Chikho cha Pulasitiki cha Chakudya Chapamwamba

Pulasitiki yapamwamba pa chakudya imatchulidwa bwino ngati pulasitiki yotetezeka pa chakudya. Mawuwa amatanthauza pulasitiki iliyonse yoyenera kukhudzana ndi chakudya kapena zakumwa zomwe zingagwiritsidwe ntchito.Chikho cha pulasitiki chapamwamba cha chakudyaZimateteza zakudya kuti zisawonongeke, zimateteza chakudya komanso zimapangitsa kuti zakudya zikhale zatsopano. Popeza zakudya zina zokhala ndi asidi kapena zakumwa zimatha kutulutsa mankhwala m'zidebe zawo, ndikofunikira kuti zisungidwe m'zidebe zoyenera.

Mu COPAK, onsemakapu apulasitiki apamwamba chakudyaAmapangidwa kuchokera ku PET ndi PLA. Mu pulasitiki, PET imalembedwa ndi code ndi Code 1. Simuyenera kukhala katswiri wa pulasitiki kuti mudziwe ngati chinthucho chili ndi kalasi ya chakudya. Code imakhala ndi mivi itatu yozungulira nambala pakati pa 1 ndi 7. Kawirikawiri, manambala kuyambira 1 mpaka 7 amasonyeza pulasitiki ya kalasi ya chakudya.

PET imasonyeza kukana kwabwino kwambiri kwa kuvala, mphamvu yayikulu komanso kusinthasintha kwa flexural modulus, komanso kukhazikika kwabwino kwambiri (monga, kukana kukhudzidwa). Polyethylene terephthalate,makapu apulasitiki apamwamba chakudyamabotolo a zakumwa zoperekedwa kamodzi kokha (monga zakumwa zoziziritsa kukhosi, zakumwa zamasewera, madzi, ndi zina zotero) mabotolo a zokometsera (monga saladi, ketchup, mafuta, ndi zina zotero), mabotolo a mavitamini, mabotolo a peanut butter

Kodi ndi chiyani? Polyethylene terephthalate (PETE kapena PET) ndi pulasitiki yopepuka yomwe imapangidwa kuti ikhale yolimba pang'ono kapena yolimba yomwe imapangitsa kuti isagwe kwambiri, komanso imathandiza kuteteza chakudya kapena zakumwa mkati mwa phukusi.

Kodi imagwiritsidwa ntchito bwanji? Fmakapu apulasitiki a kalasi yabwinoamagwiritsidwa ntchito kwambiri m'maphukusi azakudya a zakumwa zoziziritsa kukhosi, zakumwa zamasewera, madzi operekedwa kamodzi kokha, ketchup, saladi dressing, mavitamini, mabotolo a mafuta a masamba ndi zotengera za peanut butter.
