Cardboard boxes are widely used packaging products, available in various types depending on the materials used, such as corrugated boxes and single-layer cardboard boxes, with a range of sizes and models. What are the characteristics of cardboard boxes? Check out the introduction brought to you by the Yantai cardboard box manufacturer—
Corrugated boxes are commonly available in 3, 5, and less frequently in 7 layers. The layers include inner paper, corrugated paper, core paper, and outer paper. The inner and outer papers can be kraft paper or brown kraft paper, with the core paper being corrugated.
