5 Types of Tamper-Evident Labels

Most people have seen the phrase “don’t accept if seal is broken” or something with the same sentiment. The seal being referenced is one fromtamper-evident labels. As you might have learned at your last tech business seminar, they let the consumer know that the product has been accessed without authorization. There are different types of these labels that fit for different product applications. Continue reading to learn 5 of them.

Blister Packs

Blister packs are a pre-formed packaging, in foil and plastic, utilized for small-sized goods or pharmaceuticals. They’re commonly used for products that can be purchased in individual units or dosages like OTC or over-the-counter drugs. They also contain information about the item. Blister packs provide evident proofs that the content is properly sealed and intact before being purchased and used. A damaged foil seal is an easy identifier that the product has been tampered with.

Seal Tapes

Tamper-evident tapes or seal tapes are used to add security to products. They’re used in almost all products, from computers and laptops to packages like pallets and boxes. Seal tapes have words on them, and they leave wordsin the package itself when removed. This provides clear evidence of tampering.

Shrink Bands

Using shrink bands is an inexpensive way of tamper proofing. They’re mostly applied over lids or closures as an indication that the product is safe to be purchased. If the band is removed, it might mean that the product has already been opened. Shrink bands are commonly found on products such as foods and beverages like wine bottles.

Safety Buttons

Along with shrink bands, the food that’s packed in glass containers or mason jars is also sealed with metal bubble-top lids known as safety buttons. These metal lids make a noticeable audio-visual pop when the jar is opened for the first time. Consumers are recommended not to consume a product if there’s no popping sound. This is because the safety feature in the package of the product has already been activated.

Smart Labels

Smart labels use radio-frequency identification or RFID chips under the label stock. These labels provide both high-security and tamper-evident functions. Smart labels give the ability to automatically track and identify the products they’re attached to. The RFID on the labels or ink-coding protects both businesses and consumers from counterfeit items and contaminated products.

The 5 types of tamper-evident labels listed above are used to protect products from being opened or damaged. They serve as an extra barrier to keep the products safe as they journey to consumers. Learn more at your next tech seminar.
