Sainsbury’s are launching new eco friendly milk bags and jugs as an alternative to plastic bottles. The move comes as they try to reduce the carbon footprint of milk consumption. They have partnered with Dairy Crest to launch the products which should soon be on sale. They will start by stocking a whole milk bag which will be followed by semi skimmed and skimmed milk bags next year. The new product contains 75% less plastic than the plastic bottles and they take up less space when disposed of. The product is also 6p cheaper to buy. There have been reports that some customers have found them difficult to use and have experienced leaks and spills but it will be interesting to see if people switch from plastic bottles. Tesco are also planning to launch a similar product in their stores.
