Abstract
A resin which is an ethylene/α-olefin copolymer comprising ethylene and an α-olefin having 3 to 12 carbon atoms exhibiting particular physical properties including a narrow molecular weight distribution, and which is suitable for flexible sealed containers showing excellent flexibility, unstickiness and excellent slip properties, and flexible sealed containers therefrom.
Claims3
A flexible sealed container comprised of a resin which is an ethylene/α-olefin copolymer (A) comprising ethylene and an α-olefin having 3 to 12 carbon atoms, wherein said container is produced by injection molding and said ethylene/α-olefin copolymer (A) exhibits:
- (1) a density ranging from 0.900 to 0.930 g/cm3;
- (2) a melt flow rate determined under load of 2.16 kg at 190° C. which ranges from 10 to 80 g/10 min.;
- (3) a content of components soluble in n-decane at 23° C. which ranges from 0.1 to 2 wt %;
- (4) a molecular weight distribution (Mw/Mn) as measured by GPC which ranges from 1.5 to 3.5;
- and
- (5) an Olsen rigidity ranging from 500 to 3,500 g/cm2.
