The shelf-stable food market is shifting –
co-packers who act now can lead it

The shelf-stable food market is shifting fast as brands and retailers look beyond cans and jars – and co-packers need packaging that keeps costs low, protects quality and supports modern sustainability expectations. Tetra Recart® is designed for this reality, helping you reduce total cost per pack, streamline handling and transport, and deliver the food safety and shelf life your clients expect – all in a modern package that resonates with today's consumers

For co-packers, every investment must strengthen flexibility and performance. As customers look beyond cans and jars, you need a packaging platform that fits your business, opens new category opportunities and protects margins – and modern paper-based cartons can do exactly that.

Reduce the footprint of packages and pallets

Flat-packed Tetra Recart material cuts storage space and handling effort for empty packages, freeing up valuable warehouse and production areas. Once filled, the rectangular cartons enable efficient pallet patterns and stable stacking, so you can move more finished product per truck and simplify in-plant logistics. This helps lower transport cost per unit, reduce manual handling and support smoother flows from material infeed to outbound shipments.3
