    摘要： 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/cm3, 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.

    摘要翻译： 本发明涉及层压板用低密度聚乙烯树脂及其组合物及其制造方法。 低密度聚乙烯树脂是通过高压自由基聚合法获得的，密度为0.910〜0.935g / cm 3，熔体流动速率为0.1〜300g / 10min，末端乙烯基数为0.4 或更多的每1000个碳原子。 根据本发明，也可以通过低温高速成型获得具有高层间粘合强度的层压体，从而可以防止吸烟和气味的发生。 此外，树脂的生产率和经济性优异。 此外，由于可以容易地使树脂变薄，所以树脂的生产率和经济性优异。 该层压板适用于例如食品包装材料，容器等。
