| Isithako esiphambili | I-Polypropylene (PP) | I-Polyethylene (PS) | I-polypropylene enegwebu (I-Polypropylene ene-agent yokuvuthela) |
| Ukusebenza kobushushu | Ukumelana nobushushu obuphezulu, ingafakwa kwi-microwave ukuze ifudumale i-PP, sebenzisa ubushushu: -30℃ -140℃ | Ukumelana nobushushu obuphantsi, ubushushu bokusebenza be-PS -30℃ -90℃ | Ubushushu obuphantsi bokumelana nobushushu obuphantsi Ubushushu bokusebenza be-EPS ≤85℃ |
| Iimpawu zomzimba | Amandla aphezulu, ubulukhuni obuphezulu kunye nokuqina okuphezulu | Amandla aphantsi okubetha, abuthathaka kwaye ayaphuka | Ubunzima obuphantsi, ukungangeni kakuhle |
| Uzinzo lweekhemikhali | Uzinzo oluphezulu lweekhemikhali (ngaphandle kwe-nitric acid egxininisiweyo kunye ne-sulfuric acid egxilileyo), isiphumo esiphezulu se-antiseptic | Ayikwazi ukulayisha izinto ze-asidi enamandla kunye neziseko eziqinileyo | Uzinzo oluphantsi lweekhemikhali, isabela ngokweekhemikhali kunye nee-asidi ezinamandla, iziseko ezinamandla, iincasa kunye nezinye izinto |
| Impembelelo yokusingqongileyo | Ukubola kungakhawuleziswa ngokongeza izinto ezibolayo, kulula ukuzisebenzisa kwakhona | Kunzima ukuthoba umgangatho | Kunzima ukuthoba umgangatho |
Isitya sokutya se-microwave se-PP simelana namaqondo obushushu aphezulu angama-130°C. Le yibhokisi yeplastiki kuphela enokufakwa kwi-oven ye-microwave kwaye inokusetyenziswa kwakhona emva kokucocwa ngononophelo. Kubalulekile ukuqaphela ukuba ezinye iibhokisi zesidlo sasemini ze-microwave, umzimba webhokisi wenziwe ngeNombolo 05 PP, kodwa isiciko senziwe ngeNombolo 06 PS (polystyrene), i-PS inokukhanya okuhle, kodwa ayimelani namaqondo obushushu aphezulu. Ukuze ukhuseleke, susa isiciko sesitya ngaphambi kokuba usifake kwi-microwave.
I-PS yinto esetyenziselwa ukwenza izitya zeebhokisi zeenoodles ezikhawulezayo kunye neebhokisi zokutya okukhawulezayo ezinegwebu. Ayinakumelana nobushushu kwaye ayibanda, kodwa ayinakubekwa kwi-oven ye-microwave ukuthintela ukukhutshwa kweekhemikhali ngenxa yobushushu obugqithisileyo. Kwaye ayinakusetyenziswa ukuqulatha ii-asidi ezinamandla (ezifana nejusi yeorenji), izinto ezinamandla ze-alkaline, kuba iya kubolisa i-polystyrene engalunganga emzimbeni womntu. Ke ngoko, kufuneka uzame ukuphepha ukusebenzisa iibhokisi zokutya okukhawulezayo ukupakisha ukutya okushushu.
Isikhongozeli sokutya se-EPS senziwe ngePolypropylene ene-blowing agent, kwaye ayisathandwa ngenxa ye-BPA, enokuba yingozi kwimpilo yabantu. Okwangoku, asisebenzi kakuhle kakhulu ekuzinzeni kobushushu kunye neekhemikhali, kunzima ukuwohloka, kwaye sinefuthe elibi kwindalo esingqongileyo.
