<P>PROBLEM TO BE SOLVED: To provide a lid material of excellent drawing and packaging properties which uses no aluminum foil, and can be collected as plastics, or easily incinerated after the use. <P>SOLUTION: This lid material is a laminate film comprising at least a base layer and a heat seal layer. The base layer is formed of a resin composition of copolymer resin (A) of a specified composition of styrene monomer (a) and conjugate diene monomer (b), and copolymer resin (B) of polystyrene or acrylic monomer (c) and styrene monomer (d). In the lid material for draw molding, and a food vessel packaging body formed of the lid material, the ratio A/(A+B) is 0.70 to 0.90, and the ratio of the thickness of the base layer to the laminate film is 0.50 to 0.90. <P>COPYRIGHT: (C)2003,JPO |
