We are interested in biodegradable materials that can be used in barrier layers, adhesives, and additives to provide a moisture barrier and mechanical properties required by the intended packaging applications. This could include biopolyesters that may also perform as stand-alone films. The ideal materials are biodegradable and/or compatible with existing recycling streams. We are seeking solutions that address the high cost and performance challenges of biopolyesters currently on the market. This may include alternatives to polyethylene such as PHA, seaweed-based materials, or cellulose films. We are looking for solutions that either reduce the high production cost of biopolyesters or address their current performance challenges. We are particularly interested in biodegradable materials for use in barrier layers, adhesives, and additives that can confer biopolyesters with the moisture barrier and mechanical properties needed for the intended packaging applications.

• Coating or co-polymerization
• Biodegradable additives (that accelerate biodegradability or composability)
• Multilayer biopolyester films
• Analogous novel materials (biobased plastics)
• Cross-linking of biopolymers

• Integrates into recycling or composting infrastructure, and poses no environmental hazard if entering waste streams
• Clear pathway to commercialization regarding mass production
• Benchmarked against traditional polyethylene packaging for moisture-barrier and mechanical performance required in intended application
• Properties that fit into a circular economic model for packaging materials (biodegradability and recyclability)

• Addresses the high cost of biopolyesters

• Manufactured within existing infrastructure, for example, paper milling, paper coating, and film extrusion processes

• Designed to go to landfill

• Oxo-degradable

• Requires scarce or unsustainable feedstocks
