The food items which were wrapped in polythene film doesn't get rotten or decayed as polythene wrap consists of transparent and flexible thin film that hold together food items to form a tight seal. This film keeps the food items fresh by preventing it from air and also preventing dry food items from absorbing moisture and wet food items from losing its moisture. It also prevent the odors of food items for spreading to other food items that stored nearby.
