We are looking for a fixed length, tamper-evident metal strap seal designed specifically for securing high-value shipments. The seal should feature an integrated locking body and strap mechanism, complete with unique serial numbering and our corporate branding for easy tracking. In terms of specifications, the locking head/tag should be made of either polycarbonate or ABS housing, incorporated with a laser-engraved metal plate or a plastic face. The total length should be between 220mm and 240mm, while the strap width is approximately 7mm and thickness around 0.5mm. The product should weigh between 12-15 grams and include unique, non-repeating 6-digit sequential laser-engraved serial numbers.
