PARIS, France—At PCD Paris 2018, a cosmetics packaging industry trade show, Stoelzle Masnieres has showcased its Quali Glass Coat 2.0, a new decoration process for glass perfumery and cosmetics bottles and jars that features an eco-friendly component.

Following two years of R&D (research and development), the glass decorative process is derived from a technique used in the automotive industry, consisting of a glue-free and solvent-free powder coating.

According to Stoelzle Masnières, the use of powder paint allows it to offer a broad palette of new decorative effects with a very low environmental impact and high mechanical resistance. Among other advantages, this new process allows the development of new shades using thermo-lacquering technology.

Despite some counter-typing constraints, Stoelzle Masnières has successfully tested numerous colors, including the most delicate ones.

Quali Glass Coat 2.0 allows the creation of a spectacular finish with: perfect coverage of all surfaces, high resistance to shock and friction, a wide choice of colors and surface effects, chrome, pearlescent, glitter or shading effects on all or part of a bottle or jar, whether transparent or opaque.

According to Stoelzle, the new technique is suitable for all over-decoration techniques for added personalization, including serigraphy.

Environmental benefits
Due to the zero amount of solvents and very small amount of volatile organic compounds involved in the whole decoration process, Quali Glass Coat 2.0 also offers dramatic ecological advantages.

Furthermore, the recuperation and reintegration of exceeding material produced by over-spraying eliminates both emission and waste.

The powders used in the application process are compliant with Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the restriction of the use of certain hazardous substances (RoHS). These powders contain no lead, mercury, cadmium or chrome, in line with current European regulations.

This process thus constitutes an alternative to lacquering and vacuum metalization.

The cost is almost equivalent to that of lacquering, while it may vary depending on the materials used, since the process can be used to spray all kinds of particles, including the most precious.
