Abstract
A method that includes the step of spraying a foamed hot melt adhesive from the discharge nozzle of a spray gun under such conditions that elongated strands of foamed hot melt adhesive are formed in an open weave film of spider web configuration which is deposited on a first substrate. A second substrate can then be bonded to the first to form a product. Alternatively, and before the second substrate is bonded to the first, a powder, e.g., a hygroscopic powder, can be deposited within the open areas of the film's spider web configuration to form a laminate product with a special enhanced characteristic, e.g., moisture absorbency.
