摘要： PROBLEM TO BE SOLVED: To provide an oriented film having excellent anti-fogging property and fusion-cut sealability.
SOLUTION: This oriented film is structured of a layer (A) containing 0.5 to 5 pts. mass amorphous polyolefin polymerized by a metallocene catalyst and 0.2 to 4 pts. mass anti-fogging agent to 100 pts. mass homopolypropylene resin with an NMR pentad fraction of 93 to 98% and (B) a layer made of propylene random copolymer obtained by copolymerizing 1.5 to 8 mol % α-olefin with not more than 4 carbon atoms, laminated in the order of (B)/(A)/(B). Thus it is possible to manufacture bags taking advantage of high fusion-cut sealing strength, which is useful for the manufacture of a packaging bag for fresh vegetables.

摘要： PROBLEM TO BE SOLVED: To provide a release sheet the prime objective of which is not to cause a defective release due to static, when polyurethane is peeled off. SOLUTION: The release sheet is used for a process paper in the formation of resin films and includes a polypropylene base layer A and a matte resin layer B containing a polymer-based antistatic agent arranged on the polypropylene base layer A. An intermediate layer C is provided between the polypropylene base layer A and the matte resin layer B. As the matte resin layer B includes the polymer-based antistatic agent, a lasting and durable antistatic effect is available without applying a corona treatment, and by extension, the polyurethane is easy to peel, hardly flawed, and does not cause defects.
