Security Tape Overview
Security tape also call tamper evident security tape, which is one of the most essential tools for protecting packages during transit.
More than just sealing boxes, security tape acts as a critical layer of tamper protection that alerts both shippers and recipients to unauthorized access attempts.
Security tape helps transform ordinary packages into secure shipments. Whether you’re shipping electronics, pharmaceuticals, or confidential documents, the correct use of security shipping tape ensures your products stay safe from the moment they leave your warehouse until they reach their final destination.
According to the U.S. Department of Homeland Security, implementing tamper-evident packaging like security tape is a best practice for enhancing supply chain security and preventing unauthorized access during transit.
In this guide, you’ll learn how to apply security tape step by step. From choosing the right type of security tape for your packaging materials to placing it correctly across seams and flaps, we’ll walk you through the entire process.
When applied properly, security tape not only secures your goods but also provides visual evidence in the event of tampering.
By following this simple application guide, your packages will benefit from increased protection, reduced risk of theft, and enhanced brand trust. Keep reading to understand how security packing tape can safeguard your shipments and support your business’s reputation.
What is Security Tape?
Security tape is a special kind of adhesive designed to protect packages from being opened without permission. Unlike ordinary tapes, it has features that show if someone has tried to open the package. This tape sticks strongly to boxes and reveals signs like patterns, messages, or designs if tampered with, making any unauthorized access instantly visible.
It’s vital for keeping items safe during shipping and ensuring they reach their destination without being tampered with. Known as tamper-evident, security void, or tamper-proof tape, it helps senders and receivers trust that the contents are secure and untouched. This peace of mind is crucial for valuable, sensitive, or confidential items.
Choosing the Right Security Tape
Selecting the right type of security packing tape for your needs involves more than picking the first option you come across. The effectiveness of the tape depends significantly on its compatibility with the surface it will adhere to, the environmental conditions it will face, and the level of security required. Here’s how to navigate the options to ensure you choose the best security tape for your specific situation:
- Determine what you need the security tape for.
- Make sure the tape works on your box material.
- Consider the weather and where the package goes.
- Check how strong and clear the tape’s security signs are.
- Think about price versus security needs.
Preparation Before Applying Security Tape
Proper preparation of the boxes and surfaces where security tape will be applied is essential to ensure maximum adhesion and effectiveness. Improperly prepared surfaces can lead to inadequate seal strength and compromised tamper-evident features. Here are steps to ensure your packages are ready for secure sealing:
Clean the Surface:
Before applying security tape, ensure the surface of the box is clean, dry, and free from dust, oil, or other contaminants. Use a clean, dry cloth to wipe down the area. For best results, use an alcohol-based cleaner to remove grease or oil, but make sure the surface is completely dry before applying the tape.
Choose the Correct Box Size:
Using a box that is too large or too small can compromise the security of your package. Select a box that fits the contents snugly, with enough room for protective padding if necessary. An overly large box may require more tape and can be easier to tamper with, while a too-small box may burst under pressure, breaking the seal.
Assemble the Box Properly:
Ensure that the box is correctly assembled and that all flaps meet evenly without gaps. A misaligned box can lead to insecure sealing points that are more susceptible to tampering. Use adequate pressure when forming the box to ensure corners and edges are sharp and aligned.
Gather Necessary Tools:
Depending on the type of security tape and the volume of packages, you may need different tools for application. For manual application, a high-quality, dedicated tape dispenser can ensure a consistent and secure application. For higher volumes, consider using a carton sealing machine, which can apply tape more uniformly and quickly.
Plan the Tape Placement:
Decide in advance where the tape will be applied. Typically, the ‘H’ taping method is recommended for sealing boxes securely, where tape is applied along the center seam and across the edge seams of the top and bottom flaps. However, the placement might vary based on the box’s size and the tape’s width.
Test the Tape:
If you’re using a new type of security tape for the first time, apply a small piece to the box material to ensure it adheres well and that the tamper-evident features function as expected. This test can help avoid issues with the main application.
Step-by-Step Guide to Applying Security Tape
Proper application of security tape is critical for ensuring the safety and security of your packages. Follow this guide to maximize the effectiveness of your security measures.
Start with the Center Seam
- Positioning: Begin at the central seam where the box flaps meet. Position the start of the tape 2-3 inches beyond the box’s edge for a stronger seal.
- Application: Lay the tape smoothly along the seam’s center, extending it over the other edge by 2-3 inches to ensure complete coverage.
Apply Pressure for Adhesion
- Smoothing Out: After laying the tape, press down firmly along its entire length. This action secures the adhesive bond to the box and eliminates air pockets that might weaken the seal.
Seal the Edges Using the ‘H’ Method
- Edge Sealing: Apply tape to the box’s side edges, extending from one edge over to the opposite side, ensuring the tape covers both ends of the center seam.
