A bodyboard (50) with skins (56, 58) covering the top and bottom surfaces of a foam plank that forms a core (52) in the bodyboard. The top skin (56) is prepared by heat-expanding a foamable matrix layer having a polyolefin film deposited on the top surface of the matrix layer. With the application of heat, the matrix layer becomes a foam, and the polyolefin film softens and integrates with the foam. Graphics carried internally on the film become an integral part of the foam.

Une planche épaisse de mousse dont les surfaces supérieure et inférieure sont recouvertes de peaux (56, 58) forme l'âme (52) d'une planche de surf. On prépare la peau (56) de la surface supérieure par dilatation thermique d'une couche expansible de la matrice, sur la surface supérieure de laquelle on a déposé un film de polyoléfine. Avec l'application de la chaleur, la couche de la matrice devient une mousse, et le film de polyoléfine s'amollit et s'intègre dans la mousse. Des graphismes incorporés dans le film s'intègrent ainsi dans la mousse.
