B32B LAYERED PRODUCTS, i.e. PRODUCTS BUILT-UP OF STRATA OF FLAT OR NON-FLAT, e.g. CELLULAR OR HONEYCOMB, FORM
Description
B32B covers engineered materials and composite products constructed from two or more layers of different or identical materials bonded together. The classification encompasses laminates, sandwich structures, coated substrates, and multi-ply assemblies using flat, cellular, honeycomb, or other non-flat forms. Applications range from packaging films and adhesive tapes to structural composites, thermal insulation, sound-absorbing panels, and decorative laminates across construction, automotive, aerospace, and consumer goods industries. This subclass focuses on the material composition and layer structure itself rather than the manufacturing processes or end-use applications covered elsewhere.
