assignment In spite of its thinness and light weight, the present invention has a high elasticity and excellent handling properties, and thus can be preferably used for interlayers of electronic precision devices such as glass substrates, partition materials for containers, and cardboard substitutes for assembly container materials. It is an object to provide a resin foam sheet. Resolution The polyolefin resin foam sheet of the present invention is a polyolefin resin foam sheet having an appearance density of 60 to 350 g / L, a thickness of 0.2 to 1.5 mm and a basis weight of 50 to 200 g / m 2, and the flexural modulus of the base resin constituting the foam sheet is While being 300 MPa or more, the number of bubbles in the thickness direction of the foam sheet is 1-3. |
