MULTILAYER RECYCLABLE ULTRASONICALLY WELDED FILMS

Abstract:

Embodiments herein relate to multilayer recyclable films for food packaging. In an embodiment, a multilayer packaging film is included with a first polymeric layer, a second polymeric layer, and a third polymeric layer. The first layer and the third layer can directly contact opposite sides of the second layer. The first layer and the third layer can be directly bonded to the second layer via a welding process. The first polymeric layer, the second polymeric layer, and the third polymeric layer can each contain the same thermoplastic polymer. The second polymeric layer can include an amount of a functional additive that is different than the first and third polymeric layers. Other embodiments are also included herein.
