Types of Tamper Evident Labels

Our tamper evident labels are available in a variety of different options, that can be further suited to your requirements based upon their required purpose.

These secure labels come in a number of different shapes including square, round, oval and rectangular, each with their own variety of different sizes available too, depending on your needs. Each of these labels is provided with strong and reactive adhesives that offer a strong bond to your particular application and come supplied on printed rolls or sheets, ready to go.

There are also different tamper evident options available, including those that leave the word “VOID” on the item they are stuck to, others that leave no mark on the substrate (but still show the word Opened or Tampered and those that are extremely difficult to remove, as they break apart on removal or interference.

We can offer custom solutions for tamper evident labels, where we can print any requirements onto the label, whether it’s a barcode, QR code or unique identification number. These can also be colour coded in order to assist with things like inter-departmental tracking and monitoring.

Our current tamper-evident stickers come in the following types:

1. Type 1: White Permanent

This material is fully synthetic and comes with an aggressive adhesive that gets stronger over time. Once applied, these permanent labels are very difficult to remove and will come off in very small pieces if someone is determined enough to try. They can be printed with your logo, numbering ranges, barcodes and QR codes from data supplied via database or straight numbering ranges. They are suitable for extreme temperatures, outdoor and indoor and will withstand freezing temperatures or high temperatures well over 100 degrees Celsius. This is one of our most popular materials and is often specified by schools, businesses, government, police and hospitals.

2. Type 2: Silver Voiding

A fully synthetic material designed to mark assets, protect warranties and reveal tampering. The void labels come with a very strong two-stage adhesive that has high initial grab and gives you instant protection. Any attempts to remove or replace will reveal a VOID pattern, instantly showing if any unauthorised access, theft or tampering has taken place. These too, offer high and low-temperature resistance and are suitable for external and internal use.

3. No-Mark labels (leaves no residue when removed, but show if tampering has been attempted)

For applications such as Buildings, Transport & Aviation access control. These low residue labels will show if attempts have been made at removing or tampering. Design with access control in mind, these labels have been used for many applications where the residue is not to be left on the surface it has been applied to, once removed. This prevents any damage or cleaning-up required on the items the tags have been applied to. They are suitable for sealing compartments, enclosures, doors and hatches inside and outside, such as planes, buildings, electronic boxes and vehicles. They can also be used for the privacy protection and sealing (obscuring) of camera lenses on mobile phones to prevent unauthorised photos being taken inside high-security factories and at events, such as production and film-sets where it would be catastrophic for photo or video leaks to be broadcast without consent.

4. Vinyl labels with security cuts

This is a more standard label with additional security cuts placed within the design to instigate tearing if attempts of removal take place. This is a cheaper alternative to the Type 2: Silver Voiding as the material is more cost-effective, however, will not show any VOIDING pattern if tampered has taken place.

5. Toughened (with 250-micron thick Polycarbonate protective layer)

This is our robust label solution suitable for high impact and heavy-use zones. This is an under-surface printed label where the printing is protected by means of a thick 250-micron clear shell. We are able to digitally print logos, colour designs, QR codes and barcodes under the surface. These labels have been extensively used by facilities management suppliers, the building trade for items such as tools and scaffolding, hire kit, film production equipment, electronics, restaurant, catering and commercial kitchens. Supplied with 3M adhesive backings, you can be sure we have a solution for you.

6. Toughened Silver Voiding (with 250-micron thick Polycarbonate protective layer)

This contains the uber-robust properties of the toughened tags above, but with the addition of a tamper-evident VOID adhesive to show if removal, theft or tampering has occurred.

What are Tamper Evident Labels & Why Do I Need Them?

Tamper evident labels or otherwise known as anti-tamper labels, are labels that are used to secure any electricals or assets that you or a business owns against theft and tampering. These labels tend to be very bold, standing out and preventing any potential theft, but are also commonly used to help monitor movement and protection of items.

The labels are made with a strong material with strong adhesion to assets and items that you want to track and protect. If the removal of the label is attempted, they make an excellent job of making it evident, either leaving a “”VOID”” or “”opened”” marking within the adhesives residue, or breaking apart and making it difficult for the label to be peeled off.

For companies, large or small, and organisations, tamper evident labels are the ideal solution to maintain a close eye on assets are they are passed around the company or rented out. These labels are also suitable for machinery or even vehicles where necessary.

Barcodes, QR codes and other types of identification can be used on these labels, completely customised if necessary.

Benefits of Tamper Evident Labels

The tamper proof labels that Seareach® produces are used in situations where tampering, warranty claims or tamper evidence is required.

We find that manufacturers who offer some form of warranty or guarantee with their products need these tamper stickers to protect from fraudulent insurance claims and where people swap out items in order to get a free replacement. This can cost brand owners many thousands of pounds and staff hours in fulfilling these claims, as they have no way of uniquely identifying or authenticating their items.

They are also useful for sealing boxes for transit or for sealing bags and other items where tamper evidence is important. These anti-tamper labels are usually supplied on rolls or sheets and can be printed with the company’s logo, a sequential or serial number, a batch number and/or a barcode for scanning capabilities. Sometimes the customer prefers to use a random range of numbers so that they can cross these off a master list to further prevent duplicate numbers.

Another security measure is having an un-copyable hologram on the label which makes the labels very difficult to copy.
