PURPOSE:To keep freshness of early stage of packaging of marine paste product for a long period, by packaging the marine paste product into a composite film obtained by adding an anti-fogging agent to at least one of a substrate film layer and a heat seal layer, drawing the films in a combined state of the substrate film layer and the heat seal layer and treating the surface of the heat seal layer to be brought into contact with the marine paste product. CONSTITUTION:A marine paste product is packaged into a composite film formed in the following manner with keeping fixed space. Namely, at least one side of a thermoplastic polymer film layer constituting a substrate film layer is combined with a polymer film layer constituting a heat seal layer and the combined layers are drawn at least in one direction in a compounded state. At least one of the substrate layer and the heat seal layer is blended with an anti-fogging agent. The surface of the heat seal layer at the side to be brought into contact with the marine paste product is treated in such a way that wetting tension is >=36dye/cm. |
