The packaging trademark of Yili milk is Tetra Pak, and he completely put the trademark on the side of the packaging. Consumers can completely distinguish between milk trademarks and milk box trademarks. The packaging box is mainly produced for sale, and the registered trademark is to enable consumers to identify the source of the product. But the packaging box is different from other commodities, and the trademark logo should not be marked in the most eye-catching position. It is best to publicize and highlight the trademark of the packaging box, otherwise it will be too eye-catching and the packaging box will not sell well.
