The supermarket pioneered the use of braille on packaging for selected medicines after two years of development in 2001. It then extended the labelling initiative to include its own-label alcohol.
Over the next few months, braille labelling will be introduced onto its chilled and ready meals, meat and poultry, bakery products, biscuits, desserts and pet food. The price of these products will not be affected.
The Co-op is signed up to the Guide Dogs for the Blind Association's high-street charter, which allows blind and partially sighted people greater independence while shopping.
The charter advises retailers on ways to assist the blind, such as explanations of store layout, store guides and help with packing shopping.
Co-op is to train its food staff on the new labelling and the Guide Dogs for the Blind charter, which is also being adopted by the company's high-street pharmacy business nationwide.
Separately, the supermarket has revealed that it is to double its own-label premium range to 25 products this week in line with similar expansion from rivals Tesco and Sainsbury's.
The Truly Irresistible sub-brand was created last year to help the Co-op's move upmarket from its image as a convenience retailer.
