Erucamide is a long-chain fatty acid amide widely used as a slip and anti-block additive in polyolefin and other thermoplastic films. It migrates to the film surface during processing, reducing friction between layers and preventing sticking. Erucamide is known for its long-lasting slip effect and excellent heat resistance, especially in BOPP, PE, and PP packaging films.

Q1: Is Erucamide food contact approved?
Yes, food-grade versions are available and comply with FDA and EU standards.
Q2: What is the typical dosage?
Normally used at 0.1 – 1.0 phr depending on film thickness and processing conditions.
Q3: Will it affect printability or heat sealing?
Erucamide has minimal impact on print or seal when used correctly.
