| Ipu kai PP | Ipu kai PS | ipu kai EPS | |
| Kai matua | Polypropylene (PP) | Polyethylene (PS) | Polypropylene pahuka (Poropirine me te matū pupuhi) |
| Mahi wera | He ātete wera nui, ka taea te whakamahana i roto i te ngaruiti hei whakamahana i te PP, whakamahia te pāmahana: -30℃-140℃ | Ātete wera iti, pāmahana whakahaere PS -30℃-90℃ | Te ātete wera iti o te pāmahana whakahaere EPS ≤85℃ |
| Ngā āhuatanga ā-tinana | He kaha teitei, he pakeke teitei, he ngāwari teitei hoki | He iti te kaha o te pānga, he pakarukaru, he ngawari hoki te pakaru | He iti te pakari, he ngoikore te ātete |
| Te pumau matū | Te pumau matū teitei (haunga te waikawa hauota kukū me te waikawa whanariki kukū), he pānga paturopi teitei | Kāore e taea te uta i ngā rauemi waikawa kaha me ngā rauemi turanga kaha | He iti te pumau matū, ka tauhohe ngā matū ki ngā waikawa kaha, ki ngā kakano kaha, ki ngā kakara me ētahi atu matū |
| Pānga ki te taiao | Ka taea te whakateretere i te pirau mā te tāpiri i ngā rauemi pirau, he ngāwari hoki te hangarua | He uaua ki te whakaiti | He uaua ki te whakaiti |
He ātete te ipu kai ngaruiti PP ki ngā pāmahana teitei o te 130°C. Koinei anake te pouaka kirihou ka taea te whakanoho ki roto i te oumu ngaruiti, ā, ka taea te whakamahi anō i muri i te horoinga āta. He mea nui kia mōhio ko ētahi pouaka tina ngaruiti, ko te tinana o te pouaka he mea hanga ki te Nama 05 PP, engari ko te taupoki he mea hanga ki te Nama 06 PS (polystyrene), he mārama te PS, engari kāore e ātete ki ngā pāmahana teitei. Hei haumaru, tangohia te taupoki o te ipu i mua i te whakanoho ki roto i te ngaruiti.
He rauemi te PS e whakamahia ana hei hanga peihana mō ngā pouaka nūru inamata me ngā pouaka kai tere pahuka. He ātete ki te wera, he ātete hoki ki te makariri, engari kāore e taea te whakanoho ki roto i te oumu ngaruiti hei karo i te tukunga o ngā matū nā te pāmahana nui rawa. Ā, kāore e taea te whakamahi hei pupuri i ngā waikawa kaha (pērā i te wai karaka), ngā matū kawakore kaha, nā te mea ka pirau te polystyrene kāore e pai mō te tinana tangata. Nō reira, me karo koe i te whakamahi i ngā pouaka kai tere hei tākai kai wera.
He mea hanga te ipu kai EPS ki te Polypropylene me te matū pupuhi, ā, kāore i te rongonui i ēnei rā nā te mea he BPA tōna, ka kino ki te hauora o te tangata. I taua wā, he tino ngoikore tana mahi i runga i te pumau ā-tinana me te matū, he uaua ki te pirau, he kino te pānga ki te taiao.
