Material innovations dominate proceedings at Interpack 2017
Materials innovations featured heavily at this year’s Interpack show in Germany. In bioplastics, US-based
NatureWorks unveiled a number of innovations of its Ingeo PLA material, including an ultra-thin sealant web from Sidaplax, which claims to reduce the cost of sealant films in flexible packaging. The sealant, called EarthFirst UL, has a lower seal initiation temperature than LLDPE, will laminate to materials includ- ing PET, PP and nylon, and is available in gauges of 9, 12 and 15 microns.
Other Ingeo applications on
show included: Nativia D808 film from Taghleef Industries, which boasts a high grease barrier while being both compostable and heat sealable; a heat-stable cup for dairy and dessert packaging from ISAP Packaging; thermoformed Riiqi cold cups from See Box that are decorated using digital printing; and a high barrier PLA/paper laminate from Constantia Flexibles. FKuR of Germany highlight-
ed an updated range of products, including Bio-Flex FX, which allows the manufac- ture of thin filmed products such as bio-waste bags with higher water retention than starch-based compounds. The materials have a renewable content greater than 50%. Materials in the F 18xx and FX 18xx series are biodegradable in garden compost. The company also introduced new grades of its Terralene polypropylene materials, which are around 35% bio-based. At the same time, Dow
Chemical has developed a new adhesive that it says will maximise resource efficiency and cut packaging costs. Its Adcote L86-500 barrier adhesive can replace PET, metallised and aluminium- based packaging with an all-polyolefin design that is easy to recycle. It is designed for medium barrier applications, and can be used in applica- tions such as coffee and cereal pouches,

snack and dry pet food packs and wet wipes packages. Use with selected existing barrier film products, it can help downgauging and allow layer simplification. The company showcased a number of other materials in its ‘Prototype Boutique’ at the show, including Innate, Agility and Affinity. Amcor showcased its Vento
coffee packaging system – which has built-in venting control, allowing coffee to be packed immediately after roasting with no extra equipment or processes. Vento eliminates hard
valves, added machinery, and extra processing steps by incorporating degassing directly into the laminate, says the company. Liepaja Coffee Factory of
Latvia recently began supply- ing its Konigstern ground coffee in Vento packaging. “The integrated
Vento degassing system allows us to pack immediately after roasting,” said Michael Buresh, sales director for Liepaja Coffee Factory. “It is an
all-in-one option, so all we need to do is order the packaging.” Albis says that its Shelfplus
O2 oxygen scavenger is now available in a wider variety of packaging.
“It has made the jump from thermoforming to flexible
Dow says its Adcote L86-500 barrier adhesive can be used in all-polyolefin packaging
films,” said Roland Schulz, director of marketing for packaging at Albis. “The PE-based masterbatch is used in a laminable PE sealing film and helps improve product quality and shelf life.” Adding the product to
existing bag-in-box films can delay oxidation of the filled product by up to 50%, he said. The product can also now be used in stand-up pouches – producing superior perfor- mance when combined with EVOH or SiOx and AlOx coatings.
Albis also showcased its
work with the Fraunhofer Institute for Process Engi- neering and Packaging (IVV) in Freising, to develop a simple method to measure the oxygen absorption of films. ❙
