LID MATERIAL FOR PREVENTING DEPOSITION OF CONTENT, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a lid material mainly applied to a yogurt container, which preferably maintains heat sealing property and tightness, and further effectively prevents deposition of yogurt as the content, on the backside of a lid.

SOLUTION: A deposition-preventing layer 6 made of hydrophobic particles 10 is formed on the outer surface of a heat sealing layer 5 laminated on a base material layer 1. The deposition-preventing layer 6 has a thin layer formed of hydrophobic wet silica particles made by imparting hydrophobicity to wet silica particles and having an average particle size of 2.0-7.0 μm, and having a uniform particle distribution in which the silica particles adhere at an rate of 0.1-1.0 g/m2.
