Bottled joy: How is the gradient color one-gallon sports bottle made?

Gradient color 1 gallon sports water bottle is gorgeous in color because it cannot do without its unique structure. It consists of two coaxially arranged outer cups and inner cups. The outer wall of the inner cup has artistic style gradient colors. When hot water is poured into the gradient color sports bottle, the outer color of the inner cup will not affect the quality of your drinking water, which will cause unhealthy and unsuitable adverse reactions to the body. The production is similar to this style and the color is colorful. The material selected for the sports bottle must be made of a material that meets the national food safety standards.

The color of the gradient sports bottle is mainly due to this heat-sensitive coating structure. Because the heat-sensitive material is completely isolated in the inner layer of the cup, it will not touch the beverage in the cup. It is non-toxic, harmless, non-polluting, and can be used unlimited times.

1. Direct printing

Refers to printing directly on the cup with a roll printing machine. This technology is technically difficult. The average factory can only print one to three colors. If it encounters high requirements for the set position, there is nothing that can be done with more colors, but the powerful factory can. Overprinting up to 20 colors without shifting, this technology is only suitable for small batch production, and the efficiency is very low. Only color blocks can be printed, and it is very difficult to print photo effects.

2. Water transfer

It is printed on water transfer paper with a printing machine so that it can print rich colors, and it can also be mass-produced. However, the environmental requirements are relatively high. The printing environment requires constant temperature and humidity to ensure printing accuracy. The finished water transfer paper is placed in water, the pattern is separated from the paper, and the pattern is transferred to the cup to bake the finished product. The following Christmas color-changing cups belong to this kind of craft.

3. Thermal transfer

The printing process is basically the same as the water transfer printing process, the printed heat transfer paper is transferred to the cup body through the machine's heating and pressure. When water transfer printing is used to produce color-changing cups, all reposting patterns need to be manually operated by humans, while heat transfer is automated by machines. Therefore, a modern color-changing cup factory has a color-changing pigment production line, automatic printing production line and automatic heat transfer The printing decal production line is the strongest embodiment of competitive strength.
