Between May 7–13, 2026, the global packaging and processing industry gathers in Düsseldorf for Interpack 2026. For companies operating in food production, processing, and supply chains, Interpack remains the most concentrated snapshot of where the industry is heading.
This year, Aran Group will exhibit alongside WERIT at Hall 10, Booth D40, in a joint stand spanning 189 square meters. The dedicated Aran area is designed to host meetings and present key technologies in flexible liquid packaging – with a particular focus on bulk formats and the operational challenges they address.
Bulk Packaging: Where the Conversation Is Moving
Within the joint stand, Aran’s primary focus will be on bulk liquid packaging solutions – an area where demand continues to grow across global food manufacturing and ingredient supply.
Bulk formats such as 600L and 1000L containers have gained ground for straightforward reasons: they improve logistics efficiency, reduce packaging weight compared with rigid alternatives, and simplify disposal and storage. But the operational realities of working with large flexible liners at scale — handling, filling speed, product recovery, contamination control – remain a practical challenge that the format alone doesn’t solve.
This is where the systems Aran will present at the stand come in.
A key system on display will be the NUTRILINE aseptic, developed together with WERIT. The system pairs a rigid outer container with an advanced flexible inner bag engineered for the safe and efficient transport of liquid food products, integrating into existing filling and dispensing operations while maintaining strict food-safety requirements.
SelfForm 1000L: Rethinking How Large Liners Work on Filling Lines
One of the technologies highlighted at the stand will be the SelfForm 1000L bag, presented through a dedicated video demonstration.
The problem it addresses is familiar to any production manager running large-format liquid filling: standard 1000L pillow-style liners require manual positioning inside the container before filling can begin. The bag must be pulled open, corners adjusted, and the liner guided into place – typically requiring two operators per line. It is time-intensive, ergonomically demanding, and every additional touch point during aseptic filling introduces contamination risk.
How SelfForm Work
The bag uses a proprietary folding design that allows it to unfold and expand automatically during the filling cycle, conforming to the shape of the container without manual intervention. The operator connects the fill line to the fitment, initiates filling, and the bag self-forms as product enters. When filling is complete, the operator disconnects. That is the entire process – two touch points instead of four or more.
Throughput impact
In manual filling operations, typical throughput ranges from 6–8 bags per hour. SelfForm enables rates above 20 bags per hour with a single operator, effectively halving the labor requirement per line while more than doubling output.
Product recovery
Pillow-style liners trap an estimated 3–5% of product in corner folds and dead zones – in a 1000L container, that can mean 30 liters or more of lost product per fill. The SelfForm design, by conforming to the container geometry, achieves evacuation rates up to 99%, recovering product that would otherwise be discarded or require additional handling.
Material and compliance
The SelfForm bag and fitment are fully BPA-free – relevant as the EU’s 2025 ban on BPA in food contact materials takes effect and US state-level restrictions continue to tighten. The fitment is compatible with both steam sterilization and irradiation (gamma and e-beam). Barrier structures are available in two configurations: a high-barrier SuperFlex option (PE/PA/EVOH/PA/PE) for extended shelf life and long-distance distribution, and a standard barrier structure optimized for regional and refrigerated supply chains.
Applications
SelfForm is designed for low-viscosity liquid products, with validated use across dairy (milk, cream, whey concentrates), fruit preparations, liquid eggs, and beverage post-mix concentrates.
Bag-in-Box and Aseptic Packaging
While bulk systems will receive significant attention at the exhibition, Aran will also present its broader expertise in bag-in-box and aseptic flexible packaging across smaller formats.
These solutions remain essential for dairy and milk products, tomato and fruit processing, liquid eggs and sauces, and beverage syrups and concentrates – applications where long shelf life, transport efficiency, and product safety must be maintained without refrigeration.
Aran’s MonoFlex bag-in-box, a mono-material recyclable structure, was recognized with a WorldStar 2026 Award – reflecting its performance in recyclability and suitability for long-distance transport.
For many food manufacturers, packaging decisions increasingly involve evaluating entire system’s performance rather than individual components: barrier properties, filling compatibility, dispensing behavior, and end-of-life recyclability all factor into the choice. This integrated perspective is central to how Aran approaches every format it develops.
Meet the Team at Hall 10 – D40
If you are attending Interpack 2026, we invite you to visit the Aran team at Hall 10, Booth D40 to see the full range of packaging solutions and discuss the operational and engineering challenges shaping liquid food packaging. Meetings can be scheduled in advance throughout the exhibition.
Frequently Asked Questions
What are the main advantages of using SelfForm 1000L bags?
The SelfForm 1000L bag automates the filling process by unfolding itself during the cycle. This reduces manual labor (only 1 operator needed), increases throughput from 8 to over 20 bags per hour, and ensures 99% product recovery, significantly reducing waste.
Is Aran Group’s liquid packaging BPA-free?
Yes. All SelfForm bags and fitments are fully BPA-free, complying with the EU 2025 ban and US state-level restrictions on food contact materials.
What is the NUTRILINE aseptic system?
Developed in collaboration with WERIT, NUTRILINE is an aseptic IBC system that combines a rigid outer container with an advanced flexible liner, designed specifically for the safe transport of liquid food products.
Which industries can use Aran’s Bag-in-Box and Bulk solutions?
Our solutions are optimized for the global food industry, including dairy, fruit preparations, liquid eggs, tomato processing, and beverage concentrates (post-mix).
