The major fear of any customer that orders pizza for delivery is that it will show up later than expected, and cold. To combat cold pizza, there are special insulated delivery bags that can keep pizza hot and fresh for up to 45 minutes. Pizza delivery bags do not produce an air tight seal. If they did, your pizza would show up warm and soggy, not hot and steamy. With a thin layer of foam insulation and a Velcro flap, our pizza delivery bags allow just enough steam out to maintain proper moisture and temperature. The venting also allows the mouth watering aroma escape, so the customer knows their pizza has arrived as soon as they reach the front door. Most pizza boxes are about two inches thick. You will want to check out the overall height of the delivery bag you choose to get an idea of how many boxes you each bag will carry. Some are 12 inches or more tall and are ideal for delivering several pizzas to a single location.
