Tamper Evident Label Material
Tamper Evident Label Material

Tamper Evident Label Material is specially designed to provide clear evidence of unauthorized access or tampering. Once removed, the label leaves behind a visible “VOID” or destructed pattern on the surface, preventing reuse and ensuring product authenticity. Widely used in electronics, pharmaceuticals, logistics, and high-value goods packaging.

Tamper Evident Label
Tamper Evident Label

Tamper Evident Labels are pre-designed security labels made from high-performance materials. They deliver immediate visual proof of tampering through patterns, text, or irreversible damage when removed. Easy to apply, customizable in size, color, and printing, they are ideal for securing packaging, warranty seals, and confidential documents.

Security Tape
Security Tape

Security Tape offers a strong adhesive bond combined with tamper-evident features. Once peeled, it reveals hidden messages such as “OPEN VOID,” ensuring the package cannot be resealed without detection. Suitable for cartons, pallets, and logistics shipments, it enhances supply chain security while maintaining durability in transport.

Security Bag
Security Bag

Security Bags are specially manufactured with tamper-evident closures that indicate unauthorized opening. Made from durable multi-layer plastic film, they provide high resistance to tearing and manipulation. Commonly used in banking, cash-in-transit, forensic evidence, and confidential document handling to ensure contents remain intact from sender to recipient.

Destructible Label
Destructible Label

Destructible Labels are designed to break apart into tiny fragments when removal is attempted, making them impossible to transfer or reuse. They are widely applied for warranty protection, asset tracking, and brand security, ensuring that once applied, they cannot be removed without leaving clear damage. 

Water-sensitive Label

Water-sensitive Labels change color when exposed to water or moisture. This unique feature makes them an effective tool for detecting water damage, leakage, or product misuse. Often used in electronics, logistics, and warranty protection for high-value goods.
