At a time when SIG is experiencing a shift in demand towards aseptic carton packaging without aluminum layers, Hochwald, one of Europe’s leading dairy companies, is spearheading this move by introducing UHT milk in SIG carton packaging without aluminum layers. Using SIG Terra Alu-free packaging material further reduces the already low carbon footprint of SIG’s standard packaging material by up to 34%*.

By opting for SIG Terra Alu-free, Hochwald is sending out a clear signal for greater sustainability and providing consumers with a more sustainable choice, not least through the reduction in CO₂e emissions thanks to the carton packaging’s simplified material structure. The environmental benefits are clearly communicated to consumers on the outside of the carton packaging. SIG Terra Alu-free packaging material consists of 82% FSC®-certified cardboard from renewable raw materials and features ultra-thin polymer layers that protect food and beverages for extended periods of time without any need for refrigeration.

Volker Kölsch, Head of Procurement at Hochwald, explains, “We have committed to reducing our CO₂ emissions by at least 50% within ten years as part of our ongoing efforts to protect the environment. Our partnership with SIG is a key step towards achieving this goal. By using SIG Terra Alu-free packaging material for our UHT milk products in SIG MidiBloc and SIG SlimlineBloc carton packaging, we’re increasing the share of renewable materials in the packaging and significantly reducing CO₂e emissions by eliminating the aluminum layer.”

Both SIG and Hochwald have joined the Science Based Targets Initiative (SBTi) and have had their sustainability goals approved by the SBTi. This includes SIG’s commitment to achieving net-zero greenhouse gas emissions across its entire value chain by 2050.
