A seam tape may be provided to independently and indirectly couple panels to create an inflatable product. Each panel includes a first substrate, and the seam tape includes a second substrate having a melt temperature that greater than a melt temperature of the first substrate. A method of adhering a seam tape, patch material, accessory material, or component material to a panel includes positioning the seam tape, patch material, accessory material, or component material on the panel such that the seam tape, patch material, accessory material, or component material receives more heat than the panel when adhering the seam tape, patch material, accessory material, or component material to the panel.

Provided is a process for preparing a zipper pouch, wherein the process comprises: A) forming a first laminate by a process comprising i) bringing together a polyisocyanate component and a polyol component to form an adhesive composition, ii) applying a layer of the adhesive composition to a layer of polyethylene terephthalate, iii) then contacting the layer of the adhesive composition with a layer of polyethylene having thickness of 80 micrometer or more; B) contacting a polymeric zipper construction to the first laminate at temperature of 200 C or higher. Also provided is a zipper pouch made by that process.

Provided is an ethylene-acrylic acid copolymer which may maintain high initial adhesive properties for a long time by having a zero shear viscosity (.sub.0) and a storage modulus (G) in specific ranges.

Disclosed is a method for manufacturing a separator having a polymer adhesive layer. The method includes preparing an aqueous polymer slurry comprising a particulate binder polymer having a glass transition temperature Tg of 20 C. or more and a particle size D50 of 300 to 800 nm, a wetting agent, and a particulate acrylic binder polymer having a glass transition temperature Tg of 10 C. or less and a particle size D50 of 100 to 200 nm, and coating the aqueous polymer slurry on at least one surface of a polyolefin-containing porous membrane having pores and drying the aqueous polymer slurry.
