Meltpack: Perfect adhesive technologies

“ROSUPACK 2008” exhibition is one of the biggest specialized exhibitions in Russia. This year it was held on June 23-27 in the exhibition centre “KROKUS-EXPO”.

Prior to the 1970’s most manufacturer’s joints in corrugated box were either stapled or glued with a “pot and wheel” system. Since the advent of resin-based adhesives and closed, extrusion application systems, the possibility of running higher speeds with more accurate glue pattern placement became a reality. During the last 30 years, most of the systems installed were based on low-pressure adhesive system and a simple head that contacted that board, usually at an angle. The advent of faster direct-electric valves and further advances in adhesive technology have made jetting the glue from a distance away from the board a valid method for applying adhesives. Non-contact manufacturer’s joint glue application can offer advantages for corrugated converters, but also come with some downsides.