- Wraparound: Make sure the tape wraps around the corners and extends beyond the box’s edges to secure the flaps and add strength to the seal.
Inspect the Tamper-Evident Features
- Verification: After application, lightly test the tape by attempting to lift it to ensure the tamper-evident message or pattern is functioning correctly.
- Security Check: Confirm that tampering with the tape reveals the intended security message or alters its appearance, signaling potential tampering.
Conduct a Thorough Inspection
- Surface Check: Examine the sealed box for any loose ends, unadhered tape, or bubbles that might indicate a compromised seal.
- Integrity Check: Ensure there are no gaps or weak points where the tape doesn’t fully adhere to the box’s surface.
Document the Seal for Reference
- Photographic Evidence: If applicable, especially for valuable shipments, document the sealed package by taking clear photos of the box and tape application.
- Record-keeping: Keep these photos for your records to assist in any future claims or disputes regarding package integrity.
Apply Additional Security Measures if Necessary
- Layering: For high-value or sensitive items, consider applying additional strips of security tape at various angles to reinforce security.
- Reinforcement: Extra tape can deter tampering and provide an additional layer of security.
Perform Final Checks
- Overall Inspection: Do a final walk-through to ensure every part of the box is securely sealed.
- Tamper-proofing: Verify that accessing the box contents would require breaking the seal, leaving clear evidence of tampering.
Signs of Tampering
Identifying signs of tampering is crucial to ensure the security of your packages. Here’s how you can recognize if your security tape has been compromised:
Visible Messages or Patterns:
The most obvious sign of tampering is the visibility of any hidden messages or patterns that appear when the tape is peeled away. Security tapes often have a ‘VOID’ message or a distinctive pattern that emerges to indicate that the package has been opened or tampered with.
Tape Disruption:
Check for any disruptions in the tape’s continuity. This could include tears, cuts, or areas where the tape appears to have been lifted and resealed. Even small discrepancies can be a sign of tampering, as thieves can try to access the box’s contents with minimal disruption to the tape.
Residue Differences:
Look for inconsistencies in adhesive residue. If the tape has been removed, there may be less adhesive on the box than expected, or the adhesive might appear smeared or manipulated.
Tape Condition:
Examine the condition of the tape for any signs of aging, such as discoloration or brittleness, which could indicate that the tape was tampered with some time ago. New tape applied over old tape might also be a sign of tampering, as perpetrators may try to cover their tracks.
Alignment Issues:
Check the alignment of the tape, especially if you used a methodical approach like the ‘H’ sealing method. Misalignment might suggest that the tape was removed and reapplied.
Serial Numbers and Seals:
If your security tape includes serial numbers or seals, verify their integrity and consistency. Mismatched or missing serial numbers can be a clear indication of tampering.
Sound and Texture:
When pressing or handling the tape, pay attention to the sound and texture. Security tapes often have a unique texture and sound when pressed or removed, differing significantly from regular tapes.
Inspect the Entire Package:
Beyond the tape itself, inspect the entire package for any other signs of unauthorized access, such as puncture holes, indentations, or re-taped areas.
Common Mistakes to Avoid
When securing your packages with security tape, certain common mistakes can compromise the integrity of the sealing process. Avoiding these pitfalls is essential to ensure the highest level of protection:
- Insufficient Tape: Using too little tape can make the package easy to tamper with. Ensure you’re covering all necessary areas, especially the box’s seams and edges, and extend the tape beyond the edges for a secure seal.
- Poor Surface Preparation: Failing to properly clean and dry the surface before applying the tape can lead to weak adhesion, making it easier for tamperers to remove the tape without leaving traces. Always start with a clean, dry, and smooth surface.
- Incorrect Tape Application: Applying the tape loosely or with wrinkles can create entry points for tampering. The tape should be applied smoothly and firmly to ensure it adheres well to the surface of the box.
- Overlapping Tape Incorrectly: When overlapping strips of tape, ensure that each piece is pressed firmly against the surface and overlaps adequately with the previous strip. Incorrect overlapping can lead to weak points that are easy to tamper with.
- Not Monitoring Tape Age: Over time, the adhesive on security tape can degrade, especially in harsh environmental conditions. Using old or expired tape can lead to failure in the adhesive properties, reducing the tape’s effectiveness.
- Ignoring Manufacturer’s Instructions: Each security tape can have specific application instructions based on its unique properties. Ignoring these guidelines can lead to ineffective application, so always follow the manufacturer’s instructions for best results.
Best Practices for Using Security Tape in Different Scenarios
Security tapes are not just single-function packaging accessories, but customized “protective barriers” and “compliance certificates” tailored to transportation scenarios and cargo properties.
