  • Publication number: 20030236334
    Abstract: An extrudable polypropylene blend combined with resins in precise amounts so that the resultant extruded film is easier to glue and is useable with hot melt adhesives. Mixtures of polypropylene and low density polyethylene are normally considered incompatible, but the contemplated blends which include 10-30% low-density polyethylene mixed with polypropylene give resin combinations runnable on a coater extruder and they produce a film having the advantages of polypropylene but which are no more difficult to glue than a film of low-density polyethylene.
