How an Open-Ended Envelope is Made

The art of making one involves the processes of folding and sealing. An open-ended envelope has several components that are important to its construction. The components and applications are as follows:
1) Front Panel
This is the face of an envelope with no seams. It can serve as a first impression to users. It is the surface that carries custom designs.
2) Back Panel
This is the rear of an envelope after folding. Contents enter through this side.
3) Side Flaps
This folds to its side seam and forms an envelope’s body.
4) Bottom Flaps
This folds to enclose the bottom side of an envelope.
5) Score
This is a fold line that is close to the seal flaps. It allows it to fold and seal.
6) Throat
This is at the crown of an envelope’s caricature. It measures from a score’s fold line to where the bottom flap is.
7) Shoulders
Shoulders are at the two edges by the throat. This is where a side flap will seal to the top flaps. This design is critical as it determines the comfort of the content’s enclosure and the openings by its sides.
8) Seal Flap
This is the flap that closes envelopes. The designs vary based on the filling process and its application.
9) Seams
This depends on what the use of the envelopes would be. There are two seam types commonly used for open-ended construction. They are:

  • Side Seams
    These are on the envelope’s back panel. They seal the back panel after the folding process. They can be on the right or left side of this panel. This style is best for printing outer envelopes. It enables the printing to align perfectly.
  • Center Seams
    These seams join the side flaps to each other at the focal point of an envelope. By being slightly off this point, adhesive gums can easily seal the seams. These center seams work perfectly for automated insertion materials because they give a maximum opening to the throat and excellent strength to the side seams. They also allow envelopes to carry heavier or thicker contents like a brochure, booklet, or financial statements.

 

10) Gums
To keep contents safe, the closure is properly and carefully sealed using gums or adhesive. These adhesives include:

  • Back Adhesives
    These are permanent gums used for sealing during an envelope’s construction.
  • Re-Moisturized Adhesives
    These are quite common. With moisture, the glue activates and seals the content. It is placed on the flap either as split or full. This type of adhesive can sometimes lose its bonding due to heat. But if stored properly, it will last for a long time. It is made from dextrin and synthetic resin.
  • Peel & Seal
    This is also very common in envelopes. The adhesive has a protective liner that covers it from exposure till its use. It seals without adding moisture.
  • Latex Adhesive
    It also seals without moisture. When pressed onto itself, it quickly bonds.
    The choice of gums depends on their strength and usage. For long -term use, many prefer Latex or peel & seal. You can click here to learn more about these gums.
