South Korea\u2019s Seoul Dairy Cooperative (SDC) has begun packaging its products in Swiss packaging company SIG\u2019s aluminium-layer-free, full\u2011barrier aseptic carton packs, starting with its organic white milk.<\/p>\n

The packaging uses SIG Terra Alu-free + Full barrier \u2013 the world\u2019s first full-barrier aseptic carton material without an aluminium layer.<\/p>\n

The material provides the same full-barrier protection as standard aseptic cartons and affords the same shelf life of up to 12 months.<\/p>\n

SIG\u2019s alu-free full-barrier solution replaces the conventional three-material aseptic carton structure \u2014 paper, polymers and an aluminium layer \u2014 with two main raw materials: Forest Stewardship Council trademarked and certified paperboard and polymers, substituting the aluminium with an ultra-thin polymer layer.<\/p>\n

The move is presented as having substantial environmental benefits.<\/p>\n

Although aluminium represents only 5% of a standard aseptic carton\u2019s weight, SIG states it contributes roughly 25% of the carton\u2019s carbon footprint.<\/p>\n

Under current South Korean environmental regulations, the new packaging is officially labelled recyclable.<\/p>\n

The aseptic cartons are the first in South Korea to achieve a recyclable grade from the country\u2019s recyclability grading system, meaning they can be collected and recycled alongside chilled gable-top cartons.<\/p>\n

SDC president and CEO Jinsup Moon stated: \u201cBy adopting SIG Terra Alu-free + Full barrier, we are taking a significant step toward enhanced recycling and supporting Korea\u2019s drive for a circular economy.\u201d<\/p>\n

In May 2025, SIG revealed the commercial launch of the Terra Alu-free + Full barrier solution for multi-serve aseptic cartons<\/a>.<\/p>\n

In July, the company introduced one-litre aseptic carton packs<\/a> made from Terra Alu-free + Full barrier material without an aluminium layer.<\/p>\n

SIG first introduced an aluminium-layer-free material for aseptic cartons in 2010 with SIG Terra Alu-free and has since sold over four billion packs without an aluminium layer.<\/p>\n

With the Terra Alu-free + Full barrier variant, SIG has expanded its alu-layer-free options for use with oxygen-sensitive products such as fruit juices, nectars, flavoured milk and plant-based beverages. It has sold more than 400 million packs of the full-barrier material since 2023.<\/p>\n
