Abstract: A recyclable, laminated polyolefin film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin films. The film structure has an energy cured coating layer or a two-part coating layer disposed on the outermost outward facing surface of the film structure and a printed ink layer on an interior surface of one of the polyolefin layers. In certain embodiments, the outermost surface of the laminated polyolefin film structure has a melting temperature which is at least 100 degrees Celsius, and more preferably 150 or 180 degrees Celsius, higher than a melting temperature of the innermost surface of the laminated polyolefin film structure.

Abstract: A packaging article includes an outer, intermediate, and inner paper plies. A first adhesive layer is disposed between the inner and intermediate paper plies for gluing the inner paper ply to the intermediate paper ply. A second adhesive layer is disposed between the intermediate and outer paper plies for gluing the intermediate paper ply to the outer paper ply. The first and second adhesive layers overlap and are coaligned. The outer, intermediate, and inner paper plies are adjoined to form a multiwall structure, wherein the first adhesive layer and the second adhesive layer are coaligned with each other on the multiwall structure. The first adhesive layer comprises a first plurality of adhesive spots and the second adhesive layer comprises a second plurality of adhesive spots, wherein the adhesive spots of the first plurality of adhesive spots do not overlap with the adhesive spots of the second plurality of adhesive spots.

Abstract: A method of forming a flexible packaging film includes providing a first web including a polymer sealant layer, the first web having a first major surface and a second major surface opposite the first major surface. A second web including a polymer outer layer is provided, the second web having a third major surface and a fourth major surface opposite the third major surface. An adhesive layer is applied to the second major surface and the first web is laminated to the third major surface. Prior to laminating the first web to the second web, one or more slits are formed in the second web.
