ABSTRACT:
Disclosed is a resin composition for water-resistant and moisture-proof paper comprising 40 to 75 parts by weight of a polyolefin (A), 25 to 60 parts by weight of a tackifier (B) and 0 to 20 parts by weight of a compatibilizing agent (C), the total of (A), (B) and (C) being 100 parts by weight, and further blending 20 to 300 parts by weight of an inorganic filler (D) to 100 parts by weight of the sum of (A), (B) and (C). According to the present invention, the water-resistant and moisture-proof paper is provided at low cost which is disaggregated with ease by a pulper and recycled as paper materials.
