Coating glass bottles and metal cans with quality colour finishes
Glass is traditionally produced in base colors of white, green, or brown. To manufacture more sophisticated glass packaging, many products, such as cosmetic packaging, are coloured after the fact. Metal drink containers also require decorative colouration to be attractive to the end consumer.
both types of packaging, high quality standards are required for the
color application. The all-purpose, potential-free Openair® Plasma
process is an especially effective support for this coating process.
The advantages of pretreatment with Openair® plasma include (among others):
- Micro-fine plasma cleaning to remove clinging organic particles and impurities
- Use of innovative coating processes possible with plasma coating and alternative color systems (UV coatings, solvent-free coatings)
- Reduce scrap rate (error rate)
- Easy to integrate plasma jets in flatbed and spindle coating systems
These days, it is not just the fragrance that counts when purchasing a perfume; often the packaging is at least as important. At HEINZ-GLAS GmbH, the luxurious glass bottles of the finer brands are treated with Openair® plasma before printing.
