PACKAGING PRODUCT WITH THERMAL AND MECHANICAL INSULATION FEATURES

摘要

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.

主权项

1. An insulating packaging material, comprising:
a first multi-layer film including a first polymer layer and a first metallized layer; and a second multi-layer film including a second polymer layer and a second 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 hexagonal shapes .
