Functionality, efficiency, cost-effectiveness and sustainability: professional packaging must always combine several factors. Safety is also a top priority, especially when handling aggressive or hazardous products. With the S-Liner Barrier from Saier, the Scandinavian paint and varnish manufacturer Gjøco has opted for a pioneering packaging solution.
The paint and varnish manufacturer Gjøco from Norway came to the Saier Verpackungstechnik GmbH & Co. KG to: Its metal containers were to be replaced by plastic containers. However, tests with buckets from other manufacturers failed in advance due to the company's solvent-based products. The packaging specialists from the Black Forest rose to this challenge.
Product development with special inliner
Saier has been synonymous with a wide range of high-performance packaging solutions for decades. Gjøco's specific requirement for a Plastic container that reliably withstands solvent-based paints and varnishes was motivation enough to take on this new pioneering product development.
The Saier development team's innovative work focussed in particular on the „inner life“ of the bucket, i.e. the surface where the packaging comes into direct contact with the contents. Various barrier properties of the inner film were therefore tested under live conditions in demanding long-term trials. One Internal and welded barrier film ultimately proved to be effective all-round protection.
After 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 for example, by solvent-containing ingredients and their permeation from the inside to the outside. The product properties of the contents and the stability of the bucket are therefore retained. At the same time, the product is also protected from external influences that could affect the contents. Possible changes to the product properties of the contents, such as those caused by oxygen or UV rays, are thus effectively prevented with the innovative solution from Saier.
Complex savings potential
The result is a success across the board. Following the successful test run, Gjøco has been gradually switching its product packaging from metal containers to the S-Liner Barrier plastic bucket since October 2023. The improved nestability of these empty containers also results in efficient and sustainable outbound and inbound logistics. The empty plastic bucket requires up to 80 per cent less floor space and the packaging weight is reduced by up to 45 per cent for the same filling quantity. The S-Liner Barrier is suitable formould-preserving without denting, does not rust and does not require any additional internal coating for solvent-based products.
Thanks to the embedded opening flap with integrated sealing function, opening is easy and tool-free. The innovative solution from the packaging specialists is also impressive in terms of sustainability: to save up to 70 per cent of the CO2-emissions in the production of the plastic container compared to the metal bucket.

Flexibility capitalised
The S-Liner Barrier from Saier can be customised to different requirements using specific film technology, Whether round, oval or square buckets and sizes from one to 65 litres capacity. The multi-layer barrier layers of the inner film are only a few micrometres thick: this corresponds to only a fraction of the usual wall thicknesses of bucket containers. This is why the Recyclability of the bucket container Depending on the barrier requirement and the selected barrier layer, up to 100 per cent of the barrier is still in place.
