Tentoma Packaging Solutions has launched a new vacuum unit to collect excess film snippets from its RoRo StretchPack packaging machines, aiming to ensure stable packaging line operation and high-speed wrapping.
The RoRo StretchPack technology is based on wrapping with a stretch hood, traditionally used for vertical five-sided wrapping and securing goods on pallets. Tentoma has developed the technology for horizontal wrapping with stretch hood film, allowing four-sided and six-sided packaging with applications including wrapping rolls and building materials. Compared to traditional wrapping methods such as stretch film wrappers and shrink wrapping, RoRo StretchPack is said to reduce film consumption by 25-60%.
With the new vacuum unit, the company says film snippets can be collected in any container of the customer’s choice, and it can be placed independently of the vacuum unit and the packaging machine. It adds the collected film snippets can be sent for recycling.
Tentoma offers two types of vacuum units – the first is a vacuum unit with an integrated container. When full, the container base plate can be removed and the container emptied. The system notifies operators when the container is nearly full. The packaging process stops when the container is full and automatically resumes when the container is emptied.
The new vacuum unit collects and blows the trimmed film snippets into an external container of the customer’s choice, said to be suitable for customers who have specific requirements for container type and size or wish to place the container independently of the packaging machine, potentially using a shared container for multiple production lines.
In related news, last year ValTara unveiled its Breezy Wrapper, combining the horizontal flow wrapping and vertical bagging of trays and containers into one machine and automatically adjusting films to the product’s length. Users can tap once on the pedal to wrap different products with different lengths.
A few months later, BEUMER Group announced plans to display its stretch hood technology at FACHPACK 2024, targeting improved safety, efficiency, and ergonomic performance. Utilizing ‘thinner yet higher-performance’ types of film, the machine is thought to lower both film consumption and packaging costs.
