Custom Tamper Evident Labels Guide

One of the best ways to keep your products safe for customers is with quality custom tamper evident labels.

These labels are broken when the product is opened, so consumers know whether or not the item has been “tampered” with. Having custom tamper evident labels reassures the buyer that the product has not been compromised, and its components are trustworthy, fresh and secure.

But when it comes to getting tamper evident seals for your product, where do you start? How do you know what they should look like, what materials to use, and what adhesives to use? We’ve got the answers.

Size and Shape

With help from a custom label maker, you can create a die cut of any shape to seal a lid of a jar or bottle, great for unusually-shaped containers. In the photo above, the tamper evident label is a long, rectangular piece with rounded corners and the words “sealed for your protection”. It’s simple, elegant, and does its job well.

Depending on the size and shape of your product, talk to your label designer about the best shape for your tamper evident seals. They’ll be able to come up with the ideal option for you based on your product’s unique dimensions.


Does your product have to endure harsh climates, corrosion, physical stresses, or rough handling? The materials of the tamper evident labels have to be able to withstand these situations.

Common materials for tamper evident labels allow them to stick onto a product’s surface, so you don’t need heat, water or any special solvents to make them stick. Depending on the type of label adhesive, they can easily be removed if needed. They can also endure some pretty unfriendly environments.


While pressure sensitive labels are the most common material used for tamper evident seals, the strength of the seal makes a major difference in the labels’ success. Weaknesses in the substrate or adhesive may cause the seal to accidentally break and damage the product, ultimately hurting your bottom line. On the other hand, you want the buyer to be able to open the product. It’s a fine line, and one that experienced custom label makers understand well.


Depending on your product, you may want your tamper evident seal to say more than “sealed for your protection.” 

You can add branding components to a tamper evident seal to pull together the look and feel of the rest of your product, including any other labels used on it. For example, you can put your company’s tagline on the tamper evident seal, or your brand colors, or even your logo. You have many options to set yourself apart on every aspect of your custom labels.
