We offer customized Grade 4 tamper-evident bag sealing tapes to meet the specific design and product requirements of our customers. Clients can opt for tailored security bag sealing tapes to ensure synchronization with their secure bag printing. Additionally, we provide various types of silicone release liners and colors, allowing for semi-cutting or perforation based on customer needs, facilitating easier peeling of the liner to expose the adhesive. All products are manufactured in-house, providing cost-effective security solutions at competitive prices.

The security features include the generation of VOID OPEN after peeling, water-soluble printing where the printed text disappears upon contact with solvents or water, positioning of thermochromic ink between the film and adhesive, optional colors for different release liner liners, pre-designed temperature indication information that changes color when heated, and the option to semi-cut or customize the size of the release liner padding.

Specifications include polyethylene film, 25-micron film thickness, red or custom colors, smooth finish, hot melt adhesive, 25# PET release liner padding, and more.

Product Description

This anti-counterfeit bag sealing tape is made of PET film coated with solvent-based adhesive, designed for packaging anti-counterfeit bags. The tape features hidden information imprinted on it, which remains invisible until the sealing tape is torn off. Once removed from the packaging, the anti-counterfeit bag sealing tape film splits into two sections, revealing the concealed information and leaving clear evidence of tampering.

Structure of the anti-counterfeit bag sealing tape: 25-micron polyester film with basic color and hidden information imprinted on one side, and adhesive coated on the other side, separated by a 25-micron release liner.

Features of the anti-counterfeit bag sealing tape: Upon tearing off, the hidden information becomes immediately visible, preventing unauthorized opening, alteration, and theft of the product, thus safeguarding customer privacy.

Applications: This anti-counterfeit bag sealing tape can be used for courier bags, duty-free bags, cash bags, evidence bags, and finds widespread use in various fields such as banking, logistics, courier services, and healthcare.

Advantages: Packaging with anti-counterfeit bag sealing tape enhances the security of items, preventing theft and providing better protection for your goods and valuable assets during transportation.

Convenient to use: Affix the anti-counterfeit bag sealing tape to LDPE bags, press firmly or wait for at least 1 minute. The tape can then be torn off from the surface, and the anti-counterfeit tape film will break into two parts, revealing the hidden VOID information. If not pressed, refrain from immediate tearing.
