SEOUL DAIRY IS
BRINGING SIG
TERRA ALU-FREE +
FULL BARRIER TO
SHELVES IN A LANDMARK MOVE TO BOOST SUSTAINABILITY IN
PACKAGING, SEOUL DAIRY COOPERATIVE (SDC), KOREA’S
LEADING MILK PRODUCER, HAS BECOME THE FIRST COMPANY
IN THE COUNTRY TO LAUNCH PRODUCTS IN ALUMINIUM-
LAYER-FREE FULL BARRIER ASEPTIC CARTON PACKS THAT
ARE RECOGNISED AS RECYCLABLE UNDER THE COUNTRY’S
RECYCLABILITY GRADING SYSTEM.

In a first move, SDC will offer organic
white milk in SIG Terra Alu-free + Full
barrier. This innovation, developed
by SIG, is the world’s first full-barrier
aseptic carton packaging material
without an aluminium layer. It provides
the same full-barrier protection as
standard aseptic cartons and the same
shelf life of up to 12 months.

The environmental benefits are
substantial. Although aluminium
accounts for only about 5% of a
standard aseptic carton’s weight,
it contributes about 25% of its
carbon footprint1. Eliminating the
aluminium layer significantly reduces
environmental impact while also
paving the way for simplified recycling.

Green Aseptic™ Awarded JSDA Grand Prize
Green Aseptic, the unique and innovative non-thermal sterilisation system
developed by Dai Nippon Printing’s (DNP) Aseptic Systems division, has been
awarded the Grand Prize of the Research Award by the Japan Soft Drink
Association. Judged by a professional team of researchers and technologists in the
soft drinks sector, the JSDA Research Award recognises significant technological
and environmental contributions to advance the beverage industry.

Green Aseptic is pushing the sustainability
trend by replacing traditional high-
temperature sterilisation processes in
beverage production with a non-heating
sterilisation system. Combining medium-
pressure UV lamps with filters enables
sterile water to be produced at room
16 temperature, saving vast amounts of
energy and reducing CO2 emissions.

Suited for both low and high-acid
beverages, Green Aseptic reduces the
use of steam, water, and electricity,
lowering operating costs for producers.

The system can easily be installed in
Under Korea’s current environmental
regulations, the new packaging
introduced by SDC is officially labelled
recyclable. The aseptic cartons are the
first in Korea to achieve a recyclable
grade from Korea’s recyclability grading
system. This means, the cartons can be
collected and recycled alongside chilled
gable top cartons that currently have a
10 times higher recycling rate in Korea
than conventional aseptic cartons.
