Brief Project Summary:
Pressure sensitive adhesives (PSAs) are widely used for packaging tapes, labels, stamps, protective films, bandages, and many other applications. Existing PSAs are mainly derived from non-renewable petrochemical-based polymers that are expensive, not biodegradable, and not environmentally friendly. Most of existing PSA-based tapes and labels are produced through the following long and energy-consuming process: coating a water emulsion or solution of PSAs in petroleum solvent onto film or paper, followed by drying in a heated oven for removal of water or a solvent. We have invented soybean oil-based PSAs that do not contain any water or solvent. Laboratory results reveal that our PSAs have superior adhesion properties. The PSAs are cost-competitive to existing petrochemical-based PSAs. We are facing great difficulty in marketing the PSAs because we don’t have scientific data that demonstrate that the PSAs are truly biodegradable. It is urgent to obtain the data now. In this project, we will evaluate the biodegradability of our PSAs in accordance with ASTM D5511-18 (Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under High-Solids Anaerobic-Di
