Abstract
A laminated material suitable for use in inflatable playballs comprises a first layer of thermoplastic synthetic resin and a second layer. The second layer is formed of two thermoplastic resin materials, one having a tensile strength greater than the material of the first layer and forming a lattice structure and the other filling the interstices of the lattice structure, the filling material being exposed at one surface of the second layer and bonded at that surface to the first layer.
Claims18
A hollow article having a flexible wall consisting of laminated material comprising an outer first layer of thermoplastic synthetic resin material and an inner second layer comprising first and second thermoplastic synthetic resin materials;
- said first material having a tensile strength greater than said material of said first layer and said second material being exposed at one surface of said second layer and being bonded to the adjacent face of said first layer, and wherein each of said first and second materials form respective lattice structures which are mechanically interlocked, the material of one said structure filling the interstices of the other said structure.
