It is used to protect other packaged products from damage. Multi-layer corrugated paper, also known as corrugated board, is a multi-layer adhesive body. It consists of at least one layer of corrugated core paper interlayer and two layers of surface paper. In the production process of multi-layer corrugated paper, the corrugated core paper interlayer needs to be bonded to the surface paper with professional glue. In order to make the corrugated core paper interlayer and the surface paper firmly bonded, professional pressing devices are required for pressing.
