Are there different types of liners?

There are many types of liners that perform different functions. Pressure-sensitive liners tend to work best with powder and dry products. Foam liners work well with liquids and products that could leak or spill. Heat induction liners and foil liners provide the best tamper evidence and freshness seal for both wet and dry products. Vented liners are used on products that may give off gas or expand and require a vent in the liner.
