"We decided to do this because this hose was mostly used to transport powders or dusts," says Product Manager Torsten Gebhardt. The manufacturing process has also been adapted: The hose is now bonded (rather than welded, as before). In the process, a thermoplastic melt made of the same material as the film is applied to the ends to be welded - and the film is pressed. "You can think of it as bonding with a plastic," Gebhardt says. The advantage: The films are much more tear-resistant and the welds last longer.
The inner smoothness of the hose has also been improved. Like its predecessor, Master-PUR Flat Food A is made of polurethane (PUR). However, a permanent antistatic agent is now added, which is once again significantly more stable over the long term than conventional antistatic agents. The new hose conforms to EU Regulation No. 10/2011 and is approved for food category E (dry food). In the current version, the transparency of the product is once again significantly improved.
