| Hana wela | Ke kūpaʻa wela kiʻekiʻe, hiki ke hoʻomehana ʻia i loko o ka microwave e hoʻomehana iā PP, hoʻohana i ka mahana: -30℃-140℃ | Ke kūpaʻa wela haʻahaʻa, mahana hana PS -30 ℃ -90 ℃ | Haʻahaʻa ka mahana hana EPS pale wela ≤85 ℃ |

He kūpaʻa ka pahu meaʻai microwave PP i nā mahana kiʻekiʻe o 130°C. ʻO kēia wale nō ka pahu plastik i hiki ke waiho ʻia i loko o ka umu microwave a hiki ke hoʻohana hou ʻia ma hope o ka hoʻomaʻemaʻe pono ʻana. He mea nui e hoʻomaopopo i kekahi mau pahu ʻaina microwave, ua hana ʻia ke kino o ka pahu me ka No. 05 PP, akā ua hana ʻia ke poʻi me ka No. 06 PS (polystyrene), he maikaʻi ka mālamalama o ka PS, akā ʻaʻole kūpaʻa i nā mahana kiʻekiʻe, I mea e palekana ai, e wehe i ke poʻi o ka pahu ma mua o ke kau ʻana i loko o ka microwave.
He mea hana ka PS no ka hana ʻana i nā kīʻaha o nā pahu noodles koke a me nā pahu meaʻai wikiwiki e hoʻohua ana. 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 ka wela nui. A ʻaʻole hiki ke hoʻohana ʻia e loaʻa nā waikawa ikaika (e like me ka wai ʻalani), nā mea alkaline ikaika, no ka mea e hoʻopau ia i ka polystyrene ʻaʻole maikaʻi no ke kino o ke kanaka. No laila, pono ʻoe e hoʻāʻo e pale i ka hoʻohana ʻana i nā pahu meaʻai wikiwiki e hoʻopaʻa i ka meaʻai wela.
Hana ʻia ka ipu meaʻai EPS me ka Polypropylene me ka mea puhi, a ʻaʻole ia i kaulana hou ma muli o ka BPA, kahi mea e hōʻino ai i ke olakino kanaka. I kēia manawa, he hana maikaʻi ʻole kona ma ke kūpaʻa kino a me ke kemika, paʻakikī ke hoʻohaumia, a he hopena maikaʻi ʻole i ke kaiapuni.
