ABSTRACT:
The present invention is directed to melt blown polyolefin film which is produced cheaply by melt blowing polyolefin resins which contain 25 to 60 wt % fillers selected from the fillers including an inorganic carbonate, synthetic carbonates, nepheline syenite, talc, magnesium hydroxide, aluminum trihydrate, diatomaceous earth, mica, natural or synthetic silicas and calcined clays or mixtures thereof, having a particle size less than 150 mesh.
A further aspect of the present invention is directed to polyolefin resins, especially polyethylene, which are chemically degradable by the incorporation of the combination of the above group of fillers and a metal carboxylate. The metal carboxylates of the present invention are inclusive of a large number of metals, such as cerium, cobalt, iron, and magnesium.
