Protective liners are materials used to shield surfaces from damage, contamination, or wear. They are commonly made from various substances, including plastic, rubber, or foam, and can be found in applications such as industrial equipment, automotive interiors, and packaging. These liners help extend the lifespan of the underlying surfaces by providing a barrier against moisture, chemicals, and physical abrasion. In addition to their protective qualities, liners can also enhance safety by reducing slip hazards and improving grip. They are often customizable in terms of size and thickness, making them suitable for a wide range of environments, from construction sites to household use.
