A polyolefin-based mat film or sheet can be preared from a polymeric blend of the preset invention comprising a propylene polymer or copolymer as component (A) and a specific ethylene-α-olefin copolymer (VLDPE, so-called "super low-density polyethylene") as component (B). The polymeric blend may further comprise a high-pressure radical polymerization process ethylene polymer or copolymer and /or a modified polyolefin-based resin as component (C). The above blend of the present invention may further comprise an inorganic filler as component (D) and a flame retardant as component (E). The mat films or sheets prepared from these polymeric blends are excellent in tensile modulus, flexibility, impact resistance, thermal resistance, laminating properties, flame resistance, chalking resistance, covering power, scratch resistance, and widely used for fabricating adhesive tapes, covers or cases for stationeries, fashion bags, sheets for interior finish work in construction and automobile industries, and sheets for dressing steel plates. |
