Tamper Evident Tape Adhesives
Smart pressure sensitive adhesives for tamper evident tapes
Fortunately, the right self-adhesive tape can help your tamper evident tapes easily meet these requirements. Based on Hot Melt Pressure Sensitive Adhesive (HMPSA), our tamper evident tape adhesives enable converters’ tape to offer:
- Improved package integrity with compatibility with many substrates, including PE and PP films and cardboard
- Strengthened durability through resistance to high and low temperatures
- Heightened security with compatibility to thermographic inks and ability to leave a clear “void” message
- Reduced downtime due to the ability to increase converting line speeds for manual and automated lines
- Increased ease of use due to high peelability

Frequently Asked Question about Tamper Evident Tape Adhesives
What are applications of tamper evident security adhesives?
The tamper evident security adhesives’ application can separate in three types: bags, tapes and label. Tamper evident security tapes adhesives are largely used in luxury bag such as for duty free stories and banker for cash. Tamper evident security bags adhesives provide an anti-temper seal. When the security bag is tampered with, it display a clear "VOID" message on the application bags. When the security bag is opened after, it will be damaged and will be unable to reconstruct the sealing tape to its original condition and leave a warning message (OPENED, VOID, etc.) A new safety seal should be applied in its place; this will give apparent evidence of tampering. Often it is pressure sensitive tape with special tamper resistant or tamper evident features.
Bostik provide hot melt pressure sensitive adhesives with high temperature resistance for your different application in security void tapes and label such as partial transfer security VOID, total transfer tamper evident printing material and no transfer tamper evident.
What is the advantage of using tamper evident security tapes adhesives?
Tamper evident tapes need to display a clear “VOID” message and cannot be resealed after applied on the bags. Bostik’s tamper evident tape adhesives, based on hot Melt Pressure Sensitive Adhesive (HMPSA) offer :
- Proof security by leaving a clear void message and superior sealing protection for your product, brand
- Enhanced bonding performance on specific substrates.
- Low viscosity: improved application process performances for manual and automated lines
- Impossible to re-seal
- Compatibility with eco-friendly material for packaging
- Compatible with biodegradable bag materials
- Resistant to hash temperature (-10°C to 40°C)
For banker (Bags for cash ) :
- Excellent adhesion to low energy surfaces(plastics)
- High internal (cohesion) strength
- Wide range of temperature resistance
What is the problem when the tape is removed cleanly without showing the tamper evident message (OPENED)?
The majority of the security tapes use a high performance adhesive that is suitable for a wide range of low energy surfaces (plastics). The first thing is to check the surface is on the "recommended surfaces" list for the tape. Then the surface temperature must be at or above the minimum application temperature when applied. If the bags are opened without tamper or resealed, there is a risk for the documents that they could be stolen or altered.
Bostik's smart pressure sensitive adhesives for tamper evident tapes provide compatibility with many substrates, including PE and PP films and cardboard (recyclable material). It also has a strengthened durability through resistance to high and low temperatures.
