Principles of Silica Antiblocking Agents
Differing manufacturing processes result in varying degrees of internal porosity. The higher the porosity,the more efficient the antiblocking grade will be.Blocking is the adhesion or bonding of two surfaces of film that occurs after production and/or during prolonged storage. Layers of polymer film tend to stick together, which is undesirable for stacked packaging and film processing& converting. Fast and damage-free unrolling of film is important. This “blocking” phenomenon is especially severe with polypropylene, polyethylene, and polyester films.
The funcitons of silica products for anti-blocking:
• Imparts a micro-rough surface to the film, resulting in less film-to-film layer contact
• Reduce blocking between the individual layers of film
• Has an extensive product portfolio to include tailor- made products for different film thicknesses and polymer types
