Water transfer printing is another surface treatment technology used for thermos cups. This technique involves applying a design or pattern on the surface of the cup using a film transfer process. The design or pattern is first printed on a water-soluble film, which is then transferred to the surface of the cup using water. The result is a customized and durable finish.

Thermal transfer printing is another surface treatment technology used for thermos cups. This technique involves using heat to transfer a design or pattern from a paper or film onto the surface of the cup. The transferred design or pattern is permanent and resists fading, making it a durable and long-lasting finish.

Finally, 3D printing is another surface treatment technology used for thermos cups. This technique involves using a 3D printer to create a customized design or pattern on the surface of the cup. 3D printing allows for intricate and detailed designs to be applied to the surface of the cup, providing a unique and personalized finish.
