A coated packaging film suitable for packages

Abstract

The present invention relates to a coated packaging film comprising: (1) A heat sealable substrate having a heat sealable area and an opposite surface that is on the opposite side to the heat sealable area, (2) A heat resistant coating disposed on at least a part of said opposite surface of the substrate, wherein the heat resistant coating comprises: (I) One or more polymers (I) having a glass transition temperature Tg1 of at least 140° C., and (II) One or more polymers (II) having a glass transition temperature Tg2 of at most 50° C., wherein the difference between Tg1 and Tg2 is at least 100° C., wherein the Tg1 and Tg2 are determined with Differential Scanning Calorimetry as described in the description, and wherein the substrate consists of at least 60 wt. % of polymer selected from the group consisting of polyethylene (PE), oriented polyethylene and any combination thereof, based on the total weight of the substrate.
