Abstract
Polypropylene resins compounded with a maleated polyolefin (e.g., polyethylene or polypropylene) provide film compositions having improved adhesion to polyvinylidene chloride coatings and resistance to the deleterious effect of moisture upon adhesion thereby avoiding need of a primer coat. Specific embodiments include biaxially oriented polypropylene film made from polypropylene compounded with such a maleated polyolefin and directly coated with a polyvinylidene chloride coating.
