Title:
POLYOLEFIN-RESIN LAMINATED AND FOAMED SHEET
Document Type and Number:
Japanese Patent JP2005131952
Kind Code:
A
Abstract:

To provide a laminated and foamed sheet which can be easily torn in a TD direction without the use of a cutter etc.

In this laminated and foamed sheet 1 wherein an oriented film 3 is laminated on at least one side of a polyolefin resin-foamed sheet 2, tear strength in an MD direction as a longitudinal direction in the long wound state of the sheet 1 is made lower than tear strength in the TD direction orthogonal to the MD direction. In the sheet 1, when the MD-direction tear strength of the sheet 2 is higher than the TD-direction tear strength thereof, the oriented film 3, wherein the MD-direction tensile strength is lower than the TD-direction tensile strength, is used. Preferably, a uniaxially oriented film is used as the oriented film 3.
