2. Product structure:

Structure of a 3-layer carton box:

Surface layer: The outer layer of paper, usually white, yellow, or brown, is typically smooth and even.
Middle layer: This layer consists of corrugated paper layers with grooves that are glued to the surface and bottom layers, providing cushioning for the carton.
Bottom layer: It can be a regular paper layer or a hard paper layer to provide additional support.

The quality and texture of each carton sheet are specifically designed based on the application. The surface paper can be white, brown, or yellow. There are four main types of waves that form the grooves in the carton paper, namely Wave A, B wave, C wave, and E wave.

3. Application:

3-layer carton boxes are commonly used for light and low-cost items. They are suitable for packaging lightweight and rigid products such as plant protection products, noodles, paper towels, and more.
