  • Publication number: 20090297820
    Abstract: A film, for use in a label and a related method, including a print skin layer, a base layer, and an adhesive skin layer having at least one heat-activated thermoplastic polymer. The film is stretched biaxially in both a machine direction and a transverse direction. The stretch ratio in a first direction is greater than 2:1 to 10:1, the stretch ratio in a second direction ranges in value from 1.02:1 to 1.8:1, the film has an ASTM D1204 shrinkage at 100° C. of at least 0.5% in both the machine and transverse directions, and the film has an ASTM D882 2% secant modulus of at least 679,134 kPa (98,500 psi) in the first direction.

  • Patent number: 6808822
    Abstract: The present invention relates to a halogen-free, multilayered, uniaxially oriented heat shrink film comprising (A) a core layer comprising a blend of polyolefins; (B) a first skin layer on the upper surface of the core layer, and (C) a second skin layer on the lower surface of the core layer, wherein the first and second skin layers independently comprise a polyolefin blend and wherein the shrinkage of the film is at least about 40% in the machine direction at 270° F. The present invention further relates to a label having an adhesive applied to at least a portion of at least one of the skin layers of the multilayered heat shrink film. The heat shrink labels of the present invention are used to encapsulate articles.
