发明名称 POLYMER FILMS WITH TREATED FILLERS AND PRODUCTS AND METHODS OF USING SAME
摘要 The present invention provides for a polymer composite film with a treated filler and methods for making the same. The polymer composite film includes a polymer capable of being formed into a polymeric film and a treated filler which is dispersed throughout the polymer forming the composite film. The filler is treated by techniques which exfoliate, delaminate or intercalate the filler particles into individual micro and/or nano size particulates and platelets. Ideally, the treated filler has a medium particle size ranging from about 0.1 nm-10 mm. The treated filler enhances the rigidity, barrier properties, heat deflection temperature, clarity, nucleation characteristics and fire retardant characteristics of the film. The products fabricated from the polymer composite film include sleeves, protective packaging, films, bags, liners, house-wraps, overwrap films, bubble cushion, packaging for food products, boil-in bags, heat shrinkable films, heat shrinkable bags, pouches, and thermoformed packages. The present invention also provides for methods of fabricating the polymer composite film.
