Abstract
A packing material has a plurality of separable layers of pliable material. Each layer has a region containing a plurality of domes in a pattern extending in two directions. The plurality of domes are nested together in the region. The plurality of domes each have a top, a base and a side extending from the top to the base at an angle of divergence exceeding 10°. The plurality of domes have a dome height of at least ⅛ inch. Adjacently nested pairs of the domes have between them an overhead gap no greater than 10% of the dome height. The plurality of separable layers with the plurality of domes can be separated and disoriented to occupy a larger volume. These separable layers may be discrete layers, pleats in a web, or sections of a web.
Claims19
A packing material comprising:
- a plurality of separable layers of pliable material each having a region containing a plurality of domes in a pattern extending in two directions, said plurality of domes being nested together in said region, said plurality of domes each having a top, a base and a side extending from the top to the base at an angle of divergence exceeding 10°, said plurality of domes having a dome height of at least ⅛ inch, wherein first and second domes of adjacently nested pairs of the domes are differently sized and have between them an overhead gap no greater than 10% of the dome height, wherein said plurality of separable layers with the plurality of domes can be separated and disoriented to occupy a larger volume.
A packing material assembly comprising:
- a plurality of film layers disposed one on top of another as a stack and being individually separable, each of the layers including a plurality of domes in a pattern extending in two directions, each of the domes having a top, a base and a side extending from the top to the base at an angle of divergence, wherein each of the film layers has a thickness T at the base, a thickness t at the tops of each of the domes and a height H between a top surface of the top of each of the domes and a top surface of the base of each of the domes, wherein the domes of a first of the film layers are nested within or over the domes of a second of the layers, wherein the second layer overlies or underlies the first layer, wherein first and second domes of a pair of the adjacently nested domes are differently sized and have between them an overhead gap no greater than 10% of H, such that the height of the stack does not exceed:
- T+H+(L−1)*(t+10% H)
- where L is the number of film layers in the stack.
