Fast Reheated CSD PET Resin
Khoom Taw Qhia
Fast Reheated CSD PET Resin, uas tsim nyog rau kev siv ob kauj ruam tshuab ua cov ntim ntim rau cov dej haus carbonated thiab tau siv dav los ntawm cov chaw tsim khoom hauv South thiab North America, Europe thiab Coca-cola Tuam Tshoj.
Thaum lub sij hawm tsim cov txheej txheem, cov chips zoo li no muaj cov yam ntxwv tseem ceeb ntawm kev nqus cua sov sai, txo lub zog noj, ua kom lub tshuab nrawm thiab tso zis, thiab txhim kho kev ua haujlwm.Vim yog daim ntawv qhia cov txheej txheem tshwj xeeb thiab cov cuab yeej siv ntau lawm, cov khoom tshiab no muaj cov khoom zoo heev thiab tawm hauv cov qauv kev ua haujlwm tseem ceeb raws li cov qib Carbonated lub raj mis qib chips tsis hloov.Cov xim rau cov chips no yog me ntsis npub, tab sis cov khoom kawg yog qhov zoo heev hauv pob tshab.
