Emballage 2012: Day one

Gorgeous 4-L kegs of Heineken sold at retail, a light-as-a-feather ISBM PET container for dispensing hand soap in institutional settings, and a new PET tray for chilled meat and fish that’s compelling from a sustainable packaging standpoint—all this and a whole lot more were on display at Emballage 2012 on day one.

Stopping traffic at the PDC Europe booth were 4-L PET kegs of Heineken beer decorated in both stretch PE and shrink PVC labels. Called Chill Pak, the all-plastic concept represents a significant breakthrough for Heineken because it replaces a metal version that weighed far more and thus cost more to move through the distribution system. Both the metal and plastic are one-way containers for retail sale. Just as intriguing as the PET container is the dispensing system that comes attached to the top of the kegs. According to PDC Europe, the stretch PE label on the keg shown on the right was used at an early stage of introduction and rollout. Once the innovative package had proven its consumer appeal from a functional perspective, the full-body PVC shrink sleeve label was introduced, primarily because of the enhanced graphic pop that it brings. Printed on this shrink sleeve label is a “thermometer” that tells the consumer how cold the beer is. Labels are applied by a Model STA labeler from PDC.

At the Aoki booth was a fascinating package for St. Joseph, MO-based Hillyard Industries’ range of industrial soaps—the kind of dispensing systems found in factories, hospitals, restaurants, schools, and other institutions. The container is injection stretch blow molded of PET in Aoki’s single-stage method. The remarkable thing about the container is how thin the sidewalls are, an average of 0.15 mm, and how light the container is at 22 g. The appeal for Hillyard is that this replaces a rigid plastic container that did not always dispense the last ounces of product. This package—whose sidewalls are so thin it could almost be called a pouch—collapses in on itself as product exits, so the last of the product is always dispensed instead of being left in the neck area of a rigid plastic container. Speaking of neck areas, that is the one part of this container that retains the rigidity customary in an injection stretch blow molded container. This is necessary for two reasons: to support a threaded cap and to allow Hillyard to suspend the incredibly light container by its neck during filling. Also at the Aoki booth was the single-stage ISBM machine on which the Hillyard container is made: the Model ISBIII 250LL-50S.

The Albert Heijn supermarket brand, well known in Europe, showed up at the Faerchplast booth, where that firm’s MAPET II concept was on display. Designed for chilled fish, chicken, or other proteins, this is a thermoformed monomaterial PET tray with a clear film lidding. To understand why it represents a departure, it helps to look at the container it’s designed to replace. That container is typically made of PET, too. But it also includes a layer of PE so that film lidding can be heat sealed to the flange. The downside to this traditional tray construction is that when the tray reaches the automated sortation systems in the recycle stream, it causes confusion as to whether the tray is PE or PET. What Faerchplast has developed is a way of putting a layer of adhesive on the flange of the thermoformed tray that makes it possible to heat seal a lidding material of PP, PET, or PE. The adhesive won’t interfere with the sortation process nor is there enough of it to contaminate the post-consumer RPET stream. Shown at the Faerchplast booth were two fish packages now available at the Albert Heijn stores, one for salmon and one for large sardines (I think). The sardines package is a two-pack, with a nicely executed perforation down the middle to facilitate separation in the consumer’s hands. It also included a separate compartment. Both packages were notable for their beautiful presentation. Faerchplast emphasizes that this new materials approach is a drop-in solution requiring no new lid sealing equipment.
