Process for Improved Barrier PLA Film

Executive Summary Consumers, companies, and governments are increasingly favoring compostable materials over fossil-based alternatives, as waste from traditional materials has escalated significantly in recent decades. However, a key challenge with compostable materials is their inferior oxygen and moisture barrier properties compared to non-compostable...

Water Dispersible Poly(dimethylsiloxane) Coatings for PFAS Replacement

Executive Summary Polyethylene-, polyvinylidene chloride-, and per- and polyfluoroalkyl substances (PFAS) -coated paper is used in applications requiring barrier properties such as grease and water resistance. However, the use of these chemicals present environmental challenges and make the coated paper difficult to recycle or compost. Researchers...

Biodegradable Barrier Coating for Paper

Executive Summary Coated paper is used in a variety of packaging applications including fresh produce, cheeses, confectionary, frozen fish and fast food. To achieve sufficient barrier properties, the paper is often coated with petroleum based waxes or polyfluorinated substances (PFAS). However, these coatings are not environmentally attractive and...

Polylactide Lignin Blends

Executive Summary Increasingly, bio-sourced and biodegradable materials are being sought to replace petroleum or gas based polymers. Polylactic acid (PLA) is a well known biodegradable polymer that is used in a range of applications from biomedical devices to packaging materials. However, PLA by itself suffers from some deficiencies in mechanical properties....

Novel Chain Extenders for Recycling Polyesters

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

Repulpable Omniphobic Paper Packaging Solution

Executive SummaryTraditional grease- and water-resistant paper packaging solutions have significant environmental concerns. Water-resistant products using low-density polyethylene (LDPE) liners are not repulpable, increasing municipal waste footprint. Oil-resistance is often achieved using toxic per and polyfluoroalkyl substances, which have been associated...
