Tamper Evident Bags

Tamper evident low density polyethylene (LDPE) security bags for a wide variety of cash and non-cash applications. Minimum LDPE gauge is 30 microns in either transparent or opaque material and finished with standard or bespoke print in up to 6 colours. 

All our products are fully 'close the loop' recyclable, subject to any additional materials such as self-adhesive labels being used.

Single or two trip closures available. Simple to use and to check for signs of tampering. Numerous features possible, including high specification tamper resistant, pressure sensitive adhesive that prevent and deter all known forms of tampering, including heat, cold sprays and liquid attack.

Alternatively low security and no-security adhesive closures can also be supplied. 

The body of the bag can be colour coded for logistical identification purposes, numbered and barcoded as required and include receipt strips, gussets and carry handles, (normally on larger bags for heavier applications). Bags can also have an external pouch for unsecured documentation.

Welded side edges can be microprinted as a defence against slitting and rewelding.
