Indebe yePlastiki yeBanga lokutya

Iplastiki yodidi lokutya ichazwa ngcono njengeplastiki ekhuselekileyo ekutyeni. Eli gama libhekisa kuyo nayiphi na iplastiki efanelekileyo ukuba idibane nokutya okanye iimveliso zeziselo ezisetyenziswayo.Ikomityi yeplastiki yeklasi yokutyainokukhusela ukutya ekonakalisweni, ibonelela ngokhuseleko lokutya kwaye yandise ubutsha bokutya. Njengoko ezinye ukutya ezine-asidi okanye ulwelo zinokukhupha iikhemikhali kwizikhongozeli zazo, kubalulekile ukuba zigcinwe kwizikhongozeli ezifanelekileyo.

Kwi-COPAK, zonkeiikomityi zeplastiki zezinga lokutyaZenziwe ngePET kunye nePLA. Kwintsimi yeplastiki, iPET iphawulwa ngekhowudi yiKhowudi 1. Akunyanzelekanga ukuba ube yingcali yeplastiki ukuze ubone ukuba into ethile ikumgangatho wokutya na. Le khowudi inonxantathu weentolo ezijikeleze inani eliphakathi kwe-1 kunye ne-7. Ngokubanzi, amanani ukusuka ku-1 ukuya ku-7 abonisa iplastiki yomgangatho wokutya.

I-PET ibonisa ukumelana nokuguguleka okugqwesileyo, amandla aphezulu kunye ne-flexural modulus, kunye nozinzo oluphezulu (oko kukuthi, ukumelana nempembelelo). I-Polyethylene terephthalate,iikomityi zeplastiki zezinga lokutyaiibhotile zeziselo ezisetyenziswa kanye kuphela (umz., iziselo ezibandayo, iziselo zemidlalo, amanzi, njl. njl.) iibhotile zezinongo (umz., isaladi yokugquma, iketchup, ioyile, njl.njl.), iibhotile zeevithamini, iijagi zebhotolo yamandongomane

Yintoni? I-Polyethylene terephthalate (PETE okanye PET) yiplastiki ekhaphukhaphu eyenziwe ukuba iqine okanye iqine nto leyo eyenza ukuba ikwazi ukumelana nokutsha, kwaye incede ekukhuseleni ukutya okanye ulwelo ngaphakathi kwiphakheji.

Isetyenziswa njani? Fiikomityi zeplastiki zezinga eliphezuluIsetyenziswa kakhulu ekupakisheni ukutya kweziselo ezibandayo, iziselo zemidlalo, amanzi asetyenziswa kanye, i-ketchup, isaladi yokugquma, iivithamini, iibhotile zeoyile yemifuno kunye nezikhongozeli zebhotolo yamandongomane.
