Estimating the term…
Thermoplastics film containing inorganic fillers, metal/plastics composite containing inorganic fillers and process for the production thereof. The present invention relates to thermoplastics films, which contain at least 0.1% by weight, preferably 0.5 to 6% by weight, based on the total weight of the mixture of plastics and filler, of one or more metal powders, selected from aluminum powder, magnesium powder, zinc powder and manganese powder. The invention further relates to metal/plastics composites containing these metal powders, and processes for the production of the thermoplastics films and the metal/plastics composites. The plastics films and the metal/plastics composites are used for producing packaging containers.
Metal/plastics composite containing inorganic fillers, characterized in that a thermoplastics film selected from the group consisting of polyolefins, polyamides, polyesters, polyvinyl chloride, polyvinylidene chloride, polyurethanes and polycarbonates and bonded to a metal sheet of a thickness from 0.04 to 1 mm contains between 0.1% to 6% by weight, based on the total weight of the mixture of thermoplastics and filler, of at least one metal powder, selected from the group consisting of aluminum powder, magnesium powder, zinc powder, manganese powder and mixtures thereof, where the average particle size of the metal powder is in the range of 5 to 20 .mu.m.
