Shoppers are to be given a helping hand to reduce food waste thanks to Tesco’s new re-sealable salad bags. Salads are one of the UK’s most wasted foods by households, and figures* show that Brits throw away around 37,000 tonnes from their homes each year – the equivalent of 178 million bags of salad. The new bags have a sliding zip lock, similar to the ones used for family-sized cheese portions, to keep the salad from spilling out once it’s been opened. The packaging is made from a thicker film than usual to help protect the leaves from getting damaged.
