Introduction
High Oxygen Barrier BIB bags are essential for products sensitive to oxidation, which causes flavor degradation, color change, or nutritional loss (e.g., Vitamin C). Suzhou Jingle Packaging uses multiple barrier technologies, including EVOH and aluminum foil, integrated into multi-layer films. This structure ensures an ultra-low Oxygen Transmission Rate (OTR), significantly extending the ambient shelf life of oxygen-sensitive liquids.
Protecting the product from oxygen ingress is the primary function, crucial for maintaining quality and market value.
Specification
| Key Barrier Materials | EVOH (Ethylene-Vinyl Alcohol) or Aluminum Foil |
| OTR Rating | Measured in cc/m²/day (Typically below 1.0 for high barrier) |
| Shelf Life Target | Extended ambient shelf life (e.g., 6 to 18 months) |
| Fitment Design | Taps and glands designed to also minimize O₂ ingress during and after filling |
| Film Layers | Co-extruded structures up to 9 or more layers for maximum performance |
Logistics & Global Compatibility
International Standard: High barrier films are the industry standard for intercontinental shipping of high-value, sensitive liquid foods.
Audit Support: Provides detailed OTR test data and material certificates to satisfy global quality assurance audits.
Adaptable to Volume: Barrier technology is available across the entire volume spectrum, from 1L pouches to 1000L IBC liners.
Temperature Resilience: Barrier effectiveness is maintained across the typical range of temperatures encountered in global logistics.
FAQ
- Q: How is the OTR value tested?
- A: OTR is measured using specialized testing equipment (e.g., MOCON) in a controlled environment, providing a quantifiable rate of oxygen passage through the film.
- Q: Which is better, EVOH or Foil, for oxygen barrier?
- A: Foil generally provides a near-zero barrier (best), but EVOH offers excellent barrier properties while maintaining transparency or translucency, suitable when light protection is not the primary need.
- Q: Do the fitments also have high oxygen barriers?
- A: Yes, fitments for high-barrier bags use specialized, dense resins and sealing gaskets to minimize O₂ ingress, as the tap/gland is the most vulnerable point.
