    摘要： A food packaging method is provided in which food is packaged in a package with use of carbon dioxide to benefit from bacteriostatic effects and the food package contains the minimum reduced gas spaces and thereby has a volume substantially equal to the food volume. Tightly-fitting food packages are obtained by the method. A tightly-fitting food package is obtained by: placing at least one kind of foods selected from the group consisting of meats and processed meats in a plastic film package; blowing a carbon dioxide gas in the package to fill the package with the carbon dioxide gas in a volume of 10 to 45 cm3 per 100 g of the food as measured at 0° C. and 1 atm; and sealing and refrigerating the package.

    摘要： An inorganic thin film polarizer having polarization characteristics comprises: a matrix for thin film polarizer composed of fine columns thereof arranged on a substrate; and light absorbing portions provided on the columns. The columns are made of inorganic substance which is transparent in the desired wavelength region of light such as the visible light region, ultraviolet region and infrared region, and each column has a substantially circular cross section. The columns are tilted at a constant angle with respect to a surface normal of the substrate and has anisotropy in density. The light absorbing portions have a light extinction coefficient larger than that of the columns at the desired wavelength region of light. The columns are arranged at a spacing of from 0.2 to 20 times the diameter of the column.
