Backing material is crucial because it prevents leaks and protects surfaces from moisture damage. The best backing material is one that is waterproof, durable, and resists shifting or bunching. Polypropylene backing, as found in products like Covidien Kendall 1038 Simplicity Extra, offers reliable leak protection, while PVC/polyester backing in Salk 1996 CareFor Deluxe Washable Underpad is both waterproof and nonslip. This variety allows users to select a pad that best matches their preferences for protection and stability, with several backing materials available across the product range.
