Ua māhele ʻia nā palakiko papa meaʻai i: PET (polyethylene terephthalate), HDPE (polyethylene density kiʻekiʻe), LDPE (polyethylene density haʻahaʻa), PP (polypropylene), PS (polystyrene), PC a me nā ʻano ʻē aʻe

PET (polyethylene terephthalate)

Nā hoʻohana maʻamau: nā ʻōmole wai mineral, nā ʻōmole inu kalapona, a pēlā aku.
Hana ʻia nā ʻōmole wai mineral a me nā ʻōmole inu kalapona me kēia mea. ʻAʻole hiki ke hana hou ʻia nā ʻōmole inu no ka wai wela, a kūpaʻa kēia mea i ka wela a hiki i 70°C. He kūpono wale nō ia no nā mea inu mehana a hau paha, a maʻalahi ke hoʻololi ʻia ke hoʻopiha ʻia me nā wai wela kiʻekiʻe a i ʻole i hoʻomehana ʻia, me nā mea ʻino i ke kanaka e puka mai ana. Eia kekahi, ua ʻike nā kānaka ʻepekema ma hope o 10 mau mahina o ka hoʻohana ʻana, hiki i kēia huahana plastik ke hoʻokuʻu i nā carcinogens he mea ʻawahia i ke kanaka.

No kēia kumu, pono e hoʻolei ʻia nā ʻōmole inu ke pau a ʻaʻole hoʻi e hoʻohana ʻia ma ke ʻano he kīʻaha a i ʻole nā ​​ipu mālama no nā mea ʻē aʻe e pale aku ai i nā pilikia olakino.
Ua hoʻohana mua ʻia ʻo PET ma ke ʻano he olonā synthetic, a me ke kiʻiʻoniʻoni a me ka lipine, a i ka makahiki 1976 wale nō i hoʻohana ʻia ai i loko o nā ʻōmole inu. Ua hoʻohana ʻia ʻo PET ma ke ʻano he mea hoʻopiha i ka mea i ʻike nui ʻia ʻo 'ʻōmole PET'.

He paʻakikī a paʻakikī hoʻi ka ʻōmole PET, he māmā (1/9 a 1/15 wale nō o ke kaumaha o kahi ʻōmole aniani), maʻalahi ke lawe a hoʻohana, hoʻopau i ka ikehu liʻiliʻi i ka hana ʻana, a he impermeable, ʻaʻole e hū a kū i nā waikawa a me nā alkalis.

I nā makahiki i hala iho nei, ua lilo ia i ipu hoʻopiha koʻikoʻi no nā mea inu kalapona, kī, wai huaʻai, wai inu i hoʻopaʻa ʻia, waina a me ka mea ʻono soy, a pēlā aku. Eia kekahi, ua hoʻohana nui ʻia nā mea hoʻomaʻemaʻe, nā shampoos, nā ʻaila meaʻai, nā mea ʻono, nā mea ʻono, nā lāʻau lapaʻau, nā mea hoʻonani, a me nā mea inu ʻona i loko o nā ʻōmole hoʻopili.

HDPE(Polyethylene Density Kiʻekiʻe)

Nā hoʻohana maʻamau: nā huahana hoʻomaʻemaʻe, nā huahana ʻauʻau, a pēlā aku.
ʻO nā ipu palaki no nā huahana hoʻomaʻemaʻe, nā huahana ʻauʻau, nā ʻeke palaki i hoʻohana ʻia ma nā hale kūʻai nui a me nā hale kūʻai kūʻai, ua hana nui ʻia me kēia mea, hiki ke kū i ka mahana kiʻekiʻe o 110 ℃, i hōʻailona ʻia me ka meaʻai hiki ke hoʻohana ʻia nā ʻeke palaki e paʻa i ka meaʻai. Hiki ke hoʻohana hou ʻia nā ipu palaki no nā huahana hoʻomaʻemaʻe a me nā huahana ʻauʻau ma hope o ka hoʻomaʻemaʻe pono ʻana, akā ʻaʻole i hoʻomaʻemaʻe maikaʻi ʻia kēia mau ipu, e waiho ana i nā koena o nā huahana hoʻomaʻemaʻe mua, e hoʻolilo ana iā lākou i wahi hānau no ka bacteria a me ka hoʻomaʻemaʻe piha ʻole, no laila ʻoi aku ka maikaʻi o ka hana hou ʻole ʻana iā lākou.
ʻO PE ka palakika i hoʻohana nui ʻia ma ka ʻoihana a me ke ola, a ua māhele ʻia i ʻelua ʻano: polyethylene kiʻekiʻe-density (HDPE) a me ka polyethylene haʻahaʻa-density (LDPE). ʻOi aku ka kiʻekiʻe o ka hoʻoheheʻe ʻana o HDPE ma mua o LDPE, ʻoi aku ka paʻakikī a ʻoi aku ka pale ʻana i ka ʻino ʻana o nā wai ʻino.

