- these instructions, found on many packages, can be surprisingly hard to follow. Classic mechanical opening aids, 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 through laser application, is the perfect remedy. Latest generation laser systems like the StarScribe CW 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.

Cross web

For the rest of the production process, about eighty percent of all bags and pouches have to be arranged on the web so that the Easy Opening application runs perpendicular to the winding direction (cross web). The printing on the wrapping and the structure of the scribing are synchronised through index marks. The StarScribe CW uses up to six CO₂ lasers with high speed scanner heads and an operating range of 700 mm x 700 mm and can be integrated into winder and cutter systems with a web width of up to 1600 mm. This flexible high-capacity technology allows for any user-defined scribing structures and even for scribing both sides of the packaging and freeform trimming.

On-The-Fly

The transport speed of the web is measured and calculated into the motion sequence of the laser beam (On-The-Fly technology). The system automatically adapts to the power-up and -down processes of the installation through a software based on a proven standard LaserCAD application by ROFIN BAASEL, thus providing the perfect conditions for flexible programming and product innovations.

High volume

With an output of up to 1,800 watts, the StarScribe CW is also suited for high-volume production or complicated scribing contours. With the optional software module the system can be simultaneously applied to scribings along the web winding direction. For this application we also recommend our specialised systems StarScribe Easy and StarScribe Easy Remote. Try us! We are happy to produce samples on your material with web widths of up to 600 mm using our in-house winder.
