Definition: Tamper-evident tape is a type of tape that has special adhesive properties and is designed to leave noticeable marks or traces when it is peeled off, torn, or tampered with, indicating that the item has been opened or tampered with.
Material: Tamper-evident tape is typically made from materials like polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC), which are durable and have good abrasion resistance, tear strength, and UV resistance. The tape surface is coated with a special tamper-evident adhesive that changes when the tape is removed.
Design Features: The design of tamper-evident tape typically includes special security labels, such as VOID text, warning icons, or hidden information, which become clearly visible when the tape is removed, alerting users that the item has been opened or tampered with.
Chemical Properties:
Adhesion: Tamper-evident tape has a strong adhesive backing that ensures it sticks securely to various surfaces, such as cardboard, plastic, metal, glass, etc. When an attempt is made to peel it off, the adhesive leaves specific marks, ensuring that any unauthorized opening will leave traces.
Tamper-Evident Functionality: The main feature of tamper-evident tape is its tamper-evident function. Once the tape is peeled off or removed, the original surface is damaged or altered, and it cannot be restored to its original state, ensuring that the item has not been tampered with or replaced.
Durability: The tape has excellent weather resistance, UV resistance, and high-temperature resistance, making it suitable for various environmental conditions.
Technical Specifications
Advantages:
Strong Tamper-Evident Protection: The tape’s tamper-evident functionality ensures that the packaging cannot be opened without leaving clear marks (such as the word “VOID”), indicating tampering.
High Visibility: Tamper-evident tape is usually made in bright colors and clear warning labels, making it highly visible and easy to identify in various environments.
Ease of Use: Tamper-evident tape is easy to use, requiring no additional tools. Simply apply it to the packaging surface, and it can be easily removed and replaced if necessary.
Strong Durability: The tape is made of high-strength materials, ensuring excellent wear resistance and durability. It is suitable for use in various environments and under physical stress.
Cost-Effective: Compared to traditional safety seals or complex tamper-proof systems, tamper-evident tape is a cost-effective solution that is easy to apply and replace.
Safety and Precautions:
Non-Toxic: Tamper-evident tape is usually made from non-toxic, environmentally friendly materials, meeting safety standards for use in various industries.
Storage Conditions: The tape should be stored in a dry, cool place, away from high temperatures or moisture, to maintain its adhesive properties and performance.
Surface Application: Ensure the surface is clean and smooth for proper adhesion of the tape. Avoid excessive stretching or damage to the tape during application.
