PLA Heat Seal Film for Fruit & Vegetable Packaging Breathable 15-30μm
This PLA heat seal film is designed for packaging fresh produce such as vegetables and fruits. Made from corn-based polylactic acid (PLA) through multi-layer co-extrusion and biaxial orientation. The film offers good breathability and anti-fog effect, helping release excess moisture, reduce condensation, slow respiration, and maintain freshness. It complies with EU 10/2011 for food contact. Suitable for bags or lamination of lettuce, spinach, broccoli, strawberries, blueberries, cut fruit, and other produce. Thickness, width, and roll length can be customized.
