Security mailing bags

High security mailing bags & labels

High securityPolybags' range of high security mailing bags and labels provide an extra level of security and integrity for any important delivery.

Covering a range of security solutions - from verifying contents to exposing evidence of tampering - our secure mailing bags provide extra peace of mind for customers until their delivery has reached the intended recipient.

Made from strong but lightweight polythene, all Polybags mailing bags provide a superior postage solution to your standard paper envelope or parcel packaging. Whereas an accidental soaking can destroy a paper-based package, our waterproof polythene mailing bags mean you can be confident that your parcel contents will arrive in one piece.

Tamper evident mailing bags

Extra security for extra peace of mind

Our high security mailing bags offer extra reassurance for any deliveries where attention has to be paid to a variety of security concerns.

Our tamper-evident mailing bags feature a unique tracking code and tear-off receipt to provide customers with a full audit trail of the bag's movement, along with a tamper-evident seal to demonstrate if a bag has been interfered with. Available in opaque or clear polythene, these bags allow identification of contents, when required.

If you need to send a top-secret document, our extra thick security mailers could be just the ticket. Made from tough 360-gauge-thick polythene (90-microns) and featuring a tamper-proof seal, they will ensure your document remains confidential.

At 400-gauge-thick (100-microns) polythene, our black security mailing bags are even thicker and tougher, whilst their opaque black polythene is great for ensuring content confidentiality.

For extra security, you can seal any delivery with one of our security labels which leave a clear 'VOID' message on the bag when opened, providing peace of mind to bag recipients and a clear warning if the bag has been opened suspiciously.
