The main property is completely biodegradable within two years after the product is discarded.
The high molecular weight of commercial grades of polymers render them too hydrophobic and therefore very resistant to direct microbial attack.But for our biodegradable film,the oxo-degradation of the polymer chains is initially catalysed in the results of the promoting of the growth of microbial colonies,finaly the chains are short enough for micronbial digetion following of the initial oxo-breakdown. The rate of biodegradation is lying on vagaries of natural conditoins ,such as sunlight ,soil temperature ,ect.
It possess all the properties of common pof shrink film in addition to the biodgradation. It is absolutely an idea enviromental-friendly product in this morden society.
