Until now, it has been difficult to monitor and ensure that micro holes of consistent quality and diameter have been laser perforated. Typically, these holes have diameters less than 120 microns while the packaging film moves with some 100 – 400 m/min.
Rofin is the first supplier to offer elaborate real-time monitoring of perforation hole diameter and percentage roundness with the VisionPerfoControl. Each laser perforation head will be fitted with a camera and the output of each camera is processed using pattern recognition software to record accurately the dimensions of the holes. This allows for validation of the micro perforation process and eliminates the possibility of incorrect set up (e. g. focus error) from spoiling the output from the perforation system. Furthermore, the recorded data documents 100 % perforation quality of the processed material.
In 2013, Rofin introduced StarMAP, the smart software solution for designing the optimum micro-perforation based on the oxygen-transmission rates of the packed product and individual storage conditions. StarMAP comes with a USDA-approved database of more than 160 products (fruits, vegetables, whole / fresh cut). The solution is well-established already at numerous converters. For a comparatively low investment, it offers package optimization possibilities which used to be reserved for the big players. Thus, individually optimized packaging may increase shelf life up to one week. (Source: Rofin)
