Abstract:
1. A brim of a headwear, comprising a core made of a laminated shape-retainable sheet, comprising at least two shape-retainable sheets each comprising a mono-axially drawn olefin resin sheet having a total draw ratio of 10 to 40 and a thickness of from 0.1 to 0.5 mm, each having shape retainability in a monoaxial direction, and in which plural nicks or folds are made at intervals of 5 mm or less substantially parallel to the axial direction having the shape retainability, and at least one low melting point resin film made of (i) an ethylene/vinyl acetate copolymer or (ii) a linear low density polyethylene resin, wherein the low melting point resin film is laminated between the shape-retainable sheets by being heated under pressure and being bonded onto the shape-retainable sheets in such a manner that the monoaxial directions of adjacent shape-retainable sheets make a predetermined angle and do not have any space between the shape-retainable sheets.
