PROBLEM TO BE SOLVED: To provide a less expensive synthetic resin pallet not decreasing its performance by using a less expensive reproduced plastic material as a double layer structure of a skin layer and a core layer.;SOLUTION: A synthetic resin pallet is constituted by a skin layer of which at least a part of it is a surface layer and a core layer of an inner layer and this is molded by two kinds of resin. Then, in order to perform a molding operation, it is possible to mold the product by a molding method for molding a multilayer extrusion molded product, i.e., a so-called sandwich molding method or extruding resin of the skin layer becoming the surface layer within a cavity of a die and then extruding resin of the core layer as the inner layer under application of one point gate system in which a gate segment arranges one point gate at a substantial central location of a deck board. It is possible that the core layer occupies about 10 to 70 wt.% of the entire layer.;COPYRIGHT: (C)2003,JPO
