Abstract
To provide a cellulose acylate film, a food packaging material, an agricultural material, and a film for a polarizer, by which it is possible to improve folding endurance and biodegradability while maintaining transparency and moisture permeability.SOLUTION: A cellulose acylate film 11 is used as a food packaging material, an agricultural material, and a film for a polarizer. The cellulose acylate film 11 includes: a cellulose acylate whose acyl group substitution degree is in a range of 2.50-2.97, and a biodegradable polyester whose weight average molecular weight is in a range of 50000-1000000. The cellulose acylate film has a haze degree in a range of 5% or less.SELECTED DRAWING: Figure 1
