摘要:
A tubular multilayer film including at least two, biaxially stretched tubular layers each formed of a polypropylene resin, wherein the innermost layer contains spherical antiblocking agent particles having an average particle size of 0.2 to 5 µm in an amount of 0.1 to 0.7 % by weight, and the outermost layer is free of the spherical antiblocking agent particles is disclosed. The multilayer film may be prepared by biaxially stretching a multilayer tubular raw sheet having an innermost polypropylene layer containing spherical antiblocking agent particles and an outermost polypropylene layer free of such antiblocking agent particles.
