Abstract: A mono or multi-layer biaxially oriented polyester film is described. Also described, is a process for producing the mono or multi-layer biaxially oriented polyester film. Uses of a surface-treated filler material product as a voiding agent in the mono or multi-layer biaxially oriented polyester film, an article that includes the mono or multi-layer biaxially oriented polyester film as well as the use of the mono or multi-layer biaxially oriented polyester film in packaging products are also described. The packaging products can include: paper and glass coverings, insulating materials, solar, marine and aviation applications, science, electronic and acoustic applications, wires, cables, radio frequency identifications, flexible circuits, graphic arts, filter products, cosmetic products, household products, imaging and recording media, or industrial products.

Abstract: The present invention relates to a breathable film having a basis weight from 1 to 15 g/m2 comprising at least one thermoplastic polymer and a surface-treated filler material comprising calcium carbonate. The surface-treated filler material has a specific particle size distribution and a specific surface-treatment layer. The present invention further relates to a process for producing the breathable film, the use of a surface-treated filler material comprising calcium carbonate as a filler in a breathable film, an article comprising the breathable film and uses of the breathable film.

Abstract: The use of at least one mono-substituted succinic anhydride is described before or during compounding of a polymer composition including at least one polymer as polymer component and at least one calcium carbonate-based material as filler. The use of the at least one mono-substituted succinic anhyride can reduce the polymer decomposition during processing and/or can decrease the melt flow rate of such a compounded polymer composition by at least 10%. The use can also increase the viscosity of such a compounded polymer composition by at least 10%, in comparison to the same polymer composition that has been treated the same way in the absence of any mono-substituted succinic anhydride, wherein the polymer composition does not include polylactic acid.
