Abstract:
An object of the invention is to provide a composite body with which a molded article having both excellent external appearance and excellent light-transmitting properties can be produced. The composite body of the invention is a composite body having an aluminum base material having a plurality of through-holes in the thickness direction; and a resin layer provided on at least one surface of the aluminum base material, in which the average opening diameter of the through-holes is 0.1 to 100 μm, and the average opening ratio provided by the through-holes is 1% to 50%.
Abstract:
Provided are a hygroscopic material having a transparent base material, a upper layer including a vinyl acetate resin, and a hygroscopic layer which is arranged between the base material and the upper layer to be adjacent to the upper layer and includes a moisture-absorbing agent which is an inorganic salt, and a resin, a method for producing the same, and a packaging material.
Abstract:
Provided is a moisture-absorbing material having, in the following order: a moisture-permeable polymer layer; a moisture-absorbing layer having a porous structure and containing amorphous silica with an average secondary particle diameter not exceeding 10 μm, a water-soluble resin and a moisture-absorbing agent; and a moisture-proof layer.
