Why Use a Liner in the First Place?
Automotive fluid packaging once had to adhere to available materials. For instance, engine oil once came packaged in either heavy glass bottles or metal cans. The bottles added to transportation costs and increased the chances of lost fluids from breakage. Cans proved difficult for consumers to use without a special opener and spout. Cardboard containers overtook the metal cans but still presented difficulties in reusing the container for storing used oil.
During the 1980s, a shift in packaging materials allowed automotive fluid manufacturers to take advantage of lightweight plastic. It had a lower weight that made cardboard a desirable material and the reusability of glass containers. Polyethylene bottles, though, are not as easily recycled as cardboard, metal, or glass.
A solution to the issue of shipping and storing automotive fluids today comes in the form of drum and pail liners. These flexible bags line the interior of larger, rigid containers, allowing the repeated reuse of the outer container. Unlike pouches, which also appeared around this time, drum liners have a rigid supporting container around the interior liner. Using rigid containers improves the safety of the contents of the liner.
Additionally, drum and pail liners allow for easier bulk packaging while reducing overall container weight. Lower container weights reduce shipping costs due to less fuel needed for transporting the lighter shipment.
