One of the key benefits of the Tunnel 50 Twin GT is its seamless integration with the Pratika series of packaging machines. This allows for easy and convenient control of every element of heat shrinkage through Schneider Electric electrical and electric components.  When connected to the Pratika automatic packaging machine, all settings can be adjusted from the machine’s touch screen. It is a user-friendly and streamlined experience.

The dual heating chambers with separate adjustment provide enhanced control over the shrinking process. This allows maximum precision and efficiency. The machine also features fan speed and temperature control with thermal insulation and also high transition and shrinking speed. This ensures products are quickly and uniformly shrunk to the desired size.

In addition to its impressive features, the Tunnel 50 Twin GT is also a cost-effective solution for any packaging need. The new plastic conveyor belt is designed to withstand high temperatures, improving product stability as well as reducing wear and tear over time.

For industries that require even greater levels of hygiene and durability, an Stainless version of the Tunnel 50 Twin GT is available, which is made entirely of stainless steel. This version is ideal for food and pharmaceutical industries where cleanliness and product safety are paramount concerns.
