| Chidebe cha chakudya cha PP | Chidebe cha chakudya cha PS | Chidebe cha chakudya cha EPS | |
| Chosakaniza chachikulu | Polypropylene (PP) | Polyethylene (PS) | Polypropylene yokhala ndi thovu (Polypropylene yokhala ndi chopangira kupopera) |
| Magwiridwe antchito a kutentha | Kukana kutentha kwambiri, kumatha kutenthedwa mu microwave kuti kutenthetse PP, kutentha kogwiritsa ntchito: -30℃ -140℃ | Kukana kutentha pang'ono, kutentha kwa PS -30℃ -90℃ | Kutentha kochepa kwa EPS kutentha kogwira ntchito ≤85℃ |
| Katundu wakuthupi | Mphamvu yayikulu, kuuma kwakukulu komanso kusinthasintha kwakukulu | Mphamvu yochepa yogunda, yosalimba komanso yosweka | Kulimba kochepa, kusagwira bwino ntchito |
| Kukhazikika kwa mankhwala | Kukhazikika kwa mankhwala ambiri (kupatula asidi ya nitric yokhazikika ndi asidi ya sulfuric yokhazikika), mphamvu yayikulu yopha tizilombo toyambitsa matenda | Sitingathe kuyika zinthu zolimba za asidi ndi maziko olimba | Kukhazikika kochepa kwa mankhwala, mankhwala amakumana ndi ma asidi amphamvu, maziko amphamvu, zokometsera ndi zinthu zina. |
| Zotsatira za chilengedwe | Kuwola kumatha kufulumizitsidwa powonjezera zinthu zomwe zimawonongeka, zosavuta kubwezeretsanso | Zovuta kuzichepetsa | Zovuta kuzichepetsa |
Chidebe cha chakudya cha microwave cha PP chimapirira kutentha kwambiri kwa 130°C. Ili ndi bokosi lokhalo la pulasitiki lomwe lingayikidwe mu uvuni wa microwave ndipo lingagwiritsidwenso ntchito mutatsuka mosamala. Ndikofunikira kudziwa kuti mabokosi ena a chakudya chamasana a microwave, thupi la bokosilo limapangidwa ndi Nambala 05 PP, koma chivindikirocho chimapangidwa ndi Nambala 06 PS (polystyrene), PS imakhala yowonekera bwino, koma siimalimbana ndi kutentha kwambiri. Kuti mukhale otetezeka, chotsani chivindikiro cha chidebecho musanachiike mu microwave.
PS ndi chinthu chomwe chimagwiritsidwa ntchito popanga mbale za mabokosi a noodles ofulumira komanso mabokosi a chakudya chofulumira. Sichitentha komanso sichizizira, koma sichingayikidwe mu uvuni wa microwave kuti chisatulutse mankhwala chifukwa cha kutentha kwambiri. Ndipo sichingagwiritsidwe ntchito kukhala ndi ma acid amphamvu (monga madzi a lalanje), zinthu zamphamvu za alkaline, chifukwa chimawononga polystyrene yomwe si yabwino kwa thupi la munthu. Chifukwa chake, muyenera kuyesetsa kupewa kugwiritsa ntchito mabokosi a chakudya chofulumira ponyamula chakudya chotentha.
Chidebe cha chakudya cha EPS chimapangidwa ndi Polypropylene yokhala ndi chofufutira, ndipo sichikutchukanso chifukwa cha BPA, zomwe zingakhale zoopsa pa thanzi la anthu. Pakadali pano sichigwira ntchito bwino pa kutentha kwa thupi ndi mankhwala, chimakhala chovuta kuchiwononga, komanso chimakhudza kwambiri chilengedwe.
