Next gen screen-printing

With its recycled ink from rubber waste and embossed lettering, Stoelzle Glass Group is pushing boundaries with its innovative decoration techniques

Stoelzle Glass Group is a go-to expert in the manufacturing and decoration of outstanding high-quality glass packaging. As demonstrated most recently at September’s Luxepack Monaco show, their innovations set a clear focus on recycling and the environment, both key elements of the Group’s ongoing sustainability strategy.

An ink made from old tyres

For quite some time, the Stoelzle innovation teams – together with external experts – have been working tirelessly on the development of new, eco-friendly inks. It is proud to introduce an innovative, environmentally-friendly black printing ink, which has been developed from rubber waste, exclusively for Stoelzle. The Recovered Carbon Black, which is used as a basis of the new inks, derives from end-of-life tyres. Printed bottles obtain a deep black silk-screen effect, which is unlikely to be distinguished from decoration with common black inks. The recycled ink saves carbon, which is a precious raw material and contributes to reduced rubber waste at the same time.

The recycled ink decor is available in dark black as well as shades of grey and is available at all three Stoelzle Group decoration sites in France, Poland and the UK.

Embossed Lettering

Normally, embossing is done directly via the mould during production of the bottles. Stoelzle offers a cold end embossing, which can be applied to the bottles like a label, which remains invisible. The secret of this outstanding decoration technique lies in the perfect cutting of the embossed features. From looking closely or even touching, no one would guess that such a decoration might in fact be a labelling!

The embossing can be done on flint bottles as well as on already coated ones. There’s almost no limitation in terms of colours: gold, silver, multicolour, gradient, whatever suits best.
In addition, embossed bottles can still be recycled and will therefore be a true part of the circular economy.

Next generation of screen-printing

The Stoelzle decoration teams have set themselves the goal to further develop screen-printing techniques in order to allow utmost fine, distinctive, detailed and almost photo-realistic artworks. The screen-printing is still based on classic inks, but on a much higher level of quality and broad choice of colours.

Eco-friendly powdercoating “Quali Glass Coat 2.0”

Already presented last year, the Quali Glass coat 2.0 technique, Stoelzle’s special powder coating process, has won the “coup de coeur“ at the Formes de Luxe Awards for being both eco-friendly and appealing. The innovative powder coating is completely solvent free and helps save up to 77 percent of CO2 emissions compared to standard lacquering.

Stoelzle Masnières Parfumerie is very proud of its first collaboration with the Editions de Parfums Frédéric Malle teams.

Perfume Gun, a unique collection of home fragrance guns was the first bottle treated with the innovative powder coating technique Quali Glass Coat. Applied to amber bottles, commonly used in the pharmaceutical industry, the 40-micron powder coating gives a perfectly smooth surface with a beautiful high-end matt finish.
