複層型下敷きテープ
Document Type and Number:
Japanese Patent JP7142861
Kind Code:
B2
Abstract:
To provide an underlay tape in which an amount of an adhesive (glue) transferred from a rear face of a wall paper is less, in which construction can be proper and which can improve workability, in cutting an overlapped portion of wall papers.SOLUTION: A multi-layer type underlay tape is produced by: sandwiching a net-shaped sheet 4 between an upper layer film 2 and a lower layer film 3; and fixing the upper layer film 2 and the lower layer film 3 by adhesion only at both end portions together with the net-shaped sheet 4. The net-shaped sheet 4 is composed of warp 4B substantially parallel to a longer direction of the multi-layer type underlay tape and weft 4A which is substantially perpendicular to the warp 4B and crosses the multi-layer type underlay tape in a width direction. Material of the upper layer film 2 positioned at the wall paper side in cutting an overlapped portion of wall papers is polyolefin, and is especially preferably non-oriented polypropylene. The upper layer film 2 preferably includes uneven structure.SELECTED DRAWING: Figure 2
