Title:
LAYERED PRODUCT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/176524
Kind Code:
A9
Abstract:
Provide are: a layered product that is obtained by stacking a film on at least one surface of a sheet-shaped foam, and that satisfies requirements (A) to (E); and a method for manufacturing the layered product. (A) The foam has a thickness of 0.05-1.5 mm. (B) The film has a thickness of 25-250 μm. (C) The film has a surface resistivity of at least 1 × 1011 Ω. (D) The foam and the film are directly joined together without an adhesive therebetween. (E) The peel strength between the foam and the film is 10-100 mN/25 mm. With the present invention, a layered product can be provided that enables various kinds of processing to be preferably performed on a thin foam thereof without causing deformation of the foam, a film can be properly detached from the layered product, and the foam can be readily used alone. Furthermore, since the layered product is formed without an adhesive, it is possible to eliminate the possibility of any adhesive remaining on the foam after detachment of the film.
