Abstract
Insulated packaging is provided including an inner substrate and an outer substrate attached to the inner substrate to form an air gap therebetween. An expandable material including expandable microspheres is provided with the expandable material disposed between the inner substrate and the outer substrate. An adhesive material different than the expandable material is disposed between the inner substrate and the outer substrate to attach the inner substrate to the outer substrate. A method for forming the insulated packaging is also provided.
Claims19
A method of making insulated packaging, the method comprising:
- applying a thermally expandable material to at least one of a first substrate and a second substrate for being disposed therebetween, the expandable material comprising microspheres;
- applying an adhesive material different than the expandable material to at least one of the first substrate and the second substrate for being disposed therebetween at locations where the adhesive material does not overlap the thermally expandable material;
- attaching the first substrate to the second substrate with the adhesive material therebetween;
- and
- expanding the expandable material by expanding the microspheres thereof.
