Palekana ʻo PP Plastic no ka mālama ʻana i ka meaʻai a me ka wela?

Ke ulu nei ka ʻike olakino, ke nānā nui nei nā mea kūʻai aku i ka palekana waiwai opahu meaʻai. Ua loaʻa i ka Polypropylene (PP) ka manaʻo ma muli o kona hoʻohana nui ʻana i nā pahu meaʻai a me ka hoʻopili. Nui ka poʻe e noʻonoʻo inā he kūpono ia no ka mālama ʻana i ka meaʻai a me ka hoʻomehana ʻana - e hōʻike ana kēia ʻatikala i ka pane.

ʻO ka Polypropylene (PP) kahi polymer thermoplastic māmā, lōʻihi, a paʻa kemika. Hāʻawi ia i ka wela maikaʻi a me ka pale ʻana i ka corrosion a hiki ke maʻalahi no ka hana ʻana, e ʻae ʻia e hana ʻia i loko o nā ʻano meaʻai like ʻole ma o ka hoʻoheheʻe ʻana, extrusion, a i ʻole ka puhi ʻana. Hiki ke hana ʻia ka ʻilika PP ma nā ʻano aniani a semi-akaka, i kūpono ia no nā pahu ʻaina awakea, nā pahu waiho ʻana, nā pāpale ʻōmole, a me nā noi hoʻopili meaʻai ʻē aʻe e koi ana i ka hoʻomaʻamaʻa a me ka nānā ʻana.

Manaʻo nui ʻia ka plastik PP ma ke ʻano he mea palekana no ka mālama ʻana i ka meaʻai ma muli o kāna mau waiwai kemika paʻa a me nā palapala hōʻoia pili meaʻai. ʻO kāna mau hiʻohiʻona nui:

• Hoʻokō me nā Kūlana Palekana Hoʻopili Meaʻai
Ua hōʻoia ʻia ka plastik PP e nā hui mana e like me ka US FDA a me ka European Union (EU), i kūpono no ka mālama pono ʻana i nā meaʻai.
• ʻAʻohe BPA a me nā mea ʻino ʻē aʻe
Hana ʻia ʻo PP me ka ʻole o nā plasticizers pōʻino maʻamau, e hōʻoiaʻiʻo ʻaʻole i hoʻokuʻu ʻia nā mea e hiki ke hoʻopilikia i ke olakino i ka wā o ka mālama ʻana i ka meaʻai.
• Ke kū'ē i nāʻakika, nā kumu, a me nāʻaila
ʻO ke ʻano molekole paʻa o PP e hiki ai ke kū i nā waikawa, nā aila, a me nā mea ʻala i ka meaʻai, mālama i ka ʻono kumu a pale i ka hōʻino ʻana o nā mea.
• Ka neʻe ʻana o nā mea haʻahaʻa
ʻO nā kaulahao molekala paʻa o PP e pale aku i nā mea hoʻohui a i ʻole nā ​​​​koena mai ka lele ʻana i loko o ka meaʻai, e hōʻoia ana i ka palekana o ka meaʻai a me ka ʻono pono.

Hōʻike ʻo PP plastic i ka hana hilinaʻi i ka wā e hoʻomehana ai i ka meaʻai ma muli o kona mau waiwai pale ʻana -wela, ma nā ʻaoʻao aʻe:

1. Kiekie -Pahana Pale
ʻO ke ʻano molekole paʻa o PP hiki iā ia ke kū i ka wela wela o ka microwave ma kahi o 110-120 degere me ka hoʻoheheʻe ʻole a wāwahi ʻole, e mālama pono ana i ka meaʻai i ka wā hoʻomehana.
2. Paʻa ʻano
ʻO nā kaulahao molekala paʻa paʻa a maʻalahi o PP e kōkua i nā ipu e mālama i ko lākou nui a me ke ʻano i ka wā e hoʻomehana ai, e pale ai i ka warping a i ʻole ka hāʻule ʻana a me ka mālama ʻana i nā papa pili meaʻai.
3. Puunaue Wela Kaulike
He haʻahaʻa ka wela o ka PP, e ʻae ana i ka wela e neʻe like i loko o ka ipu, e hōʻemi ana i nā wahi wela a kōkua i ka mālama ʻana i ke ʻano meaʻai a me nā meaʻai.
4. Ka lōʻihi
Me ke kūpaʻa wela maikaʻi loa a me ke kūpaʻa ʻana i ka ʻelemakule, mālama nā ipu PP i ko lākou ʻano a me ka hana ʻoiai ma hope o ka hoʻohana pinepine ʻana i ka microwave a i ʻole ka hoʻohana ʻana i ka mahana wela -manawa kiʻekiʻe-, e hōʻemi ana i ka pilikia o ka māhā a i ʻole ka palupalu a hoʻonui i ke ola o ka ipu.

No ka hōʻoia ʻana i ka palekana a me ka hilinaʻi o nā pahu meaʻai plastik PP i ka wā o ka mālama ʻana a me ka hoʻomehana ʻana i ka wā e hoʻolōʻihi ʻia ai ko lākou ola, ʻōlelo ʻia e hahai i kēia mau hana:

ʻO ka hōʻuluʻulu manaʻo, ʻaʻohe wela -ʻeleʻele PP, kūpaʻa, a ʻaʻohe kemika ʻino, e palekana a hilinaʻi hoʻi no ka mālama ʻana i ka meaʻai a me ka hoʻomehana ʻana. Hāʻawi ʻo YANGRUI i nā meaʻai-papa ʻilika PP i palekana no ka hoʻohana ʻana i ka microwave a kūpono hoʻi i ka mālama ʻana i nā meaʻai like ʻole a me nā pono wela. Inā makemake ʻoe, e ʻoluʻolu ekāhea iā mā˚ouno nā kikoʻī.
