Quick Answer: Tamper evident security packaging tapes are pressure-sensitive security materials designed to show visible evidence when a carton, parcel or mailer is opened. For buyers, the first question is not tape color but where the VOID or OPENED evidence must appear after removal.
Choose by security effect: Full-transfer tape leaves clear transfer evidence on the package. Partial-transfer tape divides the evidence between the package and the removed tape. Non-transfer tape reveals the message mainly on the removed tape with relatively low visible transfer. Fiber-tear is another possible response when package-surface damage is accepted.
Match the actual packaging surface: Recycled corrugated cartons, coated paperboard and PE or PP mailers can require different adhesive and security constructions. Buyers should confirm residue tolerance, tape width, roll format, printing or serialization, application equipment and the intended tamper response before bulk production.
For packaging converters and B2B buyers: Review Hanksec tamper-evident security tape options or request material sample testing using your actual packaging substrate and application requirements.
What Are Tamper Evident Security Packaging Tapes?
Tamper evident security packaging tape is a package-closing material designed to make unauthorized opening visibly detectable. Unlike ordinary packing tape, which is primarily intended to hold a package closed, security tape contains a functional layer or material system that changes when removal is attempted.
The security effect can take several forms. A hidden VOID or OPENED message may transfer to the package surface, part of the security pattern may remain on both tape and substrate, the message may appear mainly on the removed tape, or the package surface itself may tear. The correct mechanism depends on the package, required residue level and inspection method.
Tamper evidence should not be confused with product authentication. A security tape can show that a package closure has been disturbed, but the tape alone does not prove that the product inside is genuine. Where authentication or traceability is also required, the tape can be combined with serial numbers, barcodes, QR codes, holographic features or other controlled security elements.
How Tamper Evident Security Packaging Tapes Work
The security response comes from the interaction of the backing, functional security layers, pressure-sensitive adhesive and final packaging surface. When peeling force is applied, the material is engineered to fail or separate in a controlled way instead of behaving like ordinary packing tape.
A typical opening sequence is:
- The adhesive develops sufficient contact with the packaging substrate.
- The tape is lifted or peeled during an opening attempt.
- Peeling stress reaches the functional security or release layer.
- The designed transfer, separation or tear mechanism activates.
- A visible VOID, OPENED, residue pattern, split image or package-surface damage remains.
- The original unopened appearance cannot be restored without visible evidence.
Final performance depends on more than the hidden message. Surface energy, carton coating, corrugate quality, dust, printing varnish, adhesive wet-out, dwell time, temperature, application pressure and removal angle can all affect the visible result.
For a deeper explanation of how functional layers, adhesives and controlled separation work together, see the Security Label Material Systems Guide.
Typical Security Packaging Tape Construction
Security packaging tape is a multilayer material system. The exact construction varies by product and application, but several functional elements are commonly involved.
Film Backing
BOPP is commonly used for carton-sealing and packaging applications because it provides efficient roll handling and general packaging performance. PET is often selected where dimensional stability, precise VOID pattern control or more stable security-layer performance is required. Specialty PE-based constructions may be used where greater flexibility or conformability is needed.
BOPP is itself an oriented polypropylene film, so backing selection should be based on the required tape construction rather than treating “BOPP” and “PP” as completely unrelated material families.
Printable or Protective Surface
The tape surface may include printing, a protective top layer or a printable coating depending on the final design. Logos, warnings, instructions, serial numbers, barcodes and QR codes may be added when required, but print durability and readability should be checked under the actual handling conditions.
Security Release or Transfer Layer
This functional layer determines how the hidden message or transfer pattern appears during removal. Its registration and separation balance must remain consistent across the usable roll so that the opening evidence is repeatable rather than patchy or incomplete.
Pressure-Sensitive Adhesive
The adhesive must match the packaging substrate and the intended security effect. Recycled corrugate, varnished cartons, coated board, PE, PP, PET, metal and glass can require different adhesive characteristics.
The strongest possible adhesive is not automatically the best choice. The target is a controlled security response with reliable package bonding, not uncontrolled fiber damage, coating failure or excessive residue unless those effects are specifically required.
