BARRIER PACKAGING | MATERIALS
Building a wall: developments
in barrier films Recent advances in barrier film include several improved formulations, refinements to production processes, a new type of active packaging and a bright future for metallisation
While barrier film remains a key element within packaging, it must – along with all other plastic products – be able to show better sustainability. Klöckner Pentaplast (KP) says that a new range
of films aim to make protein packaging easier to recycle.
It says that its new Flexible range – comprising
FlexiLid EH 145 R, FlexiFlow EH 145 R and FlexiVac R – shows how flexible packaging can be created with recyclability in mind. “While sustainability has been topping the priority list for many food businesses, flexible films for the protein market have had a tougher road to packaging circularity,” said Christophe Rossé, marketing director for flexibles at KP. “For a long time, the plastic film packaging used with fresh meat products has been non-recyclable – destined for linear waste streams and, ultimately, incinera- tion or landfill.” FlexiVac R is a recyclable vacuum film that
“represents a major engineering achievement in multi-layer recyclable packaging”, says the com- pany. Developed with Dow Chemical, using its Fusabond technology, FlexiVac R offers high clarity, puncture resistance and food protection through its hermetic sealing performance. It is available in thicknesses of 70-300 microns. FlexiFlow EH 145 R barrier flow wrap film gives high levels of product protection while reducing plastic weight by 75%. The high barrier film

extends shelf life, preserves product quality and – for supply chain versatility – is compatible with all FFS and vertical flow pack machines. FlexiLid EH 145 R claims to be one of the world’s thinnest barrier lidding films. It contains more than 90% PE content and offers high barrier properties, anti-fog features and easy printing. Its high sealabil- ity ensures performance even when sealing through contamination.
Flexible adsorption Aptar CSP Technologies has teamed up with ProAmpac to develop a new type of active packaging. ProActive Intelligence Moisture Protect (MP- 1000) combines Aptar CSP’s three-phase Activ- Polymer technology with ProAmpac’s flexible blown film technology in a patent-pending moisture-adsorbing flexible packaging solution. It is the first in a series of active microclimate management packaging solutions to cut the risk of degradation, maintain potency and improve product performance, say the developers. Activ-Polymer helps to protect sensitive drug
products, probiotics, medical devices, drug delivery systems and foods. By adding it into a flexible film structure, MP-1000 delivers high-quali- ty moisture protection without the need for add-on desiccant sachets. The solution not only adsorbs excess moisture within a package, but also shields
