Flexible Packaging
COVERIS’ NEW BAG-IN-BAG SOLUTION SUPPORTS EASY RECYCLING
making recycling easy for consumers. By combining the benefits of flexible film and the advantages of paper in addition to a patented technology for easy separation, Coveris answers the growing demand for sustainable packaging solutions without losing focus on a product’s safety and visibility on the shelf. Used mainly for food and pet food, the brand-new Bag-in-Bag solution combines an inner layer with strong barrier properties to protect the contents as well as an outer layer made of paper. Paper is perceived to be an eco-friendly packaging solution. Plastic, on the other hand, preserve the sensitive contents and also offers user-friendly closure options. After usage, the bag’s two components can be easily separated via a precut tape at the bottom of the bag. This special

feature also makes the recycling advantage readily apparent to the consumer at the shelf. The new Bag-in-Bag solution is
available in different formats and can be printed in flexography or rotogravure. Because the external paper layer is a printable surface, Coveris offers high- quality printing options that successfully draw attention to the packaging on the competitive supermarket shelf. “With this sustainable packaging solution,
the team has developed a user-friendly eco- concept that retains the advantages of plastic bags while making recycling easy. We have conducted internal panel tests to measure the efficacy of easy separation and recyclability and we are now pleased to release this innovation to market,” says Eric Valette, head of R&D flexibles, commenting on the launch of the new product.

Datalase launches new coating for flexible packaging printers
D
ataLase has released a new solvent- based range of functional coatings for flexible packaging printers. The
development extends the company’s range from flexographic printing to include gravure printing applications and boosts the company’s activity in the high growth flexible packaging sector around the world. The new solvent-based coatings, created
for use with CO2 lasers, offer an alternative option to continuous inkjet (CIJ) and laser ablation of variable data coding to deliver high contrast, durable, black-on-white codes across a variety of film and foil substrates. The DataLase solution is a two-step
process. First, the printer lays down the DataLase laser-reactive coating as a patch on to a film or foil. This patch can either be surface printed or reverse printed under a barrier laminate layer to provide anti- counterfeit tamper-proof coding. This solution is ideally suited for the demanding pharma industry packaging in particular. A CO2 laser is installed at the point in the
production process where the variable data, e.g. expiry dates, lot codes and/or 2D codes, is to be applied to the product. The patch is activated upon exposure to the CO2 laser beam, printing variable data as required to create highly-legible machine-

readable tamper-proof codes that are ideally suited for applications that require 100 per cent product traceability. Adam Slack, product manager at DataLase, says: “DataLase coding and marking solutions go beyond the capability of standard CIJ or laser ablation processes by allowing manufacturers to benefit from increased productivity, superior traceability and the elimination of inks and solvents from their production halls. Typically, changing from a laser
ablation process to the DataLase solution can increase throughput by up to 30 per cent, depending on the application. Faster coding of machine-readable black-on- white codes means increased throughput, less servicing and maintenance, and fully compliant product packaging.” “DataLase coding is extremely robust and durable avoiding smudging and rub off, which can cause annoying rework and waste for brands, as well as the potential of having to scrap an entire batch if the codes are illegible. This is particularly notable in flexible packaging applications, so we see a great opportunity for growth for DataLase in bringing our technology to this sector. We are continuing to invest in new applications and are excited about supporting brands and printers to assess the benefits of the solution.” Laser-reactive coatings from DataLase
work with CO2 lasers from a variety of suppliers, but the coating has been optimised for use with the SATO range of CO2 lasers, available from DataLase, to ensure a robust best-practice procedure when followed throughout the entire supply chain.
