Coasters can be divided into the following types based on their material:

1. Paper coasters are usually disposable and cannot be cleaned with water due to their fragile nature;
2. Wooden coasters have strong practicality and durability, but their colors and types are too monotonous;
3. Plastic coasters are made of PVC plastic, with a variety of shapes, such as cartoon, brand, simulation models, etc. The addition of company and enterprise logos is more prominent, which not only has practicality, but also can achieve good visual and advertising effects. In addition, coasters made of PP material, as well as coasters with a combination of PP top and EVA bottom, are also popular abroad.
4. Metal coasters are mainly made of tinplate, which is also lightweight and durable.
5. The flower coaster captures the blooming flowers in nature, undergoes sorting and processing, and uses special tools to dehydrate them to maintain their original colors. It is then conceptualized, designed, and pasted by the author to create a new shape, giving it new life.
6. As long as the silicone coaster uses food grade silicone, it is harmless, safe, and non-toxic to the human body, making it useful for the "multi color integrated molding process" to achieve a more colorful appearance. It is one of the most popular advertising promotional gifts.
