Blocking is the tendency of film surfaces to stick to one another; it can cause severe problems during film winding operations and final packaging applications. Incorporation of small quantities of GASIL® antiblocking silica into a film formulation confers a micro-rough surface to the film. This reduces or eliminates blocking without adversely affecting other film properties.
GASIL® antiblocking silicas are produced in many grades covering a wide range of properties so that the end user will be able to find the ideal product that balances antiblocking performance with excellent film processing, optical, and physical characteristics.
