Automatic insertion of core plugs in nonwovens rolls is now an option for the RoRo StretchPack packaging machines from Tentoma. This machinery has become popular because of the horizontal packaging of rolls in a seamless tubular stretch film provides a 100% waterproof and uniformed packaging.
The new core plug applicator can insert core plugs in rolls with diameters up to 1,400 mm. The diameter of each roll is measured automatically to ensure that the core plug is centred. The applicator has a magazine for more than 100 core plugs. In this way, the high capacity from a fully automated packaging line can be achieved without any bottlenecks.
Besides better packaging quality, RoRo StretchPack also provides more sustainable packaging solutions. It stretches the film while packaging, avoiding excessive use of film. Customers have seen a reduction in film consumption by 25-60% compared to conventional stretch film wrapping and heat shrink packaging. The energy-consuming heat shrink process is also removed from the packaging line as RoRo StretchPack packs and seals in one single operation.
Tentoma A/S, Broager/Denmark, has further refined the technology so it can also be utilized horizontally integrated into a production line.
