The composition based on polymers for the manufacture of products made of plastics degradable in the environment and plastic materials obtained

摘要

The present invention relates to products made of plastics material and of the compositions for the manufacture of such as plastics, obtained from natural sources degradable in the environment. For this purpose, the invention relates to a composition based on polymers for the manufacture of a plastic material of a degradable into the environment, comprising a component of algae and at least one plasticizing compound, characterized in that said component of the algae is comprised between 20 and 40% by weight, of an extract of polysaccharides refined of macro - algae, or between 20 to 65% by weight, of an extract of polysaccharides semi - refined of macro - algae, in which the macro - algae non-food are green algae, in particular of the genus ulva or brown algae, in particular of the genus sargassum.
