The suitcases, suitcases and other materials are mostly metal composite materials: the point is that the structure is firm but the weight is not light and the cost is high; in addition, the box material is made of multi-layer plastic materials, although the practice is; = the advantage of cheap 'but the structural strength is not the same as that of the metal composite material, 'for example - acrylonitrile butadi, styrene, which is commonly used in the manufacture of suitcases or suitcases. ABSH is the material. The ABS material itself has anti-wear properties, but it has limited grinding force. Furthermore, the luggage made of ABS material is easily deformed or broken by the impact material during transportation. - Aspects 'Multilayer materials are also used in the manufacture of sports equipment, such as the outer layer of sports and entertainment boards. The foamed anger layer structure disclosed in U.S. Patent No. 5,211,593 has an embossing pattern." To bond to the surface of the foamed core layer, and it has a multi-layered plastic layer. In addition, Wu Guo Patent 6, _, 351 further discloses a kind of composite panel with a multi-layered skin 5 1270461 #娱乐板; basically, its The outer skin is formed by laminating a layer of thin flue-cured tobacco material, a layer of polyethylene foaming material and a layer of mixed foaming material of polystyrene and polyethylene. SUMMARY OF THE INVENTION The object of the present invention is to disclose a light junction , sturdy and low-cost multi-layer material.
