HC Deb 09 July 1941 vol 373 c178
59. Mr. Jackson

asked the Parliamentary Secretary to the Ministry of Food what are the reasons why the stamping of the retail price on tins of fruit and vegetables is considered impracticable by his Department?

Major Lloyd George

The stamping of can ends should be avoided as far as possible in order to avoid damage to the tin-plate, or, in the case of lacquer cans, to the internal coating of lacquer. Further, the sizes of cans have been standardised to a considerable extent and the same type of can may therefore be used as the container for more than one class of foodstuff. It is possible also that it will be necessary to change the price of a canned commodity between the time of embossing the cans and the date of sale.
