<P>PROBLEM TO BE SOLVED: To provide a film for stretch labels, which is excellent in self-flexibility, stiffness and processability when the film is formed. <P>SOLUTION: The film for stretch labels contains 50-90 wt.% of an ethylene-α-olefin copolymer (A) satisfying the following conditions (a1), (a2) and (a3) and 10-50 wt.% of an ethylene-α-olefin copolymer (B) satisfying the following conditions (b1), (b2) and (b3). The condition (a1) is that the activation energy of fluidization is ≥40 kJ/mol; the condition (a2) is that the molecular weight distribution is 5-25; and the condition (a3) is that the melt flow rate is 0.9-3 g/10 minutes. The condition (b1) is that the activation energy of fluidization is ≤35 kJ/mol; the condition (b2) is that the melt flow rate is 2-10 g/10 minutes; and the condition (b3) is that the density is 900-915 kg/m<SP POS="POST">3</SP>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
