Autopack: Sustainable food packaging – how machines are adapting to eco trends

A big focus for the food industry in the UK is sustainability, from sourcing ingredients that are fair trade and prioritising local economies to ensure waste doesn’t end up in landfill. Food packaging is also going green, and more manufacturers are seeking machines that can adapt and accommodate these new eco-friendly materials.

However, many businesses still overlook the importance of adapting their production lines with eco-friendly packaging machines. While not all machines can handle the new, ever-evolving, range of sustainable materials, factors like automation, smart sensors and data-driven optimisation are helping businesses adapt and meet sustainability initiatives.

New sustainable packaging materials on the line

Traditionally, packaging materials relied on multi-layered plastics that, while extremely moisture and heat resistant as well as featuring high strength, have a very damaging lifecycle and produce a high carbon footprint.

The switch to sustainable alternatives has already begun, with the likes of paper-based, compostable, mono-material and bio-based films being utilised. There are plenty of advantages for a business to switch to these eco-friendly packaging materials, as they can be biodegraded, reused, recycled and produce no harmful toxins – all of which benefits brand reputation.

However, these materials behave very differently to traditional plastics when used in packaging machinery. Sustainable materials are far more temperature sensitive, and require more controlled and precise sealing. Paper-based and cardboard packaging materials aren’t as flexible as traditional plastics, while recyclable film and mono-materials are more prone to tearing and stretching.

How packaging machines are evolving

Machines on a production line need to adapt to and accommodate these eco-friendly packaging materials. Adjustable sealing technologies are a big driver of this change, allowing manufacturers to use lower heat settings that protect recyclable and mono-material films while reducing energy consumption. These systems also help maintain seal integrity across a wider range of materials.

Servo-driven systems are increasingly replacing mechanical drivers, delivering precise, repeatable motion that’s ideal for handling delicate or lightweight packaging. With more precision, businesses are now benefiting from less product damage, improved consistency and higher production speeds without sacrificing quality – a big issue when eco-friendly packaging materials were first being developed.

Flexible, modular machine design is also helping to make changeovers faster and produce less waste. With quicker swaps of tooling and formats, manufacturers can run shorter production batches with greater accuracy, helping to cut down on setup waste and overall material loss.

Automation meets sustainability

Along with the Servo-motors for the packaging machines, other innovative technologies are becoming a key enabler of sustainable packaging operations. Smart sensors and vision systems now monitor fill levels, seal quality and alignment in real time, helping to minimise overfilling, mis-seals and rejected packs. This precise level of control directly translates into reduced material waste and improved compliance with packaging standards.

Manufacturers are now also able to optimise packaging processes thanks to data-driven systems. As well as accommodating the eco-friendly packaging materials, manufacturers can fine-tune processes to use less power and fewer resources while maintaining throughput.

These new, technology-rich automated systems support sustainability reporting, providing key data on energy-usage and waste, helping businesses to refine and reduce their overall carbon footprint.

Real-world applications & use cases

The transition to using both eco-friendly packaging materials and sustainable machinery has benefited a large range of industries and, of course, the planet. In snack food packaging, precise sealing and accurate dosing reduce film usage and product giveaway. Frozen food producers benefit from servo-driven handling that protects packaging integrity at high speeds and low temperatures. In dairy applications, automatic flow meter filling systems and capping machines improve hygiene control and sealing accuracy, as well as reducing rejects. Fresh produce packers also see gains from gentle handling systems, operating at slower speeds with programmed precision that minimises damage and extends shelf life.

The common benefits for all industries adapting their packaging machines include lower material waste, stronger regulatory compliance and scalable equipment that’s ready to adapt to future eco-friendly packaging materials and formats.

What manufacturers should consider when upgrading equipment

If you’re looking to invest in new packaging machinery, it’s important to prioritise compatibility with current and emerging packaging materials, including recyclable and bio-based options. Modular systems are also a great way to be able to scale your production along with the evolving materials.

But cost also plays a big factor. You should weigh the total cost of ownership against sustainability ROI. While advanced machines may require higher upfront investment, reductions in energy use, material waste and downtime will deliver long-term savings.

Partnering with machinery suppliers that actively invest in research and development helps ensure access to ongoing innovations, upgrades and expert support as technologies continue to advance.
