HARD RUBBER

Hard rubber is an essential material in die-making, specifically designed for thick corrugated cardboard (3–5 layers). With a standard hardness of 70 Shore A and high abrasion resistance, it helps widen crease lines, minimize paper cracking, and improve folding performance. This makes it an ideal solution for carton manufacturers aiming for stable quality, consistent output, and high efficiency in long-run production.

Product Overview

Hard rubber is designed to optimize creasing on thick corrugated boards, especially 5-layer grades such as AB and BC. Positioned adjacent to the creasing rule, it provides controlled compression, helping the crease line form cleanly and preventing cracking during folding.
Featuring strong resilience and long-term shape retention, hard rubber performs reliably in both flatbed and rotary die-cutting systems. It supports continuous, high-volume operations where consistent crease quality is essential for packaging performance.
