Biobased Films with Improved Oxygen Barrier

Executive Summary Biobased materials such as polybutylene adipate terephthalate (PBAT), polyglycolic acid (PGA) and polybutylene succinate (PBS) are attractive materials for packaging films due to their positive sustainability aspects including biodegradability. However, their oxygen barrier properties limit the use of these materials to certain applications....

Process for Chemical Recycling of Multilayer & Metallized Plastic Packaging Films

Executive Summary In order to combat the growth of global plastic waste, pyrolysis processes have been developed to turn this waste material into gases, oils and waxes. However, these processes usually require high operating temperatures, expensive catalysts and restrictions on the type of plastics they can handle. Researchers at Michigan State University...

Sustainable Chain Extenders for Recycling Polyesters

Executive Summary Polyesters comprise a significant portion of plastics entering landfills. One issue that limits their recycling is degradation during melt processing which lowers their molecular weight and melt viscosity. Reactive chain extenders are often used in this case to build back the molecular weight of the polyester during reprocessing....
