Waste matrix stripping or removal is an important part of the label converting process. And, while it may seem like a simple part of the process on the surface, failures in waste matrix removal can easily lead to lowered productivity and increased costs.
Additionally, there are a number of parameters that can affect matrix removal, including label shape and size, facestock, adhesive, release liner, the type of die-cutting process used, converting speed, and more.
While there is no one-size-fits-all solution to every matrix removal scenario, there are a few guidelines to follow that will aid in more successful matrix stripping.
- Stay within the printer manufacturers’ guidelines or form design. Typical matrix width is 1/16” or less.
- Too much matrix removed can induce picking and feeding issues.
- The more liner that is exposed, the worse the issues will get. Exposed, unsupported liners can become bent or ‘dog-eared’ during jogging, packaging, handling, inserting into the printer tray, or during picking and feeding through the printer, which can result in jamming.
Other considerations include choosing a label base stock that includes a layflat laminate. There are instances when, once the face is removed, the liner may curl on its own. For this reason, consider a label that features a non-ooze adhesive that will eliminate the need for matrix removal.
For example, Mactac’s MP-910 adhesive is a patented non-ooze permanent adhesive designed to virtually eliminate all sheet edge adhesive bleed and the need to strip a matrix around the edge. It features excellent adhesion to a wide variety of substrates. Learn more about this general-purpose adhesive in our Roll Label Converter Catalog!
