Editor’s note: Knowing that innovation is the lifeblood of package development, and knowing that interpack 2014 would be awash in new and innovative packaging technologies, we unleashed a special team of editors and contributing editors to comb the aisles of the Düsseldorf Exhibition Center and report back on the packaging technologies they found most intriguing. I was pleased to be part of the team, and I was joined not only by Packaging World Senior Editor Anne Marie Mohan but also by five distinguished packaging professionals from Packaging Technology Integrated Solutions: Mike Richmond, Brian Wagner, Jill Ahern, Peter Menary, Phil McKiernan, and Jocelyne Ehret. Here’s our report. —Pat Reynolds, VP Editor, Packaging World.

Active and intelligent packaging
A research center in Spain specializing in packaging, ITENE has more than 90 technical resources focused on packaging research topics. Their goal is to generate scientific and technical knowledge in packaging, and they have a particular focus in active and intelligent packaging. They have identified three specific areas of focus in this area, including bio-nano composites (nano clays) that disperse into the matrix of biopolymers (PLA). Results indicate barrier enhancement by 20% to 40%.

 

They also have developed scavenging and emitting technologies that are able to increase shelf life of food products by up to 30%. The scavengers are able to take up oxygen, ethylene, moisture, CO2, etc. and the emitters include natural antimicrobials, antioxidants, aromatics, and carbon dioxide. A third area of focus is on indicators/sensors for product communication, including spoilage indicators to enhance food safety. Natural agents detect early spoilage compounds resulting in a color change to the attached label indicator. —Mike Richmond

Cool new portion packs
Easysnap Group out of Bologna, Italy, was on hand to display their “One-Hand Opening Sachet,” (image shown) which they view as the only significant step change in portion-pack containers over the last 20 years. The company also builds the machinery to produce the Easysnap sachet and can provide co-packing services for clients. The Easysnap single-dose pack is designed to replace conventional portion-pack tear-top flexible sachets, small bottles, monodose containers, and thermoformed cups. It’s certified for use with food, medical device, industrial, and cosmetic industries applications. The key concept or convenience is the ability to open and dispense product using only one hand. The Easysnap sachet is held in one hand and then folded with two fingers. When the sachet is folded, a mechanically made center cut (using a patented process) breaks open progressively, allowing the product to flow out in a controlled manner.

These sachets are available in sizes from 1 to 30 mL (possibly larger depending on application). The device has received all major food safety, medical device, and cosmetics certifications. Some examples of food applications are ketchup, salad dressings, syrups, and energizing liquids. Medical and cosmetic applications include liquid medications, ointments, baby care products, hand sanitizer, sun screen, and moisturizer. The Easysnap technology also offers extended shelf life vs. traditional sachet packaging. —Peter Menary

Ultrasonics for vf/f/s
MS Ultrasonic Technology Group has introduced a new, high-speed ultrasonic sealing module for use on vertical form/fill/seal machines producing four-side-sealed bags. MS is touting the benefits of greater sealing speeds and boosting the number of bags produced. Use of this newly designed module results in a continuous sealing process providing higher levels of quality and consistency. When foil is present in the substrate lamination, an active anvil gap regulation compensates for typical variations in foil thickness, which leads to less down time.

The compact design of the MS soniSYS unit allows for ease of installation on existing vf/f/s machines. The unit utilizes titanium tooling to dramatically reduce wear typically seen with thermal sealing. MS Ultrasonic has partnered with Wolf Packaging Machines to make the MS soniSYS unit available on new Wolf vf/f/s machines. —Peter Menary

Barrier compression molding
Multi-layer compression molding technology from Aisapack SA was among the package manufacturing technologies featured at interpack (visit pwgo.to/920). The high-output SFM Bacomex machine is well adapted to producing tube shoulders or spouts with high-barrier properties. Such parts can be cost effectively produced with precise dimensional tolerances.

