Title:
POLYOLEFIN COMPOSITE FILM
Document Type and Number:
Japanese Patent JP3508223
Kind Code:
B2
Abstract:
PURPOSE: To improve the transparency, slidable property and film windable property by laying a surface layer of a fine particle-containing polyolefin polymer which contains specified parts by weight of an organic polymer fine particle 1 having a specified average particle diameter and specified parts by weight of an organic polymer fine particle 2 having a diameter larger than that of the fine particle 1 based on specified parts by weight of a polyolefin polymer.
CONSTITUTION: In a structure of a polyolefin composite film, on at least one face of a base layer having as a main component a polyolefin polymer, a surface layer consisting of a fine particle-containing polyolefin polymer which contains 0.01-1 pts.wt. of an organic polymer fine particle l having an average particle diameter of 0.1-1.5μm and 0.005-0.5 pts.wt. of an organic polymer fine particle 2 having an average particle diameter of 1.5-7μm and a particle diameter larger than that of the fine particle 1 based on 100 pts.wt. of the polyolefin polymer is layered. For the fine particles 1 and 2, a particle whose water drop holding time is 10sec. or over is used so as to develop their characteristics more effectively and more stably.
