Abstract
A thermoformed cushioning material, a method of making and products formed with the cushioning material are provided herein.
Claims52
A sheet of cushioning material, comprising:
- a first layer comprising a polymeric material, the first layer comprising an upper surface and a lower surface;
- and
- a plurality of resiliently deformable spaced apart cushioning elements disposed in the polymeric layer, the cushioning elements comprising a sidewall extending upwardly from the polymeric layer to an upper surface, and an interior chamber defined by the sidewall and upper surface.
A continuous method of thermoforming a cushioning material, comprising:
- introducing a first continuous source of polymeric material into a thermoformer;
- heating the polymeric material;
- and
- molding a plurality of resiliently deformable cushioning elements disposed in the polymeric material, the cushioning elements defining an interior chamber comprising an upper region spaced apart from the polymeric layer and a sidewall extending upwardly from the polymeric layer to the upper region.
