(57) [Summary] [Problem] To provide a packaging material which is excellent in blocking property when wound and the like and has easy opening property. SOLUTION: The easy-opening packaging material of the present invention is an easy-opening packaging material comprising at least two thermoplastic resin layers having a base layer and a seal layer, and the seal layers are overlapped with each other to have a size of 100 mm × 100 mm. Apply a 25 kg load to the area Peeling off at a speed of 200 mm / min after chucking for 72 hours at 200 ° C. is 1 N / 100 mm or less. Further, it is a packaging material having easy-openability by using a low-crystalline polyester as a seal layer and a modified polyolefin layer as a base layer. The easily-openable packaging material of the present invention has a low blocking strength, can prevent the wound film from blocking, and has a wide heat sealing temperature range. |
