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.
