While it wasn't the case 30 years ago, most flexible packaging printers and converters today know that by retro-fitting their web-fed machinery with direct tension-sensing and control equipment they can control their overall process better while preventing poor quality in finished roll material.

A tension zone is any segment of the press in which the tension on the web (in the machine direction) is isolated from other parts of the process.

For the flexible package printer or converter who works with extensible films and materials, the fight to prevent defect-rendering process deviations never ends.
