Abstract
The disclosed stack carries individual sheets arranged one on top of the other for individual removal of each successive sheet from the stack. Holding the stack together are individual substrates with an adhesive portion. The adhesive portion on a substrate partially secures to a sheet and partially secures to an underlying substrate on alternating ends of the stack. Therefore, the free end of the sheet can be easily pulled free from the stack, exposing a free end of the next underlying sheet to be easily pulled free from the stack.
