What’s the Corner Radius for Pressure Sensitive Labels?

Beginners Guide for Customized Labels by EHG

When you’re looking to create custom pressure sensitive labels for your products, there are a few simple terms you should be aware of from the get-go, things like varnishes, laminations, and different label materials such as paper and film. Once you have a good idea of what these things are, though, there are more specific terms to learn to make sure you come out with the best-looking custom label printing job. Our custom label printing company in Omaha, Epsen Hillmer Graphics, is not only in the business of creating exciting custom labels for your products—we also want you to know as much as you can about the process of designing labels so the process goes smoothly for you from start to finish.

Today we’re going to take some time and explain one of the specific terms we use in the label manufacturing process, the “corner radius.” It sounds like something you’d learn in geometry class, but trust us, the idea is pretty simple and has a huge effect on the outcome of your pressure sensitive labels project. Read on to learn more about the corner radius and how it can affect your labels!

For Pressure Sensitive Labels with Rounded Corners

A pressure sensitive label’s corner radius, simply put, is a measure of how rounded or squared its corners are. A label with corners that are completely square has a corner radius of 0.0, with the value increasing as the corners become more rounded. Why is this an important value to determine in the planning stages of your custom label printing project? There are two reasons, one functional and the other aesthetic.

An Increased Corner Radius Helps with Automatic Label Application

The machines that co-packers use for automatic label application depend on the quick release of pressure sensitive labels from their backing sheets to keep their processes running smoothly, and it’s an accepted fact in the industry that labels with rounded corners release more easily than those with completely square corners. To cut down on the number of labels that are misapplied when using these automatic methods, then, designers often increase the corner radius of pressure sensitive labels, leading to labels that more easily release from their backing sheets.

An Increased Corner Radius Can Be More Aesthetically Pleasing

Depending on the design concept you’ve developed for your pressure sensitive labels, either a square or a rounded corner may make the most sense to use. For example, a label for a product that’s going for an art deco style may find that rounded corners fit the project more than square ones. On the other hand, if you’re looking for a more contemporary look with clean lines, squared edges might be the way to go.

What’s the Right Corner Radius for my Pressure Sensitive Labels?

It all depends on what looks right for your label design. The standard that most in the packaging industry go by is a 1/8” (or .125”) corner radius, which provides a nice, eased edge to your label and allows for easy automatic application.

If you want squared edges, we here at Epsen Hillmer Graphics recommend a 1/64” (.015625”) corner radius to achieve that look while still allowing for ease of application. A corner radius less that this recommended minimum can lead to problems in the automatic application process.
