Tea bag filter paper
Tea bag filter paper (teabagpaper) is a kind of special packaging paper with low basis weight. It is used for the packaging of tea bags. It requires uniform fiber structure, no wrinkles, no peculiar smell, large wet strength and a certain filtering speed, water-resistant foam, and It should be adapted to the drying strength and elasticity of the tea bag automatic packaging machine.
The non-heat-sealing type is usually made of whole wood pulp, using a mixture of paper pulp and manila hemp pulp. Heat-sealing paper contains low-melting fiber such as polypropylene fiber and ES fiber.
Foreign countries produce more tea bag filter paper than Manila hemp. In our country, mulberry fiber is made by beating with high degree of freedom after resin treatment, and synthetic fiber (ie wet-laid non-woven fabric) can also be used.