In fields such as e-commerce logistics, industrial transportation, and cross-border trade, security tapes with different characteristics are addressing core pain points in the entire chain of cargo storage, transshipment, and distribution—including damage, information leakage, contamination, and counterfeiting—by accurately meeting scenario-specific needs. Below are practical applications based on specific scenarios:
I. Sealing Sensitive Document Envelopes
In scenarios such as the circulation of government documents, the transmission of corporate confidential files (e.g., original contracts, financial statements, audit materials), and the delivery of legal documents (e.g., court summonses, notarial papers), the confidentiality and integrity of documents are directly related to information security and the confirmation of rights and responsibilities. Ordinary tapes, with their flaw of being “easy to remove and counterfeit,” often pose significant risks.
In such cases, tamper-proof security packing tapes become the core choice: their surface is printed with irreversible anti-counterfeiting text such as “VOID” or “Opened,” and if an attempt is made to peel them off, the adhesive layer will separate from the envelope surface and leave clear anti-counterfeiting marks—marks that cannot be concealed by re-adhesion.
Some high-end products also incorporate fluorescent fibers or QR code traceability functions; scanning the code allows access to information such as the packer, sealing time, and circulation nodes, preventing the risk of “tape remaining intact but documents being swapped.”
For instance, when a multinational corporation sends financial audit reports across continents, it uses tamper-proof security packing tapes printed with the company’s exclusive logo to seal document envelopes.
Even after 3 transshipment sortings, the anti-counterfeiting status of the tape can confirm that the documents have not been touched—meeting internal compliance requirements while proving the authenticity of the documents to partners.
Additionally, for sensitive document envelopes that need to be opened and closed repeatedly (e.g., private documents temporarily stored in courier lockers), re-sealable security packing tapes can be used.
The adhesive layer uses special pressure-sensitive adhesive, which can be completely peeled off after the first application; the adhesiveness slightly decreases upon re-adhesion but still maintains a seal, and the third peeling will trigger the “Opened” anti-counterfeiting mark.
This design balances the dual needs of “temporary access” and “final tamper-proofing,” making it suitable for scenarios with high-frequency document circulation, such as law firms and government service centers.
II. Anti-Static Tapes: “Electrostatic Firewall”
Electronic products (e.g., chips, circuit boards, displays, precision sensors) are extremely sensitive to static electricity—even weak static electricity (with a voltage exceeding 200V) can break down the internal circuits of components and render the products useless.
During warehouse handling and vehicle transportation, static electricity of several thousand volts can easily be generated due to friction between cargo and packaging, human contact, or poor vehicle grounding. At this point, the core role of anti-static security shipping tapes is to build an “electrostatic dissipation path,” rather than merely serving a fixing function.
In practice, the application of such tapes requires the formation of a “full-wrap protection system”: first, use anti-static security shipping tapes to seal electronic products individually in anti-static bags; the conductive adhesive layer of the tape will form a closed loop with the anti-static coating of the bag, conducting static electricity to the outer packaging through the tape. Second, paste anti-static buffer tapes inside the outer packaging (corrugated cartons) to both fix the bags and prevent bumping and collision, while further dissipating static electricity accumulated inside the cartons.
Finally, use anti-static warning tapes to seal the carton openings; the surface of the tapes is printed with labels such as “Anti-Static Packaging” and “No Friction” to remind logistics personnel to operate in a standardized manner.
For example, when an electronics contract manufacturer transports mobile phone camera modules to clients, it adopts a combined solution of “anti-static film bags + anti-static security shipping tape sealing + anti-static buffer foam + warning tape sealing.” This reduces the static damage rate of products from the original 5.2% to less than 0.3% during over 3,000 kilometers of land transportation, significantly lowering after-sales costs.
It is worth noting that different electronic products require matching anti-static levels: chip-based products need dual-function “anti-static + shielding” tapes (which can block external electromagnetic interference), while ordinary products such as headphones and chargers can use basic anti-static security shipping tapes—balancing protection effectiveness and cost control.
III. Traceable Solid Tapes: A “Full-Link Visual Butler”
Cross-border transportation involves multi-link transshipment (e.g., port loading/unloading, customs inspection, cross-border land transportation) and long-term delivery (usually 7-30 days), making cargo prone to problems such as “difficulty in locating lost goods,” “difficulty in assigning responsibility for damage,” and “false declaration/underreporting.”
Traceable solid security shipping tapes serve as “visual tools” for cross-border logistics through their dual attributes of “physical fixing + data traceability.” These tapes use high-strength solid adhesive as the base material (with strong adhesion and resistance to high/low temperatures, suitable for the humid environment of sea freight and the low-temperature environment of air freight).
The key feature is that ultra-high-frequency RFID chips or NFC tags are embedded in the adhesive layer, which can store cargo information (e.g., product name, quantity, weight, destination, shipper information) and support long-distance batch identification.
