Abstract
A packaging material used for a bag for transporting of a silicon material is a laminate in which a first resin base, barrier, second resin base, resin, and sealant layers are laminated in that order. A resin layer indentation elastic modulus is smaller than an indentation elastic modulus of each of the first and second resin base layers by one or more orders of magnitude, a sealant layer indentation elastic modulus is smaller than a first resin base layer indentation elastic modulus of and a second resin base layer indentation elastic modulus by one or more orders of magnitude, and a difference between the first resin base layer indentation elastic modulus and the second resin base layer indentation elastic modulus is smaller than a difference between the second resin base layer indentation elastic modulus and the indentation elastic modulus of the resin layer.
