We offer two styles, transparent and opaque, and can tailor them to your specific specifications. This includes tamper-evident level, barcode and serial numbers, unique custom printed logos, as well as a variety of bag styles.

ECO Tamper Evident bags are primarily made of low-density polyethylene material, which is 100% recyclable and environmentally friendly. Their design incorporates various security features to provide top-level security. All tamper-evident bags have a tamper-evident level of 4 and can detect intrusion by heat, freon, and water. Additionally, they can be customized according to any size requirements and artistic designs, including logos, writing boards, custom text, serial numbers, and barcodes.

Characteristics of the anti-counterfeiting bag seal: Once the seal of the anti-counterfeiting bag is peeled off, hidden information immediately appears, preventing the product from being opened, altered, and stolen, thus protecting customer privacy.

Advantages: Sealing packaging with anti-counterfeiting bags can enhance the security of items, prevent theft, and better protect your goods and valuable property during transportation.

Convenient to use: Attach the anti-counterfeiting bag seal to the packaging bag, press it down to adhere, and wait for more than 1 minute. The anti-counterfeiting bag seal will break into two pieces, and the VOID word will be faintly visible.

The bag includes a sealing tape at the opening, featuring one-time use and non-recoverable anti-counterfeit properties. Once opened, hidden text or patterns appear, leaving clear evidence of tampering. Widely used in e-commerce, logistics, banking, education, elections, and judicial institutions, these bags serve various purposes such as tax-free bags, cash bags, election bags, evidence bags, and more.
