A new diecutting technology, called Avery Dennison ThinStream allows the diecutting of labels with a liner as thin as 12 microns, half of the current minimum in the market. ThinStream technology also eliminates die strikes, one of the industry’s main quality concerns. The patented technology for ThinStream has been licensed to the Gallus Group, which has created the Gallus Cold Die Unit to accomplish this advance in diecutting technology.
According to Avery Dennison, diecutting with liner caliper below 23 microns was virtually impossible until the advent of ThinStream. With conventional kiss-cutting, the die can cut through the liner and cause operational and quality problems during converting and dispensing. In the cold die process, the facestock is delaminated from the liner before cutting. The face material is then chilled abruptly to -22° C or lower and then cut with a solid or flexible rotary die. The materials are then re-laminated within milliseconds.
“Liner was a top item on our innovation agenda,” said Don Nolan, group vice president, Label & Packaging Materials for Avery Dennison. “We wanted to combine our extensive material manufacturing expertise with technologies that allow us and our customers to further enhance label performance while also reducing liner waste and providing environmental and cost benefits. ThinStream is proof that collaboration across key industry disciplines places Avery Dennison and our partners at the center of a whole new wave of innovations in the label and packaging industry.”
