1 Have you ever seen a plastic thermal transfer color-changing cup?
In 2008, "Love Call Transfer 2" became popular. The film was funny and touching. One of the products was impressive, which was one of the 365 touching moments that Leo Ku gave to Karena Lam - a black ceramic color-changing cup; in "If You Are the One", the male guest Guan Wei successfully held hands with Little Dragon Girl Jiang Long because of this black color-changing cup...

These are all ceramic thermal transfer color-changing cups. Nowadays, this kind of ceramic color-changing cup can be seen everywhere, but have you ever seen a plastic thermal transfer color-changing cup? Is it toxic? Let's find out...

Have you ever seen a plastic thermal transfer color-changing cup?

2 Is the thermal transfer color-changing cup toxic?
Some customers' thermal transfer color-changing cups need to be exported to Europe and the United States, so the product requirements are relatively high. The injection molding materials, alloy materials, thermal transfer materials, etc. of the products are required to provide relevant test reports to ensure that the products meet the standards for export to European and American countries.

Some customers’ sales targets are in China, and their requirements for thermal transfer plastic color-changing cups are relatively low. This situation has prompted thermal transfer color-changing cup manufacturers to have greater flexibility in choosing raw materials. They are faced with multiple choices in terms of plastic cup materials, PET bottom film, printing release agent, ink, thermochromic material, glue, diluent, etc., so whether it is toxic or not depends on your personal choice!

Different customers have different quality requirements for thermal transfer color-changing cups, and their prices are also different.

3. The production process of thermal transfer color-changing mugs
The production process of thermal transfer color-changing mugs is similar to that of other products. It is necessary to make thermal transfer color-changing flower films first, and then transfer the patterns to the products by heating and pressurizing them through a thermal transfer machine. The following is the production process of thermal transfer color-changing flower films:

1. First, apply PET film (apply release agent) according to the process of the thermal transfer color-changing flower films to be made;

2. Print the flower film pattern (printing process);

3. Apply the corresponding glue to the printed thermal transfer color-changing flower films (glue coating process);

4. Re-inspect the thermal transfer color-changing flower films coated with glue to ensure quality (re-inspection process);

5. Divide the thermal transfer film into strips (stripping process);

6. Package the stripped thermal transfer films (packaging process).

4.ULIKE thermal transfer color-changing mugs: strictly adhere to the quality link
ULIKE has been engaged in the thermal transfer industry for more than ten years and has been strictly guarding the quality link. The raw materials used meet European and American standards. The temperature-sensitive material used in the Hongda brand thermal transfer color-changing mug is printed on the cup body. The material used is imported high-quality heat-sensitive material, which can withstand high temperatures of 320 degrees Celsius, is non-toxic, lead-free, and chromium-free, and can meet the European food FDA standards. At the same time, the heat-sensitive material is completely isolated from the outside of the cup, does not come into contact with the beverage in the cup, and will not cause pollution.