There are several promising applications in the pipeline, including a barrier tube shoulder with digital printing targeted at the hair color market. This would permit brand owners to replace existing glass and metal solutions. Another application is in the area of barrier capsules, where the goal is to replace metal packaging and monolayer capsules to eliminate any need for secondary packaging in the form of high-barrier flow wrapping. —Brian Wagner

Lidstock becomes a lid
The SEALPAC EasyLid™ (image shown) system combines lidding and tray sealing in a single operation. It’s an alternative to heat-sealing flexible film lidding to a tray and then adding an overwrap to protect the film lidding. This novel approach is based on adding a flange to the outside of an injection-molded polypropylene container that is then sealed to flexible roll stock film in one operation. When the package is used for the first time, the outer container flange comes off with the flexible film, thus creating a reclose feature.

This system offers a number of advantages including: reclosable lid, reduced equipment operations, reduced packaging materials and weight, thereby enhancing sustainability. This system has outputs of up to 160 containers/minute. First to commercialize the innovative concept is German food marketer Gardenfrisch Jung. One appeal of the Easy Lid in this case is that the salad’s components, including the separately packed pouch of dressing, are in separate compartments. By removing the lid, pouring dressing over the salad, and then putting the lid back on, the consumer can shake the salad for a perfectly mixed and ready-to-eat meal. —Mike Richmond

'World’s fastest' carton former
Said to feature “the highest speed in the world,” Kliklok-Woodman’s new TransFormer top-load carton former (image shown) runs both lock- and glue-style cartons at speeds to 120 cartons/min with a single head and in a compact footprint. According to Kliklok-Woodman, it used to require a double- or triple-head machine to achieve these speeds. A combination of technologies powers the TransFormer: a “pitchless” segmented wheel carton feeder; a servo profiled single-head plunger that allows for absolute head-to-cavity positioning; an ergonomic, waist-level hopper; and Allen-Bradley automation technology.

Feeding cartons into such a machine typically requires operators to repetitively reach up to insert carton blanks into the hopper. To ease the process of carton loading, the TransFormer features an ergonomic, waist-level hopper that provides convenient access and the ability to load up to 20 min worth of cartons at once. Blank cartons are then fed into a “rainbow” friction feeder that uses belts, rollers, and servo technology to attain high speeds and smoothly transport cartons to the forming area. There, a servo-driven, single-head forming system delivers the blank into a cavity, precisely folding carton panels into the desired position. The TransFormer then drops the cartons onto a conveyor that carries them downstream for product loading. The TransFormer relies on Allen-Bradley Kinetix 6000 multi-axis servo drives with MP Series™ low-inertia (MPL) servo motors to deliver the precise positioning needed for the TransFormer’s feeder and forming system. —Anne Marie Mohan

New reclosure technology
Consumers will pay for the convenience offered by recloseability. So it’s not surprising that so many new reseal convenience features have been introduced lately. The U.S. and European introduction of a “Velcro-like” solution from Aplix  (image shown) and true package-friendly Velcro™ brand features in the last year have been newsworthy, and consumers seem to like the simple use and audible opening. But you had to know that ITW’s Zip-Pak wouldn’t sit quietly watching competition move into their territory without battling back. Now they’ve done just that with Vector™ no-alignment press-to-seal technology. It’s tactile and offers audible cues, and its seal integrity is impressive.

While talking with Zip-Pak, we learned about another packaging innovation: controlled liquid dosing pouch technology for products like mouthwash and motor oil. Traditionally these have been relegated to clever blow molded bottle designs. But many brand owner companies are looking for ways of replacing rigid packaging formats with flexibles, hoping to save cost, gain sustainability, and deliver the same or similar performance benefits. Now Zip-Pak is helping to advance a controlled dosing pouch technology from TechniPac called PreSure-Lok. It was developed by TechniPac’s Mark Steele. Working samples at interpack exhibited the ability to squeeze liquid into a no-leak compartment in the pouch seal, and then separately dispense the controlled-volume dose. —Brian Wagner

Foamed PE-based films
Dow has developed the MuCell® technology for flexible packaging to create new, light-weight, flexible packaging solutions. Dow has been working on foamed materials for over a decade and is a licensee of the MuCell Technology. The technology includes the mounting of the system onto the extruder and uses a supercritical physical blowing agent (CO2) for cellular nucleation. The finished film has uniform cell sizes of less than 100 micron cells (30-50 microns is more typical). The resulting foamed films can have up to a 30% reduction in carbon footprint.
