- B32B 37/15 with at least one layer being manufactured and immediately laminated before reaching its stable state, e.g. in which a layer is extruded and laminated while in semi-molten state
- B32B 37/16 with all layers existing as coherent layers before laminating
- B32B 37/24 with at least one layer not being coherent before laminating, e.g. made up from granular material sprinkled onto a substrate (B32B37/15 takes precedence)
- B32B 37/26 with at least one layer which influences the bonding during the lamination process, e.g. release layers or pressure equalising layers
