Abstract
Laminating resin compositions of the invention enable excellent productivity in the lamination processes, and are free from deterioration in optical characteristics such as transparency or surface properties inherent to resins such as polypropylenes. Multilayer structures obtained by laminating the composition on a substrate have tear strength which is as high as that of multilayer structures obtained by simply laminating a polyolefin resin such as polypropylene on a substrate. The laminating resin composition includes a polyolefin resin and a polyethylene wax having a density in the range of 890 to 955 kg/mas measured by a density gradient tube method in accordance with JIS K 7112 and a number average molecular weight (Mn) in terms of polyethylene in the range of 500 to 2900 as measured by gel permeation chromatography (GPC).
