They presented innovations, which set a clear focus on eco-friendly aspects and recycling, both key topics in the Groups common sustainability strategy at all sites.An ink made from old tyresFor quite a long time the Stoelzle innovation teams together with external experts have been working on the development of new, eco-friendly inks. Now we can be 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 a 100% 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 reduce rubber waste at the same time. The recycled ink decor is available in dark black colour as well as in shades of grey and is available in all three decoration sites of the Stoelzle Group, in France, Poland and the UK. Embossed LetteringNormally, 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 is the perfect cutting of the embossed features. From looking closely or even touching, no one would guess that such a decoration might 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 true part of the circular economy.Next generation of screen-printingThe Stoelzle decoration teams have set themselves the goal to further develop the 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.Ecofriendly 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 ecofriendly and appealing. The innovative, eco-friendly powder coating is completely solvent free and helps save up to 77% of CO2 emissions compared to standard lacquering. Stoelzle Masnières Parfumerie is very proud of their 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.TigitalAnother kind of powder based decoration is the innovative "Tigital" technology, which allows to achieve photo-realistic artworks whilst saving 85% of CO2 emission compared to classic screen printing. This technique suits well for very small lots and allows a high level of flexibility. Learn more about our decoration techniques!
