EU Enterprises: Large-Scale Application of Adhesive-Free Forming Technology, Promoting Full-Cycle Upgrade of Paper Shelv

Core Technological Innovation: In response to the mandatory requirements for recyclability in the EU's Packaging and Packaging Waste Regulation (PPWR), leading European paper product enterprises have realized large-scale mass production of adhesive-free forming technology, completely replacing traditional water-based or solvent-based adhesives. By optimizing the cutting angle of corrugated cardboard and folding buckle structure, each part of the paper shelf is fixed through mechanical engagement, reducing VOC emissions by 100% compared with traditional processes, and the recyclability rate is increased to 85%, which is 25 percentage points higher than the industry average.

A supporting bio-based coating material has been developed, balancing water resistance and degradability, which can maintain structural integrity for more than 6 months in a normal temperature and humid environment. It is also compatible with flexographic printing technology to ensure that the brand color reproduction is not limited by the process.
