What is the difference between compostable and oxo-biodegradable?
A. Compostable products must degrade in the time frame prescribed by ASTM D 6400 test. The most popular compostable resin is polyactic acid (PLA).We manufacture oxo-biodegradable polyethylene recognized by ASTM D6954 – 04. Our products meet 3 of 4 requirements D 6400. Conversion of polymers into smaller elements does not occur rapidly enough to meet the ASTM D 6400 standard. Q. Can you make a film or bag that is a blend of PLA and polyethylene? A. No, the resins are too dissimilar. Q. How do you know it works? A. Every application is put through an accelerated aging test replete with a control which has no biodegrading agent. A thorough analysis is conducted afterwards. In addition to measuring the changes in physical properties, we measure the change at a molecular level through infrared analysis. Q. Exactly what will I look at after film degrades to molecules? A. PE containing TDPA will first undergo degradation by reacting with oxygen to form molecular fragments that are water-wetta
