Ua hoʻohana nui ʻia nā plastik i ko mākou ola i kēlā me kēia lā.Nui nā ʻano mea ʻilika.ʻIke pinepine mākou iā lākou i loko o nā pahu paʻi kiʻi paʻi kiʻi, paʻi palaki, a me nā mea ʻē aʻe / ʻO ka ʻoihana hana meaʻai kekahi o nā ʻoihana i hoʻohana nui ʻia no nā huahana plastik, no ka mea, ʻo ka meaʻai ka ʻoihana nui loa.Kokoke ia i ka waiwai o ke ola o kanaka, a ua waiwai a ākea ka ʻano meaʻai, no laila, nui nā mea hoʻohana ʻana i nā huahana palaki meaʻai, ʻoi loa i ka ʻeke o waho o ka meaʻai.
ʻO ka hoʻolauna ʻana i nā mea ʻai
PET
Hoʻohana pinepine ʻia ka plastik PET e hana i nā ʻōmole plastik, nā ʻōmole inu a me nā huahana ʻē aʻe.ʻO nā ʻōmole wai mineral plastik a me nā ʻōmole inu carbonated i kūʻai pinepine ʻia e ka poʻe, ʻo ia nā huahana pāpaʻi PET āpau, ʻo ia ka meaʻai palekana palekana.
Nā pōʻino palekana huna: He kūpono wale ka PET no ka lumi wela a i ʻole nā mea inu anu, ʻaʻole no ka meaʻai wela.Inā wela ka wela, e hoʻokuʻu ka ʻōmole i nā mea ʻawaʻawa e hoʻoulu ai i ka maʻi kanesa.Inā lōʻihi ka lōʻihi o ka hoʻohana ʻana i ka hue PET, e hoʻokuʻu koke ʻo ia i nā mea ʻawaʻawa, no laila e hoʻolei koke ʻia ka ʻōmole inu plastik ma hope o ka hoʻohana ʻana, a ʻaʻole pono e hoʻohana ʻia e mālama i nā meaʻai ʻē aʻe no ka manawa lōʻihi, i ʻole e hoʻopilikia i ke olakino. .
PP
ʻO ka plastik PP kekahi o nā plastics maʻamau.Hiki ke hana ʻia i loko o ka ʻeke plastik no kēlā me kēia huahana, e like me nā ʻeke plastik kūikawā no ka meaʻai, nā pahu plastik no ka meaʻai, nā ʻōpala no ka meaʻai, nā ʻāpana plastik no ka meaʻai, a me nā mea ʻē aʻe. kūʻē., ʻO PP wale nō ka plastic i hiki ke hoʻomehanaʻia i loko o ka umu microwave, a he kiʻekiʻe ka ikaika o ka pale pale (50,000 manawa), aʻaʻole e pōʻino ke hāʻule mai kahi kiʻekiʻe ma -20 °C.
Nā hiʻohiʻona: ʻoi aku ka paʻakikī i ka OPP, hiki ke hoʻolōʻihi ʻia (ʻelua ʻaoʻao ʻaoʻao) a laila huki ʻia i loko o kahi triangle, sila lalo a i ʻole ke sila ʻaoʻao (ʻeke envelop), mea pahu.ʻOi aku ka ʻino ma mua o ka OPP
HDPE
ʻO ka plastik HDPE, i ʻike nui ʻia he polyethylene kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ka hana ʻana, ʻoi aku ka paʻakikī, ka ikaika mechanical a me ke kūpaʻa kemika.He meaʻawaʻawaʻole a palekana a hoʻohana pinepineʻia i ka hanaʻana i nā pahu meaʻai plastic.He palupalu a hoʻohana nui ʻia no nā ʻeke ʻeke.
Nā pōʻino palekana huna: ʻAʻole maʻalahi ka hoʻomaʻemaʻe ʻana i nā ipu plastik i hana ʻia me HDPE, no laila ʻaʻole ʻōlelo ʻia ke hana hou ʻana.ʻOi aku ka maikaʻi ʻaʻole e waiho i loko o ka microwave.
LDPE
ʻO ka plastic LDPE, i ʻike mau ʻia he polyethylene low density, palupalu i ka hoʻopā ʻana.ʻO nā huahana i hana ʻia me ia nā hiʻohiʻona o ka ʻono ʻole, ʻaʻala ʻole, ʻaʻohe mea ʻawaʻawa a ʻeleʻele.Hoʻohana maʻamau i loko o nā ʻāpana plastik no ka meaʻai, kiʻiʻoniʻoni composite no ka hoʻopili ʻana i ka meaʻai, kiʻi paʻi meaʻai, lāʻau lapaʻau, pharmaceutical plastic packaging, etc.
Nā pōʻino palekana huna: ʻAʻole pale wela ka LDPE, a maʻamau, hiki ke hoʻoheheʻe wela ke ʻoi aku ka mahana ma mua o 110 °C.E like me: ʻaʻole pono e ʻōwili i ka meaʻai a ka hale i ka meaʻai a wela, i pale aku ai i ka momona o ka meaʻai mai ka hoʻoheheʻe maʻalahi ʻana i nā mea ʻino i loko o ka ʻili plastik.
Eia kekahi, pehea e koho ai i nā ʻeke plastik kūpono no ka meaʻai?
ʻO ka mea mua, ʻaʻole ʻono a ʻala ʻole nā ʻeke ʻeke plastik no ka meaʻai ke haʻalele lākou i ka hale hana;ʻAʻole hiki ke hoʻohana ʻia nā ʻeke ʻeke pepa me nā mea ʻala kūikawā no ka mālama ʻana i ka meaʻai.ʻO ka lua, ʻaʻole hiki ke hoʻohana ʻia nā ʻeke ʻeke pepa kala (e like me ka ʻulaʻula ʻeleʻele a ʻeleʻele paha ma ka mākeke) no nā ʻeke plastik meaʻai.No ka mea, ua hana pinepine ʻia kēia mau ʻano ʻeke ʻeke pepa i nā ʻōpala i hoʻohana hou ʻia.ʻO ke kolu, ʻoi aku ka maikaʻi o ke kūʻai ʻana i nā ʻeke plastik no ka meaʻai ma nā hale kūʻai nui, ʻaʻole nā hale kūʻai alanui, no ka mea ʻaʻole i hōʻoiaʻiʻo ʻia ka lako o nā waiwai.
