Abstract
A polypropylene closure arrangement for flexible packages comprises a blend having a polypropylene random copolymer as a base resin with a flexible modifier, and a slip component. The polypropylene closure arrangement 10, 110 is sufficiently flexible to be extruded and coiled around guide wheels similar to the fusion process of a polyethylene closure arrangement. The polypropylene closure arrangement in accordance with the present invention has the ability to be fusibly attached to a polypropylene film or other fusibly compatible thermoplastic material launch conditions.
