<p>PURPOSE:To obtain the laminated material excellent in sanitary properties, an aptitude for after-working and the like and suitable for forming a can vessel by a method wherein a metallic plate and a thermoplastic resin film are laminated through a bonding agent made by blending polyolefin containing carboxyl group and a metal compound. CONSTITUTION:Olefin series individual such as ethylene or the like and alpha,beta-unsaturated carboxylic acid such as acrylic acid or the like are copolymerized or graft polymerized in a proportion of preferably 100:0.1-30wt. ratio to obtain the polyolefin containing carboxyl group. Subsequently, preferably 0.05-10 parts of the metal compound such as potassium carbonate or the like is used against 100 parts of polyolefin and is heated and mixed uniformly under the temperature of 120- 220 deg.C for 5-120min to obtain the polyolefin composition. This composition is fused and extruded by a T-die 6 and the metallic plate 1 and the thermoplastic resin film 3 are pressed by a cooling roller 2 and a nip roller 5 to bond them, thereby obtaining the objective laminated plate.</p> |