Ua ʻike nui ʻia ka LDPE i ke ola o kēia au, ʻaʻole naʻe no nā ipu i hana ʻia ai, akā, no nā ʻeke palakika hiki ke ʻike ʻia ma nā wahi a pau. Hana ʻia ka hapa nui o nā ʻeke palakika a me nā kiʻiʻoniʻoni me ka LDPE.

LDPE (Polyethylene Density Haʻahaʻa)

Nā hoʻohana maʻamau: ʻili paʻa, a pēlā aku.
Hana ʻia nā ʻili ʻili, nā ʻili plastik, a me nā mea ʻē aʻe me kēia mea. ʻAʻole ikaika ke kūpaʻa wela, ʻo ka maʻamau, ʻo ka ʻili PE kūpono i ka mahana ma luna o 110 ℃ e ʻike ʻia he hanana heheʻe wela, e waiho ana i kekahi kino kanaka ʻaʻole hiki ke palaho i ka mea palakiko. Eia kekahi, i ka wā e hoʻomehana ʻia ai ka meaʻai i loko o ka ʻili ʻili, hiki i ka momona i loko o ka meaʻai ke hoʻoheheʻe maʻalahi i nā mea ʻino i loko o ka ʻili. No laila, he mea nui e wehe mua i ka ʻōwili plastik mai ka meaʻai i loko o ka microwave.

PP (polypropylene)

Nā hoʻohana maʻamau: nā pahu ʻaina microwave
Hana ʻia nā pahu ʻaina awakea microwave me kēia mea, he mea kūpaʻa i 130°C a he ʻano moakaka ʻole. ʻO kēia wale nō ka pahu plastik hiki ke hoʻokomo ʻia i loko o ka microwave a hiki ke hoʻohana hou ʻia ma hope o ka hoʻomaʻemaʻe pono ʻana.

He mea nui e hoʻomaopopo ʻia ua hana ʻia kekahi mau pahu microwave me PP 05, akā ua hana ʻia ke poʻi me PS 06, nona ka moakaka maikaʻi akā ʻaʻole kūpaʻa i nā mahana kiʻekiʻe, no laila ʻaʻole hiki ke waiho ʻia i loko o ka microwave me ka pahu. I mea e palekana ai, e wehe i ke poʻi ma mua o ke kau ʻana i ka pahu i loko o ka microwave.
Hiki ke ʻōlelo ʻia ʻo PP lāua ʻo PE he mau hoahānau ʻelua, akā ʻoi aku ka maikaʻi o kekahi mau waiwai kino a me ka mechanical ma mua o PE, no laila hoʻohana pinepine nā mea hana ʻōmole iā PE e hana i ke kino o ka ʻōmole, a hoʻohana iā PP me ka paʻakikī a me ka ikaika nui e hana i ka pāpale a me ka lima.

He kiʻekiʻe ke kiko heheʻe o ka PP he 167°C a he kūpaʻa i ka wela, a hiki ke hoʻomaʻemaʻe ʻia kāna mau huahana i ka mahu. ʻO nā ʻōmole maʻamau i hana ʻia mai PP he waiū soy a me nā ʻōmole waiū laiki, a me nā ʻōmole no ka wai huaʻai maʻemaʻe 100%, yogurt, nā mea inu wai, nā huahana waiū (e like me ka pudding), a pēlā aku. ʻO nā ipu nui, e like me nā bākeke, nā ʻōpala, nā poho holoi lole, nā hīnaʻi, nā hīnaʻi, a pēlā aku, ua hana nui ʻia mai PP.

