CAPS & CLOSURES 20 PET planet Insider Vol. 19 No. 12/18 www.petpla.net Closure solutions for the dairy industry UV light barrier caps in all colours Dairy products belong to a growing product group in global food consumption. Liquid dairy products are forecasted to grow by 30% between the years 2010 and 2020 to reach 350 billion liters. What will be essential for a sustainable growth of the industry will be a light, economic, environmental- friendly packaging of the products – while at the same time convenience demands increase continuously. In the fast-growing product seg- ment of dairy goods, the protection of the products through the packaging is crucial, since milk and dairy products are expected to keep their preferred taste, vitamin content, and colour. Especially for long-life dairy products with a longer shelf life, this poses great challenges to the industry. The packaging must meet optimum asep- tic and hygienic standards and protect its contents from external influences for at least the promised shelf-life. At the same time, however, consumers in the “to-go” era attach great impor- tance to ensuring that the products, respectively their packaging, are handy, lightweight, easy to transport and, above all, reclosable. In this context, the closure is just as crucial as the PET bottle itself. Special requirements are placed on closures for long life dairy products. “While closures for fresh milk must be primarily liquid-impermeable because of their short shelf life, in aseptically filled products additional protection against the ingress of microorganisms and impact of light is crucial”, says Christoph Thünemann, Group Direc- tor Communication and Marketing at Bericap. For a long time, this greatly restricted the design of the packag- ing and thus the differentiation of the products at the POS. To achieve maximum opacity, special-coloured masterbatches that provide a UV bar- rier should be used. However, these limited the possible colour variations. Bericap has succeeded in devel- oping an optimal UV light barrier solution, which enables the produc- tion of screw caps in all colours. The product range encompasses light weight screw caps for 38mm neck and the 33mm neck and provides numerous customised closure solu- tions to this market. The 33mm size has now become established as a new, user-friendly, weight-optimised closure – also for dairy products – in several European countries. Closure specifications for premium products like oxygen reduction or aseptic filling are not a challenge for the packaging experts from Budenheim in Germany. “Our closure solutions with incorpo- rated oxygen scavenger – O 2 reduced headspace bottles – provide maxi- mum quality standards. And based on our vast experience in closure solu- tions for aseptic filling, we offer the necessary technical customer service, as well”, Thünemann explains. Overcaps, decoration and custom design Bericap supplies both customised closure designs and overcaps which can be used for small volume promo- tions or for long-term customisation of the package. They can be clipped onto almost all screw caps available in the company’s portfolio. “One of the most significant recognitions from market research and marketing theory is that a product’s customisation strongly influences consumer behav- iour. It is a matter of course that we offer our customers a broad range of personalised and customised features so that their products stand out at the point of sale. Our solutions include top printing, embossing, debossing, laser coding and pad printing”, Thünemann concludes. www.bericap.com
