ABSTRACT:
The present invention relates generally to a multi-layer lidding film and a package with the lidding film heat-sealed thereto as a cover. The multi-layer film comprises: 1) a support layer, such as polyester, 2) a non-crosslinked amorphous acrylic interface layer, and 3) an outer copolyester heat seal layer. The acrylic interface layer advantageously limits the peel strength of the heat seal, making it easy for consumers to open the lidded package while still provides heat seal reliability and allowing the film to be heat-sealed to the package.
