Press manufacturer MPS drew steady crowds
to its booth.
High energy and enthusiasm permeated the six halls of Labelexpo Europe 2011 in Brussels this year, a most welcome change after several years of economic struggle and uncertainty. While the label industry has not suffered quite as much as have other industries, converters and suppliers alike were reserving judgment in the weeks preceding the show, hoping for a positive Labelexpo experience and at the same time expressing caution. But they need not have worried. The industry came to Brussels with plans to expand its technology base, and that meant shopping for everything from presses to plates, software to slitters.
The show organizer reports that 28,636 visitors from 118 countries attended this year’s show – an increase of 18.6 percent over 2009. Labelexpo Europe attracted 550 exhibitors (up from 544 in 2009) was the largest in the event’s history.
Exhibitors heeded the axiom that they should feature new equipment and materials at every trade show. Labelexpo Europe started off on September 28 with the introduction by Avery Dennison and Gallus of the ThinStream process, a method of diecutting thin films with 12 micron release liner using cold temperatures, a first for the industry. From there it was new presses, more versatile dies, better performing inks, refined inspection systems, talented substrates, custom adhesives, and digital combinations of technologies.
By the end of the show four days later, dozens of exhibitors reported that they had gathered strong leads, commitments, and had executed sales on the show floor. Throughout the venue, a great many pieces of equipment sported placards that read “Sold.” Always a good sign.
In his keynote speech at Labelexpo Europe, UPM Raflatac President Jussi Vanhanen presented some of the major findings from a recent market survey commissioned by the company. According to Vanhanen, growth in self-adhesive label demand will continue in Western Europe and North America at a slower pace than in the previous decade, while demand will increase especially in the emerging markets.
“In the developed markets of Europe and North America, the consumption of self-adhesive labels will follow the growth of packaged products. Self-adhesive labels will take marginally market share from other labeling methods. Therefore, the growth rates for the industry will most likely remain at around 1-2 percent per annum. The highest growth rates will be enjoyed in the food and beverage end-use segments where the penetration of the self-adhesive label is rather low,” said Vanhanen.
Nevertheless, on the global level, self-adhesive labeling will enjoy robust growth of around 4-5 percent per year. According to Vanhanen, some 80 percent of this growth will come from emerging markets. This also reflects the shift in global economic power towards the Asian and Latin American countries.
He emphasized that the labeling industry has to work hard for new business opportunities, particularly in the developed markets. “Growth will not come automatically. The industry needs to continue to develop solutions for ever more specialized applications. The self-adhesive label is the most versatile labeling method, and all participants in the value chain need to continue to promote and develop products which make use of its strengths,” Vanhanen continued.
Another challenge to be addressed by the industry is the sustained raw material inflation. “Over the next decade, consumption growth in the emerging markets will continue to drive raw material prices up even if there may be some short breathers in times of economic uncertainty. The best way to combat this inflation is that substrate suppliers and printers develop and commercialize thinner, fit-for-purpose material constructions and leverage the fast-developing recycling opportunities,” Vanhanen emphasized.
A select few of the label industry’s leading companies and individuals were recognized At Labelexpo Europe for their outstanding contribution to the sector as the winners of this year’s Label Industry Global Awards were unveiled. Held at the Event Lounge in Brussels before an audience of 550, the awards celebrate and honor those who promote best practice in the label industry.

A new diecutting technology called Avery Dennison ThinStream allows the diecutting of labels with a liner as thin as 12 microns, half of the current minimum in the market. ThinStream technology also eliminates die strikes, one of the industry’s main quality concerns. The patented technology for ThinStream has been licensed to the Gallus Group, which has created the Gallus Cold Die Unit to accomplish this advance in diecutting technology. According to Avery Dennison, diecutting with liner caliper below 23 microns was virtually impossible until the advent of ThinStream. With conventional kiss-cutting, the die can cut through the liner and cause operational and quality problems during converting and dispensing. In the cold die process, the facestock is delaminated from the liner before cutting. The face material is then chilled abruptly to -22° C or lower and then cut with a solid or flexible rotary die. The materials are then re-laminated within milliseconds. A RotoMetrics die was used in the demonstration of ThinStream at Labelexpo, and the development of the technology was supported by the die manufacturer. “Liner was a top item on our innovation agenda,” said Don Nolan, group vice president, Label & Packaging Materials for Avery Dennison. “We wanted to combine our extensive material manufacturing expertise with technologies that allow us and our customers to further enhance label performance while also reducing liner waste and providing environmental and cost benefits. ThinStream is proof that collaboration across key industry disciplines places Avery Dennison and our partners at the center of a whole new wave of innovations in the label and packaging industry.”

