Lakeland Perforated Microwave Cling Film 5 "Brilliant idea" Mrs May 15 July 2019 I have never seen this product anywhere else, it works fantastically well. I use it for soups gravy or veg in the microwave and it's great not to have exploding clingfilm followed by a fountain of tomato soup or whatever. The pressure of the steam is let out through tiny holes, genious! It also works well for everyday wrapping of food. If I have a jug of gravy or whatever which I want to keep for the next day I use this cling film to cover it and can pop it straight back in the microwave to reheat.
