<p>PROBLEM TO BE SOLVED: To provide lid material mainly applied to a container for packaging yogurt which can effectively prevent sticking of the yogurt as content on a back surface of a lid while suitably maintaining a heat sealing property and a tight sealing property.SOLUTION: A sticking preventing layer 6 formed of hydrophobic fine particles 10 is formed on an outer surface of a heat-sealing layer 5 laminated on a base material layer 1. The hydrophobic fine particles is once excessively coated on a surface of the heat-sealing layer 5, and after drying it, surplus fine particles including free fine particles are removed by wiping the surface. Thereby, the sticking preventing layer 6 is formed in a thin layer having uniform fine particle distribution with residual fine particles.</p> |
