Interpack 2014 – Innovative Packaging (2)

In my second overview of innovative packaging I saw at Interpack, I selected the Beverage Can Cap, Stora Enso’s candy packs, the PrimaPak, and the Kortec retortable plastic food can.

Beverage Cap Can
Resealable Can Closures for Beverages provide both added value and convenience for consumers.  As an open can is not portable, resealable can closures bridge the gap between traditional drinking occasions and the demand of the “generation on-the-go”, the generation with an increasingly mobile lifestyle.

In this light German-based Actega DS GmbH (A12/Hall 11) and the US company Dayton Systems Group present the resealable, non-breakable, recyclable Beverage Cap Can, which provides quick-twist-off re-closeability that was previously only available on glass.
The two-piece can and dome design is engineered to attach to standard can sizes using existing seaming technology and it can be made from new or recycled aluminium material.

The Cap Can production systems is comprised of three pieces of equipment: a dome production system, a cap production system and a seal liner system to line the cap with seal material.

To attain best efforts, especially when pasteurisation is required, an extremely flexible and soft plastic is requested. To meet that requirement  the Dayton Systems Group seal liner machine extrusion melts Actega Svelon 520 pellets and inserts them into the cap, then cold moulds them into the fixed gasket using DSG’s patented sealing profile. The machine is equipped with an extrusion nozzle, cooling system, PC Interface operating system, defective cap reject device, and a cap output counter.
This technique makes the cans capable for pasteurization up to 85°C, hot fill up to 95°C, cold fill, retort, and aseptic filling.

The PrimaPak
Following its successful launch in North America, Clear Lam Packaging Inc., premieres the PrimaPak Packaging System, claimed to be the industry’s first flexible, stackable and reclosable packaging solution, in Europe at the Ilapak booth in Hall 8b, Stand C40.

To create a flexible package capable of being stacked and to better protect products inside, Clear Lam developed a new method of enhancing the package rigidity. The end result is a pop-up box shape that merchandises much better than stand-up pouches for greater brand visibility and consumer appeal. The finished package retains its shape, performs well during transport, and stacks well on retail shelves and in consumer pantries. This makes it well suited for a variety of products including cereals, salty snacks, candy, meat, cheese, coffee, infant formula, detergent pods, pet foods, wet naps and more.

The packaging is designed as a replacement for rigid cans, bottles, jars, trays and to a certain extend for flexible packaging. It is lightweight, stackable and printable on six sides. PrimaPak technology improves cube by 30%. It uses up to 70% less plastic compared to PET-jars. The enhanced cube reduces the need for truck shipments, which reduces fuel consumption and greenhouse gas emissions.

Clear Lam first developed the PrimaPak Vertical Form-Fill-Seal (VFFS) technology using an Ilapak machine platform. The Clear Lam patented technology produces the cubed package with a reclosable feature from proprietary rollstock. No preforms or fitments are used. In the first commercial applications in North America, the packaging was produced on an Ilapak’s Vegatronic 2000 after being modified with Clear Lam’s PrimaPak equipment interface.

New design of candy cups
The general eat-on-the-go trend and such facilities as cup holders in cars and on bikes call for packaging concepts with certain characteristics.

To answer this consumer request Stora Enso Oyj (B20-1/Hall 09) and AR Packaging jointly developed a new packaging concept for chocolate and sweets. The specially-designed candy cups come in several shapes with a variety of closing mechanisms, differentiating the candy cups from traditional cups. The cups are handy to use and catch the eye with their shape and excellent print quality.

The candy cups comprise 100% renewable raw material. The baseboard is Stora Enso’s Cupforma Special with the sugarcane-based PE-Green coating on the inside. The PE-Green barrier provides the necessary protection for the contents. The cups are offset printed to achieve high-quality print results that meet the demands of chocolate and sweets branding.

The concept if the candy cup of different cup shapes was tested in production on AR Packaging cup machines.
One of the specially-designed cups, which probably has the highest potential for commercial success, is produced as a trial for the Interpack 2014, and shown at both the Stora Enso and AR Packaging stands.

The retortable “Klear Can”
The BPA-free multi-layer, PP “Klear Can” co-injection technology from Kortec, Inc. (F54/Hall 11), allows the production of clear PP plastic cans for food packaging. The result, the “Klear Can” provides an attractive alternative to metal cans by providing a clear, see-through PP in a container that features extended shelf life of up to five years.

Kortec, the world’s largest supplier of co-injection systems to the plastics and packaging industries, states that the “Klear Can” is an ideal alternative to metal cans for fruits, vegetables, soups, meats, and other products.

Suitable for retort up to 130°C (265°F), these clear plastic cans have been tested and approved for both retortability and the integrity of the double seam, which was designed to allow the plastic can’s flange to accept traditional (easy open and non-easy open) metal can ends.

Klear Can provides numerous advantages over metal cans, most notably the ability to show the quality of the food products to the consumer at the point of sale. Other advantages include the three-layer plastic construction (PP outer and inner layers, with an EVOH barrier) for a shelf life up to five years and its BPA-free status.
Coloured plastic cans and in-mould labelling are available options.

The “Klear Can” is designed in such a way that existing metal can-filling facilities can easily shift to the use of the plastic cans, with no need for investing in new downstream equipment. “These plastic cans use the same steel or aluminium can ends, same filling equipment, same seaming equipment, and the same retorting and cooling equipment”, states Kortec. “For the canner and the brand owner, there is no need for significant modifications over what happens today”.

That’s it for today. I have two more articles about Interpack in the planning. One with another series of innovative packaging and a second about the Challenges in Packaging Technology. The last one is a result of all what I have seen in technology and systems at Interpack. Rest me just to show you how the exhibitors are spending your money after you have bought their products at Interpack.
