tamperseals

Tamper seals, also known as tamper-evident seals or tamper-proof seals, are devices or materials applied to closures or packaging to indicate that an attempt has been made to open them. Their primary function is to provide visual evidence of tampering, thereby protecting the integrity of the product inside. These seals are crucial in a variety of industries, including pharmaceuticals, food and beverage, cosmetics, and secure document transport.

Common types of tamper seals include plastic or foil seals that break or tear upon attempted opening, leaving visible evidence of unauthorized access. Some seals are designed to leave behind a specific pattern or message, such as "VOID" or "OPENED," when tampered with. Others may change color or disintegrate. Another category involves shrink bands or sleeves made of heat-shrinkable plastic that are applied around a cap and neck of a bottle or container. When heat is applied, they shrink tightly, creating a seal that will break if the cap is twisted.

The effectiveness of tamper seals relies on their clear and unmistakable indication of compromise. This helps consumers and businesses trust that the product has not been interfered with, ensuring safety and authenticity. They play a significant role in preventing product adulteration, counterfeiting, and theft, offering an important layer of security throughout the supply chain. The selection of a specific tamper seal often depends on the type of packaging, the product's value, and the required level of security.
