Pressure Seal forms are the most secure method of sending business to business or business to client communications through the postal service.

Typically used for secure applications such as payroll, invoices, statements and other secure documents, pressure seal is a laser compatible form which has an encapsulated cohesive glue around the perimeter of the form, that when folded and passed under the pressure rollers of a pressure sealing machine form a strong secure tamperproof bond.

With pressure seal there is no need for envelopes and you can be assured that your mail piece is very secure.


Pressure seal for payroll is the most common use for this medium and has been around since the early 1990’s – Developed by Moore Paragon and Xerox as a way of sending a secure document through the mail without the need for an envelope.

Soft Seal Applications

Soft Seal is a new innovate product that has been designed by GDS and aimed at direct mail as a one piece clean mail solution. The special cohesive is virtually invisible to see and has been designed to be robust enough to be either posted out through normal mail or hand delivered.

 Once the recipient receives the form it can be easily peeled apart without leaving any residue or marks on the message unlike the current methods of hot or cold gluing solutions that can leave a latex residue or even rip the form. It is supplied currently in a C Fold format and can either be preprinted, blank or as a hybrid piece with a free text area for the customer to add a message.

It is produced on 100gsm laser compatible paper and can go through any type of laser printer without issue and to enable the form to be folded and sealed it is the passed through a standard pressure seal machine.


Soft Seal Direct Mail Solutions

Soft Seal for Direct Mail is one of the fastest growing areas with Global Document Systems.

Why outsource this when you can design it yourself and once its does you can even print on a PPI logo (Licenced from the Post Office) and out of the door it goes. You are in total control.
