Unilever’s Lux sachets uses eco-friendly flexible packaging
The new packaging offers enhanced recyclability and contributes to reduction of plastic waste.
Toppan Printing has collaborated with Unilever Japan on quality tests resulting in the adoption of mono-material flexible packaging for “Lux Luminique Sachet Set Limited Design,” which is due to go on sale in Japan from April this year. With the problem of plastic waste receiving significant attention, demand for more eco-friendly packaging continues to increase, and companies around the world are taking various measures focused on targets for better circulation of plastic resources used for packaging and containers.
Unilever has announced global commitments for a waste-free world, aiming to halve its use of virgin plastic; help collect and process more plastic than it sells; and ensure that 100% of plastic packaging is designed to be fully reusable, recyclable or compostable. Unilever is transforming its approach to plastic packing through its ‘Less plastic. Better plastic. No plastic.’ framework and making progress around the world. Toppan’s “Sustainable-Value Packaging” was recently launched to include more readily recyclable polyethylene terephthalate (PET) mono-material flexible packaging for individual packages. Toppan has now worked with Unilever Japan to achieve a switch to mono-material composition for individual packages for liquid toiletry products. Conventional individual packages combine a PET substrate with materials such as aluminum and polyethylene. Toppan’s mono-material packaging uses a PET-based grade of GL FILM, a market-leading vapor-deposited transparent barrier film from the GL BARRIER range, and combines it with PET sealant.
The manufacturing method and material composition ensure outstanding oxygen and water vapor barrier performance, provide low adsorption to prevent loss of aroma and quality, and make it possible to prevent reduction of product weight during storage over long periods. The use of a single material improves recyclability, and the absence of aluminium film enables a reduction of roughly 25% in CO2 emissions during packaging manufacture.
