More Information
Summary:Provided is a heating pouch that can be heated in hot water and in a microwave. That is, the heating pouch includes a bag sheet provided with an easy peel pressure releasing seal part. In the pressure releasing seal part, one part of a sheet constituting the bag sheet and another part thereof are adhered so as to overlap each other. The pressure releasing seal part peels off when internal pressure rises, to form a degassing passage that communicates between an inside and an outside of the bag sheet. The pressure releasing seal part is provided with an easy peel layer and a skin layer. The skin layer is a resin layer constituting a seal surface that coats at least one of the one part and the other part of the sheet and which adheres to the other part which is not coated. The skin layer has a higher seal strength at 100 degrees centigrade than the easy peel layer.
