Xeikon’s smart label technology being added to Nordic Label’s product portfolio and Cartes’ launch of Jet D-Screen for digital embellishment of labels were some popular topics discussed in Q2.

Nordic Label, a label manufacturer based in Finland, added digital printing solutions provider Xeikon’s smart label technology with track and trace feature to its product portfolio, according to an article shared by TLMI, a label and packaging industry association. The smart label technology enables brands to track their products by enabling unique information to be integrated into the label in addition to a high security printed code.

Further, Weber Packaging, a manufacturer and supplier of labels and labelling systems, shared an article about label machine manufacturer Cartes’ launch of its digital finishing technology called Jet D-Screen. Digital embellishment has become an important part of label production for alcoholic beverages and luxury items to enable brands to engage with customers. The Jet D-Screen moves and prints over the substrate gradually increasing the thickness of the varnish, which can be embellished after the drying process. It can also be used to embellish prints made on other traditional and digital presses.

Plastics also trended in discussions about retailer AEON partnering with recycling company TerraCycle’s Loop recycling initiative to use reusable packaging for its products, according to an article shared by Sanex Packaging Connections, a packaging consulting company. AEON will no longer use disposable containers for items such as foods, shampoos, and detergents as they can have a negative impact on the climate. The company introduced 13 products from six manufacturers in disposable containers and plans to introduce more such products. Consumers can purchase the products and return the used containers to the Loop return box at AEON’s stores.