FLEXcon launched its new Thermlfilm HT at Labelexpo, a line of high-temperature polyimide films able to withstand the fluctuating temperatures, abrasion and chemicals inherent in the printed circuit board (PCB) manufacturing process. The company also unveiled its FLEXmount Advantage Transfer Tapes (FATT) and heat stabilized polyesters designed for paint mask applications. The Thermlfilm line is available worldwide to manufacturers that need high-density bar code and alphanumeric PCB labels, including military contractors and manufacturers of electronics, aerospace and automotive goods. The PCB manufacturing process is one of the harshest environments to which pressure sensitive films can be subjected. The material meets industry standards and passes all requirements for this challenging environment. All Thermlfilm HT products are tested to ensure that PCB labels will remain adhered and legible throughout the manufacturing process. FATT tapes are designed for bonding and mounting applications in consumer electronics, automotive, white goods and graphics. Typical applications require transfer tapes in 25µ and 50µ although there are more challenging applications that require tapes out with these standards. The heat stabilized polyesters consist of a choice of two thermal transfer printable base labels (white or hazy silver). These labels are then designed to be overlaminated with the hazy clear product(s) either using one overlaminate or two on top of each other as a multi layer construction.

Rotec label sleeves developed for narrow web printing feature increased dimensional stability and edge stability.
Gallus Group reported strong sales of presses sold during Labelexpo, and the company “anticipates that business will be strong after the fair.” Gallus, which introduced its ECS 340 flexographic “rock press” two years ago, has expanded the capabilities of the press by making several options available to converters. These include register control, aluminum printing cylinder sleeves, diecut depth adjustment, machine software enhancements to further improve production, hot air drying, and a cross-cutting unit with sheet delivery. The trend toward digitalization has made digital printing systems available to Gallus customers, said President Klaus Bachstein. Heidelberg’s Linoprint DriveLine B rollfed inkjet press is on display at the Gallus booth, as is the new high end CSAT ITS 600. CSAT, a German manufacturer, was recently acquired by Heidelberg. Gallus also introduced a digital converting unit, created from ECS 340 modules and supported by the granite base incorporated into that press.
GEW featured the latest version of its VCP UV lamp head at Labelexpo, shown with an infrared (IR) cassette system for water-based inks. These inks and varnishes require hot air dryers to evaporate water content, and on certain presses could require rewebbing between hot air and UV curing systems. But the GEW IR cassette system is designed to simplify the process; it simply slides into the lamp housing in place of the UV cassette. The GEW touch screen automatically recognizes if it is UV or IR. Further enhancements have been made to the company’s e-Brick electronic power supply. The new supply is exhibited for the first time and is claimed by the company to be the smallest available on the market for multi-lamp systems. GEW’s integrated on-line UV monitoring system, also featured at the show, ensures continued UV performance by providing a method to determine the onset of any deterioration in UV output. This permits appropriate maintenance and spare parts planning and avoids premature lamps replacement.