Release Construction
Not every security packaging tape uses a separate release liner. Some single-sided tape constructions are self-wound and rely on a controlled release surface, while linered or double-sided constructions may use paper or film release liners. The correct design depends on the tape architecture and application equipment.
Full, Partial and Non-Transfer VOID Tape: Quick Comparison
Transfer behavior describes where the visible evidence appears after opening. It is not a security-level ranking. A full-transfer tape is not automatically “more secure” than a partial- or non-transfer construction; suitability depends on the package, residue requirement and inspection method.
| Tape Type | Opening Response | Evidence on Package | Typical Selection Direction |
|---|---|---|---|
| Full-Transfer VOID Tape | The security message and transfer layer remain strongly visible on the package after removal. | High / obvious residue or transfer pattern | Shipping cartons, electronics, high-visibility package-integrity applications |
| Partial-Transfer VOID Tape | Part of the tamper evidence remains on the package and part remains on the tape. | Moderate / split evidence | Applications requiring visible tamper evidence with a more balanced surface appearance |
| Non-Transfer VOID Tape | The hidden message appears mainly on the removed tape. | Low or limited visible transfer, depending on construction | Premium packaging, reusable surfaces and applications where the package should remain relatively clean |
| Fiber-Tear / Surface-Destructive Response | The package surface or carton fibers tear when removal is attempted. | Physical package damage | Selected carton applications where fiber tear is intentionally accepted as the tamper indicator |
The package surface still decides the final result. A tape that gives a clear transfer pattern on a smooth coated carton may behave differently on dusty recycled corrugate, highly varnished board or a flexible plastic mailer. Actual-package testing is therefore necessary before bulk approval.

How to Select the Right Tamper Evident Security Packaging Tape
Security tape selection should start with the real package and opening requirement, not with tape color or a preferred VOID message. Buyers should define where the tamper evidence must appear, how much residue is acceptable and how the tape will be applied before choosing the material construction.
1. Define the Required Tamper Response
Decide whether the package should show strong transferred evidence, split evidence on both tape and package, a relatively clean non-transfer effect or physical fiber tear. This decision should be based on inspection requirements and package appearance after authorized opening.
2. Identify the Packaging Surface
Confirm whether the tape will be applied to recycled corrugated board, virgin corrugate, coated or varnished cartons, plastic mailers, PE, PP, PET, metal, glass or another surface. Surface energy, roughness, dust, varnish, recycled fiber content and coating chemistry can materially change adhesion and opening behavior.
3. Define the Residue Requirement
“Low residue” is not automatically better. Strong residue can be desirable when the package itself should retain obvious evidence of entry. Low-residue or non-transfer constructions may be more suitable when package appearance must be preserved after authorized opening.
4. Confirm Application Method
Manual application, handheld dispensers, semi-automatic equipment and automatic case sealers place different demands on the tape. Roll width, core size, roll diameter, unwind force, backing stiffness, winding quality and application pressure can influence machine performance.
5. Evaluate Environmental Conditions
Temperature, humidity, condensation, cold storage, heat exposure, dust and transportation conditions can influence adhesive bonding and the final security response. Environmental limits should be confirmed for the selected construction rather than treated as one universal specification for all security tapes.
6. Define Traceability and Printing Needs
If the tape requires serial numbers, barcodes, QR codes, warning text, logos or other printed information, the printing method and data-management requirements should be defined before production. Variable data must remain readable after printing, slitting, rewinding, storage and application.
Selection Matrix for B2B Buyers
| Buyer Requirement | Starting Direction | What Must Still Be Validated |
|---|---|---|
| Strong visible evidence on shipping carton | Full-transfer VOID tape | Adhesion, carton coating, residue clarity and fiber interaction |
| Evidence on both tape and package | Partial-transfer construction | Transfer balance and package appearance |
| Package should remain relatively clean | Non-transfer / low-transfer construction | Message activation and actual residue level |
| Recycled or rough corrugated board | Project-specific high-contact adhesive direction | Surface dust, fiber strength, wet-out, edge lifting and opening response |
| PE / PP plastic mailer | Low-surface-energy adhesive direction | Bond build, edge lifting and tamper response on the actual film |
| Automatic case sealing | Machine-compatible roll construction | Unwind, core, roll diameter, application pressure and line speed |
| Serialized logistics control | Printed / variable-data security tape | Code readability, data sequence, print durability and roll order |
Packaging Surface & Adhesive Compatibility
Adhesive selection is one of the most important parts of security tape qualification. The same backing and VOID construction can produce very different results when applied to different packaging surfaces.
