## FAQ

**1. Can samples be provided for testing?** Yes. We can provide samples for testing stiffness, cutting performance, and die-cutting compatibility.

**2. Is customized specification available?** Yes. We offer customized solutions in thickness, size, and basis weight.

**3. How is bonding applied in puzzle production?** A lamination process is typically used to bond the printed sheet to the puzzle backing paperboard, ensuring stable structure and consistent die-cutting performance.

**4. Should lamination be applied on the front or back side of the puzzle?** In standard production, lamination is applied on the back side of the printed sheet to preserve image quality on the front while ensuring strong adhesion to the backing board.

**5. Which is more suitable for production, a puzzle mat or puzzle paperboard?** Rigid puzzle backing paperboard is preferred due to its higher dimensional stability, better die-cutting precision, and consistent performance in high-speed production processes.

**6. Is the material environmentally friendly?** Yes. It is made from responsibly sourced virgin wood pulp from sustainable forestry.
