Security seals for pouches & sacks


When you’re running a business, we here at Slingsby understand that security is essential. Whether you’re delivering cash to the bank or sending large quantities of mail out to customers and clients, you need to ensure it is protected at all times so that potentially important information cannot be compromised.

This is why we offer a varied selection of security seals for pouches and sacks, which give you plenty of choice when you need to seal up a delivery.

Our M numbered security seals provide tamper evident protection for mailing pouches and are simply snapped into place to seal the package. They can then be broken when it needs to be opened. What is more, the seals are numbered to run consecutively, while they are sold in packs of 1,000.

Alternatively, you may prefer our bag seals, which also come in packs of 1,000 and include a tearline for easy removal. They can be used on cash bags, roll cages and tote boxes.

If none of these appeal, we also offer silk seals and post grips, meaning you can always find the right seal for the job at Slingsby.
