<p>PROBLEM TO BE SOLVED: To provide a lid material such as a heat seal lid material applied to a container for package of yogurt or the like, an adherence prevention layer 3 formed of hydrophobic inorganic fine particles 3a is provided on a rear surface of the lid, capable of efficiently preventing adherence of yogurt or the like which is content, and capable of improving adhesion of the adherence prevention layer 3, and preventing partial exfoliation efficiently, thereby adherence prevention effect can be stably and preferably maintained over a long period.SOLUTION: The lid material comprises at least a base material layer 1 and a heat sealing layer 2, and a content adherence prevention layer 3 is formed on an outer surface of the heat sealing layer 2 by a method for dispersing hydrophobic inorganic fine particles 3a into alcohol and coating the fine particles. The heat sealing layer 2 is formed of a resin composition including modified acrylic urethane resin as a main component and can be solved to the alcohol.</p> |
