Abstract
Polypropylene random copolymer resins and metallized, heat sealable cast films produced from such resins include (1) a polypropylene-.alpha.-olefin random copolymer such as a propylene-butene-1 or propylene-ethylene random copolymer and (2) an additive package including a synthetic amorphous silica, a hindered phenolic antioxidant, a processing stabilizer and an acid acceptor. The compositions according to the invention are useful for the preparation of metallized, heat sealable packaging films suitable for protecting goods, particularly goods requiring a long shelf life such as foods or semiconductor products.
