Codestream is a new invisible microscopically thin coating that can be applied by the converter using existing flexo, offset and gravure presses anywhere on a pack and then imaged by laser energy at the end user. Launched by Fuji Hunt Photographic Chemicals at the show and shown in operation at the Domino booth, Codestream uses proprietary FujiFilm technology to provide unalterable marks on all types of substrates. Sales development manager Brad Phillips told Converting Today: “When the aqueous coating is hit by the CO2 laser a colour change is created.” Simple to complex variable data can be written using low power, high speed laser energy (9.3-10.6W), the company claims. The coating can be marked even when protected by a PP outer surface layer, it adds.
Scott Clouston, vice president and general manager of Fuji Hunt said: “We have seen very much interest here. We are very excited with the possibilities that it brings to the packaging, labelling and variable data marketplace. We see it as competitive with thermal transfer, inkjet and laser ablation.” It is compatible with most laser writing equipment currently on production lines. Whether CodeStream is flood or spot coated it is claimed to prevent data manipulation so that if altering is attempted, the mark becomes tamper evident.
Available in North America this quarter the system, which is protected by numerous patents, is being released in Europe in January, 2007, he confirmed.
Seeking to enter the preserve of filmic labels, StoraEnso Global Speciality Papers launched UniSet SA, a new wet strength pressure sensitive label paper for breweries. It was demonstrated running on a Krones label dispensing unit. Designed for performance in all facets of label production, to automated high speed pressure sensitive labelling application, the paper can support complex white and metallized beer label designs and its improved paper rigidity aids in the rapid and clean release of labels from liners, claims the company.
Marketing manager of global speciality papers StoraEnso Cory Boettcher told Converting Today: “We have worked closely with well known beer label converter Inland Labels to optimize the release and also the facestocks. We have also worked closely with Krones to make sure the material would run on conventional applicators. We are achieving good release at up to 1,050 labels/min.” This would allow a brewery to run dual format labels.
Initially the product has been developed for North America, but the company will be looking next to Europe to market UniSet SA.
“It offers cost and sustainability advantages of paper over film pressure sensitive labels,” added David Diekelman, product development director for StoraEnso Global Speciality Papers.
