The original tea bags were all simple cubes and single capsules. Put this type of tea bag into the water in the German diamond tea bag. The tea leaves will be concentrated in the tea bag and the brewing speed is very slow. However, due to the simple form, the machinery used for packaging is relatively simple, so it is still used by most businesses.
With the popularity of flower and fruit tea, ordinary tea bags can not accommodate the expansion of fruit particles and petals due to the small space, and diamond tea bags have appeared on the market.
As the name implies, the diamond tea bag is like a diamond, with a regular tetrahedral structure, and is packaged in food-grade nylon. The appearance of these tea bags is exquisite and clear, and the space inside the bag is large, which is conducive to the distribution of fragrance, and at the same time, it can also watch the changes in the shape of the tea, which is the mainstream trend of tea bags in the future. However, the processing cost of diamond tea bags is relatively high and few factories can produce them.
In addition, there are some special-shaped tea bags. Make some exaggerated adjustments based on the diamond tea bags. Despite their novel and interesting appearance, these tea bags are extremely complicated to process and are rarely used by brands.
