The Definitive Guide to Dispenser Compatibility and Sustainable beverage BIB Packaging
Key Takeaways:
- Universal Compatibility: Fits Coca-Cola, Pepsi, and all major global dispenser systems.
- Efficiency: Dip Strip technology ensures <1% product waste.
- Sustainability: New PE+EVOH structures replace non-recyclable Nylon (PA).
- Capacity: Manufacturing in US, Europe, and Israel.
Post-mix beverage bags are precision-engineered Bag-in-Box (BIB) packaging solutions specifically designed for dispenser systems in global restaurants, convenience stores, and high-volume foodservice operations.
Since 2009, Aran has manufactured millions of these specialized bags annually, serving as a primary supplier for leading global brands including Coca-Cola, Pepsi, and Keurig Dr Pepper. Unlike standard BIB packaging used for ready-to-drink products, post-mix bags must meet rigorous technical requirements for connector compatibility and oxygen barrier protection for concentrated syrups and alcohol mixes.
Universal Connector Compatibility: Supporting Major Dispenser Infrastructure
In the post-mix ecosystem, connector compatibility is the most critical operational factor. Because major beverage manufacturers utilize proprietary dispenser systems, the bag’s valve must meet exact mechanical specifications to ensure a leak-proof, airtight connection. For instance, a bag designed for a Coca-Cola system is physically incompatible with Pepsi equipment without the correct proprietary fitment.
Aran streamlines supply chain complexity by manufacturing bags compatible with every major connector type used worldwide:
- Coca-Cola Connectors: Full compatibility with all generations of Coca-Cola dispensing equipment.
- Pepsi & Keurig Dr Pepper: Precision-molded valves for standard North American distribution systems.
- International Proprietary Systems: Specialized fitments for the unique dispenser requirements found in European and Asian markets.
- Universal Fitments: Multi-brand solutions for distributors managing diverse dispenser fleets.
By offering universal compatibility, Aran allows beverage brands to consolidate their packaging procurement under a single supplier, significantly reducing inventory complexity and logistics overhead.

Internal Dip Strip Technology: Maximizing Product Yield and ROI
A primary challenge in high-viscosity beverage dispensing is “bag collapse,” where the flexible film creases and traps residual product. To solve this, Aran developed the internal dip strip – a structured pathway molded directly into the bag’s interior during the manufacturing process.
How the Dip Strip Enhances Performance
The dip strip acts as a rigid channel that extends to the bottom of the bag. As the dispenser pump draws liquid, this channel prevents the film from sealing against itself, ensuring a continuous flow even as the bag reaches its final servings.
Key Technical Benefits:
- Maximum Yield (<1% Waste): Ensures virtually every drop of expensive concentrate is dispensed, providing critical cost management for foodservice operators.
- Consistent Flow Rate: Guarantees a steady pour from the first to the very last serving, maintaining beverage quality standards.
- Extended Equipment Life: Reduces the vacuum strain on dispenser pumps, preventing premature motor failure and maintenance costs.
- Viscosity Management: Particularly effective for thick syrups, mayonnaise-based sauces, and concentrated alcohol mixes that typically suffer from high residual waste.
Optimized Sizing for Global Foodservice Operations
Aran produces post-mix bags in three standardized sizes, all featuring the same high-barrier protection and dip strip technology.
| Bag Size | Typical Applications | Estimated Serving Yield |
| 5 Liter | Small operators, low-volume specialty drinks, and seasonal flavors. | ~25–30 Servings |
| 10 Liter | The industry standard for restaurants, convenience stores, and standard foodservice. | ~50–60 Servings |
| 20 Liter | High-volume environments: stadiums, large QSR chains, and cruise ships. | ~100–120 Servings |
Sustainability Leadership: Transitioning to Recyclable PE Structures
The beverage industry is currently undergoing a major shift in material science. While the traditional market standard has relied on PA (Nylon) multilayer structures for their oxygen barrier properties, these materials are difficult to recycle in standard waste streams.
Aran is pioneering the transition toward PE-based (Polyethylene) structures with integrated EVOH barrier layers:
- Full Recyclability: Designed for compatibility with existing PE recycling streams.
- Regulatory Readiness: Compliant with evolving European PPWR (Packaging and Packaging Waste Regulation) standards.
- Carbon Footprint Reduction: Lower emissions during the manufacturing process compared to traditional multi-material films.
- Performance Parity: Successful commercial trials with major beverage producers prove that PE+EVOH maintains shelf life (6–18 months) and product freshness identical to traditional PA structures.

Expanding Capacity: New Production in North America
To support the growing demand from North American beverage brands, Aran USA has invested in a state-of-the-art post-mix production line at its Greer, South Carolina facility.
This strategic expansion, expected to be online by Q3 2026, will:
- Double manufacturing capacity specifically for the North American post-mix segment.
- Drastically reduce lead times for U.S. and Canadian distributors.
- Facilitate rapid prototyping for custom connector designs and proprietary valve systems.

Frequently Asked Questions (FAQ)
What is the difference between post-mix bags and standard bag-in-box? Post-mix bags feature specialized valve fittings for dispenser connection, internal dip strips for maximum yield, and barrier structures optimized for concentrated syrups rather than ready-to-drink products.
Are Aran post-mix bags compatible with Coca-Cola dispensers? Yes, Aran manufactures bags with valves compatible with all Coca-Cola connector systems, including both current and legacy dispenser models.
Can post-mix bags be recycled? Aran’s advanced PE+EVOH structures can be recycled in polyethylene waste streams. Traditional PA structures have limited recyclability. Contact us for the latest sustainable material options.
What is the typical shelf life of the product? Aran’s high-barrier structures typically support 6–18 months of shelf life for most beverage concentrates. Specific validation should be conducted for each unique product formulation.
Does Aran support custom connector designs? Yes, Aran’s engineering team can develop custom valve solutions for proprietary dispenser systems. Contact us to discuss your specific requirements.
