Double Lock – Two-Part Plastic Drum Seal

The Double Lock is a two-part plastic drum seal designed to provide secure, tamper-evident protection for HDPE drums used in pharmaceuticals and chemicals. Built with a polycarbonate (PC) stick and a polypropylene (PP) body, it combines the strength of PC with the flexibility and resilience of PP.

Once engaged, the seal cannot be removed without visible damage, ensuring clear evidence of tampering and maintaining product integrity.
