Valmet Bio Pack plus, is an add-on system on the unwinding section of the wrapper.
Before reaching the perforation, the packaging paper goes through a double step consisting of an encoder and a set of nozzles.
Therein lies Valmet's inventiveness: the encoder synchronizes the reel with the glue application operated by the nozzles.
The technological innovation is thus able to apply glue on a reel that unwinds at a speed of up to 200 sheets per minute, ensuring extreme precision in targeting the exact application areas, avoiding smearing and ensuring rapid drying of the adhesive.
The ability to dictate the required amount of glue for each specific package format therefore means minimizing waste and costs, and ensuring more sustainable products, making the entire packaging process even more eco-friendly.
