Abstract
Bio-based and biodegradable polymer of the type used in the manufacture of films and injected or molded products, for example, for applications of containers, bags, healthcare products and films for agriculture or other applications in which the biodegrading characteristic is of interest, has a biodegradable polymer, thermoplastic starch in the co-continuous or continuous phase and at least one polymer that comes from a stable dispersion of the polymer in water or latex. This increases the thermoplastic starch content and thus decreases the biodegradable polymer and obtains films of a greater width by blow extrusion, with similar tensile properties. This provides the added advantage of a lower cost in raw materials, less impact on the environment and greater production.
