Teabag is the most popular way of drinking tea in the world. Although the history is not long, it develops rapidly. The current sales volume has accounted for about 50% of the world's tea trade volume. Tea in bag is the most popular in developed countries in Europe and America. According to reports, more than 80% of the tea in Canada, Italy, Holland, France and other countries is consumed in the form of tea in bag, and the United Kingdom and the United States have also reached about 80%. However, due to the late development of Chinese teabags and the influence of traditional tea drinking habits, the consumption of teabags in China only accounts for about 2% of the total sales of tea. With the improvement of people's living standards and the diversification of consumption forms, teabags are gradually favored by more and more people because of their quantitative, hygienic, convenient and fast characteristics.
Tea filter paper is the most basic packaging material for teabags. According to the different sealing forms, it can be divided into heat-seal tea bag filter paper and non-heat-seal tea bag filter paper. Heat-seal tea filter paper is mainly composed of one or more of polypropylene fiber, PET fiber, nylon and plant fiber. In recent years, some companies have also used corn fiber to prepare heat-seal tea bag filter paper. Non-heat-seal tea bag filter paper is mainly made of hemp pulp or hemp pulp and wood pulp. Because its raw material is completely made of plant fiber, it has soft and uniform paper quality, high dry and wet strength, fast water filtration speed, non-toxic, no peculiar smell, and can be used as a filter paper. Biodegradable, it is a green environmental protection product that meets food hygiene standards. At present, the international market is mainly dominated by non-heat-seal tea bag filter paper.
