Aseptic carton packaging supplier SIG has revealed plans to raise the proportion of fibre in its aseptic carton structure.

By 2030, the company pledged to develop a full-barrier aluminium-free aseptic packaging structure with at least 90% fibre content.

SIG sets an interim target of at least 85% fibre content by 2025.

The commitment to scale up the Forest Stewardship Council (FSC)-certified fibre content in its packaging and expanding aluminium-free solutions are part of the company’s larger strategy to achieve higher recyclability of carton packs.

It also highlights SIG’s goal to enable recycling of carton packs anywhere in the world.

The commitment comes in response to the growing consumer demand for more sustainable packaging.

SIG CEO Samuel Sigrist said: “Our carton packs have a low energy intensity, are produced with 100% renewable electricity, and consist predominantly of renewable resources from the forest. Now we want to take this even further by increasing collection and recycling of cartons through existing beverage carton recycling systems, and via paper streams.

“Increasing the proportion of fibre content in aseptic cartons opens this opportunity and aligns with the wider trend towards paperization in the packaging industry. The FSC-certified renewable paperboard used in our packs ensures that we are promoting responsible forestry practices that prioritize biodiversity conservation.”

Last month, SIG announced the approval of its entire group’s net-zero science-based commitments from the Science Based Targets initiative (SBTi).

The company also reported total revenue of €1.54bn ($1.70bn) in the first half of financial year 2023.
