<P>PROBLEM TO BE SOLVED: To provide a packaging material having an excellent nonadherent surface preventing sticking and remaining of the content on an inner surface of a container and promoting stable maintenance of its performance in the packaging material of a molding container, a bag and the like mainly packaging liquid-containing food, cosmetic materials and the like. <P>SOLUTION: An anti-sticking particle coated layer 6 is formed on a surface of a packaging material base material 1 via a hot glue layer 5. The particle coated layer 6 is constituted of a mixed composition of a hydrophobic wet silica particle A and a hydrophobic or hydrophilic dry silica particle B at a predetermined combination ratio, and an impregnated adhesion strengthening layer 6a into which a heat sealing layer component has entered is formed on a part of the particle coated layer 6 by heat treatment. <P>COPYRIGHT: (C)2013,JPO&INPIT |
