Courier Networks Rapidly Adopt Certified Tamper-Evident Formats
Courier networks pursuing shipment security and damage prevention are increasingly specifying certified tamper-evident postal tubes with documented security-seal testing and crush-resistance certification, rather than the conventional screw-cap tube that dominated the category when tamper-evident tooling costs were less competitive in prior shipping cycles. This shift commands meaningfully higher unit cost than conventional tubes given the enhanced sealing and certification testing involved across most qualified suppliers. Manufacturers report certified tamper-evident orders now outpacing conventional screw-cap orders across several major courier accounts tracked this cycle, a clear reversal from just a few years earlier across the broader sector.
