<P>PROBLEM TO BE SOLVED: To provide a water-repellent packaging material which prevents an adhesive content such as a liquid or a semi-solid and gel material from adhering to or staying on the inner surface of the packaging materia, and which has excellent heat sealing property. <P>SOLUTION: The water-repellent packaging material is prepared by sequentially stacking, on at least one surface of a base material, a seal layer including a fine particle with the surface covered with a heat-sealable resin and a silane coupling agent, and a water-repellent layer including a hydrophobic silicone resin. That is, by covering the surface of the fine particles with the silane coupling agent, a silane cross-linked polymer layer is formed between the heat sealable resin and the fine particles, and the strength and the adhesion of the fine particles are improved. As a result, adhesive strength between the seal layer and the base material and between the seal layer and the water-repellent layer are improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
