Abstract
The invention relates to a low-density polyethylene resin for laminates, a composition thereof, and a laminate and production method therefor. The low-density polyethylene resin is one obtainable by a high pressure radical polymerization method and has a density of 0.910 to 0.935 g/cm , a melt flow rate of 0.1 to 300 g/10 min., and a terminal vinyl group number of 0.4 or more per 1,000 carbon atoms. According to the invention, a laminate having high interlayer adhesion strength can be obtained also by low-temperature, high-speed molding so that the occurrence of smoking and odor can be prevented. Also, the resin is excellent in productivity and economics. Further, the resin is excellent in productivity and economics because it can be readily made thinner. The laminate is suitable for application to, for example, food wrapping materials, containers, etc.
