Corona treatment for better print quality
PRIPLAK® sheets are treated on both sides, with an electric arc that oxidises the surface of the material.
This fine invisible layer improves the adhesion of inks suitable for printing on polypropylene.

UV Litho
A high rate of output and excellent four colour quality are the two main reasons for using this printing technique with PRIPLAK®. It allows images to be closely matched, thereby enhancing the end product. In addition to the UV litho process, dry offset and Waterless offset can also be used – but this must be specified at the time of ordering.(For more info. see the Printing Chapter.)

UV inkjet
Inkjet technology continues to develop rapidly and enables small to medium sized runs to be printed in high-definition. Super sized sheets can be printed with intense and saturated colours, giving images a new depth. This technological revolution opens up a wide range of applications: from POS to presentation folders, as well as exhibition posters and banners. We are especially pleased with the Priplak® Backlit range which has been specifically designed for the illuminated poster market.

Screen printing
The original method for printing Priplak®, and still popular today. Used with UV as well as one and two pack solvent based inks, screen can deliver a variety of special effects, such as glitter, relief and pearlised prints. It is adaptable to a wide range of sizes and thickness, and is particularly useful for large areas of solid colour.

Hot foil and embossing
A traditional printing technique, which is capable of providing a contemporary and wonderfully distinct impression when used with PRIPLAK®. Ideal for giving a prestigious look to the packaging of luxury products.

Tuto Corona

CORONA treatment can be as a method that generates an electrical discharge by means of an electrode.

Its main advantage is to improve the sruface tension of the treated material. In short, it provides a greater surface adhesion.

At Priplak, the sheet is systematically treated on both sides, which ensures an optimized surface tension for better adhesion or ink or glue. Priplak has a Corona treatment lever of 46 dynes.

Working Process

It all starts with polypropylene granules

The principal component of PRIPLAK® is polypropylene in the form of granules. Before this material was invented, the gaseous residue from oil was burned at a pure loss. It is now recovered to produce polypropylene, thus helping limit pollution of the atmosphere.

The granules are fed into an extruder where they are melted, mixed and homogenised. The paste obtained then passes between cylinders where it is flattened, then cooled and cut into sheets.
