Pull-tight seals are a type of security seal used to provide tamper-evident protection for a wide range of applications. They are widely used in industries such as transportation, logistics, and retail, where they are used to secure bags, boxes, and containers. Pull-tight seals are made of durable materials such as plastic or metal and can be easily tightened by hand, but require tools to remove, making them tamper-evident. They are ideal for use in situations where a visual indication of tampering is required, such as in the food and pharmaceutical industries. Pull-tight seals can also be customised with unique serial numbers, barcodes, or company logos for added security and traceability.
