The objective of the present invention is to provide a thermoplastic adhesive film capable of, in a thermobonding step of a laminated body of different materials used particularly in automobile members, electronic members, construction members, etc., such as a polypropylene resin material, a polyamide resin material, and a metal material such as aluminum or steel plates, preventing deformation of the resin material and peeling due to thermal history after molding. Provided as a solution is a thermoplastic adhesive film comprising a resin composition (D) which contains a thermoplastic olefin elastomer resin (A), an acid-modified polypropylene resin (B) and a nucleating agent (C).

The manufacturing of articles relies on the bonding of two or more components to form some forms of the articles, such as a shoe sole bonded with a shoe upper. The bonding may be achieved with an adhesive particulate that is applied to a surface of a substrate. The adhesive particulate is selectively fused to the substrate with a controlled energy source, such as a laser. The selective application of laser energy allows for specific geometric structures of adhesive particulate to be formed on the substrate. The substrate having the fused adhesive particulate is mated with another component allowing the fused adhesive particulate to bond the first substrate and the second component.
