What is oxo- biodegradability？
The term ‘oxo-biodegradability’ is a hybridisation of two wprds；Oxidation and biodegradability。It defines clearly a two step process initiated in this case by the Reverte additive degrading（breaking up）the polymer chain in order to make it available for biodegradability withib the environment when a treated item has finished its useful life
The oxidation phase reduces the polymer molecular weight and introduces oxygen into rhe structure。This process transforms the plastic from long strands to much smaller lengths。By reducing the chain length of the polymer the material loses its physical strength，making it brittle and non plastic。The biodegradability aspect refers to the conversion of these lower molecular weight species by bacteria into biomass，CO2 and H2O。
The advantages of the oxo-biodegradable packing bags
◆Possess a dwell time，the bags wont degrade before use for 18-24 months if stored in shadow place
◆The degradation is caused by sunlight and will not be reacted simply by temperature
◆Wont change the physical nature of the material
◆Still can be with the feature of high transparency ，maintain the appearance of the bags
◆Not contain cobalt at all （some countries take cobalt as heavy metal）
◆ Much cheaper than PLA and corn strach bags
