Silicone Base Paper: The Backbone of Release Liner Technology
Silicone base paper, also known as release base paper, is a specially engineered paper substrate that serves as the foundational layer for silicone-coated release liners. This material plays a vital role in a wide range of industrial and consumer applications, where non-stick surfaces, controlled adhesion, and clean release are essential.
From pressure-sensitive labels and self-adhesive tapes to medical dressings and industrial laminates, silicone base paper forms the unseen yet critical support layer that ensures reliable product performance and user convenience.
What Is Silicone Base Paper?
Silicone base paper is typically made from super-calendered kraft paper (SCK), glassine, or poly-coated paper, engineered to exhibit high dimensional stability, smoothness, and strength. The base paper is coated with a thin layer of silicone — often cured via thermal or UV processes — creating a low-surface-energy surface that enables easy release of adhesives and sticky materials.
Key Characteristics
High smoothness for uniform silicone coating
Tensile strength to withstand machine processing
Moisture resistance and dimensional stability
Compatibility with silicone curing technologies (thermal, UV)
Customizability in terms of release force, color, and printability
