Common Causes of Film Blocking in Plastic Film Manufacturing
Film blocking occurs when layers of plastic film stick together, creating challenges during unwinding, handling, and downstream processing. This issue can reduce productivity, increase waste, and affect product quality.
Common Causes of Film Blocking
• High film surface tack → Layers adhere together
• Excessive storage pressure → Increased contact between films
• Elevated temperatures → Softened film surfaces
• Insufficient anti-block additives → Poor film separation
• High slip additive migration → Surface interaction changes
Based on industry experience at Fluorence B N Mehra & Co., proper anti-blocking additive selection can help improve film handling, processing efficiency, and overall product performance in packaging, agricultural, and industrial film applications.
