Abstract:
The present invention relates generally to a protective wrap and a protective envelope or pouch made therefrom, as well as the apparatus and process for forming such wraps and envelopes. Water-based heat-expandable adhesives (WBHEA) which include a plurality of heat-expandable microspheres are disposed in a pattern between web substrates on a continuous, high speed manufacturing line to produce padded, insulated products useful as envelopes, mailers and other protective packaging.

Claim (Index 9):
A method of manufacturing a protective padded pouch comprising:\n a.) providing a first web substrate having a length and width and a top side and a bottom side, which define a perimeter thereabout and an inner portion within the perimeter; b.) providing a second web substrate having a length and width and a top side and a bottom side which define a perimeter thereabout and an inner portion within the perimeter; c.) forming a sealable perimeter portion by applying a layer of sealing adhesive about the perimeter of the top side of the first web substrate to form a sealable perimeter portion d.) depositing a pattern of a water-based heat-expandable adhesive (WBHEA) on the inner portion within the perimeter of the top side of the first web substrate, the WBHEA forming a protective padded area when expanded;\n e.) forming a first two-layer laminate structure by mating the top side of the first web substrate with the bottom side of the second web substrate at their respective sealable perimeter portions to form one or more sealed seams having, the two layer laminated structure sealing the WBHEA therebetween, wherein the formation of the laminated structure does not substantially compress and substantially maintains the dimensions of the pattern of WBHEA prior to its expansion; \n f.) providing a third web substrate having a top and bottom, and a length and width which define a perimeter thereabout and an inner portion within the perimeter; \n g.) providing a fourth web substrate having a top side and a bottom side and a length and width which define a perimeter thereabout and an inner portion within the perimeter;\n h.) forming a sealable perimeter portion by applying a continuous sealing adhesive about the perimeter of the top side of the third web substrate to form a sealable perimeter portion; \n i.) depositing a pattern of a water-based heat-expandable adhesive (WBHEA) on the inner portion within the perimeter of the top side of the third web substrate, the WBHEA forming a protective padded area when expanded; \n j.) forming a second two-layer laminate structure by mating the top side of the third web substrate with the bottom side of the fourth web substrate at their respective sealable perimeter portions to form one or more sealed seams having the WBHEA therebetween, wherein the formation of the laminated structure does not substantially compress and substantially maintains the dimensions of the pattern of WBHEA prior to its expansion; \n k.) mating the first two-layer laminate structure with the second two-layer laminate structure to form a pouch having an open side. \n l.) exposing the thus formed protective padded pouch to sufficient RF radiation to expand and cure/coalesce the WBHEA between the first and second web substrates and between the third and fourth web substrates to form the protective padded pouch;\n m.) providing vents in the first and second two-layer laminate structures for water evaporation, wherein the vents may be formed from one or more of: gaps in the sealing adhesive; \n punctures in the perimeter portion(s) and perforations in the inner portion(s); and \n n.) optionally further processing the protective padded pouch to provide a desired uniformity in thickness and/or desired shape in at least one section of the protective padded pouch.
