Waitrose said the flow-wrap packs were lightweight but robust enough to withstand other items being placed on top of them in a shopping basket.
Meat buyer Andy Boulton said the new packs were a response to consumer demand for a practical way to cut waste.
"These packs are more slim-line that gives more room in shopping bags, fridges and freezers. With the added benefit of cutting waste by half at no extra cost, I predict that this style of packaging will be a real hit," said Boulton.
"Feedback from customers has already been really positive as they can still buy the same quality meat products but will be minimising waste."
