Abstract
A pressure-sensitive adhesive sheet with a release liner has a bubbles containing pressure-sensitive adhesive layer and a release liner in contact with at least one surface of the bubbles containing pressure-sensitive adhesive layer. The release liner comprises at least three layers including an intermediate layer and surface layers, and the surface layers are positioned on both surfaces of the intermediate layer. The intermediate layer comprises at least one polyolefin resin. Each of the surface layers comprises a low-density polyethylene and an olefinic elastomer and independently has a thickness of 15 μm or less. The ratio of the thickness of the intermediate layer to the total thickness of the surface layers (the intermediate layer/the surface layers) is in the range of 4 to 19.
