Abstract

A method of sealing together polyolefin elements, the method comprising providing a first element including a polyolefin selected from at least one of polyethylene and isotactic polypropylene and a second element including a polyolefin selected from at least one of polyethylene and isotactic polypropylene, at least one of the first and second elements further including from 5 to 99 wt% syndiotactic polypropylene, and heat sealing the first and second elements together.
