At present, the material replaced by Fenbao at one time is non-uniform joint, which will not produce harmful quality at high temperature. Now the new materials are Japanese nylon materials (popular triangle bags and three-dimensional bags), which are more fashionable when transparent and degradable, so they are very safe and can be used with care.
After soaking the tea bag for 2 to 3 minutes, the tea bag will be taken out. It is not recommended to soak tea bags in water for a long time, and it is not appropriate to drink tea bags overnight. Nowadays, many disposable tea bags are made of plant fibers and plastics, mainly including non-woven fabrics, nylon, corn fibers and filter paper.
Among these four categories, non-woven fabrics and nylon are plastic raw materials with low cost, strong toughness and high transparency, which make tea and scented tea sell well.
Development history of disposable teabags
/kloc-More than 0/00 years ago in the United States, there was a tea merchant named Thomas who racked his brains to expand sales every day, but tea is a special commodity because the taste and taste vary greatly from place to place. You can't judge the quality of tea just by its appearance. You need to taste tea to know the taste of tea and decide whether to buy it.
So many customers need to send samples for tasting every day. But it is not cost-effective to send more. After all, Qian Shan Wanshui was imported from the East, but the taste was too weak to be sent less and the quality of tea could not be completely tested. After thinking hard, Thomas put the tea into a silk bag, which is almost enough to make a cup of tea, so that customers can not only taste the quality of tea.
And will not cause excessive cost. However, in America at that time, many people drank tea. Thomas's original intention is to use silk woven bags as containers for people to take back tea leaves and pour them into cups for soaking, but many people don't know this. They throw silk woven bags and tea leaves into cups and brew them. Gradually, people found it very convenient to make tea in this way.
When drinking tea, you can drink tea directly without touching the tea leaves, and it is also very convenient to clean. Just pick up the silk bag and throw it away. 1903, Thomas applied for a patent for this tea bag he invented, and later this patent was selected as "100 1 Invention that changed the world". Thomas's invention is the predecessor of disposable tea bags.