Corrugated Cartons
Corrugated packaging varies widely. Recycled content, dust, board porosity, surface sizing, printed inks, varnishes and coatings can all influence adhesion. A result obtained on a clean laboratory carton should not automatically be assumed to represent the production package.
For carton-specific tape selection, including VOID transfer type, application position and sealing requirements, see Hanksec’s Security Tape for Boxes selection guide.
Coated and Varnished Cartons
Gloss coatings, aqueous coatings, UV varnishes and laminated surfaces can reduce or change adhesive contact. The coating itself may fail before the tape security mechanism activates, so testing should evaluate both adhesion and the visible opening response.
If security tape releases cleanly, lifts the carton coating or produces an incomplete VOID pattern, the failure point should be identified before changing adhesives. See Hanksec’s Security Tape Failure on Coated Cartons troubleshooting guide for five possible causes and practical testing steps.
PE and PP Packaging Films
PE and PP are lower-surface-energy materials and often require more specialized adhesive constructions than paperboard or clean metal. Flexible bags and mailers also deform during peeling, which can change how the VOID or transfer effect appears.
Metal, Glass and Rigid Plastics
Smooth rigid surfaces can provide favorable conditions for controlled adhesive contact, but coatings, oil, mold-release agents, condensation and surface treatments still need to be considered. For reusable equipment or premium surfaces, residue level should be defined before material selection.
For a deeper substrate-focused discussion, see the Tamper Evident Label Adhesive Guide.
Printing, Customization & Traceability Options
A security tape program should be specified as a material system, not simply as “printed VOID tape.” Customization can affect identification, brand recognition, logistics control, application method and the final tamper response.
| Customization Area | Typical Options | Why It Matters |
|---|---|---|
| Visible color / appearance | Silver, gold, blue, red, black, white, yellow, green, orange, transparent, holographic or project-specific color | Brand fit, visibility and package recognition |
| Hidden message | VOID, VOID OPEN, OPENED, SECURITY, custom text, logo or pattern | Defines the visible tamper message after opening |
| Residue behavior | Full transfer, partial transfer, non-transfer or project-specific response | Controls where evidence remains after opening |
| Printing | Logos, warnings, instructions and controlled graphics | Supports branding and handling communication |
| Variable data | Serial numbers, barcodes, QR codes and sequential identification | Supports traceability, package identification and returns control |
| Application features | Perforation, tear initiation, custom roll length or project-specific converting | Supports handling, opening and application workflow |
For projects requiring serialized identification, Hanksec also supplies perforated security tape with serial numbers, barcodes and QR codes.
Customization should be approved together with the security construction. Heavy ink coverage, protective coatings, perforation or other converting changes can affect stiffness, unwind, print durability or tamper response and should therefore be included in pre-production testing.
Roll Formats, Application & Machine Compatibility
Finished security tape must be compatible with the buyer’s real application method. A construction that performs well during careful manual application may not automatically run correctly on a high-speed case-sealing line.
Before production, confirm:
- Tape width
- Roll length
- Core specification
- Maximum acceptable roll diameter
- Winding direction
- Unwind force
- Backing stiffness and conformability
- Application pressure
- Manual, semi-automatic or automatic application method
- Required perforation or tear-initiation features
Some security tape constructions can be engineered for automatic or semi-automatic case sealing, while others are better suited to controlled manual application. Machine compatibility should be established through production-equipment trials rather than assumed from roll dimensions alone.
Buyers looking for standard or customized finished formats can review Hanksec’s Tamper Evident Security Tape options.
