POLYETHYLENE MULTILLAYER BASE MATERIAL, PRINTING BASE MATERIAL, MULTILAYER BODY AND PACKAGING MATERIAL

A polyethylene multilayer base material which is sequentially provided with a first polyethylene layer, a second polyethylene layer and a third polyethylene layer in this order in the thickness direction, and which is obtained by drawing, while satisfying the requirement (A) and/or the requirement (B). Requirement (A): The indentation elastic modulus of the first polyethylene layer is not less than 3.0 times the indentation elastic modulus of the second polyethylene layer; and the indentation elastic modulus of the third polyethylene layer is not less than 3.0 times the indentation elastic modulus of the second polyethylene layer. Requirement (B): The indentation hardness of the first polyethylene layer is not less than 2.0 times the indentation hardness of the second polyethylene layer; and the indentation hardness of the third polyethylene layer is not less than 2.0 times the indentation hardness of the second polyethylene layer.
