摘要: A laminating propylene/1-butene random copolymer composition comprising a propylene/1-butene random copolymer and a low-density polyethylene in a specified proportion. With respect to the propylene/1-butene random copolymer, the content of structural units derived from propylene, content of structural units derived from 1-butene, MFR, Mw/Mn and B-value as a parameter indicating the randomness of copolymer monomer chain distribution fall within specified ranges. With respect to the low-density polyethylene, the MFR and density fall within specified ranges. The invention also provides a composite film comprising a substrate film such as a crystalline polypropylene film and, laminated onto at least one side thereof, a resin layer of the above composition having a thickness of 2 to 200 &mgr;m. The above composition is excellent in laminate moldability and enables producing a composite film having excellent low-temperature sealing properties, blocking resistance and hot tack. The composite film is characterized by having excellent low-temperature sealing properties, blocking resistance, slip properties and hot tack.

摘要: A polyolefin synthetic pulp comprising a polyolefin resin graft-modified with an unsaturated carboxylic acid or a derivative thereof, and/or a polyolefin resin composition which comprises an ethylene/&agr;,&bgr;-unsaturated carboxylic acid copolymer and a polyethylene resin. Further, there is provided a heat sealing paper comprising a base fiber layer whose at least one surface is laminated and integrated with a layer of the polyolefin synthetic pulp. This polyolefin synthetic pulp has a large breaking length and an excellent internal bond strength, and exhibits stable heat sealing and hot tack properties over a wide temperature range from low to high temperature. The polyolefin synthetic pulp is suitable to use in battery separators, molding fiberboards, heat sealing papers and the like. The heat sealing papers have excellent heat sealing properties, and are characterized by having a large breaking length and an excellent internal bond strength and by exhibiting stable heat sealing and hot tack properties over a wide temperature range from low to high temperature.
