ke kumu kūʻai haʻahaʻa, nā hiʻohiʻona maikaʻi a me nā waiwai pale maikaʻi. Hoʻohana nui ʻia nā kiʻiʻoniʻoni aluminized i loko o ka pahu hoʻohui. Hoʻohana nui ʻia ia i loko o ka hoʻopili ʻana i nā meaʻai maloʻo a me ka puffed e like me nā kuki, a me ka pahu waho o kekahi mau lāʻau lapaʻau a me nā mea hoʻonaninani.
ʻO ka kiʻiʻoniʻoni polyester he kala ʻole a me ka ʻike ʻole, ka moisture-proof, air-tight, soft, high-strength, resistant to acid, alkali, oil and solvent, a ʻaʻole makaʻu i ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa. Ma hope o ka mālama ʻana i ka EDM, loaʻa iā ia ka wikiwiki o ka ʻili i ka inika. No ka hoʻopili ʻana a me nā mea hoʻohui.
ʻO ke kiʻiʻoniʻoni Polypropylene he ʻōlinolino a me ka māliko, ke kūpaʻa wela, ka waika a me ke kūpaʻa alkali, ke kūpaʻa solvent, ke kū ʻana o ka abrasion, ka waimaka a me ke kinoea permeability maikaʻi. ʻAʻole hiki ke hoʻopaʻa ʻia ka wela ma lalo o 160 ° C.
ʻOi aku ka ikaika o ke kiʻi nylon ma mua o ka kiʻiʻoniʻoni polyethylene, ʻaʻala ʻole, ʻaʻohe mea ʻawaʻawa, a hiki ʻole i ka bacteria, nā aila, nā esters, ka wai paila a me ka hapa nui o nā solvents. Hoʻohana maʻamau ia no ka lawe ʻana i ka ukana, ka pale abrasion-resistant a me ka retort packaging (hoʻomaʻamaʻa ʻana i ka meaʻai) a hiki ke paʻi ʻia me ka ʻole o ka mālama ʻana.
ʻO nā ʻano paʻi no nā kiʻiʻoniʻoni plastik ʻo ia ka paʻi flexographic, paʻi gravure a me ka paʻi pale. Pono nā ʻīnika paʻi i ka viscosity kiʻekiʻe a me ka hoʻopili ikaika ʻana, no laila pili paʻa nā molekala inika i ka ʻili plastik maloʻo a maʻalahi ka hoʻokaʻawale ʻana mai ka oxygen i ka lewa a maloʻo. Ma ka laulā, ʻo ka ʻīnika no ke kiʻi ʻoniʻoni no ka paʻi gravure i haku ʻia me kahi resin synthetic e like me ka amine mua a me kahi mea hoʻoheheʻe organik i loko o ka waiʻona a me ka puaʻa ma ke ʻano nui, a ua hoʻokumu ʻia kahi ʻīnika maloʻo maloʻo ma o ka pulverization a me ka hoʻopuehu ʻana e hana i ka wai colloidal me maikaʻi fluidity. Loaʻa iā ia nā hiʻohiʻona o ka hana paʻi maikaʻi, ka hoʻopili ikaika ʻana, ke kala ʻulaʻula a me ka maloʻo wikiwiki. He kūpono no ka paʻi ʻana me ka huila paʻi concave.
Manaʻolana hiki i kēia ʻatikala ke kōkua iā ʻoe a e ʻae iā ʻoe e aʻo hou e pili ana i ka ʻeke.
