Abstract: A method of labeling rubber component bags is provided. The method includes the steps of: (1) forming a label having a first side with an adhesive and a second side; (2) applying a first identifying marker to the second side of the label; (3) adhering the label to a bag adapted to hold a component to be used in making rubber; (4) inserting the bag and the label into a rubber mixing machine used to form the rubber mixture; and, (5) mixing the label into rubber mixture. Labels formed according to the method of this invention melt and disperse throughout the rubber mixture without negatively affecting the properties of the rubber mixture.

Abstract: The present invention is a molding compound comprising an unsaturated polyester resin, a filler, a reinforcement material, a crosslinking monomer, a catalyst, and a mold release agent. The compound also may include a thickener and a low profile thermoplastic additive. The mold release agent is a liquid at room temperature and is selected from the group consisting of tertiary alkyl primary amine carboxylates. The present invention further includes a method of manufacturing a molded plastic component using said molding compound.

Abstract: Ethylene vinyl acetate copolymer films having about 25%-33% by weight vinyl acetate and melting points of about 160.degree.-170.degree. F. are provided for packaging, lining or wrapping purposes. Low melt bags for rubber compounds and additives are made from the films.
