Abstract
A packaging product taking the form of a thermally insulating packaging material includes a first multi-layer film bonded to a second layer of multi-layer film. Each multi-layer film can include one or more polymer layers and one or more metallized layers. The multi-layer films are bonded to each other with a pattern that leaves a number of inflatable cells dispersed across a surface of the sheet. At least one end of the sheet can be left unbonded. The uninflated packaging product can be stored and distributed in its uninflated state prior to it being used as a packaging material. Once ready for use, the cells can be inflated through the unbonded ends and the unbonded ends of the sheets can then be sealed to form a robust sheet of thermally insulating packaging material.
Claims20
An insulating packaging material, comprising:
- a first multi-layer film including a first polymer layer;
- and
- a second multi-layer film including a second polymer layer and a metallized layer, wherein the first multi-layer film is joined to the second multi-layer film over a bonded region, the bonded region being interspersed with unbonded regions that when filled with gas form an array of adjacent cells.
A thermally insulating packaging material, comprising:
- a plurality of multi-layer films, each one of the multi-layer films including a polymer layer, the plurality of multi-layer films comprising:
- a first multi-layer film having a metallized layer, and
- a second multi-layer film, a portion of the first multi-layer film being bonded to a portion of the second multi-layer film at a bonded region, the bonded region having a pattern that leaves an unbonded region defining a number of adjacent inflatable cells arranged in a uniform pattern.
An inflatable packaging product, comprising:
- a first layer, comprising a first polymer layer defining an oxygen barrier layer and a metallized layer joined to the first polymer layer;
- a second layer, comprising a second polymer layer defining an oxygen barrier layer,
- wherein a portion of the metallized layer is joined directly to the second layer, the joined portion of the metallized layer defining an unbonded region that includes a plurality of connected inflatable cells, each of the plurality of connected inflatable cells being in fluid communication with each other.
