Introduction

EVOH Barrier BIB Bags are a modern, high-performance solution utilizing Ethylene-Vinyl Alcohol (EVOH) polymer, known for its outstanding oxygen blocking properties. Suzhou Jingle Packaging uses EVOH as a core layer in multi-layer co-extruded films. EVOH offers an oxygen barrier significantly superior to standard PE films, approaching that of foil but providing the advantage of transparency or translucency, and often at a lower material cost than foil.

This material is ideal for products requiring a high O₂ barrier but not necessarily total light block.

Specification

Barrier Material	Ethylene-Vinyl Alcohol (EVOH)
OTR Rating	Low, typically in the range of 0.5 to 5 cc/m²/day (Depending on EVOH thickness)
Clarity	Transparent or translucent (Allows for visual inspection, if required)
Film Structure	PE/Adhesive/EVOH/Adhesive/PE (Common 5-layer co-extrusion)
Aseptic Option	Available with sterilization compatibility for aseptic filling

Logistics & Global Compatibility

Industry Standard: The most common barrier film used in the global wine and cold-fill beverage BIB industry.
Logistics Savings: Enables ambient transport for many products, reducing reliance on expensive refrigerated shipping.
Regulatory Acceptance: EVOH polymers are widely approved for food contact in all major international markets (FDA, EU).
Dimensional Stability: Film retains its shape and integrity, crucial for automated high-speed filling lines.

FAQ

Q: Is EVOH sensitive to humidity?
A: EVOH's barrier performance can decrease in high humidity. However, the multi-layer structure encases the EVOH layer with moisture-resistant PE, mitigating this effect for most BIB applications.

Q: Can EVOH bags be used for hot filling?
A: Yes, EVOH films are compatible with standard hot-fill temperatures (up to 85掳C), provided the outer and inner PE layers are appropriately specified.

Q: Are EVOH bags considered recyclable?
A: As a multi-material plastic, EVOH bags are generally not compatible with mono-material PE recycling streams and are often classified as non-recyclable in current recycling infrastructures.

Advantages

Excellent Oxygen Barrier: Provides substantial shelf life extension for oxygen-sensitive foods, rivaling foil for many applications.
Cost-Performance Balance: Offers a high barrier at a lower material cost than comparable foil laminates.
Visual Quality: Translucent film allows for visual confirmation of product fill level and quality checks before final sealing.
Processing Ease: EVOH co-extruded films often seal easier and more reliably than complex foil laminates.

Application

Wine and Beverages: Standard BIB wine and cocktail packaging for retail and food service.
Oxygen-Sensitive Juices: Concentrates and ready-to-drink juices where flavor preservation is key.
Liquid Food Ingredients: Non-aseptic, chilled bulk ingredients requiring extended O₂ protection.
Dairy Bases: Products requiring good O₂ control within the cold chain.
