A gummed envelope is a type of envelope that uses a water-activated adhesive, often called gum, to seal the flap. Unlike self-adhesive envelopes, which have a pressure-sensitive adhesive already applied, gummed envelopes require moistening the gum strip before sealing. This traditional method has been used for decades and offers a distinct feel and security compared to its modern counterparts.
Why Use Gummed Envelopes?
While self-sealing envelopes dominate the market today, gummed envelopes still hold a place, particularly in certain applications. Their advantages include:
- Security: The moistening process creates a strong, reliable seal that's more difficult to tamper with than a self-adhesive closure. This makes them a popular choice for sensitive documents or valuable items.
- Durability: The gummed seal tends to be more durable than the adhesive in self-sealing envelopes, especially in extreme temperatures or humidity.
- Professional Appearance: The clean, crisp look of a properly sealed gummed envelope can convey a sense of formality and professionalism, ideal for official correspondence or important documents.
- Cost-Effective (in bulk): Although individual gummed envelopes might seem slightly more expensive, purchasing them in bulk often proves to be more economical compared to self-adhesive alternatives.
How to Use a Gummed Envelope
Using a gummed envelope is a simple process:
- Prepare the Envelope: Ensure your documents are neatly placed inside the envelope.
- Moisten the Gum Strip: Lightly lick the gummed strip along the flap. Avoid excessive wetting, as this can lead to a soggy envelope or damage to the contents. A damp sponge or a wet fingertip can also be used for more controlled application.
- Seal the Envelope: Firmly press the flap down onto the body of the envelope, ensuring full contact with the gummed strip. Hold for a few seconds to ensure a secure seal.
What are the Differences Between Gummed and Self-Adhesive Envelopes?
The main differences lie in the adhesive and application:
| Feature | Gummed Envelope | Self-Adhesive Envelope |
|---|---|---|
| Adhesive | Water-activated gum | Pressure-sensitive adhesive |
| Application | Requires moistening the gum strip | Seals automatically upon pressing the flap down |
| Security | Generally more secure | Less secure; easily opened |
| Durability | More durable in extreme conditions | Less durable in extreme conditions |
| Cost | Can be more cost-effective in bulk purchases | Generally cheaper for single-envelope purchases |