The highlight at SMAG Graphique’s booth was the new high-speed semi-rotary flatbed screen printing station that operates at speeds up to 30m/m. With a maximum print width of 340 mm and a 340 mm repeat length, the print station operates mono-color on a Digital Galaxie at the show, in conjunction with a semi-rotary flexo station and a semi-rotary diecutting station. “This high-speed flatbed screen printer enables label converters to deliver the advantages of screen printing including opacity, chemical resistance, and tactile effects more easily and cost-effectively than ever before,” said Stéphane Rateau, general manager, SMAG Graphique. “Visitors to our stand at Labelexpo will be able to see this printer in action, along with our full range of products for label converters.” Also new on the SMAG Graphique stand is the I-CUT 330, part of the entry level finishing and converting series for digital label converters. The I-CUT 330 (330 mm) offers speeds up to 4 0m/m. The unit complements the established I-CUT 250 (250 mm is a more compact model delivering speeds up to 15 m/m). After the show, the company reported that six Digital Galaxie units were sold, as well as five I-CUT 330s.
Sonic Solutions, a manufacturer of ultrasonic anilox roll cleaning systems based in the United States, continues its success at Labelexpo Europe this year. “Printers have taken notice of the value of our systems,” said Joe Walczak, president. “We don’t offer systems with unnecessary features. They are simple and they work, just like our customers.” Walczak said he was surprised at the reception Sonic Solutions has had this year, considering the state of the world economy. “Everyone is looking for value,” he said, “so I can see why people are looking for us.” Through the second day of Labelexpo, Sonic has sold six systems. On display at the show are two of the most common anilox cleaning systems: the SS-2800 and the most popular SS-6500. “Shows like this,” Walczak declared, “further prove that Sonic Solutions is a global organization working to help printers around the world.”
Stork Prints showed its expertise in different aspects of digital and screen label printing at Labelexpo Europe. On display were the DSI digital label printer and engravers, along with rotary screen printing modules and screens. The DSI UV inkjet label printer combines photographic reproduction quality with a rotary screen “look and feel”, the company says. It achieves visual resolution on labels of up to 1,000 dpi, 3D effects that resemble screen printing, and tonal values as low as 1 percent. Repeat lengths of up to seven meters are possible. The press is modular in design, and can be used for stand-alone printing to use inline with semi-rotary converting. Stork Print’s Rotary Screen Integration (RSI) technology was represented with four printing units at the booth, as well as at the booths of Nilpeter and Omet. The RSI printing modules can be seamlessly integrated into the architecture, software and mechanics of the latest generations of printing presses throughout the industry. Benefits include full interactivity, user friendliness and a shorter learning curve.
Sun Chemical introduced new narrow web ink products at Labelexpo this year. SolarFlex Lightening White is a new ultra-high opacity UV flexo white for maximum hiding power and it works equally well with high volume channeled and standard aniloxes. SolarFlex Nova SL is a low-odor in system based solely on Nestle’s positive list of photo initiators and features excellent UV flexo performance properties. SunCure Starluxe is a UV offset product range designed to provide the highest print quality to labels and packaging. The series has been proven to offer reliable and robust press performance on a range of paper, plastics and metalized substrates. SolarScreen Colours range has been upgraded for higher speed rotary screen printing without loss of definition for increased productivity.

Tools & Production, manufacturer of a wide range of custom, high speed rotary punching equipment, enjoyed a busy Labelexpo 2011 in Brussels, closing new orders at the booth and meeting customers and distributors from many countries around the world. The level of booth activity during the first three days of the show exceeded expectations, and the show was probably one of the busiest Labelexpo shows in memory for T&P.
Tresu, a manufacturer of chambered doctor blade systems for narrow web presses, reported a strong level of interest in its products at Labelexpo Europe this year both from OEMs and from converters. The FlexiPrint Reservoir system was on display at the company’s booth, as well as on the FB 330 press at the Nilpeter stand. Tresu Sales & Technical Manager Henrik Kristensen explained that the chambered system does not require ink to be pumped in or out. “The operator can judge by eye when the reservoir needs replenishing, or the system can use an optional float with a sensor to indicate when more ink is needed,” he said. The chambered system has advantage over an open blade configuration, Kristensen observed. With the open blade system, increased press speed can result in splashing from the ink pan and meter roll operation, but in a chamber the ink is sealed completely in the unit. Tresu’s patented sealing technology keeps ink from escaping the chamber, resulting in a reduction in ink waste and a clean press.

Digital press manufacturer Xeikon exhibited its 3000 series of label presses, and introduced
VariLane, a software plug-in for its X-800 Digital Front End, at Labelexpo this week. With VariLane, printers can create imposition schemes for label runs with different references and with labels of different sizes. This offers printers flexibility to optimize the amount of material used and to maximize print time, further improving production capacity. The company launched a new version of its QA-I toner in spot red and orange at Labelexpo Europe. The new colors feature improved light fastness up to a level six on the Blue Wool scale, and meet FDA food safety requirements for both direct and indirect dry food contact. The range of substrates that can be used on the Xeikon press expanded to include cast polyethylene supplied by MACtac. “To date, the market perceived that it was impossible to use dry toner technology to print on PE,” says Filip Weymans, Xeikon’s business development manager for labels and packaging. “Visitors to our stand are finding out that it is now 100 percent achievable and with the highest levels of print quality. We are printing on cast PE material at the show using the Xeikon 3500, so visitors can see the quality for themselves.”