PS (polystyrene)

Nā hoʻohana maʻamau: nā kīʻaha o nā pahu noodle, nā pahu meaʻai wikiwiki
ʻO ka mea i hoʻohana ʻia no ka hana ʻana i nā kīʻaha noodles a me nā pahu meaʻai wikiwiki huʻa. He kūpaʻa ia i ka wela a me ke anu, akā ʻaʻole hiki ke waiho ʻia i loko o ka umu microwave e pale aku i ka hoʻokuʻu ʻia ʻana o nā kemika ma muli o ke kiʻekiʻe o ka mahana. ʻAʻole pono e hoʻohana ʻia no nā waikawa ikaika (e like me ka wai ʻalani) a i ʻole nā ​​​​mea alkaline, no ka mea, ʻo ka polystyrene, he mea maikaʻi ʻole ia no ke kanaka, hiki ke pala. No laila, pono ʻoe e pale i ka hoʻopaʻa ʻana i ka meaʻai wela i loko o nā pahu meaʻai wikiwiki i ka hiki.
He haʻahaʻa ka omo ʻana o ka wai o PS a he paʻa kona ana, no laila hiki ke hoʻoheheʻe ʻia, kaomi ʻia, hoʻopuka ʻia a i ʻole hoʻomehana ʻia. Hiki ke hoʻoheheʻe ʻia, hoʻopuka ʻia, hoʻopuka ʻia a hoʻomehana ʻia. Hoʻokaʻawale pinepine ʻia ia he hua a i ʻole ʻaʻole hua e like me ka mea i hala i ke kaʻina hana "hua".

PCa me nā mea ʻē aʻe

Nā hoʻohana maʻamau: nā ʻōmole wai, nā kīʻaha, nā ʻōmole waiū
He mea hoʻohana nui ʻia ka PC, ʻoi aku hoʻi i ka hana ʻana i nā ʻōmole waiū a me nā kīʻaha hakahaka, a he mea hoʻopaʻapaʻa no ka mea aia iā ia ʻo Bisphenol A. Kuhikuhi nā loea ma ke kumumanaʻo, inā e hoʻololi ʻia ka BPA 100% i loko o ke ʻano palakiko i ka wā o ka hana ʻana o PC, ʻo ia hoʻi, ʻaʻohe BPA o ka huahana, ʻaʻole e haʻi aku ʻaʻole ia e hoʻokuʻu ʻia. Eia nō naʻe, inā ʻaʻole i hoʻololi ʻia kahi liʻiliʻi o ka BPA i loko o ke ʻano palakiko o PC, hiki ke hoʻokuʻu ʻia i loko o ka meaʻai a i ʻole nā ​​​​mea inu. No laila, pono e mālama pono i ka wā e hoʻohana ai i kēia mau ipu palakiko.
ʻO ke kiʻekiʻe o ka mahana o ka PC, ʻo ka nui o ka BPA e hoʻokuʻu ʻia a ʻo ka wikiwiki hoʻi e hoʻokuʻu ʻia. No laila, ʻaʻole pono e lawelawe ʻia ka wai wela i loko o nā ʻōmole wai PC. Inā ʻo kāu ipu hao he helu 07, hiki i kēia mau mea ke hōʻemi i ka pilikia: Mai hoʻomehana iā ia i ka wā e hoʻohana ʻia ai a mai hoʻokuʻu iā ia i ka lā pololei. Mai holoi i ka ipu hao i loko o ka mea holoi kīʻaha a i ʻole ka mea holoi kīʻaha.

Ma mua o ka hoʻohana mua ʻana, e holoi me ka soda baking a me ka wai mahana a hoʻomaloʻo maoli iā ia ma ka mahana o ka lumi. He mea kūpono ke hoʻōki i ka hoʻohana ʻana i ka ipu inā he mau kulu a haki paha, no ka mea, hiki i nā huahana plastik ke loaʻa maʻalahi nā bacteria inā he ʻili lahilahi ko lākou. E pale i ka hoʻohana hou ʻana i nā mea hana plastik i pala.
