Tamper Evident Bags – What Makes Ours Different?



Tamper evident bags are made from high quality and durable polythene. Tamper evident bags are simply designed to protect important contents such as cash and confidential documents. The use of a tamper evident glue line is designed to highlight if the polythene bag has been tampered with through a variety of different methods such as:

  • Freezing
  • Heating
  • Forced Entry
  • Water

Platinum Standard Security Seal

Our Tamper Evident Bags are market leading with the use of a ‘platinum’ standard security seal. Our security bags give piece of mind as they are produced in accordance with ISO 9001: 2008 Standard Accreditation.


The platinum protection that our security bags offer means they are the market leaders for tamper evident protection. We use tri-extruded super tuff polythene films in the manufacture of our tamper evident bags which protects against the risk of tearing or ripping.



Tamper Evident Bags are usually produced to an opaque standard to prevent seeing confidential or secure contents. Our Tamper Evident Bags are produced with thickens of between 80 and 120 micron. Combined with printing, this produces a truly unique opaque finish, enhancing the security and confidentiality of the security bag.



With over 40 years of development experience, our technical team excel in producing some of the best performing materials in the market. We were the first company to produce a peel and seal closure for mailing bags which demonstrates our continued commitment to the innovation of our products.

Our subsidiary, also offers a wide range of tamper evident bags.



Each Tamper Evident Bag has a ‘tear off receipt’ which can be used to help in the audit trail of important documents and other secure items such as cash or evidence.

We maintain records that allow full traceability of any envelope back through the production processes to its raw material constituents allowing full traceability of each tamper evident bag.
