    Abstract: The present invention provides polylactic compositions effecting an excellent mold releasability upon processing and significantly improved elongation at break and impact strength without affecting the transparency. Also provided is a shrink film which decomposes under the natural environment and has excellent transparency, flexibility, shrinkability and mold releasability upon processing by applying the polylactic acid composition to a shrink film. There is provided a biodegradable polymer composition comprising 100 parts by weight of polylactic acid and 5 to 70 parts by weight of EVA. Further, a biodegradable polymer composition is provided comprising the polymer composition with one or more additives selected from the group consisting of 0.05 to 5 parts by weight of a lubricant, 1 to 50 parts by weight of plasticizer, 0.5 to 5 parts by weight of thermal stabilizer and 0.05 to 5 parts by weight of mold releasing agent. These biodegradable polymer compositions are applied to shrink films.

    Abstract: This invention discloses a bioplastic composition comprising biomass as a component comprising a plastic compound resin comprising polybutylene succinate (PBS), polylactic acid (PLA), and additives selected from biomass from the coffee roasting processes, i.e. silver skin of coffee (SSC); and/or at least one fluoropolymer or fluoropolymer derivative as a friction reducing agent. This invention also relates to a process of pretreating the silver skin coffee for using as an additive for bioplastic resin to produce various products or using as a natural color masterbatch together with other plastics via extrusion, injection molding, compression and thermoforming processes in the industrial level.
