Adhesive allows a label to survive an ice box
A method has been devised to apply labels to bottles when they are cooler than their surroundings and thus have surface condensation.
Avery Dennison claims that their Aqua Stick? portfolio avoids the time-consuming and costly practices required until now to prevent condensation during labelling.
?This new portfolio was developed in close collaboration with wine and sparkling wine brand owners, view and takes careful account of real-world conditions faced by adhesives and facestocks, sales ? said Fabien Bourgies, Avery Dennison global wine and spirits segment director. ?With Aqua Stick, we are seeing scrap reductions and faster changeovers, with unique improvements to operational performance for these types of applications.?
Wine and sparkling wine bottles often drop below ambient temperature during label application, and this temperature difference can lead to surface condensation problems and a weakened bond between label and bottle. Dispensers often experience inconsistent label positioning and higher scrap rates as a result.
Materials in the Aqua Stick portfolio use Avery Dennison?s Z3338 emulsion adhesive. Engineered for variable temperature and humid environments, Z3338 absorbs any surface moisture present, removing the need to bring bottles up to room temperature. The adhesive allows in-line processing at up to 600 bottles per minute, with consistent label positioning. Even the exit of the labelling tunnel, where further condensation often appears, apparently poses no problem.
The manufacturer claims that performance continues all of the way through a bottle?s lifecycle. Z3338 can withstand exposure to an ice bucket or cold box, and keep the label firmly in position.
Three facestocks are currently available for Europe in the new Aqua Stick range: Fasson? 60# Uncoated Litho WS, MaxFlex? Bright Silver and Sparkling Asti.
