FORMULATION FOR CARD STOCK APPLICATIONS - METHODS FOR DISPLACING PVC BY USING RECYCLED PETG, COPOLYESTERS, AND POLYESTERS (INCLUDING "OCEAN BOUND") OR OTHER SUSTAINABLE POLYESTER MATERIALS ("BIO-BASED", "RENEWABLY SOURCED", OR "COMPOSTABLE")
Disclosed are methods for enhancing recycled polymer materials for use in manufacturing film/sheet products involves obtaining a polymer starting material for recycling, heating it through melt compounding and/or extrusion processes, and incorporating modifiers such as ethylene/acrylate copolymer, ethylene/acrylate/glycidyl methacrylate terpolymer, and ethylene/glycidyl methacrylate copolymer before extrusion. The resulting modified recycled material can substitute for PVC or other virgin polymers in producing extruded film/sheet products or molded goods. This method enables the creation of mono-layer or multi-layer film/sheet products with improved properties, contributing to sustainable and environmentally friendly manufacturing practices.
