  • Publication number: 20060121219
    Abstract: Disclosed are void-containing polyester shrink films which show excellent density retention upon exposures to high temperatures. The films have high shrinkage and retain their low density after processing under conditions of temperature and moisture used in typical recycling processes. The films are useful for sleeve label and other shrink film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations. Also disclosed is a process for void-containing polyester shrink films having high shrinkage and low density after exposure to elevated temperatures.

  • Patent number: 6262182
    Abstract: The invention enables solution modification of a polyolefin with an unsaturated anhydride, unsaturated acid, or unsaturated ester, with high efficiency without the formation of undesirable impurities resulting from the competing reaction of the solvent with the unsaturated anhydride, unsaturated acid, or unsaturated ester. The process entails combining a polyolefin; a solvent; an unsaturated anhydride, unsaturated acid or unsaturated ester and a free-radical initiator to form a reaction mixture. The solvent is selected from the group consisting of substituted aromatic solvents which do not contain benzylic hydrogens and mixtures thereof. This reaction mixture is reacted under suitable conditions to produce a modified polyolefin.

  • Patent number: 5947126
    Abstract: A bundle of cellulose acetate fibers is bonded together with a water-soluble fiber-to-fiber bonding agent. The water-soluble fiber-to-fiber bonding agent may include 60-99 wt. % of a water-soluble binder and 40-1 wt. % of a plasticizer. As to the specific components, the water-soluble fiber-to-fiber bonding agent may be a mixture of a water-soluble polymer and glycerol triacetate. The bonded fibers are wrapped in a paper having opposing ends secured together with a water-soluble plug wrap adhesive. A plurality of cuts are made to extend more than one half way through the bundle wrapped fibers. The plurality of cuts may extend more than one half way through the bundle without extending completely through the bundle and may extend from a plurality of different directions.
