ʻO ke kiʻi paʻi kiʻi CA he aniani, ʻālohilohi, a he ʻili malū. He ʻoʻoleʻa, paʻa ka nui, ʻaʻole maʻalahi ka hōʻiliʻili ʻana i ka uila, a maikaʻi ka hana; Maʻalahi e hoʻopaʻa a paʻi maikaʻi. A loaʻa iā ia ka pale wai, ka pale ʻana a me ka paʻa. He kiʻekiʻe ke kiʻekiʻe o ka ea a me ka moisture permeability o CA packaging film, hiki ke hoʻohana ʻia no ka "hanu" ʻana o nā mea kanu, nā huaʻai, a me nā mea ʻē aʻe.
Hoʻohana pinepine ʻia ka kiʻi ʻoniʻoni CA packaging ma ke ʻano he papa waho o ka kiʻiʻoniʻoni composite ma muli o kona helehelena maikaʻi a me ka maʻalahi o ka paʻi ʻana. Hoʻohana nui ʻia kāna kiʻi ʻoniʻoni composite no ka hoʻopili ʻana i nā lāʻau lapaʻau, nā meaʻai, nā mea hoʻonaninani a me nā mea ʻē aʻe.

13. Ionic hoʻopaʻa polimerʻōwili pahu kiʻiʻoniʻoni

ʻOi aku ka maikaʻi o ke kiʻi ʻoniʻoni polymer i hoʻopaʻa ʻia i ka ion ma mua o ka kiʻiʻoniʻoni PE, a ʻaʻohe mea ʻawaʻawa. Loaʻa iā ia ka paʻa o ka ea, ka palupalu, ka lōʻihi, ka pale ʻana i ka puncture, a me ka pale ʻaila. He kūpono no ka hoʻopili ʻana i nā mea angular a me ka ʻeke wela o ka meaʻai. He maikaʻi kāna hana hoʻopaʻa wela haʻahaʻa, ākea ka laulā wela o ka wela, a maikaʻi mau ka hana hoʻopaʻa ʻana me ka hoʻopili ʻana, no laila ua hoʻohana mau ʻia ʻo ia e like me kahi papa hoʻopaʻa wela no nā kiʻi ʻoniʻoni composite. Eia kekahi, loaʻa i nā polymers i hoʻopaʻa ʻia i ka ion adhesion thermal maikaʻi a hiki ke hoʻopili ʻia me nā plastics ʻē aʻe e hana i nā kiʻiʻoniʻoni composite.
