  • Peelable puncture-resistant film for packaging
    Patent number: 9694564
    Abstract: A heat-sealable polymer-based multilayer film for peelable packaging comprising a polymer-based core layer having an interior-facing side and an exterior-facing side; a peelable intermediate layer on the interior-facing side of the core layer, the peelable layer having an interior-facing side and a core-facing side, and the peelable layer containing a peeling agent; and an interior skin layer on the interior-facing side of the peelable layer; wherein the core layer is polypropylene-based and contains a propylene-ethylene copolymer to impart puncture-resistance to the multilayer film.
    Type: Grant

  • Peelable, non-sticky, heat-sealable film for packaging fatty and pasty foods
    Patent number: 9434138
    Abstract: A heat-sealable polymer-based multilayer film for peelably and releasably packaging pasty or fatty foods comprising a polymer-based core layer having a food-facing side and an exterior-facing side, a peelable layer on the food-facing side of the core layer, the peelable layer having a food-facing side and a core-facing side, and the peelable layer containing a peeling agent, and an interior skin layer on the food-facing side of the peelable layer, the interior skin layer having a food-facing side and a core-facing side. The core layer contains a release agent for diffusion toward the interior skin layer, and the release agent is present in the core layer in a quantity which is greater than the saturation capacity of peeling agent in the peelable layer for the release agent.

  • PEELABLE, NON-STICKY, HEAT-SEALABLE FILM FOR PACKAGING FATTY AND PASTY FOODS
    Publication number: 20150298435
    Abstract: A heat-sealable polymer-based multilayer film for peelably and releasably packaging pasty or fatty foods comprising a polymer-based core layer having a food-facing side and an exterior-facing side, a peelable layer on the food-facing side of the core layer, the peelable layer having a food-facing side and a core-facing side, and the peelable layer containing a peeling agent, and an interior skin layer on the food-facing side of the peelable layer, the interior skin layer having a food-facing side and a core-facing side. The core layer contains a release agent for diffusion toward the interior skin layer, and the release agent is present in the core layer in a quantity which is greater than the saturation capacity of peeling agent in the peelable layer for the release agent.

  • Heat sealed polymeric films
    Patent number: 6235143
    Abstract: A method of heat sealing a heat sealable multilayer film having a first film surface which is heat sealable to itself or to other surfaces and a second film surface including particles of a cross-linked polymethyl methacrylate as an antiblock agent, the method comprising sliding the said second film surface over a heated heat sealing surface before effecting heat sealing of the film to itself or to another surface using said heated heat sealing surface.
