Method of manufacture of a light-weight gusset frame

摘要: A method of manufacturing a composite frame for side gusset bag. The has peripheral raised region and depressed central region. is made up moldable substrate, e.g. ethyl vinyl acetate foam, an outer layer wear-resistant material, e.g., high-denier nylon, or poly/nylon combination, and, preferably, inner adherent layer, the loop half hook-and-loop fabric. During process, flat sheet substrate covered on one by material other layer. Incisions are cut through substrate-adhered materials composite. then molded to provide region, with surface being material.
