Form-Fill Seal for Sweets

March 16, 2019

A twintube, form-fill-seal (FFS) machine for the packaging of confectionary and snack products, the BVC 145, is a continuous motion unit producing up to 500 bags per minute in a footprint of only 2.85m x 1.325m. The unit produces bags up to 145mm wide and 220mm long, with options to upgrade up to 320mm.


The BVC 145 TwinTube is defined by its namesake two-for-one manufacturing process: following the infeed of packaging materials from a single film roll, the material is subsequently slit into two film webs capable of forming, filling and sealing 250 finished bags per minute. The machine also offers the option of packaging material infeed along two separate film rolls. In either setup, automatic edge control allows for repeatable format changeover and a very tight tolerance on the longitudinal seal.


Each of the BVC 145 TwinTube’s two sides has separate film drive control, which guarantees exact bag lengths. Further sealing force can be adjusted individually on each side, allowing processing of various packaging materials with optimum seal quality. In addition, incorporating a hole punch is possible without reducing the output rate.


The continuous motion BVC 145 TwinTube is equipped with Rovema’s proven Sense & Seal technology, which detects products in the seal area to prevent poorly or incompletely sealed bags. Product detection, including defect rejection, works entirely independently on both sides; while discharging on side one, side two can continue production without constraints – this reduces the number of defective bags by 50%.


The BVC 145 TwinTube’s controls are fully integrated into the machine housing, and the control cabinet can be pulled out completely. Swiveling double safety doors can be fully opened for access to the machine’s working area, and the reel carrier completely opens on all sides to offer optimal access for cleaning, maintenance or adjustments.


A variety of options are available for the BVC 145 Twin Tube machine, including a fully integrated labeler and printer, and product gassing for extended shelf life.
