The Seal of Success

Posted on 9/22/2015 11:19:07 AM By Hallie Forcinio

Adhesives often seal the success of a package so sourcing the right material and equipment is essential.

A good place to look for that optimum combination is the mega packaging show, PACK EXPO Las Vegas. It opens at the Las Vegas Convention Center on Monday, Sept. 28, 2015, and runs through Wednesday, Sept. 30. It occupies the Central Hall plus the upper and lower levels of the South Hall and is co-located for the first time with Pharma EXPO, which is located in the North Hall.

Exhibitors at the show organized by PMMI, The Association for Packaging and Processing Technologies, offer an array of adhesive-related innovations for case sealing and labeling as well as tape, labels and laminations. A quick search of the PACK EXPO Las Vegas exhibitor roster generates a list of 57 exhibitors with adhesive-related products.

As editor of the PACK EXPO Las Vegas Show Daily, I’ve had a sneak peek at a few.


The Model 5500LF Liner‐Free label printer/applicator from Weber Packaging Solutions (Booth C-2220 and Pharma EXPO Booth N-564) relies on a dry adhesive formula from NuLabel Technologies. The printer/applicator cuts the adhesive-coated material to size, activates it with a water-based spray from NuLabel and applies it. The activation formula contains no solids and evaporates almost instantly, eliminating the glue buildup that commonly occurs on linerless systems. Without the traditional pressure-sensitive liner, the roll holds twice as many labels, cuts roll changeovers 50 percent and boosts uptime. Eliminating the liner also eliminates waste.

The hotLAN 310 inline hot-melt labeler from Langguth America (Booth C-5446) is so flexible it can apply full-wrap labels to containers ranging from 211mm to 603mm in diameter. The patented spray-on application reduces glue consumption more than 50 percent and eliminates glue pots, rollers and related maintenance. Tool-less changeover, minimal or no change parts, digital indicators and scales cut changeover time to five minutes. An integrated inspection system checks bar codes and can supply data for traceability.

Hot-melt systems

All the main players in the hot-melt dispensing arena are exhibiting including Graco (C-5440), ITW Dynatec (Booth C-3301), Nordson (Booth C-3000), Robatech USA (Booth C-5625) and Valco Melton (Booth C-1854).

Nordson plans to display its Spectra™ 30 hot-melt control system. With four trigger inputs, four pattern channel outputs, 24 beads per channel and a choice of pattern types, the unit maximizes pattern options. An operator interface with setup wizard, 50-recipe memory, display of real-time system status simplify operation. On-screen troubleshooting and detailed diagnostics minimize downtime.

Valco Melton is demoing its new melt-on-demand Electric Kube™ gluing system and PackChek™ Camera Inspection System inspecting glue stitch patterns in real time. The PackChek inspection system combines thermal and visual imaging for 100% inspection. Melting adhesive as needed prevents charring and plugged nozzles and reduces adhesive consumption and downtime.

Another Valco Melton demo features an All-Electric CHOICE system on a vertical tray-forming machine, which has achieved a 75% reduction in adhesive usage. The lower consumption means a smaller carbon footprint and improved overall equipment effectiveness.


3M (Booth C-3445) has eliminated organic solvents in the production of its Scotch® Box Sealing tape without affecting tape performance. With elimination of solvents in the production of the release coating, the process is now 99% solvent-free since production of the adhesive side of the tape eliminated solvents in 1975. The reduction in greenhouse gas emissions equates to about 100 metric tons of carbon dioxide equivalent. Other benefits include conservation of petroleum resources and positive impact on the plant and its home town, Greenville, South Carolina. In fact 3M and its Greenville production facility is recognized as a Responsible Tape Manufacturer by the Pressure Sensitive Tape Council.

Finally, don’t forget to stop by the Adhesive and Sealant Council booth (C-1251).
