“Duralong Double” is a board of excellent quality; the two layers are laminated in the various colours with a special adhesive, plasticizer free and with neutral pH. The board is laminated prior to the die cutting process; die cutting when the board is still damp from laminating means that the board does not break and crack. Duralong Double board is a board suitable for long-term conservation, offering the combination of strength and durability, ideal as a support or for the manufacturing of containers.
