Using lasers in the flexible packaging industrie to apply a scribing line and/or perforation hole is an on-going trend. To increase customer convinience, these so called “easy-opening” helps the consumer a lot and influences his buying decision of the product. To apply the scribing line, the printed laminate on reel will be lasered on-the-fly on a winder.
The goal of laser perforate small holes in the film, however, is to support a better gas exchange between the poduct (i.e. salad or fruits) to increase freshness and shelf-life.
A fully assembled laser scribing system includes the CO2 laser source itself, a 2- or 3-axis-galvo, controller & software and collimating and focussing optic components. To ensure smallest hole size of less than 60µm, you’d use a fixed optic instead of a galvo for laser perforation.
We would be pleased to support you in any way: Either per phone, e-mail or a personal visit. Thanks to our application lab capabilities we provide marking trials free of charge with your polymer material!
