SAIER Group: Innovative plastic container for demanding products

The Scandinavian paint and varnish manufacturer Gjøco has opted for SAIER's pioneering S-LINER BARRIER packaging solution.

SAIER Verpackungstechnik has developed the S-LINER BARRIER as a sustainable and economical alternative to metal buckets for the paint and varnish sector. The Norwegian paint and varnish manufacturer Gjøco approached SAIER with a special requirement. They wanted to replace their metal containers with plastic ones, but tests with other bucket manufacturers failed due to Gjøco's solvent-containing products: The perfect challenge for packaging specialist SAIER!

Functionality, efficiency, economy and sustainability... Professional packaging must always combine several factors. Safety is also a top priority, especially when handling aggressive or hazardous products. As an experienced professional, SAIER has stood for high-performance packaging solutions for decades. Gjøco's specific requirement for a plastic container that reliably withstands solvent-based paints and varnishes provided the impetus for a pioneering product development: The S-LINER BARRIER.

In terms of innovation, the SAIER development team focused on the "inner workings" of the bucket, where the packaging comes into direct contact with the contents. Various barrier properties of the inner film were tested under live conditions in demanding long-term tests. An internal and welded barrier film ultimately proved to offer effective 360° protection. Following the development phase, SAIER was able to hand over the first test samples to Gjøco.

The integrated barrier film protects the plastic polymer from changes caused, for example, by solvent-based ingredients and their permeation from the inside to the outside. This preserves the product properties of the filling material and the stability of the bucket. At the same time, the product is also protected against external influences that could affect the product. Possible changes to the product properties of the contents due to oxygen or UV radiation, for example, are thus effectively avoided thanks to SAIER's innovative solution.

The result is a success across the board. As a result of the successful test run, Gjøco is now switching its product packaging completely from metal containers to the S-LINER BARRIER plastic bucket from SAIER. The improved nestability of empty containers also guarantees efficient and sustainable outbound and inbound logistics. The plastic bucket takes up to 80% less floor space and the packaging weight is reduced by up to 45% for the same filling quantity. The S-LINER BARRIER retains its shape without denting, and does not rust or require additional internal coating for water-soluble products. Thanks to the embedded opening flap with an integrated sealing function, it can be opened easily and without tools. The innovative solution from the Black Forest-based packaging specialist is also highly impressive in terms of sustainability: CO2 emissions are reduced by up to 70% in producing the plastic container compared to the metal bucket – which is good news for the environment.

The S-LINER BARRIER from SAIER can be customised to meet different requirements using foil technology. Whether round, oval or square buckets, the S-LINER BARRIER innerliner technology can be adapted to suit all container shapes and sizes. The multiple barrier layers of the inner film are only a few µm thick and therefore only a fraction of the usual bucket container wall thickness. Therefore, depending on the barrier requirement and the chosen barrier layer, the bucket container is still up to 100% recyclable.

SAIER has once again demonstrated its impressive capacity for innovation with the S-LINER BARRIER, and is delighted to have gained a satisfied partner in Gjøco. Are you looking for innovative new ways to package your products? SAIER will be happy to support you.
