LAMINATED BODY AND PACKAGING BAG

摘要

PROBLEM TO BE SOLVED: To provide a laminated body capable of suppressing deterioration of a heat seal layer due to the content and obtaining a packaging bag having no influence on the quality of the content. SOLUTION: The laminated body is provided with a barrier layer (B) on one side of a polyester-based resin film (A), the polyester-based resin film (C) on the barrier layer (B), and a heat seal layer (D) having 10-100μm thickness on the polyester-based resin film (C). The heat seal layer (D) applies a heat seal polyester-based resin solution having 5-100 poise of 40 mass% cyclohexanone solution viscosity at 25°C to the part for heat sealing with a screen printing method.
