延伸フィルム
Document Type and Number:
Japanese Patent JP4323359
Kind Code:
B2
Abstract:
To provide an oriented film having excellent anti-fogging property and fusion-cut sealability.
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.
