POLYOLEFINIC RESIN LAMINATED SHEET AND PTP PACKAGE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a polyolefinic resin laminated sheet improved in molding processability and oil resistance and suitably used as a PTP package or the like excellent in the balance of hand cutting properties and transparency. SOLUTION: The polyolefinic resin laminated sheet comprises an A-layer, which constitutes an intermediate layer and the B-layers laminated on both sides of the A-layer as outer layers. The A-layer and the B-layers mainly consist of a cycloolefinic resin (a) and a polyethylenic resin (b) and the mixing mass ratio of both resins is (a)/(b)=60-100/0-40 mass% in the A-layer and (a)/(b)=5-40/60-95 mass% in the B-layers. The component (a) is dispersed in the B-layers and the average dispersing particle size thereof is 0.2-1.0μm. The thickness of the A-layer of the laminated sheet is 60-95% of the total thickness of the laminated sheet. COPYRIGHT: (C)2007,JPO&INPIT
