Beumer Group has introduced sealpac, a f/f/s system to meet the needs of customers in the chemical industry. With the new system, Beumer emphasizes a sustainable mode of operation. High throughput and a compact design are key features of the new system. The system also ensures reproducible weight accuracy of the bags. Furthermore, operators can handle the energy-efficient system ergonomically.
Chemical and petrochemical products are partly characterized by high product temperatures. They may be dimensionally unstable and have special flow characteristics. If these materials are filled into bags, their handling can be extremely difficult. This f/f/s system forms a bag from a prefabricated tubular PE film and fills it with plastic materials like PE, PP, PA, or PS.
This system is equipped with a weighing unit that ensures the quantity of material filled is not too high as this would result in high costs for the manufacturer. On the other hand, the bags must not contain too little material since the specified quantity has to correspond to the actual contents. Thus operators always obtain exact filling weights with the new f/f/s system. Then the system seals the bags with a weight of up to 25 kg so users can handle up to 2,600 bags/hr.
In typical systems available on the market, the bags oscillate from one working post to the next one. The resulting vibrations are transferred to the systems and may lead to wear and tear even after a short period of time. Beumer sealpac guides the bags in a straight movement to the individual working stations. The machine runs smoothly, and there are virtually no vibrations.
In the Beumer sealpac the individual working posts for forming, filling, and closing are of modular design. This division makes work easier for the service personnel since they can check each unit separately and replace it as required. Its symmetrical structure enables the operator to freely decide from which side the system is operated. Moreover, the extremely compact design of the sealpac allows a space-saving and flexible installation.
For this system, Beumer relies on proven components that are freely available on the market. This reduces both the capital cost for operators and the delivery periods for spare parts. Thanks to various options like print mark control, automatic exchange of film rolls, detached film releasing unit, free or rail-based manoeuvrability, and the possibility of processing pre-stretched film, the system can be adapted individually to customer requirements.
The sealpac has a robust design that extends maintenance intervals. Its modular structure enables easy cleaning, and operators can quickly retrofit the system. The sealpac is energy-efficient, environmentally friendly, and provides safe operation. The construction series is equipped with an ergonomic control terminal (an HMI), including an optimized user interface and navigation. This enables personnel to operate the system quickly and easily. Users are provided with an easily understandable and intuitive interaction concept, allowing them to define efficient working sequences.
