Transformation of original reels

The converting process is a transformation of the original reels, obtained from the extrusion or co-extrusion processes. Afterwards, the films can be rewrapped, printed and cut.

The cut

The reel cut is a process of transformation of the original reels into smaller and easier to move around. It’s a simple process that consists of unwrapping industrial reels through converting machines that cut and wrap the plastic up.

A similar work is the one that happens when cutting paper: in this case, the original reel is directly cut into either square-sized or personalized sheets.

The print

When another printing process is required for the internal or external sides, we apply the rotogravure and flexography printing.

In rotogravure printing, the ink is applied directly to the cylinder then transferred to the substrate. Once it dries the colour appears very clear.

A different procedure is the flexography one; this form of printing utilizes a flexible relief plate. It can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging.



Sometimes it is required to pierce the film in order for the packed product to transpire. The piercing is divided into a micro and a macro process.

The micro-piercing is used mostly in the food industry and can be cold or warm.

The warm micro-piercing takes place by heating the needles at around 300 °C. This allows  a better piercing and it reduces the chance of film damage.

The macro-piercing, made by Policart with compressed air, is primarily used in the horticultural and construction fields.
