Plastiki masterbatche ka bonoa e le li-polymersmasterbatch.Li-polymers li ka etsoa ka mefuta e mengata e fapaneng ea 'mers' e emelang likarolo tsa lik'hemik'hale.Likarolo tse ngata tsa lik'hemik'hale li tsoa ho oli kapa li-hydrocarbon tse ling.Li-hydrocarbon li joalo ka ha li hlaha, li entsoe ka hydrogen le carbon.Kahoo, lipolasetiki li entsoe ka (haholo-holo) hydrogen le carbon tse kopantsoeng hammoho ho etsa mers (joaloka ethylene kapa propylene) ebe li-mers tsena li hokahana ho etsa liketane le ha liketane tsena li le telele ho lekana ho fetoha 'poly' hangata ha bonyane. Li-mers tse 100 li hokahane hammoho, re fumana thepa ea polasetiki / polymeric.
