ʻO nā pahu pahu meaʻai he mea nui i ka hōʻoia ʻana i ka palekana o ka meaʻai a me ka maikaʻi. ʻO ke koho ʻana o nā mea e pili pono ana i ka hou o ka meaʻai, transportability, a me ka hana kaiapuni. I kēia manawa, hiki ke hoʻokaʻawale ʻia nā mea hoʻopihapiha meaʻai nui ma ka mākeke i ʻehā mau ʻāpana nui: plastic, pepa, metala, a me nā mea composite. Hāʻawi kēlā me kēia mea i nā pono noi kūikawā a me nā ʻano loea.
ʻO Polypropylene (PP), polyethylene (PE), a me ka polystyrene (PS) ka mea maʻamau maʻamau. Hoʻohana maʻamau ʻia ka PP no ka ʻeke meaʻai microwave ma muli o kona kiʻekiʻe -kūʻai wela (ma luna o 120 degere ), kiʻekiʻe ke aniani, a me ka paʻa kemika ikaika. Hāʻawi ka PE i ka maʻalahi a hoʻohana pinepine ʻia no ka ʻeke meaʻai hau. ʻO PS, ʻoiai ua hoʻohana nui ʻia i nā pahu ʻaina awakea ma muli o ke kumu kūʻai haʻahaʻa, ʻaʻole i ʻoi aku ma mua o 70 degere. ʻO nā hana hou i loko o nā plastic biodegradable, e like me ka polylactic acid (PLA), ua hoʻomaikaʻi maikaʻi i ka hana kaiapuni o ka ʻeke plastik.
Hōʻike ʻia nā pahu pahu pepa e ka pepa i uhi ʻia, ka pepa corrugated, a me ka pepa pepa meli. Hāʻawi ka pepa pepa i uhi ʻia me ka -wax pae meaʻai a i ʻole nā polymers ke kū i ka makū a me ka hiki ke paʻi ʻia, no laila e hoʻohana nui ʻia i loko o ka pāpaʻi paʻi. ʻO ka papa pepa Corrugated, mahalo i kāna hoʻolālā hoʻolālā, hāʻawi i ke kūpaʻa hoʻoemi maikaʻi loa, kūpono ia no ka lawe ʻana i ka ʻeke. Hiki ke hoʻopili pololei ʻia ka pepa kraft i mālama ʻia me nā meaʻai i kālua ʻia a hoʻokō i nā kūlana pili meaʻai EU EC 1935/2004.
ʻO nā mea metala ka mea nui o ka alumini foil a me ka tinplate. Hāʻawi ka pahu alumini alumini i nā waiwai pale maikaʻi loa (ke ālai ʻana i ke kukui, oxygen, a me nā microorganisms) a hoʻohana mau ʻia no ka ʻeke kokoleka a me nā lāʻau lapaʻau. ʻO nā kini tinplate, me nā uhi o loko a me waho, mālama i ka ikaika me ka pale ʻana i ka neʻe ʻana o ka metala kaumaha a hoʻohana pinepine ʻia no nā meaʻai hiki. Hoʻohui ʻia nā mea hoʻohuihui i nā mea maikaʻi o nā mea like ʻole ma o ka -pili papa. No ka laʻana, hāʻawi nā kiʻiʻoniʻoni alumini -paʻi kiʻiʻoniʻoni i nā mea pale a me ka maʻalahi a hoʻohana nui ʻia i ka mākaukau-e-ʻai i ka ʻeke meaʻai.
ʻO nā ʻano o kēia manawa i nā mea hoʻopili meaʻai e pili ana i ka hana a me ka hoʻomau. Ke alakaʻi nei ka ʻenehana i ka ʻoihana i ka ʻoihana palekana a ʻoi aku ka maikaʻi o ke kaiapuni.
