I'm also not a big fan of the polyvinyl chloride (PVC) business. Rigid PVC, used for things like water pipe, is brittle and prone to fracture. The PVC water line between the street and my house fractured several years ago, as did the lines of all of my neighbors. Flexible PVC, which is used for such things as food wrap, contains about 40% "plasticizer," which are oils used to make the plastic flexible, and which often are toxic. These oils can leach into fatty foods. My recommendation: use polyethylene, which is cleaner, for food wrap. Anyway, I prefer companies that make good quality products, which PVC is not so much. It is one of the products that gives plastics, which was my field of work for many years, a bad name. (There are some high quality plastics.)
