Given a continuously evolving industry that demands continual changes in packaging, dictated by marketing strategies, it was necessary to develop versatile machines that could be adapted to the new trends over time. For this reason, the range of product processing methods has been increased; provision has been made for even smaller minimum dimensions, without sacrificing the maximum dimensions, and in view of new demands, it is possible to create new configurations to meet new demands. In addition to versatility and high reliability, the lack of scraps during the packaging process increases energy savings.
Within the wide range of machines offered, an important place is occupied by the case packers (for paper rolls and folded products), which are divided into two different types: horizontal (side-loading) case packers (ROM) and vertical (top-loading) case packers (RVM). Basically, the machine picks up a blank for an ‘American-style’ slotted case from a magazine, forms and fills it, and then seals the case closed with an adhesive tape or hot glue system.
Case packers feature a 1-metre capacity case magazine that allows high autonomy and the magazine can be topped up/loaded without having to halt the production cycle.
Of equal importance are the shrink-wrappers for paper rolls, conventional two-reel bundlers, and flow-wrap machines of the latest generation. The automatic paper roll wrapper (AL80) is a machine designed for horizontal packaging of products and uses either polyolefin (POF) or polyethylene (LDPE or MDPE) film as the wrapping material. It can handle rolls in single, double or triple collations and wrap up to 210 rolls per minute in the 1×3 collation. The machine creates completely sealed bags containing the desired product configurations. The subsequent heat shrinking allows the bag to perfectly fit the shape of the product inside. This type of packaging is especially well-suited to paper rolls for industrial (AFH) and medical use. The pack is closed on the top by overlapping the film edges; this is followed by ionisation and longitudinal sealing (contactless). The packs are then conveyed to the transversal seal station, where they are separated. The roll completely wrapped with film is made to pass through the shrinking tunnel. Roll packs can be customised with (glueless) label insertion or pre-printed film. With this packaging process, film consumption is approximately 20-25% lower compared with other wrappers available on the market.
