Report: Innovative New Sustainable Packaging at PACK EXPO Las Vegas

PMMI Media Group editors fanned out across the many booths at PACK EXPO Las Vegas to bring you this Innovations Report. Here’s what they saw in the sustainable packaging category.

There was a time when a review of packaging material innovations debuting at a major trade show like PACK EXPO would focus on examples of improved functionality and performance. Think enhanced gas barrier characteristics, antimicrobial properties, improved slip properties for better machineability, or the addition of new tactile elements for even greater shelf impact.Image #1 in the article text.Image #1 in the article text.

But the PMMI Media Group editors who roamed the aisles of PACK EXPO Las Vegas last September looking for new developments in packaging materials found, as you’ll see in the coverage below, that one topic ruled the roost: sustainability. Perhaps this should come as no surprise, considering how clamorous consumers, retailers, and for that matter society in general have become about sustainable packaging. Still, it’s worth noting just how dominant this one aspect of the packaging materials space has become.

Also worth pointing out is that developments in the paper sector are abundant, to say the least. Let’s begin with the all-paper blister pack machine (1) featured at the booth of Starview, an initiative developed jointly by Starview and paperboard converter Rohrer.

“The conversations between Rohrer and Starview have been going on for quite a while,” says Sarah Carson, Head of Marketing at Rohrer. “But in the past year or two the pressure on consumer packaged goods companies to deliver on ambitious sustainable packaging goals by 2025 was increasing considerably, to the point that customer demand started to really ramp up. That included one significant customer who was so serious about the idea that it gave us a powerful business reason to invest in the R&D that it was going to take. Fortunately, we had already established a great partnership with Starview from the machinery side.”

“We had both intended to actually launch this last year at PACK EXPO in Chicago,” says Robert van Gilse, Director of Sales and Marketing at Starview. As we all know, COVID-19 put the kibosh on that plan. But then when customer interest in the concept grew the way that it did, says van Gilse, “We knew it was time to get really serious.”

On the machinery side, a key goal throughout the development process was to come up with tooling that would make it possible for existing customers already running automated Starview blister machines to get in on the all-paper blister option by simply adding an auxiliary feeder to any one of Starview’s FAB (Fully Automated Blister) Series of machines. With this tooling in place, a flat paper blister is picked from a magazine feed and, thanks to precision scoring done by Rohrer, is erected and made ready to receive whatever product the customer happens to be packaging. Then it’s just a matter of applying the blister card and heat sealing card to blister.

As for the paperboard components that come from Rohrer, at the PACK EXPO Las Vegas booth demo the blister was a 20-point SBS and the blister card was a 14-point SBS. The virgin board is FSC certified, notes Carson. She also says that Rohrer, a member of the Sustainable Packaging Coalition, worked with that organization to make it possible for customers to easily get permission to use the SPC’s How2Recycle logo on their blister packages.

Printing, meanwhile, is done on an offset press, and if customers so choose, a window can be die cut into the blister card to provide product visibility. Keep in mind that customers using this all paper blister are producers of products like kitchen gadgets or tooth brushes or pens as opposed to pharmaceutical or healthcare products where such a window would of course be out of the question.

When asked what the All-Paper Blister will cost compared to comparable alternatives, both Carson and van Gilse said there are so many supply chain variables percolating right now that it’s difficult to say.

Innovative trays

Image #2 in the article text.Image #2 in the article text.The Syntegon Kliklok topload carton former known as ACE—developed with a particular focus on ergonomic design, sustainability, and increased efficiency—made its North American debut at PACK EXPO Connects 2020. (Click here for more on this machine.) The ACE (Advanced Carton Erector) was on display once again in Las Vegas, but now it is available with a special head that lets it form a unique compartmented paperboard tray (2) that is certified as compostable. Syntegon sees the new tray as a far more sustainable alternative to the plastic trays that are widely used in packaging cookies, for example.

Samples of the tray shown at PACK EXPO were 18-pt natural kraft, though a range of thicknesses are available from CMPC Biopackaging Boxboard, which produces the tray. Trays can also be offered with a barrier coating, says CMPC Biopackaging Boxboard, that is repulpable, recyclable, and compostable.

The ACE machine is capable of forming either glue-style cartons or lock cartons that require no glue. The paperboard carton introduced at PACK EXPO is a lock style requiring no glue, and Syntegon indicates that a three-head ACE system can handle 120 of these paper trays/min. Adds Syntegon Product Manager Janet Darnley, “Getting mechanical fingers to form a tray like this having compartments as it does is a significant accomplishment, especially when there’s no glue involved.”

