Abstract

The teabag paper comprises a first phase of natural fibres in a proportion of 60 - 85 % by weight and a second phase of heat-sealable synthetic fibres in the remaining proportion of 15 - 40 % by weight. The second phase penetrates the first phase in such a manner that both sides of the paper are heat-sealable, the weight per unit area of the paper being between 10 and 15 g/m<2>. The teabag paper has improved tea diffusion and can be processed in special, fast, automatic tea packing machinery due to the heat-sealability on both sides.
