PROBLEM TO BE SOLVED: To provide a lid material having favorable sealing performance and having content adhesion preventability, in particular, the lid material strong in mechanical strength and having productivity.SOLUTION: A lid material includes a laminate in which at least a base material layer, a thermobonding layer 6, a content adhesion preventing layer 7 are sequentially laminated. The content adhesion preventing layer contains spherical particles 8, hydrophobic oxide particulates 9, and a binder resin 10. The spherical particle 8 is a silicone resin of 3-30 μm in a mean particle size, the hydrophobic particulate 9 is hydrophobic silica of 5-20 μm in a mean particle size, and the binder resin 10 is one kind of polyethylene, polypropylene, polyester, ethylene-vinyl acetate copolymer, acryl, and styren-butadiene rubber or a mixture thereof. |
