2009 Pack/Process Expo Focuses on Innovating Sustainability
Pack/Process Expos were larger with fewer attendees; vendor innovation focused on sustainability.
With the recession already under way, the combined shows Pack Expo, Process Expo and Converting & Package Printing Expo drew 44,115 buyer attendees — down only 3 percent from the 2006 megashow — in their five-day November run at Chicago’s McCormick Place. Given the state of the economy, officials of the three associations behind the expo said they were satisfied.
“In today’s current economic conditions, having a slightly lower attendance than the 2006 show is the reality,” said Charles Yuska, president/CEO of Packaging Machinery Manufacturers Institute. “The good news is that the leads data clearly indicates that attendees came with specific projects in mind and focused their time and attention on finding suppliers that can address their immediate packaging concerns.”
However, shortly after show, Steve Schlegel quit as president/CEO of the Food Processing Suppliers Assn., sponsor of Process Expo. No explanation was given by the association. George Melnykovich, longtime co-president remained in charge.
There were 67,964 total attendees, counting exhibitor personnel, at the combined shows. International attendees (5,645) and exhibiting companies (2,281) also were down just less than 10 percent, although square footage was up slightly, to just more than 1.3 million sq. ft.
This year’s theme was “Change, Innovation and Sustainability,” and there was heavy emphasis on the last. Daily keynote speakers addressed the movement to more environmentally friendly packaging. Those speakers were Amy Zettlemoyer-Lazar, packaging director at Sam’s Club and co-manager of Wal-Mart’s Sustainability Value Network, and Robert Parvis, packaging manager at Sam’s Club; Betsy Cohen, vice president of sustainability for Nestlé; Trevor Cusworth, a director at Deloitte Consulting; and Glenn Wright, commercial vice president, Dow Chemical Co.
Following are some of the products introduced at the show.
Lightweighting the package
PrimaPak debuted as part of the company’s EarthClear packaging line. It’s designed to replace traditional jars, bottles and cans with similar-looking but significantly lighter packages formed from rollstock with top and (optional) bottom fitments. In one example, a 16-oz. package for peanuts, a glass jar would weigh 400g (material weight alone), a composite can 68g, PET jar 62g, and PrimaPak would weigh 19g. Thousands of trucks could be eliminated resulting in the reduction of greenhouse gas emissions and fuel consumption.

Identified foreign objects
A powerful new tool for food processors and packers looking to maximize food safety and assure product quality through tracking and control of foreign material, FM Alert enables the company’s G6 optical sorters to capture and save a digital image of every object identified as foreign material. Armed with these images, processors can quickly identify critical quality problems and take corrective action. Software can be customized to capture images of objects that match specific criteria for size, shape, color and structural properties.

Brand-differentiating resealable packaging
Traditional zipper attachment systems often require too large an investment for companies in emerging markets. With a smaller footprint than traditional stand-alone zipper applicators, TopZip Jr. was designed as a baseline version, but is upgradeable to run at higher speeds and with a wide variety of pouch formats and zipper profiles with a low capital investment. TopZip Jr. applies press-to-close, including Zip-Pak Double Zip, in the transverse direction, and can support pillow, block-bottom, quad-seal and stand-up pouches. The technology can run anywhere from 30 bags per minute without ultrasonics to 100 bags per minute. User friendly, the system is ideal for applications that can be a challenge to store conveniently, or keep fresh, such as dried fruits and nuts, cereal, cookies, powdered drinks and soups.
Eye-catching metallic colors
Eye-catching metallic shine for shrink labels can differentiate products at retail. Color-changing effects are possible with the use of special inks that can be printed in rotogravure or flexographic.

Ultrasonic spraying technology
The advantage of ultrasonic spraying is superior transfer efficiency over conventional air pressure spraying systems. Accordingly, there is less bounce back of liquid from the target and a potential for better than 50 percent savings in improved cost of goods. Sono-Tek ultrasonic nozzles will not clog, providing further benefits in downtime and maintenance. The applications for ultrasonic spraying in the food industry are numerous and diverse. They include: coating baked goods with antimicrobials, nutraceuticals, glazes, spices and flavors; coating pan release compounds for baked goods; coating frozen meals with flavored oils, herbal extract and spice solutions; coating fresh cut produce with misc. shelf life and texture-enhancing compounds; coating snacks with moisture and oxygen barrier coatings for shelf life extension; and coating refrigerated dairy and prepared ready-to-eat salads with natural antimicrobial solutions for safety and shelf life extensions.

Detect metal and glass
Thanks to its adaptive technology, GlassChekPlus ensures fast and reliable detection of foreign bodies such as glass, metal and stone, for product quality and safety. It works by simultaneously scanning with one vertical and three horizontal X-rays beams, maximizing coverage and probability of detection within a jar by reducing blind spots in the base, sidewalls and neck. Multiple inspection settings can be stored on a single system ensuring optimum detection whatever the jar’s size or shape. It is especially effective for wide neck jars and offers superior detection on shards of glass, as the four beams cover many possible orientations of placement.
