FG120 Heat shrinking oven
The heat shrinking oven, FG120, is equipped with 4 gas burners allowing a perfect and homogeneus heat shrinking process to protect the package against bad weather conditions and seepage.
The combined shrink hooding machine SH51 hoods and shrinks palletized products with tubular heat shrinking film.
The machine combines and synchronizes three different and independent phases: the preparation of the tubular film, transfer and opening of tubular film, hooding and heat shrinking- merging them together in a single process minimizing the downtime of various devices, providing exceptional levels of productivity (up to 140 packages per hour). The system for gripping and handling the tubular film is independent from the heat shrinking system: hence, the heat shrinking phase not interferes with the gripping phase, ensuring maximum reliability in terms of wear resistance of the components and wires. The lower extremity of the hood, driven internally by 4 grippers is tensioned and driven to the bottom of the package to assure a strong grip, simple and efficient, and to take advantage of the tubular film sizes, resulting in material savings. The burners have been designed to provide a constant heat and to guarantee a soft and uniform heat treatment of the hoods, enabling even the use of the thinnest films.
Moreover, the flame is lightened up only when the heat shrinking is required; therefore, it is more energy efficient than traditional ovens. Ergonomics is behind the project. The reel holder, considered standard up to 3 rolls , thanks to the positioning on a movable carriage , allows a fast, easy and safe access from the ground for reel loading. The combustion air distribution system inside the burner ensures optimum combustion without emission of unburnt gases in the environment. In the absence of flame, the automatic detection device interrupts the gas supply.

The SH77 shrink wrapping machine is a combined machine that uses a single work station to perform the hooding and heat-shrinking operations of the product to be packaged.
The SH77 type automatic hooding machine uses a coil of heat-shrinkable tubular film with side bellows. In the different versions, up to three film reels can be reached.
The film is heat-shrunk on the product by means of a gas-powered ring oven; all functions are controlled by a PLC that manages the automatic and manual operations.
