Bottled joy:How to make a colorful one-gallon gradient sports bottle

The bright gradient color 1-gallon sports bottle is very popular and is inseparable from its unique structure. It consists of two coaxial arrangements. The outer wall of the inner cup is very artistic. When hot water is poured into the kettle, the shape of the inner cup will not affect the quality of your drinking water, and will not cause unhealthy and inappropriate adverse reactions. However, before making a sports bottle similar to this colorful style. The materials used in the sports bottle must be materials that meet the national food safety standards.

        How is the gradual kettle made?

        1. Direct printing

        Refers to printing directly on the cup with a reel printing machine. This technique is technically difficult. The general factory can only print one to three colors. If you meet the high requirements of setting the location, you can't use it, but a powerful factory can. It can print up to 20 colors without shifting gears. This technology is only suitable for small batch production, and the efficiency is very low. It is very difficult to print only color blocks and print photo effects.


        2. Water transfer

        Printing on water transfer paper with a printing machine can be printed in rich colors or mass-produced. However, the environment is relatively high. The printing environment requires constant temperature and humidity to ensure printing accuracy. Place the completed water transfer paper in water, separate the pattern from the paper, and transfer the pattern to the cup to bake the finished product. The following Christmas color change cup belongs to this process.

        3. Heat transfer

        The printing process is basically the same as the water transfer process, and the printing of the heat transfer paper is transferred to the cup through the heat and pressure of the machine. When using water transfer to produce color changing cups, all re-release modes require manual operation, and the machine automatically completes the heat transfer. Therefore, the modern color change cup factory has color pigment production lines, automatic printing production lines and automatic heat transfer stickers are the strongest reflection of competitiveness.
