Booker has rolled out a range of 100 Polish products into 52 of its depots.
The lines include pickles, ready meals, confectionery and snacks, as well as Polish beers and vodka.
The depots selected to sell the range are in areas where research has shown the products are most popular. Retailers will also be able to order in products where their branch does not stock the range.
Director of retail Steve Fox said: "There has not been a better time to introduce the range. We are offering some of Poland's most popular brands."
