THERMOPLASTIC FILMS AND PRODUCTS WITH DIFFUSION-BASED COMPARTMENTALIZED ADDITIVE COMPONENTS

The present disclosure relates to thermoplastic films and products formed therefrom that include additive components effectively compartmentalized based on diffusion characteristics of the additive components. For example, first and second additive components are localized on a thermoplastic film in a manner that as the additive components diffuse, they minimize or avoid interaction. Specifically, the thermoplastic film is folded over itself to create an air gap that causes the additive components to desorb, diffuse into the air gap, and then absorb into the film at a position across the air gap rather than diffusing substantially laterally across the thermoplastic film. By ensuring that the additive components diffuse up and down rather than laterally and by laterally offsetting the additive components, one or more implementations effectively compartmentalize the antagonistic components.

MULTIWALL PAPER PACKAGING STRUCTURES

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.
