Custom tube packaging is very popular and has a wide range of applications. Many products use square boxes, but they are slowly being replaced with paper tubes, such as sleep eye blanket packaging. The sleep eye blanket adopts the simplest paper tube method. The inner tube and the outer tube (as a long cover) are two parts. It is a simple design, but when customers open the package, there will be more fun. When the cover is slowly pulled upwards, the unique printed content can be slowly displayed to consumers, which is a very interesting thing. Since both the inner and outer tubes can be printed, there is more space to display more information to customers, which is very helpful for customers to understand products and brands.