Manufacturing & Quality Control for Security Packaging Tape
Consistent tamper evidence depends on controlled manufacturing across the full web. Printing a VOID message onto adhesive film is not enough. Backing quality, functional coating, security-layer registration, adhesive coating, slitting, winding and final package response must remain stable from roll to roll and batch to batch.
Typical Manufacturing Stages
- Backing-film preparation
- Surface treatment, printing or protective coating where required
- Security release or transfer-layer formation
- Pressure-sensitive adhesive coating or lamination
- Drying, curing or material stabilization as required by the construction
- Slitting and rewinding
- Printing or variable-data converting where applicable
- Final inspection and package-application testing
Quality-Control Checkpoints
| Quality-Control Item | What Should Be Checked | Typical Failure if Poorly Controlled |
|---|---|---|
| Coating Uniformity | Consistent functional and adhesive coating across the web | Uneven transfer or inconsistent adhesion |
| Security Pattern Registration | Alignment and clarity of the hidden message | Broken letters, patchy VOID effect or unclear opening evidence |
| Adhesive Consistency | Tack and peel behavior across the roll and production lot | Edge lifting, weak bonding or excessive residue variation |
| Transfer Response | Approved full-, partial- or non-transfer effect on the representative package | Opening result differs from the approved sample |
| Slitting & Edge Quality | Width, clean edges, winding and roll geometry | Curling, telescoping or application problems |
| Printing / Variable Data | Ink adhesion, code readability and sequence accuracy | Smearing, unreadable codes or traceability errors |
| Roll Unwind | Consistent release during manual or machine dispensing | Machine interruption or inconsistent application pressure |
| Batch Repeatability | Comparison with an approved reference sample | Different tamper response between production lots |
For more information about peel adhesion, release force, die-cutting performance, VOID activation and printing checks, see the Hanksec Security Label Material Quality Control Guide. Security tape approval should also include the final opening response on the actual packaging substrate.
For pressure-sensitive tape adhesion evaluation, methods such as ASTM D3330/D3330M may be referenced where appropriate. Peel testing can support controlled quality evaluation, but it should not be treated as a complete security-tape approval because the final opening response also depends on the package substrate, dwell condition and functional security layers.
Hanksec recommends retaining approved reference samples for customized projects and comparing production batches against the agreed opening effect, adhesion, printing result and roll performance.
Where Are Tamper Evident Security Packaging Tapes Used?
Security packaging tapes are used where a package needs visible evidence of unauthorized opening during storage, transportation, delivery, returns handling or controlled access.
| Application | Typical Packaging | Main Security Requirement |
|---|---|---|
| E-commerce & Logistics | Shipping cartons, parcels and selected mailers | Visible opening evidence, returns control and package identification |
| Electronics & High-Value Goods | Printed cartons, export boxes and equipment packaging | Detect unnoticed opening and resealing attempts |
| Pharmaceutical & Healthcare Projects | Medicine cartons and transport packaging | Package-integrity indication as part of a validated packaging system |
| Confidential Documents | Envelopes, document boxes and controlled mailers | Visible evidence if the closure has been opened |
| Cosmetics & Premium Packaging | Coated and decorative cartons | Tamper evidence with controlled residue and surface appearance |
| Security Bags | Courier bags, cash bags, evidence bags and confidential bags | Specialized bag-sealing constructions and controlled opening evidence |
Security-bag projects often use different linered or double-sided sealing structures from ordinary carton-sealing tape. They should therefore be evaluated separately. For those applications, see Hanksec’s Security Bag Tape Solutions.
Tamper Evident Security Tape vs Standard Packing Tape
| Feature | Tamper Evident Security Tape | Standard Packing Tape |
|---|---|---|
| Primary function | Package closure plus visible evidence of opening | Package closure |
| Functional security layer | Yes, depending on construction | Normally no |
| Removal result | VOID, OPENED, residue, split image, tear or other designed response | Usually no designed security response |
| Traceability options | Can include controlled printing, serial numbers, barcodes or QR codes | Possible printing, but not inherently a security function |
| Qualification requirement | Package, adhesive, tamper response and application method should be tested together | Primarily closure and handling performance |
Security tape should be selected when the buyer needs evidence that the package closure has been disturbed. Standard packing tape remains appropriate when the requirement is only package closure and handling.
