Now we have the 100% biodegradable and compostable masterbatch or resins, it´s resins made of PBAT, PLA and Corn Starch. After the process of biodegradation the bags will turn into CO2 and water. LDPE or LLDPE bags with additives are totally different. The bags with degradable additives are degradable but not biodegradable. So called OXO degradable, after a certain time the bags will break into tiny pieces, but the pieces are still LDPE or LLDPE. It´s even worse for the environment,because the tiny pieces are impossible to collect or recycle.
