The composition and surface properties of boards has been changing regularly in the last decade. This can create difficulties for previously trusted adhesives.
So H.B. Fuller set itself the task of creating a universal adhesive that would create a strong bond for all boards types - even lightweight sustainable folding box boards. The result is Advantra 9271.
The company teamed up with carton and machine manufacturers during development so that H.B. Fuller is able to state that the reliability, versatility and clean-running performance of this packaging adhesive has been established by extensive testing. Its performance was proven in trials with numerous carton types, reflecting trends toward lightweight, coated and grease-resistant folding box boards. Advantra 9271 provided effective adhesion and gave strong fibre tear.
In addition, it reportedly continued to perform optimally even when running on fast packaging lines and subjected to extremes of heat and cold.
Boxes will stay closed under a wide range of conditions. Advantra 9271 also offers a number of benefits that increase the effectiveness and economy of equipment and processes. One is its ability to achieve excellent adhesion at high line speeds, bonding folding cartons quickly and with minimal need for counter pressure. While throughput is rapid, bead size and placement are precise – resulting in clean application and lower adhesive consumption.
As with all Advantra adhesives its viscosity is consistent, which means that users can ‘set and forget’ the adhesive on their packaging lines, knowing that their packaging operations will continue to run smoothly. There is no stringing to clean up, even in high-speed runs, and no char or gel to block the tank or nozzles. This avoids downtime, minimises maintenance requirements and prevents adhesive wastage, reducing costs even further.
"At H.B. Fuller we aim to connect what matters,” stated Elizabeth Staab, marketing manager, packaging solutions. “In the case of Advantra 9271, this means that users can run their lines at top speeds with more sustainable carton types.”
