Sealing a black envelope is similar to sealing any other envelope, utilizing various methods based on the type of envelope and desired finish. You can seal a black envelope using moisture, adhesives, special envelope features, or decorative elements like wax seals.
Here are several effective ways to seal a black envelope:
Methods for Sealing Black Envelopes
The method you choose depends on the envelope's design and your personal preference for security or style.
1. Using Moisture
Many envelopes have a gummed flap that activates with moisture. This is a classic and straightforward method.
- Using a Sponge:
- This is a pretty simple and effective way that anybody can use.
- Slightly dampen a small sponge.
- Lightly run the sponge along the gummed strip on the back flap of the envelope.
- Fold the flap down and press firmly to seal. Be careful not to use too much water, as this can cause the paper to wrinkle or the gum to dissolve completely.
- Cotton Swab/Bud:
- Similar to using a sponge, a cotton swab (or bud) can be used for more precise application of moisture.
- Dampen the tip of a cotton swab.
- Carefully trace the gummed line on the envelope flap.
- Fold the flap and press to seal. This method is good for controlling the amount of moisture.
2. Using Adhesives
If the envelope doesn't have a gummed flap, or you need extra security, external adhesives work well.
- Using a Glue Stick:
- Apply a thin, even layer of a standard glue stick along the edge of the envelope flap.
- Fold the flap down immediately and press firmly across the glued area.
- Ensure the glue is applied close to the edge for a complete seal.
- Sellotape or Self Adhesive Labels:
- Clear sellotape (packing tape or standard clear tape) can be used across the flap to secure it to the envelope body.
- Alternatively, self-adhesive labels, stickers, or custom seals can be placed across the flap closure for both security and decoration. This is especially effective on black envelopes where a contrasting label can stand out.
3. Using Special Envelope Features
Some envelopes come with built-in sealing mechanisms.
- Using a Self-Seal or Peel and Seal Envelope:
- These envelopes have adhesive strips on both the flap and the envelope body.
- For "peel and seal," simply remove the protective strip from one of the adhesive lines.
- Fold the flap down so the two adhesive lines meet.
- Press firmly along the flap to create a strong seal. These are quick and require no external tools or moisture.
4. Using a Wax Seal
For a decorative and traditional finish, especially suitable for invitations or special correspondence in a black envelope, a wax seal is an excellent choice.
- Using a Wax Seal:
- Melt sealing wax (available in sticks or beads) using a wax melting spoon or glue gun designed for wax.
- Drip a small pool of melted wax onto the envelope flap, directly over the closure line.
- Quickly press a sealing stamp (often with an initial, monogram, or design) into the hot wax.
- Hold the stamp in place for a few seconds as the wax cools and hardens.
- Gently lift the stamp to reveal the impression. Wax seals add a touch of elegance and security.
Summary of Sealing Methods
Here's a quick overview of the methods:
| Method | Description | Tools Required |
|---|---|---|
| Moisture | Activates gummed adhesive on flap | Sponge, Cotton Swab |
| Glue Stick | Applies external adhesive | Glue Stick |
| Tape/Labels | Secures flap with external adhesive | Sellotape, Labels |
| Self/Peel and Seal | Uses built-in adhesive strips | None |
| Wax Seal | Decorative and secure seal using melted wax | Sealing wax, Stamp |
Choose the method that best suits the envelope type and the occasion. All these methods are effective for sealing a black envelope.
