PURPOSE: To obtain a flexible separation sheet not getting out of shape and having a surface showing resistance against depression, wrinkles and deformation by providing a nonwoven spunbonded central fabric layer having a specific wt. and providing polypropylene impermeable flat outer layers specified in thickness to both surfaces of the central fabric layer to specify the wall thickness of the sheet. CONSTITUTION: Separation sheets 14, 15 are used in order to separate rows of containers during packing and transport and have a nonwoven spunbonded central fabric layer having a wt. of about 170.1-311.85 g per 91.44 cm<2> and polypropylene impermeable flat outer layers with a thickness of about 0.0254-0.1016 mm are provided to both surfaces of the central fabric layer and a wall thickness is set to about 0.508-1.016 mm. One of the edge parts of the separation sheets 14, 15 is hermetically sealed by partial melting. |
