ANTIBLOCK CONCENTRATES
Antiblock concentrates incorporate inorganic components that microscopically "roughen" the surface of blown and cast films. These roughened surfaces minimize the surface contact area between the films and decrease the tendency of these surfaces to adhere to one another. Common antiblock agents are outlined below.
Common Antiblock Agents
- SILICA: Most Effective, Highest Cost
- TALC: Moderate Effectiveness; Best Clarity
- CALCIUM CARBONATE: Moderate Effectiveness; Lowest Cost
