Preserving Perfection: Packaging Technology That Keeps French Fries Crispy and Safe

French fries are more than a side dish today, and the demand for frozen potato products continues to grow. For manufacturers, that means rising pressure to combine stable quality, food safety, and high output, while also making packaging more sustainable and coping with a shortage of skilled operators.

To keep packaging from becoming a bottleneck, fries producers need fast, flexible, and hygienic solutions. At Syntegon, we support manufacturers with technology designed to process and pack fries precisely, seal every bag reliably, and ensure clear coding and traceability at maximum efficiency.

Automation that keeps lines running

With fewer experienced operators available, automation matters more than ever. Syntegon machines are built for easy handling and quick recipe changes. Tool-less changeovers reduce downtime, while guided HMI workflows automatically calculate sensor positions and show the required format parts. Ergonomic features such as reduced working height and retractable conveyors make handling forming sets simple and comfortable, helping teams stay productive even in tight staffing situations.

High-speed vertical packaging for fries

Frozen French fries require high output at low operating cost. Thanks to their elongated shape, fries are ideally suited for vertical packaging. That’s why our SVX series is a perfect fit, delivering industry-leading speeds tailored to this application.

Key benefits at a glance:

Advanced continuous motion profiles minimize vibration and wear. This extends component lifetime and reduces maintenance effort.
Best-in-class product-in-seal detection protects knives and prevents open bags and therefore product losses.
Highly precise dosing systems ensure accurate fills in every bag.
A single line can cover a wide range of market needs: retail packs, large portions for food-service, different pack sizes, and both pillow bags and block bottom bags.

These performance advantages and the high level of flexibility make investing in the SVX series a future-proof decision for the long term.

Tight seals plus less plastic

Even with lower barrier needs, fries packaging must be sealed securely for transport and storage. Thanks to the innovative cross seal drive, we are able to handle the film gently, with a more constant film speed. This ensures constant bag length and stable long seals. Optimized air expellers provide safe packs without relying on perforation. Sustainability is a growing priority, but sharp-edged fries limit material options. Still, our packaging technology enables manufacturers to:

use thinner mono-materials or kraft paper structures,
reduce plastic consumption, costs, and material waste,
extend run times through fewer film changes.

Advanced hot-air long-seal algorithms ensure reliable sealing from the first bag, minimizing startup waste.

Performance backed by lifecycle partnership

Packaging is only perfect when performance is reliable from day one - and stays future-ready. That’s why Syntegon goes beyond delivering machines: as your strategic lifecycle partner we support manufacturers throughout the entire journey, from early planning and smooth installation to ongoing optimization, adaptation to changing market needs, and stable day-to-day operation.

By combining automation, speed, sealing reliability, and sustainable material capability within this lifecycle partnership, we help manufacturers deliver what consumers expect every time: perfectly packed, high-quality French fries.
