PA/EVOH/PA Co-extruded Film

1. Ultimate Odor Barrier: Molecular-Level Lockdown
The film integrates a high-purity EVOH core barrier layer, rigorously locking in ammonia, hydrogen sulfide, and various organic volatile odor molecules. Whether for extreme odor environments or high-demand scent protection, it ensures zero permeation, maintaining long-term air purification in the surrounding area.

2. Peak Oxygen Barrier: Preventing Oxidation and Decay
Through the synergy of the symmetrical PA/EVOH/PA structure, this film provides an ultra-low Oxygen Transmission Rate (OTR). By blocking oxygen ingress, it effectively inhibits aerobic microbial growth and prevents oxidative discoloration or spoilage, significantly extending shelf life and freshness.

3. Superior Moisture Barrier: Precise Humidity and Damp Protection
The double-sided PE (Polyethylene) outer layers form a robust water barrier, effectively resisting water vapor permeation. This superior moisture protection prevents contents from clumping or spoiling due to dampness and ensures the high-barrier core remains stable even in high-humidity environments.

4. Full-Spectrum Protection: Ensuring Purity and Safety
The 7-layer precision co-extrusion structure integrates three major barrier functions into one, creating a highly stable sealed environment. While providing physical protection, the robust material ensures the integrity of the barrier layers, making it a reliable choice for the most demanding isolation needs.
