Technical Characteristics
Hollow structure provides high rigidity while reducing shipping and handling costs.
High-impact PP copolymer prevents cracking during die-cutting and heavy-duty use.
100% waterproof and chemical resistant; suitable for humid or harsh environments.
Corona-treated surface (≥46–48 dyne/cm) improves ink adhesion for screen printing, UV printing, and lamination applications.
Controlled extrusion process ensures excellent flatness for automated processing.
Performance Selection Guide
Thickness Recommendation：
2–3 mm: Lightweight signage and printing boards
3–5 mm: Packaging inserts and reusable containers
5–8 mm: Industrial protection and structural use
8–10 mm: Heavy-duty applications
Final selection depends on load, usage frequency, and processing method.
Material Control
We use polypropylene raw materials with controlled batch sourcing to ensure stable physical performance and consistency across production runs.
Virgin PP and recycled PP grades are available depending on application requirements.
