High-Barrier COEX Technology
What is a COEX bottle?
Specialized barrier bottles manufactured through "co-extrusion". This process combines different plastic materials to provide the strength necessary to contain aggressive chemicals (e.g., pesticides) that would otherwise deteriorate or deform standard packaging.
Features & Benefits:
- Secure Packaging: Ideal for pesticides and agricultural chemicals.
- Ultimate Chemical Resistance: Withstands aggressive solvents, acids, and alkalis (pH 1-14) – perfect for glyphosate, herbicides, and liquid fertilizers.
- Superior Barrier Performance: EVOH layer reduces oxygen transmission to <0.1 cc/m²/day (vs. 2-5 cc for standard HDPE).
- Extended Shelf Life: Effectively extends product shelf life by 18+ months.
Advanced Layer Structure
1. Outer Layer: High-density polyethylene (HDPE) provides strength, durability, and moisture protection.
2. Tie Layer: Adhesive layer binding the outer and inner barrier materials.
3. Barrier Layer: The inner EVOH layer protects contents from oxygen and resists aggressive chemical deterioration.
Sealing: 6 layers of composite gasket combined with electromagnetic induction sealing ensures a completely leak-proof effect.
