Abstract

PURPOSE:To make the heat resistance of a heat-sealing layer larger and enhance the heat shrink by a method wherein heat-shrinkable packaging material is formed by extrudingly laminating the heat-sealing layer consisting of straight- chain low-density polyethylene resin onto a synthetic resin film. CONSTITUTION:A heat-shrinkable packaging material is formed by extrudingly laminating a heat-sealing layer consisting of straight-chain low-density polyethylene resin onto a synthetic resin film having heat shrink characteristics. As the synthetic resin film having heat shrink characteristics, heat-shrinkable nylon film, heat-shrinkable polyester film, heat-shrinkable polyvinylidene chloride-based film or the like is used. The thickness of the straight-chain low-density polyethylene resin layer to be formed is normally about 25-40mum. However, the application of adhesion improvement treatment such as the application of anchoring agent is preferable before the formation of the heat-sealing layer on the surface of the synthetic resin film having heat shrink characteristics.
