Pressure Seal

Checks, Forms, & Direct Mail

Pressure seal is the most efficient way to produce mail-ready checks and forms without the need for an envelope. Through a unique folding and sealing process, a pressure sealer converts documents into self mailers. The whole process requires less parts, labor, and lead time to reach the mail stream. Pressure Seal checks and forms are secure and confidential making them a great fit for a variety of applications.

Examples of documents you can mail using pressure seal forms:

  • Checks
  • Utility bills
  • Medical bills
  • Transcripts
  • Tax forms (W-2, 1099, ACA)
  • Notices
  • Invoices
  • Statements
  • PIN information
  • Integrated Cards/Labels
  • Direct Mail

How Does Pressure Seal Work?

First, pressure seal checks are imaged with a laser printer and compatible software. Next, the stub checks are loaded into a pressure sealer feed system (High volume systems run with a laser printer inline to a pressure sealer). During the folding process, the sealer machine aligns patterns of cohesive along the edges of the form. When the folded form passes through a series of sealing rollers that apply pressure, the cohesive is activated, creating a seal. The final product is a sealed mailer that is opened by tearing along the perforations.

Pressure Seal FAQs

Pressure Seal is a system comprised of a one-page self sealing document and/or a folder sealer for sealing the document.
The form is sealed though a process of folding the form on a pressure seal folder/sealer. Folding the form aligns patterns of cohesive which have been pre-applied to the document during manufacturing. Once folded, the document travels through a series of sealing rollers inside the folder/sealer. These rollers apply pressure to the form, which activates the cohesive and in turn creates a secure fiber tear seal.
Unlike a standard adhesive, a cohesive requires two patterns placed on top of each other to create the bond. In the case of a pressure seal cohesive, very high pressure is required to activate the bond.
Proper cohesive chemistry and application of the cohesive to the form are key. Accurate perforation registration ensures proper alignment of the perforations and cohesive pattern during folding. Other important factors are paper type, print quality, packaging and storage.
Product must be kept in its original wrap to ensure proper moisture content of the paper is maintained. Product should be climatized in the imaging environment at least 48 hours prior to imaging. In general, forms should be put through the folder sealer on the same day that they are imaged.
Only specific papers are compatible with Pressure seal technology
Co-hesive patterns are designed for postal/printer considerations and to accommodate forms manufacturing process. Other patterns allow for different ways of opening the sealed document. In general, one may stick with a few of the basic fold and cohesive patterns for a large share of the pressure seal applications. However, there are unique patterns which may offer distinct benefits to the end user.
Normal shelf life is from 6 months to a year with proper packaging and storage. Forms that are left exposed to the air will see a rapid deterioration in sealing performance. Leftover forms should be placed back inside their cartons interior bag until the next use.
Some factors to consider:

  • Faster output of finished mail
  • Cost/Availability of traditional envelopes
  • Inserter lines are slow and more expensive than sealers
  • Conversion Costs
Take into account the duty cycle per month, volume per print run, and seasonal fluctuations. If your application is critical, you may need 2 machines for redundancy in the event of down time. Other considerations are: the length and width of the form, the fold depths, paper basis weight, and ease of use. Choose a well built machine with a heavy duty sealing section that will last. Total weight of the folder/sealer is a good indication of a well built machine.
