Packaging How the Label

Packaging How the Label Becomes more Sustainable and Flexible An interview with Artem Krukov, Labelling Business Development Director at Sidel In light of increasing regulatory demands globally, labelling today is a highly intricate process that is even more vital to products than ever before. Food and beverage industry players are particularly concerned about the costs of materials and are keen to optimize their investment while increasing brand recognition. With 45 years of experience in the labelling industry and over 5,000 machines installed worldwide, Sidel is one of the leading players in the market, providing the expertise to meet all labelling needs. Artem Krukov at Sidel talks about trends in labelling and how a greater focus on sustainability and flexibility is changing the way labels are created and applied. What are the most important challenges in labelling for the beverage industry? Similar to the manufacturing industry as a whole, beverage producers are searching for greater efficiency and lower total cost of ownership (TCO) for their labelling equipment. There is also Sidel EvoDECO Multi a significant focus on sustainability. The label is one of the main interfaces for communication with the consumer. Companies are changing their labels constantly to respond to fast-changing consumer preferences. How is labelling becoming more sustainable? It is our goal to help customers cut costs on everything from material consumption to maintenance costs. By reducing label thicknesses and surface areas, customers can cut costs and improve the carbon footprint of label production and the labelling process. Label producers are working to ensure that labels do not affect PET recycling. Another important trend is the conversion of labels from shrink sleeves to BOPP labels (plastic roll-fed labels for wraparound application). This is a very important step in bottle labelling, since containers labelled with shrink sleeves are difficult to recycle. Hence, the shift to BOPP labels not only provides recycling capabilities, but also helps companies reduce their carbon footprint even further. What do you mean by that? Historically, labels have caused issues with PET recycling to food-grade standard because the label or the glue has affected the recycling process. Today there are several initiatives that can minimize this impact, namely label surface/size reduction, wash-off glue development and glue application minimisation. All drinks manufacturers focus a lot on glue characteristics. What is the reason for this? We can observe this tendency via two trends. First of all, customers around the world are eager to reduce the amount of glue for three reasons: 1) more glue equals higher costs; 2) less glue usage positively impacts machine cleanliness, which leads to higher efficiency; and 3) glue affects the recycling process. Most importantly, customers want to address all of these factors without sacrificing product quality. The second trend can be seen only in some countries: customers want to increase glue distribution to make label application more solid and stable. Sidel has developed a unique solution that fulfils both requirements, namely by leveraging the BOPP solution, we have developed a laser-engraved glue roller (a standard scope for the roll-fed machine portfolio). Thus, we can have better control of glue distribution and repeatability. As a result, the label can still maintain its optimal quality even with less glue. At the same time, we can manage higher glue quantity as well, and it will be distributed more efficiently over the entire glue strip surface. How does Sidel integrate sustainable solutions in labelling? Sustainability is always at the heart of Sidel. We make every effort to minimize the impact on the environment. 32 food Marketing & Technology • February 2022

Packaging The Sidel EvoDECO labelling solutions minimize electricity and glue consumption via the new melter and glue distribution control. With an integrated glue tank in the roll-fed labeller, a patented vertical melter and heating control, glue is melted on demand and always circulated at a precise temperature and in smaller quantities, increasing label application quality. This enables reduced glue consumption and prevents glue degradation, glue filaments, and glue splashing, for better overall quality and improved sustainability. The solution offers 40% less electricity consumption and needs no gears and transmissions and therefore no lubrication. Label application About lightweighting, how has the move towards lighter bottles affected labelling? Packaging design has a critical impact on the efficiency of the entire supply chain. Over the past 30 years, we have more than halved the weight of a 1.5-L PET bottle, while increasing output speeds by 2.5 times, with considerable savings in terms of raw material and gains from a productivity perspective. Therefore, it is a story about “rightweighting” – making sure that the package is minimized while still maintaining its technical performance and high consumer appeal. Some manufacturers use nitrogen to add resistance and stability to the bottle. Sidel has designed its labellers so that they can manage the extra demands of bottle lightweighting with or even without nitrogen. Labels are key components of any brand marketing mix, allowing manufacturers to differentiate their products and give end consumers the information they need and increasingly expect. The growing variety of beverage types and bottle formats has made labelling increasingly challenging. More than ever, flexibility has become a valuable benefit to beverage producers. Top priorities today are faster product and format changeovers, simple operations and optimised processes that use the same equipment for different label types, while still ensuring consistent uptime. Product personalization is about being able to produce smaller batches of Vertical Melter products with their own labelling in a very short time. Hence, the main challenges are the short timeframe for creating customised graphics and labels. Personalizing the label is a difficult process, as there are so many different elements involved. The change usually starts with marketing and then has to go through design and production phases and lastly storage and transport. In fact, the standard process for a label change can easily take over four months. With the rise of online shopping, there has been a challenge to supply consistent, unique and durable packaging and label solutions. This has opened new opportunities to offer The most advanced solution for handling lightweight bottles is the Super Combi, where the labeller is placed in between the blower and the filler as part of an all-in-one solution. With this setting, labels are applied on the empty bottles handled by the neck, reducing the risk of scratches and improving overall bottle quality. Another crucial factor in labelling is flexibility, and this relates to product personalization. What is it, and how does it affect labels? food Marketing & Technology • February 2022 33
