CURL PREVENTING METHOD IN LAMINATE PROCESSING

摘要

PURPOSE: To effectively prevent the curl of a laminate processing sheet after laminate processing in a method for laminating a molten resin to the upper surface of a base material based on paper. CONSTITUTION: In a method wherein a molten resin is extruded to the nip 34 between a pressure roll 30 and a cooling roll 32 from a T-die 42 to be laminated to the upper surface of a base material 1 based on paper, water applying treatment 20 is performed to the base material from the surface on the side opposite to the laminate processing surface of the base material immediately after the base material 1 is delivered by a delivery machine 10 before laminate processing to prevent the curl of the laminate processing sheet after laminate processing.