In practical applications, its value is reflected in three core links: first, during warehouse sorting, staff scan the tape labels with handheld terminals to verify cargo information within 3 seconds, avoiding “wrong delivery and wrong loading” (especially suitable for scenarios where multiple batches of goods are mixed in containers).
Second, during customs inspection, cargo details can be read by scanning without opening the packaging, reducing packaging damage and delays caused by unpacking inspections. Third, during end delivery, recipients can touch the tape label with their mobile phones via NFC to view the full-link circulation record of the cargo (e.g., which port it stayed at, whether it underwent third-party inspection).
If packaging damage occurs, the responsible link can be traced through the label record. For example, in the “overseas warehouse direct shipping” business of a cross-border e-commerce platform, traceable solid security shipping tapes are used to seal large items such as furniture and home appliances.
After customers place orders, they can view the logistics nodes uploaded by the tape labels in real time. This reduces the cargo loss rate by 60%, improves customs inspection efficiency by 40%, and reduces customer complaints by nearly 30%.
Additionally, for high-value cross-border cargo (e.g., luxury goods, precision instruments), some traceable solid security shipping tapes are integrated with “temperature and humidity sensing” functions.
The labels record temperature and humidity changes during transportation in real time; if the threshold for cargo storage is exceeded (e.g., red wine transportation requires maintaining 12-18°C), an early warning will be automatically triggered to help shippers intervene in a timely manner and avoid cargo devaluation caused by unsuitable environments.
IV. Complete Sealing for Food and Pharmaceuticals
The transportation and packaging of food (e.g., baked pastries, fresh prepared meals, imported dairy products) and pharmaceuticals (e.g., vaccines, oral liquids, sterile medical devices) have a core requirement of “absolute sealing”—it is necessary not only to isolate external dust, moisture, and microbial contamination but also to prevent the volatilization and deterioration of internal components.
At the same time, they must meet compliance standards for food and pharmaceutical packaging in various countries (e.g., China’s Administrative Measures for Pharmaceutical Packaging Materials and Containers, EU Regulation EC 10/2011).
(I) Food Transportation
For food stored at room temperature (e.g., biscuits, nuts), food-grade sterile security packing tapes are used: the tape base material is FDA (U.S. Food and Drug Administration)-certified, free of harmful substances such as plasticizers and heavy metals.
When pasted, it forms a “gap-free seal” with food packaging (e.g., aluminum foil bags, composite film bags), preventing oxidation and moisture caused by air entry. The edges of the tape are printed with “For Food Contact” labels, making it easy for supermarkets and logistics parties to quickly identify compliance.
For example, a bakery uses “aluminum foil bags + sterile security packing tape” to package freshly baked bread; the temperature resistance of the tape can adapt to a 40°C warehouse environment, extending the shelf life of the bread from 3 days to 7 days without any food safety complaints caused by tape contamination.
For fresh food transported in cold chains (e.g., chilled meat, seafood, prepared meals), low-temperature resistant security shipping tapes are required: their adhesive layer maintains strong adhesion even in a low-temperature environment of -20°C to 0°C and will not peel off due to freezing or frost formation.
At the same time, they have puncture resistance and can withstand the pressure generated by the stacking of cold chain boxes, preventing blood leakage and cross-contamination caused by packaging damage.
When a cold chain logistics company delivers seafood for a fresh e-commerce platform, it uses this type of tape to seal the joints between foam boxes and inner fresh-keeping bags. Even after 24 hours of in a -18°C transportation environment, the inside of the boxes remains sealed, and the freshness loss rate of the seafood after thawing is reduced to less than 5%.
(II) Pharmaceutical Transportation
Pharmaceutical packaging has even stricter requirements for tapes—especially for sterile pharmaceuticals such as injections and biological agents, pharmaceutical-grade impermeable security packing tapes must be used: the tape surface is smooth and non-porous, blocking the entry of bacteria and dust, and has good chemical stability, without reacting with pharmaceutical packaging (e.g., outer boxes of glass medicine bottles, pharmaceutical aluminum-plastic panels). Some products are also designed with “easy-tear lines” to facilitate medical staff to quickly open the packaging during use while avoiding debris generated during opening from contaminating the pharmaceuticals.
In the transportation of special pharmaceuticals such as vaccines, tapes need to be linked with the “cold chain traceability system”: the tapes are printed with unique traceability codes; scanning the codes allows access to information such as the vaccine’s batch number, expiration date, and cold chain transportation temperature records, meeting the “full-process traceability” requirements of the national drug regulatory authority. For example, when a biopharmaceutical company transfers COVID-19 vaccines across provinces, it uses pharmaceutical-grade security packing tapes to seal vaccine transportation boxes.
The traceability codes on the tapes are synchronized in real time with the data from the temperature recorders inside the boxes. Regulatory authorities can check at any time through the traceability codes whether the vaccines have deviated from the specified 2-8°C environment during transportation, ensuring the safety and effectiveness of the vaccines.
