Understanding Barrier Properties in Flexible Packaging

Barrier properties determine how well your packaging protects your product from external factors. Understanding these properties helps you choose the right packaging solution for maximum product freshness.

What Are Barrier Properties?

Barrier properties refer to how well flexible packaging resists the passage of gases, moisture, and light. These factors directly impact product shelf life and quality retention.

Key Barrier Metrics

OTR (Oxygen Transmission Rate): Measures oxygen passage. Critical for products like coffee, nuts, and oils. Our flat bottom bags feature high-barrier structures with aluminum foil options.

MVTR (Moisture Vapor Transmission Rate): Measures water vapor passage. Essential for dry products. Our vacuum seal bags provide superior moisture protection.

Common Barrier Materials

EVOH offers excellent oxygen barrier. Aluminum foil provides superior protection for sensitive products. Our barrier films combine multiple materials for optimal performance.
