Title:
SHEET FOR FORMING AND SIMULTANEOUSLY LAMINATING, AND MANUFACTURE OF MOLDED AND SIMULTANEOUSLY SHEET- LAMINATED RESIN MOLDED ARTICLE
Document Type and Number:
Japanese Patent JP2000141398
Kind Code:
A
Abstract:

To prevent a breakage in injection molding by using a polypropylene having excellent surface strength and light resistance for a base material film.

The sheet 3 for molding and simultaneously laminating has 23 gf or above of a tensile break load when a test piece of the sheet for molding and simultaneously laminating of 10 mm of a width is fixed at a distance of 5 mm between a pair of chucks by using the chucks, one end of the piece is applied by a load at a predetermined speed of 500 mm/min at an environmental temperature of 62 to 94°C and a tensile test is executed. A base material film 1 of the sheet 3 is made of a single layer film of a transparent low crystalline operation polypropylene film. A pencil hardness value of the method of measuring according to JIS K 5400 at an opposite surface to a surface of the side to be adhered to a molding resin 10 of the film 1 is 3B to B of hardness. At least one or above of additives selected from an ultraviolet absorbent, light stabilizer and ultraviolet screening agent are contained so that a haze value of a molding resin 11 of the film 1 of the method of measuring according to JIS K 7105 becomes 2 to 30%.
