Abstract: An antistatic sheet material and package formed therefrom is provided. The laminated sheet material includes a first inner layer which is preferably a coextruded film having a polyolefin ply and second copolymer ply of ethylene-acrylic acid copolymer, ethylene vinyl acetate copolymer, or blends thereof, a second intermediate layer such as a polyester film having an electrically conductive material thereon, and an outer layer of an antistatic material. The laminate may be formed by hot roll lamination or an adhesive may be used between the first and second layers.

Abstract: A flexible sheet material and package formed therefrom is provided. The multilayer sheet material includes a first flexible heat sealable plastic material with antistatic properties on at least the one major surface thereof which first layer is laminated to a second flexible plastic material with an electrically conductive material on the one major surface thereof and antistatic properties on the other major surface thereof.

Abstract: Rubber-reinforced alkenyl aromatic resinous polymers are prepared by polymerizing an alkenyl aromatic monomer such as styrene containing a reinforcing rubber until phase inversion occurs and subsequently adding an additional solution containing a reinforcing polymer such as rubber and containing polymerization.