On display at the AR Packaging booth was a package just now being launched by Toronto-based Club Coffee that takes full advantage of AR’s Boardio®technology. In an upcoming issue we’ll have feature-length coverage of this recyclable, mostly paperboard alternative to today’s multilayer packaging, which is difficult to recycle.

Other news from AR Packaging is the launch of a paperboard tray concept (3) intended for modified atmosphere packaging of ready meals, processed meat, fresh fish, and other chilled foods. The fully recyclable TrayLite® solution provides an efficient and convenient alternative to full plastic barrier trays and reduces plastics by 85%, says AR Packaging.Image #3 in the article text.Image #3 in the article text.

Alternatives with recycled or renewable plastics are available today, but many brand owners, retailers, and food producers have set targets for fully recyclable packaging with maximized fiber content. By combining its expertise in both cartonboard packaging and flexible high-barrier materials, AR Packaging was able to develop a tray that has an Oxygen Transmission Rate lower than 5 cc/sqm/24r.

Made of sustainably sourced cartonboard, the two-piece paperboard tray is lined and sealed with thin higher barrier mono-material films to ensure product protection and extended shelf life. When asked how film is attached to cartonboard, AR says only this: “The cartonboard and the liner are developed to adhere without any use of glue or adhesive and in a manner that makes it easy for the consumer to separate for recycling after use.” The cartonboard tray, liner, and lidding film—a multilayer PE with a thin EVOH layer for gas barrier purposes—are easy for the consumer to separate from each other and recycle in separate well-established recycling streams across Europe, says AR.

“We are excited to offer a new improved paper tray and support the development towards more circular packaging solutions,” says Yoann Bouvet, Global Sales Director Food Service at AR Packaging. “Designed for recycling and easy to handle, heat, and eat from, TrayLite® is ideal for a wide range of products such as ready meals, chilled meat & fish, and nutritional food. Being lightweight and using 85% less plastic, it is a sustainable alternative to the conventional plastic trays.”

Thanks to the patented design of the tray, the thicknesses of cartonboard can be tailored to the exact needs, and therefore fewer resources are used while tightest seal integrity is achieved. The inner liner is recyclable as mono-material PE with an ultrathin barrier layer that provides the crucial product protection and thereby minimizes food waste. And branding and consumer communication is excellent thanks to the full surface print possibilities on the tray—both inside and outside.

“Our goal is to create safe and sustainable packaging solutions in cooperation with our customers and thereby help meet consumer needs and our customers’ ambitious sustainability targets,” says Harald Schulz, CEO at AR Packaging. “The launch of TrayLite® confirms this commitment and is one more addition to our wide range of creative innovations provided by our multi-category packaging group.”

Developments in pouches

Image #4 in the article text.Image #4 in the article text.UFlex partnered with Mespack, a manufacturer of flexible packaging, end-of-line, and soluble pods equipment, and Hoffer Plastics, a leader in the custom injection molding industry, to develop a sustainable solution that will address the complexities of recycling attached with hot-fill pouches.

These three innovative firms have jointly developed a turnkey solution (4) that not only enables 100% recyclability of hot-fill pouches with its new mono-polymer structure but also the spout caps, thus bringing many ecologically responsible brands closer to reaching their sustainability goals.

Commonly, hot-fill pouches are used to pack ready-to-eat foods, allowing sterile packaging of a range of fresh, cooked, or semi-cooked food, juices, and drinks. It’s used as an alternative to traditional industrial canning methods. The utility of hot-fill pouches has outshone the expectations of consumers due to the functionality of easy storage and direct consumption of food content after heating it within the pack itself.

The newly designed recycle-ready single-material PP-based hot-fill pouch combines the strength of OPP (Oriented PP) & CPP (Cast Unoriented PP) in a layered laminated structure designed by UFlex offering enhanced barrier properties, easy heat seal-ability, and longer shelf life for unrefrigerated food storage. Sealing is done with patented closures from Hoffer Plastics in the form of tamper-evident, strong-seal spout caps. And pouch production features the mechanical integrity of the Mespack HF-series fill and seal machine, which allows efficient fill through the spout of pre-made pouches. The new design offers 100% easy recyclability of the laminated structure and spout cap as well within existing PP recycling streams and infrastructures. These pouches manufactured at a UFlex plant in India will be exported to American markets and will be used primarily for packing edible products such as baby food, food puree, and pet food, etc.
