The latest development in linerless labeling technology comes from Gruppo Irplast, an Italian labeling technology firm. Besides cost savings, a major impetus has been the EU Packaging Waste Directive introduced in 1997. Unlike previous linerless attempts, this system appears end-user friendly and does not require huge investments in application machinery. Instead, Irplast’s method uses a compact dispenser adaptable to handle a choice of three different labeling systems as alternatives to conventional PSAs, shrink sleeves or wraparounds. The UK distributor, Advanced Dynamics of Bradford in West Yorkshire, claims the new product can save up to 30 percent of the cost of traditional PSA labels in the packaging and promotion of food, drink and household products.
The labels use biaxially-oriented polypropylene (BOPP) film coated with a solventless adhesive. It provides adequate adhesion, but does not stick on contact with itself, eliminating the need for a release liner. Advanced Dynamics says this doubles the linear amount per roll of labels to reduce label changeover times on dispensers by 50 percent. The risk of substrate dust or adhesive ticks is also eliminated. It adds that the dispensing method can be adapted to suit most packaging lines and customized to accommodate different product shapes. The system offers various applications, including primary labeling, multipack labeling and re-seal features where appropriate.