What Security Tape Can and Cannot Do
Tamper evidence, product authentication and regulatory compliance are related but different objectives.
- Tamper evidence: indicates that the package closure may have been opened or manipulated.
- Authentication: helps verify whether the product, label or package is genuine.
- Traceability: connects a package or tape segment with controlled identification data.
- Regulatory compliance: depends on the complete packaging system and the requirements that apply to the product and market.
A VOID message by itself does not prove product authenticity. When authentication or traceability is required, the tape may be combined with serialized data, barcodes, QR codes, holographic features or other controlled security technologies.
Regulated Packaging Considerations
Tamper evident security tape should not be described as automatically compliant with pharmaceutical or other regulated-packaging requirements. Compliance depends on the complete packaging system, product category, intended market and applicable rules.
For certain over-the-counter drug products in the United States, FDA tamper-resistant packaging requirements focus on visible evidence of entry within the complete package system. A specific tape technology by itself does not establish compliance.
In the European Union, Commission Delegated Regulation (EU) 2016/161 addresses safety features including an anti-tampering device for covered medicinal products, but it does not prescribe one universal VOID tape construction.
For regulated applications, the complete tape-and-package system should be validated against the requirements that apply to the product and destination market.

Frequently Asked Questions
What are tamper evident security packaging tapes?
They are pressure-sensitive package-closing tapes designed to create visible evidence when the closure is opened or the tape is removed. Depending on the construction, the tape may reveal a VOID or OPENED message, transfer residue, split the security image or create another irreversible change.
What is the difference between standard packing tape and tamper evident security tape?
Standard packing tape mainly provides package closure. Tamper evident security tape adds a functional security mechanism that changes when removal is attempted so the package can show evidence of opening.
What is the difference between full-transfer, partial-transfer and non-transfer VOID tape?
Full-transfer tape leaves strong visible evidence on the applied surface. Partial-transfer tape divides the evidence between the tape and package. Non-transfer tape reveals the message mainly on the removed tape while keeping the application surface relatively clean, depending on the actual construction and substrate.
Which packaging surfaces can security tape be applied to?
Security tape can be developed for corrugated cartons, coated board, PE, PP, PET, metal, glass and other packaging surfaces. Because coating, roughness, recycled fiber, surface energy and contamination affect adhesion, testing on the actual package is recommended before bulk production.
Can security tape include serial numbers, barcodes and QR codes?
Yes. Depending on the project, security tapes can include sequential serial numbers, barcodes, QR codes, logos, warnings, colors, perforation and custom VOID or OPENED messages. Print durability and data readability should be verified before production approval.
Can tamper evident security tape run on automatic case sealers?
Some constructions can be designed for automatic or semi-automatic case sealing, while others are better suited to controlled manual application. Machine trials should confirm unwind force, core and roll dimensions, backing stiffness, application pressure and line compatibility.
Does security tape always leave residue?
No. Residue behavior depends on the construction. Full-transfer designs intentionally leave strong evidence on the package, partial-transfer designs divide the evidence, and non-transfer constructions are intended to keep the package relatively clean while showing the message mainly on the removed tape.
Does tamper evident security tape automatically meet pharmaceutical packaging regulations?
No. A security tape is only one component of the complete packaging system. Regulatory suitability depends on the product, package design, intended market and applicable requirements, and should be validated before commercial use.
What should a buyer provide when requesting security tape samples?
Provide the packaging substrate, required tamper response, residue preference, tape width, application method, storage or transport environment, printing or traceability needs and estimated quantity. A representative carton, film or packaging sample can improve material-selection accuracy.
Request Security Tape Testing & Technical Recommendation
Reliable security-tape performance depends on the interaction between the backing, functional security layers, adhesive, package surface, roll construction and application method. A tape approved on one carton or plastic film should not automatically be approved for another package.
For a faster recommendation, send Hanksec your packaging substrate, required transfer behavior, residue requirement, tape width, application method, storage environment and any serial-number, barcode or QR-code requirements.
Hanksec can recommend a suitable security tape direction and prepare samples for adhesion, opening-response and application qualification before bulk production.
