Abstract:
A package is defined by a rigid base member and a peripheral flange surface. A flexible lidding member is heat sealed to the flange. The lidding member includes a first layer having a perimeter portion fixed to the flange and a second layer adhered to the first layer. An adhesive layer includes a permanent adhesive central portion and a perimeter pressure sensitive adhesive portion overlapping with the flange. A central score line is provided within the first layer, surrounding the central adhesive portion. A tab portion is formed as part of the perimeter portion of the lidding member and includes an edge score line formed in the first layer directly adjacent the fixed perimeter portion of the first layer.
