Opaque and pearlescent laminated and stretched products and method for making them

摘要

An opaque and pearlescent, laminated and stretched product comprises a layer (A) and a layer (B) overlaid on and laminated by melt-adhesion to at least one side of the layer (A). The layer (A) forms a uniform layer comprising 97 to 70 % by weight of a crystalline polypropylene and 3 to 30 % by weight of a cyclopentadiene type petroleum resin having a softening point of 160 DEG C or higher and stretched in at least one direction. The layer (B) comprising a crystalline polypropylene whose crystalline melting point is higher or lower than that of the crystalline polypropylene forming the layer (A) by less than 10 DEG C.
