Title:
STYRENIC RESIN MULTILAYER SHEET
Document Type and Number:
Japanese Patent JP2013022937
Kind Code:
A
Abstract:
To provide a sheet which is actually formed of only a styrene-diene block copolymer resin, has excellent transparency and flexibility, and causes no blocking in film formation even if neither a large amount of a lubricant nor a blocking preventing material is added.
There is provided the styrenic resin multilayer sheet formed by laminating 10-50 layers which are formed of the styrene-diene block copolymer resin, block copolymers having a mass average molecular weight (Mw) of 100,000-250,000 and individual average thicknesses of 5-30 μm. Prevention against blocking in film formation is effective on condition that the addition amount of the lubricant is equal to or smaller than 0.05 pt.mass.
