Document Type and Number:
Japanese Patent JP6657890
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a moisture permeable laminate excellent in an interlaminar adhesive strength and heat sealing suitability while having low basis weight and high moisture permeability.SOLUTION: There is provided a moisture permeable laminate in which a polyolefin-based resin nonwoven fabric I (A), a polyolefin-based resin porous film (B) and a thermoplastic resin nonwoven fabric II (C) are laminated in this order, where the laminate has a basis weight of 20-400 g/m, moisture vapor permeability of 1,000-20,000 g/(m24hr), a water pressure resistance of 100 kPa or more and an interlayer adhesive peeling strength between the polyolefin-based resin nonwoven fabric I (A) and the polyolefin-based resin porous film (B) of 0.5 N/15 mm or more.SELECTED DRAWING: None
