PURPOSE:To inhibit the generation of paper powder by forming a cavity- containing oriented molding layer, in which specific quantities of specific high softening-point petroleum resin and inorganic fillers are compounded with a crystalline polypropylene resin, into an oriented molding layer composed of the crystalline polypropylene resin. CONSTITUTION:A laminate in which a cavity-containing oriented molding layer consisting of a composition, with which a 1-100 pts. wt. substance having the softening point of 160-230 deg.C in a cyclopentadiene petroleum resin and 0.5-200 pts. wt. inorganic fillers are compounded to 100 pts. wt. the same or different crystalline polypropylene resin, is formed into at least one surface of a layer made up of an oriented molding mainly comprising the crystalline polypropylene resin is employed, and a transparent laminated oriented molding having total light transmittance of 30% or less is used. |
