A composite protective layer (also known as the outermost layer or waterproof layer) is not laid down for subsequent printing of foamed ink on the print layer. The printing layer carries the colors, patterns, characters, etc. required by the packaging material, and the foaming ink is also set on the printing layer. As for the compounding steps of the heat-sealing layer, the first bonding layer, the aluminum foil and the second bonding layer, it can be before printing or after compounding the protective layer, preferably after printing and before compounding the protective layer.

According to the type of material, microsphere foaming ink or groove bottom foaming ink can be used.

The foaming ink can be printed at a predetermined position on the printing layer, for example, when the packaging box is formed, the foaming ink area is located at the upper right corner of the front of the packaging box.

The protective layer is made of polyethylene (PE) or polypropylene (PP), which can protect, isolate and waterproof the packaging material.

Step 3) can be carried out during the manufacturing process of the packaging material, so that the finished packaging material has a convex and concave 3D pattern, such as a 3D trademark and a 3D identification code.

Step 3) is usually carried out after the beverage is filled. At this time, the packaging box has been formed. Immediately make a 3D pattern on the outside of the packaging box, such as a 3D identification code. In step 3), for heat-sensitive foaming ink, you can use hot air to heat the predetermined pattern.

For photosensitive foaming inks, a laser can be used to irradiate a predetermined pattern, such as a UV laser.
