Monga zakudya zina za acidic kapena zakumwa zimatha kutulutsa mankhwala m'mitsuko yake, ndikofunika kuti zisungidwe muzotengera zoyenera.

Mu COPAK, onsemakapu apulasitiki a chakudyaamapangidwa kuchokera ku PET ndi PLA.M'munda wapulasitiki, PET imalembedwa ndi Code 1. Simuyenera kukhala katswiri wa mapulasitiki kuti muwone ngati chinthucho ndi chakudya.Khodiyo imakhala ndi makona atatu a mivi yozungulira nambala pakati pa 1 ndi 7. Nthawi zambiri, nambala 1 mpaka 7 imasonyeza pulasitiki ya chakudya.

PET imasonyeza kukana kwabwino kwa kuvala, mphamvu zapamwamba ndi flexural modulus, ndi kukhazikika kwapamwamba kwambiri (ie, impact resistance) Polyethylene terephthalate,makapu apulasitiki a chakudyamabotolo a zakumwa zamtundu umodzi (monga zakumwa zoziziritsa kukhosi, zakumwa zamasewera, madzi, ndi zina) mabotolo okometsera (monga saladi kuvala, ketchup, mafuta, ndi zina zotero), mabotolo a mavitamini, mitsuko ya batala wa peanut.

Ndi chiyani?Polyethylene terephthalate (PETE kapena PET) ndi pulasitiki yopepuka yomwe imapangidwa kuti ikhale yolimba kapena yolimba yomwe imapangitsa kuti ikhale yosagwira, ndipo imathandizira kuteteza chakudya kapena zakumwa mkati mwazovala.

Kodi amagwiritsidwa ntchito bwanji?Fmakapu apulasitiki abwinoamagwiritsidwa ntchito kwambiri popaka zakudya za zakumwa zozizilitsa kukhosi, zakumwa zamasewera, madzi osagwiritsidwa ntchito kamodzi, ketchup, kuvala saladi, mavitamini, mabotolo amafuta a masamba ndi zotengera za peanut butter.
