Coating of cosmetic packaging

The production of cosmetic packaging is quite a complex process in which computer graphic designers, DTP specialists, as well as companies dealing with plastic injection and industrial painting take part. High-quality cosmetics packaging is often decorated with varnish coatings and various printing methods. Do you want to find out what varnishing of packaging for the cosmetics industry involves and what decorations are currently dominant? See the article below to learn about the techniques used during production.

Varnishing of cosmetic packaging – types of varnishes and method of their application

Nowadays consumers choose cosmetics not only because of their properties and composition, but also based on visual aspects. This is mainly why cosmetics manufacturers make sure that the packages they prepare are perfect in every detail. In this case, the cosmetic packaging painting service is ideal. The coating gives the packaging shine, appropriate structure and a luxurious appearance, while hiding many imperfections of the product manufacturing process, e.g. flow lines or matting from the injection process.

Professional varnishing of packaging used in the cosmetics industry is performed primarily to protect the surface against mechanical damage, cover defects in the raw material and color fading as a result of UV rays. Experts in this field mainly use two painting methods:

  • Selective, i.e. covering only individual elements of the cosmetic packaging with a varnish coating.
  • Full, i.e. the entire surface of the packaging is painted.

Several varieties of varnishes are used to coat cosmetic packaging, but UV varnishes and conventional varnishes dominate. The most frequently used are UV (light-cured) ones, which are hardened using specialized lamps. Thanks to this, the surface of the packaging is the most durable, it is not damaged or scratched, and the final color remains vivid for a longer time. UV varnishing is performed only on automatic painting lines due to the need to minimize human involvement in the process when the varnish is not yet hardened.

Attention! The process of applying varnish to packaging of cosmetic products, and even to bottles in which finished products are placed, is carried out by specialized industrial paint shops.

Production of cosmetic packaging – what printing methods and what varnish coatings are the most popular?

When producing packaging for the cosmetics industry, several methods of printing a graphic design are used, as well as at least several varieties of material decorations. The standard is screen printing, a method of applying paint to a decorated surface through specialized screens in the form of a stencil. The advantage of this form of varnishing packaging is the expressiveness of colors and the ability to create a 3D effect.

Other methods of decorating cosmetic packaging include:

Hot-stamping, i.e. hot foil stamping directly on the packaging. This way, you can use selective decorations that are durable and do not fade.

Flocking – a decorating method that allows you to apply graphics to glass, wooden, rubber and even plastic packaging. In this case, electrostatic devices are used to apply the pattern.

Pad printing – applying various prints / logos / patterns using the process of applying printing ink (usually thinner-based) using soft silicone (pad).

In addition to printing methods, it is worth mentioning the types of varnish coatings that are the most popular in the cosmetics industry – they all concern liquid varnishing (conventional and UV) and metallization (simple evaporation or PVD):

  • vacuum metallization protected with UV varnishes – this way mirror coatings are obtained, resembling galvanization. Most often, it is a system consisting of three layers: UV basecoat, metallization, UV topcoat. The topcoat can be tinted to obtain multi-colored mirrors.
  • colorless UV varnishing in various levels of gloss – from deep matte, through satin, semi-gloss and high gloss. The aim is not only to provide protective protection for the cosmetic packaging, but also to provide a uniform, colorless coating.
  • conventional painting with metallic grain,
  • conventional soft-touch varnishing (suede coating to the touch),
  • conventional varnishing in the selected color and gloss level – it is most often impossible to obtain a perfectly uniform color after the injection process (without streaks, flow lines, uniform gloss throughout the entire package). This effect is achieved after applying a single-layer varnish coating.

Lacquer decoration makes cosmetic packaging maintain its perfect appearance for a long time and is unique. In our Polish paint shop we can help your product stand out, please contact us and visit our projects section.
