Ski structure obtained from a polyamide based thermoplastic elastomer and grafted copolyolefin based film adapted for adhesion

A ski produced by a process comprising the steps of:

• adhering a first element having a junction surface to at least a second element having a junction surface by placing at least one adhesive layer between junction surfaces of said first element and said second element, and placing at least one thermoplastic film having a composition comprising
• A. At least 50 percent by weight of a polyamide-based thermoplastic elastomer selected from the group consisting of polymether amides and polyetherester amides, and
• B. An olefin copolymer comprising at least two different olefin monomers grafted with a member selected from the group consisting of carboxylic acid, an anhydride of carboxylic acid or a salt of carboxylic acid, between said adhesive layer and the junction surface of said first element, to result in a ski structure.
