Abstract
The tea bag paper comprises a first phase of natural fibers in a weight percentage of from 60% to 85%, and a second phase of heat-sealable synthetic fibers with the remainder of the weight percentage of from 15% to 40%. The second phase penetrates the first phase in such a way that both sides of the paper are adapted to be heat-sealed, with the unit area weight of the paper being between 10 and 15 g/m.sup.2. The tea bag paper exhibits enhanced tea diffusion, and may be processed on special high-speed automatic tea packing machines, because it is heat-sealable on either side thereof.
