PROBLEM TO BE SOLVED: To provide a polypropylene resin mat capable of being recycled which is excellent in heat resistance, cold resistance, slip resistance, and ink transfer resistance. SOLUTION: This polypropylene resin mat is composed of a polypropylene resin layer and a soft polypropylene layer. Preferable soft polypropylene resins include polypropylene resin composed of (A) 100-20wt.% resin consisting of homopolymer of propylene wherein rrrr/(1-mmmm)×100 is 20-60% in pentad fraction by isotopic carbon nuclear magnetic resonance (<13> C-NMR), and fused enthalpy (ΔH) measured with DSC is 10-100J/g or a copolymer containing 4wt.% or under of other olefin unit, and (B) 0-80wt.% propylene copolymer containing 10-80wt.% of olefin unit other than propylene.
