The Acme HL Seal is a smooth ribbon, plastic pull-tight seal manufactured from Polypropylene material.


The design profile is unique and features rolled heat staking technology to secure the metal spring insert to the body, thus providing clear evidence of tampering if forced open or cut.


The seal is manufactured with gripping spikes as standard but with an option of a tear off tag if preferred.


The excellent breaking strength, combined with a ribbon width of less than 6mm, makes this seal the perfect choice where the application hole size and strength is the main consideration.
