Peelable, non-sticky, heat-sealable film for packaging fatty and pasty foods

摘要

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.

1. 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; wherein the core layer contains a release agent for diffusion toward the interior skin layer; wherein the peeling agent in the peelable layer has a saturation capacity for the release agent and the release agent is present in the core layer in a quantity which is greater than said saturation capacity; and wherein the core layer contains the release agent in a concentration (Pc) which is greater than 0.5×Tp×(Pp/Tc), wherein Tp is the thickness of the peelable layer, Pp is the concentration of peeling agent in the peelable layer, and Tc is the thickness of the core layer.
