Abstract
Official abstract text for this publication.
Provided is a crosslinked polyolefin-based resin foam sheet of the present invention having a large number of foam cells, which is obtained by crosslinking and foaming a polyolefin-based resin, and in which the foaming ratio is 1.1 to 2.8 cm 3 /g, the average cell diameter in the MD of the foam cells is 150 to 250 μm, the average cell diameter in the CD is 120 to 300 μm, the ratio of the average cell diameter in the MD to the average cell diameter in the CD (MD/CD) of the foam cells is 0.75 to 1.25, and the ratio of the average cell diameter in the MD to the average cell diameter in the ZD (MD/ZD) is 1.9 to 7.0.
First claim
Opening claim text (preview).
1 . A crosslinked polyolefin-based resin foam sheet having plural foam cells, the foam sheet being obtained by crosslinking and foaming a polyolefin-based resin, wherein the foaming ratio is 1.1 to 2.8 cm 3 /g, the average cell diameter in MD of the foam cells is 150 to 250 μm, the average cell diameter in CD is 120 to 300 μm, the ratio of the average cell diameter in the MD to the average cell diameter in the CD (MD/CD) is 0.75 to 1.25, and the ratio of the average cell diameter in the MD to the average cell diameter in ZD (MD/ZD) is 1.9 to 7.0. 2 . The crosslinked polyolefin-based resin foam sheet according to claim 1 , wherein the thickness is 0.02 to 1.9 mm. 3 . The crosslinked polyolefin-based resin foam sheet according to claim 1 , wherein the polyolefin-based resin is a polyethylene-based resin. 4 . The crosslinked polyolefin-based resin foam sheet according to claim 3 , wherein the polyethylene-based resin is a polyethylene-based resin obtained using a metallocene compound as a polymerization catalyst, or an ethylene-vinyl acetate copolymer. 5 . An adhesive tape obtained by providing an adhesive layer on at least one surface of the crosslinked polyolefin-based resin foam sheet according to claim 1 . 6 . The adhesive tape according to claim 5 , wherein the thickness is 0.03 to 2.0 mm.
