Abstract: A process for manufacturing extrudable/melt spinnable concentrate pellets which contain phase change materials (PCMs), whether the PCMs are micro-encapsulated absorbed into carrier polymers, or non-micro-encapsulated within the concentrate pellets. The polymer matrix within the concentrate pellets can be any thermoplastic polymer or combination of thermoplastic polymers, and the concentrate pellets can then be blended into similar thermoplastic polymers to form mono-filament melt spun fibers, extruded films, injection molded products, etc., or the concentrate pellets can be blended with other thermoplastic polymers to form bi-component or multi-component melt spun fibers, extruded films, injection molded products, etc.

Abstract: A compostable multilayer structure in the form of a film, sheet, laminate, and the like, which comprises a core layer having a first surface and a second surface, a first blocking reducing layer covering the first surface of the core layer, and a second blocking reducing layer covering the second surface of the core layer. The core layer contains a lactic acid residue-containing polymer and has a glass transition temperature (T.sub.g) below about 20.degree. C. The first and second blocking reducing layers include a polymer composition of a hydrolyzable polymer and have a T.sub.g above about 50.degree. C. The multilayer structure can be used for preparing bags and wrappers.
