Worried about packages being opened before arrival? Concerned about theft or tampering during shipping? Security tape provides a clear visual sign if someone tried to open your goods.
Security tape is a special kind of adhesive tape designed to show evidence if a package or container has been opened. It leaves behind a message, pattern, or damage when removed, unlike regular tape.
Understanding what security tape is is the first step. But to truly appreciate its value, especially for businesses like yours and mine, you need to know how it actually protects your shipments. Let's look closer at how these tapes work their magic.
How does security tape work?
Concerned that determined thieves can just peel off tape? Worried standard tape offers no real protection? Security tape is different; it’s specifically made to reveal any attempt to remove it.
Security tape works using special layers and adhesives. When someone tries to peel it off, hidden layers separate or adhesive transfers, leaving a permanent message like "VOID" or "OPENED" on the surface.

Let's dive deeper into the mechanics. Normal tape just sticks. Security tape is more complex. Think of it like a sandwich with special layers.
- Top Layer (Face Stock): This is the part you see, often made of polyester or polypropylene. We can print logos or warnings on it.
- Release Layer: A very thin layer designed to break or separate in a specific way.
- Adhesive Layer: This sticks to the box, but it's special. Part of it might stay on the box, and part might stay on the tape, or it might split to reveal a hidden message.
When someone peels the tape:- The bond between the adhesive and the box surface is strong.
- The internal release layer is designed to be the weakest point or to split predictably.
- This controlled failure reveals the hidden tamper evidence.
There are different types:
| Feature | Description | Use Case Example |
|---|
| Total Transfer | Leaves all adhesive & VOID message on surface. | High-security document envelopes. |
| Partial Transfer| Leaves some residue/message. | General carton sealing. |
| Non-Transfer | Shows VOID message on tape itself, clean surface. | Reusable containers, aircraft doors. |
| Frangible | Breaks into tiny pieces upon removal attempt. | Sealing sensitive components. |
For my clients, like printing factories or bag manufacturers, choosing the right type depends on the application and the surface it needs to stick to. We often discuss customization, like adding their company logo into the VOID message for extra security and branding.
How do you remove security tape?
Need to open a package sealed with security tape? Worried about making a mess or damaging the item inside? While you can physically remove it, the whole point is that it shows you did.
You remove security tape simply by peeling it off like regular tape. However, it is designed not to be removed cleanly. It will always leave behind evidence of tampering, like a "VOID" message or torn fragments.
Let’s be clear: security tape isn't designed for easy, neat removal. Its primary job is to prevent undetected opening. Unlike standard packing tape that you might try to peel carefully, security tape is engineered to fail visibly.
If you are the legitimate recipient, you just cut through the tape or peel it back, accepting that the tamper evidence will be triggered. That's its function – showing the package seal was broken.
Some might wonder about clever ways to bypass it:
- Heat: Applying heat (like a hairdryer) might soften the adhesive on regular tape. On security tape, heat often accelerates the tamper-evident feature, making the "VOID" message appear more clearly or causing the face stock to shrink and distort.
- Cold: Freezing sprays are sometimes used. While this can make some adhesives brittle, security tapes often use adhesives formulated to resist temperature changes, or the cold might cause the layers to separate as designed, revealing the message.
- Solvents: Trying to dissolve the adhesive can damage the packaging itself and often interacts unpredictably with the tape layers, still leaving clear signs of tampering.
The bottom line for businesses using this tape: you want it to be difficult or impossible to remove cleanly. That visible evidence is the security feature you are paying for. It tells your customers the package arrived safely, or it provides proof if something went wrong. It's not about preventing opening by an authorized person, but about showing if anyone opened it along the way.
Why does my package have tamper-evident tape?
Received a parcel secured with unusual tape? Wondering why the sender used this specific type? It’s a sign the sender cares about the package arriving safely and unopened.
Your package has tamper-evident tape because the sender wants to protect the contents from theft or interference. It also assures you, the receiver, that the package hasn't been secretly opened during transit.
Seeing security tape on a package is actually a good sign. It means the sender has invested in protecting the shipment. There are several key reasons why businesses, including many of my clients, use it:
-
Deterring Theft: Visible security measures discourage opportunistic thieves during shipping and handling. Warehouse staff or delivery personnel are less likely to tamper with a package if they know it will be obvious.
-
Ensuring Product Integrity: For sensitive goods like electronics, pharmaceuticals, or high-value components, the tape guarantees the product hasn't been swapped, contaminated, or compromised.
-
Building Customer Trust: It shows the end customer that the company takes security seriously. Receiving an intact, securely sealed package builds confidence in the brand. Think about high-end retail or important documents.
-
Compliance and Tracking: In some industries, regulations might require tamper-evident sealing. It also helps in logistics; if a seal is broken, it's easier to pinpoint where in the supply chain the issue occurred.
Here’s a quick breakdown of why different businesses use it:
| Reason | Benefit | Example Industry |
|---|---|---|
| Theft Prevention | Reduces losses during shipping and storage. | Electronics, Luxury Goods |
| Integrity | Guarantees product hasn't been altered or contaminated. | Pharmaceuticals, Food |
| Trust | Increases customer confidence in product and sender. | E-commerce, Banking |
| Accountability | Helps identify where tampering occurred in the supply chain. | Logistics, Forensics |
Many of my customers, like DANNY in Russia who deals in anti-counterfeiting materials, use security tape not just on outgoing shipments but sometimes even incorporate it into their final products (like secure bags or labels). It's a crucial part of their business model to provide security assurances to their own clients.
How does tape work?
Ever stopped to think about regular sticky tape? Assume all adhesive tapes function the same way? Understanding the basics of adhesion highlights why security tape is so specialized.
Standard tape works using a pressure-sensitive adhesive (PSA). When you press the tape onto a surface, the sticky adhesive flows slightly to create a bond, holding items together.
Let's get down to the basics of how simple adhesive tape functions. Most tapes you encounter use what's called a Pressure-Sensitive Adhesive, or PSA. This doesn't require water, solvent, or heat to activate – just pressure.
Imagine the adhesive as a very thick, sticky liquid (it's technically a viscoelastic material).
- When you press: The adhesive flows just enough to make contact with the microscopic hills and valleys of the surface you're sticking it to. This creates a large contact area.
- When you stop pressing: The adhesive is strong enough (has enough internal 'cohesion') to resist flowing further and holds its position, creating a bond.
The main parts are usually: - Backing: The film material (like plastic, paper, or cloth) that carries the adhesive.
- Adhesive: The sticky layer itself.
The goal of regular tape is simple: stick strongly and stay stuck.
Now, compare this to security tape:
| Feature | Regular Tape | Security Tape |
|---|---|---|
| Primary Goal | Stick reliably, hold things together. | Stick, BUT primarily show evidence of removal. |
| Mechanism | Simple PSA bond. | Complex layers, designed failure points, PSA bond. |
| Removal Intent | Ideally removable (sometimes cleanly). | Designed to be impossible to remove cleanly. |
| Indication | No inherent tamper indication. | Built-in "VOID" message, delamination, or fracture. |
So, while both use adhesive, their purpose and construction are fundamentally different. Security tape leverages basic adhesion principles but adds sophisticated layers specifically designed to betray any attempt at removal. It's not just about sticking; it's about communicating integrity. That’s why we, as manufacturers at Shosky Security, focus so much on the specific materials and layer interactions – it's key to the tape's function.
Conclusion
In short, security tape clearly shows if someone tried to open a package. It uses special layers that leave a "VOID" message, making tampering obvious and protecting your valuable goods.
