The major food retailers including Tesco, Sainsbury's and Marks and Spencer have all agreed to cut the carbon footprint of grocery packaging by 10 per cent over the next two years.
This will mean selling milk in bags, spirits in plastic bottles, meat in vacuum-packed plastic bags and loose fruit and vegetables. Even Easter eggs will come with less plastic packaging.
The agreement, that was driven by groups like the Women's Institute, will encourage retailers to provide facilities to recycle wrappings for bread and grapes as well as plastic bags.
To help consumers cut food waste, supermarkets will sell smaller portions such as half loaves of bread and suggest recipes for left overs.
The Department for the Environment, Food and Rural Affairs, that drew up the agreement, said it could save consumers £800 million over three years because of the reduction in the amount of food thrown away.
