Abstract
A polyolefin blend having in a range of 40 to less than 90% by weight of a high modulus, isotactic polypropylene; and in a range of 10 to 60% by weight of a 1-butene/ethylene copolymer; the 1-butene/ethylene copolymer having about 0.5 to about 10 wt % of an ethylene. A polyolefin blend can be in a form of a transparent, oriented film having a biaxially oriented layer with an oxygen transmission rate of at least about 200 cc/100 sq. in./day/atmosphere (3077 cc/sq. m./24h/atmosphere), a tensile modulus of at least about 160,000 psi (1.103 GPa) and a haze value of no greater than about 3% measured at a thickness of about 1 mil (25 μm).
