| Ikintu cy'ingenzi gikoreshwa
| Polypropylene (PP) | Polyethylene (PS) | Polypropylene ifite ifuro (Polpropylene ifite igikoresho cyo gushyushya) |
| Imikorere y'ubushyuhe | Ubushyuhe bwinshi bushobora gushyuha muri mikoroonde, ubushyuhe bukoreshwa: -30℃ -140℃ | Ubushyuhe buke budashobora guhagarara, ubushyuhe bwo gukora bwa PS -30℃ -90℃ | Ubushyuhe bwo gukora bwa EPS bufite ubushobozi bwo kwirinda ubushyuhe buke ≤85℃ |
| Imiterere ifatika | Ingufu nyinshi, ubukana bwinshi n'ubudahangarwa bwinshi | Ingufu nke, zoroshye kandi zirashobora kuvunika | Ubukomere buke, kutabasha kwinjira neza |
| Gukomera kw'ibinyabutabire
| Ubudahangarwa bwinshi bw'imiti (usibye aside nitrike ikomeye na aside sulfurike ikomeye), ingaruka nziza zo kurwanya udukoko | Ntibishobora gushyiramo aside ikomeye n'ibikoresho by'ibanze bikomeye
| Idahinduka cyane mu mikorere ya shimi, ihura n'aside ikomeye, ishingiro rikomeye, uburyohe n'ibindi bintu |
| Ingaruka ku bidukikije | Kubora bishobora kwihutishwa no kongeramo ibikoresho bishobora kwangirika, byoroshye kongera gukoreshwa | Bigoye kwangiza | Bigoye kwangiza |
Igikoresho cyo kurya cya PP gikoreshwa muri mikoroonde kirwanya ubushyuhe bwinshi bwa dogere selisiyusi 130. Aka ni ko gasanduku k'ipulasitiki konyine gashobora gushyirwa mu itanura rya mikoroonde kandi gashobora kongera gukoreshwa nyuma yo gusukurwa neza. Ni ngombwa kumenya ko udusanduku twa microwave two kurya, umubiri w'agasanduku ukozwe muri No 05 PP, ariko umupfundikizo ukozwe muri No 06 PS (polystyrene), PS ifite ubushobozi bwo kubonerana neza, ariko ntirwanya ubushyuhe bwinshi. Kugira ngo ube ufite umutekano, kura umupfundikizo w'agasanduku mbere yo kuwushyira muri mikoroonde.
PS ni ibikoresho bikoreshwa mu gukora amabakure y’udusanduku twa noodles dukonjesha vuba hamwe n’udusanduku tw’ibiryo byihuse dufuro. Ntibishobora gushyuha kandi ntibikonjesha, ariko ntibishobora gushyirwa mu itanura rya mikoroonde kugira ngo hirindwe ko hasohoka imiti ikomoka ku bushyuhe bwinshi. Kandi ntibishobora gukoreshwa mu gushyiramo aside ikomeye (nk'umutobe w'icunga), ibintu bikomeye bya alkaline, kuko byangiza polystyrene atari byiza ku mubiri w'umuntu. Kubwibyo, ugomba kugerageza kwirinda gukoresha udusanduku tw’ibiryo byihuse mu gupakira ibiryo bishyushye.
Agasanduku k'ibiribwa ka EPS gakozwe muri Polypropylene gafite igikoresho cyo gushyushya, kandi ntabwo kagikunzwe cyane kubera BPA, byaba byangiza ubuzima bw'umuntu. Hagati aho, gafite imikorere mibi cyane ku bushyuhe n'ubudahangarwa bw'ibinyabutabire, karagoye kwangiza, kandi kagira ingaruka mbi ku bidukikije.
