Abstract

A light-shielding cloth that is to be bonded to a slit-form opening of a container for a photosensitive material is formed from a base fabric and a crimped pile thread incorporated into the base fabric so that the pile density is in the range from 45,000 threads/cm.sup.2 to 85,000 threads/cm.sup.2, a hot-melt adhesive region being provided on the reverse side of the base fabric without a filling agent being applied thereto for the purpose of preventing the hot-melt adhesive from penetrating the base fabric. A container for a photosensitive material is formed by bonding the light-shielding cloth to a slit-form opening using a 100% solids adhesive, preferably an ethylene-vinyl acetate copolymer resin based adhesive, without a treatment with a filling agent. A narrow-width light-shielding ribbon is formed by slitting the light-shielding cloth by means of an ultrasonic slitter.
