PROBLEM TO BE SOLVED: To provide a polyethylene composition for flexible thin-wall containers excellent in moldability, flexibility, impact resistance and transparency and a container obtained with it.SOLUTION: A polyethylene composition for flexible thin-wall containers contains (C) 0.01-0.5 pt. wt. of a slip agent to 100 pts. wt. of a polyethylene (I) and has properties (a) to (e): (a) a melt flow rate(MFR) at a temperature of 190°C and a load of 2.16 kg is 5-100 g/10 min; (b) a density is 0.890-0.920 g/cm; (c) a flexural modulus of elasticity is 30-200 MPa; (d) a ratio of the tensile impact strength in the flow direction(MD) of the molten resin to the tensile impact strength in the direction(TD) perpendicular to the flow of the molten resin, MD strength/TD strength, is 0.10-1.00 for a molded test specimen of a thickness of 1 mm or smaller; and (e) a friction coefficient is 0.40 or smaller. |
