Latest Patents
Wilfried Sturm holds a patent for a "Method for the production of foamed polystyrene films." This invention relates to a method of producing a multi-layer, preferably two-layer, sandwich of a foamed polystyrene film with a co-extruded unfoamed film. The method is particularly useful for further working into labels or shaped bodies utilizing the shrinkability of the films. The process involves extruding a polystyrene resin composition, along with nitrogen as an expansion agent and a pore-former, out of the nozzle of an extruder. The extruded composition is then expanded prior to cooling to below the softening point. The invention aims to produce foamed polystyrene films that are economical in material usage, resistant to breakdown, insensitive to aging, and readily printable. The method specifies the use of nitrogen in a controlled ratio, combined with a powdered mixture of sodium bicarbonate and citric acid, to achieve the desired film characteristics.
