Custom Tamper Evident Stickers

This material adheres well to smooth, non-porous surfaces such as metal, glass, plastic, and painted finishes. It’s ideal for electronics, machinery, product packaging, and anything requiring security labeling.

Tamper-evident vinyl fractures into small pieces when peeled away, preventing clean removal or reuse. This breakaway behavior ensures the sticker can’t be reapplied or removed without showing clear signs of tampering.

The material is rated for short-term outdoor use up to 1 year. It performs best in indoor or controlled environments where sticker integrity and tamper detection are more important than long-term exposure.

No, tamper-evident vinyl is not laminated. The material must remain uncoated to maintain its breakaway function. Adding a laminate would prevent the sticker from fragmenting as intended.

Tamper-evident stickers are often used for warranty protection, security seals, asset tracking, and calibration records. You can create custom versions using our tamper-evident sticker builder.

At Carstickers.com, we measure and price all our stickers based on square inches. To calculate the square inches of a sticker, simply multiply the width by the height. For example, a sticker that is 4'W x 4'H (4 inches wide and 4 inches high) and a sticker that is 2'W x 8'H (2 inches wide and 8 inches high) will cost the same because both are 16 square inches.

These measurements are based on the widest and tallest areas of the sticker's shape, measured from left to right and top to bottom in a straight line.

Please note: The measurements are taken when the design is upright and in the same position as it will be applied. This ensures that the sticker you order will fit in the intended space. For example, while a diamond-shaped sticker could theoretically be rotated 45 degrees and measured as a square, a 3'x3' diamond and a 3'x3' square rotated 45 degrees are not the same size and will not fit in the same space.

Tamper-evident stickers are made from tamper-evident vinyl, a 5.0 mil thick specialty film that breaks apart when removed. It’s designed to provide visual evidence of tampering and is commonly used for warranty labels, asset tags, and security applications.
