摘要:
A biaxially oriented laminate film including a core layer including a blend of crystalline polylactic acid polymer and an inorganic antiblock particle which is biaxially oriented at low transverse direction orientation temperatures to impart a degree of cavitation around the particles such that a matte or opaque appearance is obtained. The laminate film may further have additional layers such as a heat sealable layer disposed on one side of the core layer including an amorphous polylactic acid resin and/or a polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.
摘要:
A monoaxially oriented films and methods of making films including a heat sealable layer including propylene homo-polymer or copolymer and 3-15 wt % of at least one elastomer. The oriented films have a refractive index that satisfies the condition 5≦delta n=|n (MD)−n (TD)|×1000≦25, in which n (MD) is a refractive index of the film in a machine direction, and n (TD) is a refractive index of the film in a transverse direction. The films are suitable for pouch applications requiring an “easy-tear” linear tear feature and excellent hermetic seal properties, particularly for retort pouches
摘要:
A monoaxially oriented film including a propylene-based random copolymer and at least about 3 wt % of a low density polyethylene which is oriented at least about 2.5 times in one direction and exhibits excellent linear directional tear properties parallel to the orientation direction and excellent heat seal performance in terms of high heat seal strengths and low seal initiation temperature. This film formulation and orientation is suitable for pouch applications requiring an “easy-tear” linear tear feature and excellent hermetic seal properties.
摘要:
A laminate film including a first polyolefin heat sealable matte resin layer including a blend of 15-30 wt % metallocene-catalyzed butene-propylene elastomer and 85-70 wt % of a matte resin including ethylene homopolymer and propylene homopolymer or copolymer is disclosed. The laminate film could further have additional layers such as a second polyolefin resin-containing layer, a metal layer, or combinations thereof.
