PROBLEM TO BE SOLVED: To provide a heat-sealant layer which checks the adsorption of components, maintains drug components, and has a sealing function by constituting the heat-sealant layer in a laminate with saturated polyester whose glass transition temperature is specified. SOLUTION: In a laminate composed of a heat-sealant layer, a barrier layer, and a backing film, the glass transition temperature of the heat sealant layer is 40-100 deg.C, a laminate for sweat control packaging constituted with amorphous- low-crystalline saturated polyester. The barrier layer is constituted by mounting metal foil or a vapor deposition film on a plastic film. The laminate 5 for sweat control packaging in which each layer interval consisting of the heat- sealant layer 4, the barrier layer 3 and the backing film is laminated by adhesive layers 22, 21. The barrier layer is to shut off the passage of light, oxygen, and drug components and uses the metal foil of aluminum, copper, iron, etc., 7-60μm in thickness.
