Cardboard food trays are a mainstay of the food services industry. White cardboard trays are popular with patisseries, cake shops, takeaways and more. They come in straight walled varieties for cake shops, and also the angled wall boat shape for takeaways. They're commonly used to serve fish and chips, loaded fries and more in takeaways and are popular due to the extremely low cost per unit. Cake shops love cardboard trays too because of the variety of sizes that they're available in, and their low storage space requirements.
