Plastic cover for pie racks

Does anyone know where I would find a durable plastic cover for a pie rack. The type that hold about fifteen pies & sit on a counter & not a full size speed rack. I tried a plastic sheet pan bag, but it’s not quite wide enough for our pies. I was hoping to find something more durable with a zipper. Thanks for your help

Talk to a tent and awning supplier or a custom boat top maker. They have a heavy plastic they use for the windows that would probably do the trick.
