  • Polyolefin-based laminated film
    Patent number: 5698317
    Abstract: A polyolefin-based laminate film including at least 4 layers which includes a polyolefin-based resin layer; a polyolefin-based mixed resin layer formed on one surface of the polyolefin-based resin layer of which surface is treated by a discharge treatment, the polyolefin-based mixed resin layer containing at least one of petroleum resins and terpene resins in an amount of 5-30% by weight; a vapor deposited metal layer formed on the discharging-treated surface of the polyolefin-based mixed resin layer; and a heat seal layer formed on the surface of the polyolefin-based resin film opposite the surface on which the polyolefin-based mixed resin layer is formed. The laminate film has excellent moisture-proof and gas-barrier properties, and the rejection rate due to blocking in the production process is low.
