LAMINATE AND CONTAINER USING IT

摘要

PROBLEM TO BE SOLVED: To provide a laminate having uniformity of coating, completeness of the coating and adhesive properties as well as excellent modability and productivity to provide a resin layer containing polyester as a main body in a base of metal or the like, and a seamless can formed of the laminate. SOLUTION: This laminate is obtained by laminating resin containing polyester as a main body on a base. In this case, the resin layer has following formula R at the time of melt extruding: R=η12.2 /η1216 where a melt viscosity ratio (R) defined by a melt viscosity ofη12.2 at a shearing speed of 12.2sec<-1> at an extruding temperature of the polyester, and a melt viscosity ofη1216 at a shearing speed of 1216sec<-1> at an extruding temperature of the polyester is in a range of 2.0 or more, andη1216 is in a range of 500 poise or more. After the resin layer is melt extruded, it is quenched.
