SIG has introduced one-litre aseptic carton packs made from Terra Alu-free + Full barrier material without an aluminium layer.<\/p>\n

<\/p>\n

This move aims to reduce the environmental impact compared to standard SIG cartons.<\/p>\n

After success with single-serve cartons, SIG is now applying its aluminium-free material to the juice category and multi-serve formats.<\/p>\n

In parts of Germany, retailer Aldi will use this packaging for its Rio d\u2019oro grape juice, which lowers the carbon footprint of standard multi-serve cartons by 29%.<\/p>\n

The cartons are filled by Quargentan, an Italian food and beverage producer, using its existing SIG Midi 12 Aseptic filling machine.<\/p>\n

The new material reportedly matches the protective qualities and 12-month shelf life of standard SIG aseptic cartons.<\/p>\n

Available worldwide, the packaging material works with existing SIG filling lines, capable of producing up to 24,000 small cartons or 15,000 multi-serve cartons per hour.<\/p>\n

Minimal changes to filling machines are needed, allowing manufacturers to switch easily between aluminium-free and standard materials.<\/p>\n

By eliminating the aluminium layer typically used in cartons for products such as plant-based drinks, juice, or flavoured milk, the material uses over 80% paper and a thin polymer coating to shield against oxygen, light, moisture, and loss of aroma.<\/p>\n

This reduces the number of raw materials used from three to two and, when paired with wood-based polymers, can decrease the carbon footprint of multi-serve SIG cartons by up to 61%.<\/p>\n

SIG Europe president and general manager Jos\u00e9 Matthijsse said: \u201cAt SIG, one of our goals is to increase the paper content in our aseptic cartons to at least 90% -including the closure \u2013 by 2030, allowing further reduction of carbon emissions, and creating a regenerative food packaging system.<\/p>\n

\u201cOn the way there, we have developed this packaging structure that is made of more than 80% paper and reduces the number of raw materials from three to two.<\/p>\n

\u201cThis breakthrough innovation has the potential to streamline the recycling process for aseptic cartons, only requiring the separation of paperboard and polymers.\u201d<\/p>\n

Earlier this month, SIG unveiled its plans<\/a> to expand its advanced aseptic carton production facility in Quer\u00e9taro, Mexico.<\/p>\n
