Abstract: PROBLEM TO BE SOLVED: To provide a composite volume-reducible container which is sufficient in mechanical strength in service and easily torn in disposal to reduce its volume by providing an easily-tearable layer having a specified tearing strength and consisting of specified resin components and a synthetic resin layer laminated thereon, and setting the peeling strength of the synthetic resin layer to be within a specified range. SOLUTION: A synthetic resin layer laminated on an easily-tearable layer is partly or wholly laminated on one or both surfaces of the easily-tearable layer. The easily-tearable layer is obtained by forming the resin components containing, by weight, 60-95% styrene resin and 40-5% olefin resin. The peeling strength of the synthetic resin layer is preferably 0.5-1.5 kg/15 mm, and the synthetic resin layer can prevent a flange part of a container from being curled up, and can be easily peeled when the container is disposed. The Elmendorf tearing strength of the easily-tearable layer is preferably 10-100f, the mechanical strength of the container can be increased, the easy tearability can be maintained, and the volume of the container can be easily reduced when it is disposed.
