Opening aids in packaging - traditionally achieved through mechanical processes like the embossing of a corner - demand the application of significant initial force on the part of the user and produce irregular tears. Easy Opening, the selective weakening of packaging film by laser, is a clearly superior method. Laser systems like the StarScribe WD make clever use of the varying optical properties of layers of film. They selectively weaken the mechanically supporting layers without damaging others, such as those sealing off light and moisture. The wrapping always tears exactly along the lasered line. The process is stable enough to be easily implemented into industrial mass production. Contactless and wear-free, it guarantees a high process reliability even at high speeds.

High-volume production

StarScribe WD (web direction) is an extremely high performance system that can be integrated into slitter rewinders of all established manufacturers. Working with CO₂ lasers of up to 2000 watts and up to eight processing heads the system is particularly well suited for the high-volume production of scribing structures along the winding direction. Additionally, StarScribe WD lends itself to cutting films. Whether continuous or broken lines, any scribing structures can be synchronised with printed marks on the film. The system works with a web width of up to 1600 mm and is prepared for laser class 1 security.

A complete family of systems

StarScribe WD is part of a broad range of solutions. From the startup system StarScribe Easy, to StarScribe CW (specialised for 'cross web', i.e. scribing structures perpendicular to the winding direction), to PerfoLas- Film for the perforation of films. Try us! We are happy to produce samples on your material with web widths of up to 600 mm using our in-house winder.
