Product Definition and Core Features
Suofeng Blister Whiteboard Paper is a multi-layer composite board specifically designed for blister forming processes. It combines a sophisticated structure with eco-friendly coating technology to deliver exceptional stiffness, superior blister adhesion, and excellent printability. Key attributes include:
High Stiffness & Shape Retention: With a basis weight range of 250–450 g/m² and transverse stiffness ≥55 mN·m, it ensures structural stability during blister forming and long-term use, ideal for complex packaging designs.
Optimized Blister Compatibility: Its micro-porous coating structure-enriched with micron-sized calcium carbonate particles-facilitates uniform penetration of water-based blister adhesives. This design ensures the failure interface occurs within the paper layer during peeling, achieving a success rate exceeding 95%.
Printing Excellence: Boasting a brightness of ≥85% ISO, surface smoothness (Bekk) ≥800 seconds, and ink absorption of 22–25%, it supports high-definition color printing and intricate graphic reproduction.
Eco-Certifications: Manufactured with FSC-certified wood pulp and chlorine-free bleaching, it complies with EU RoHS standards, ensuring sustainability and safety for food and pharmaceutical applications.
2. Technological Innovations & Manufacturing Process
Songhong Industrial operates a state-of-the-art 21,000 m² production facility, integrating 智能化 systems and advanced equipment to ensure precision andMulti-Layer Composite Structure:
Top Layer: Bleached chemical wood pulp (LBKP + DMOW) for enhanced brightness and surface strength.
Core Layer: Recycled pulp blended with wood flour to reduce delamination and optimize blister adhesion.
Bottom Layer: De-inked recycled pulp for anti-curling properties and dimensional stability.
