FILM FORMATION WITH CALCITE

摘要

A composition which, when mixed with a polymer composition, allows for the formation of a continuous and cohesive film. The film is characterized in that it provides water, grease and oil resistance, provides a water vapour barrier and can used as wax replacement treatment and a top coat for flexible packaging, but also on other substrates. This film is formed at a very fast set speed without the need of thermal energy. The composition contains i) calcite alone or in combination with a salt of one or more of myristic, palmitic and stearic acid; and also ii) a C9-C18 fatty acid complex of a metal ion, the metal ion having an oxidation state of at least 3. The composition is incorporated in material such as cellulose based material or plastic based material.
