Abstract
An end cap support for the protruding end of a jumbo roll of paper or other materials (weighing between 2,000 and 4,000 pounds) includes at least one corrugated paper panel bonded to at least one lightweight rigid panel, preferably comprising luaun wood that resists moisture absorption. A very substantial weight reduction is obtained consonant with excellent stacking strength for the end cap support. The luaun panel does not fold over or warp, and all of the materials are biodegradable and hence environmentally friendly.
