A gummed envelope is a type of envelope that uses a water-activated adhesive, often referred to as "gum," to seal the flap. Unlike self-adhesive envelopes which have a pressure-sensitive adhesive already applied, gummed envelopes require you to moisten the gummed strip before sealing. This older style of envelope is still used in certain situations, offering unique advantages and disadvantages compared to its modern counterparts.
Why Use Gummed Envelopes?
While less common now, gummed envelopes remain relevant for several reasons:
-
Security: The need to wet the gum strip before sealing adds an extra layer of security, making it slightly more difficult to tamper with compared to self-sealing envelopes. This is particularly valuable for sensitive documents or when a tamper-evident seal is desired.
-
Durability: The gummed adhesive, once properly applied, creates a strong and lasting seal. This is especially useful for heavier mail or items that require extra protection during transit.
-
Archival Purposes: For archival purposes, gummed envelopes offer a more durable seal that is less likely to fail over time compared to pressure-sensitive adhesives. This is crucial for preserving important documents.
-
Traditional Aesthetics: Some find the classic look and feel of a gummed envelope to be more elegant or appropriate for certain occasions, such as formal invitations or important correspondence.
-
Cost-Effective (in Bulk): In some cases, particularly when purchasing in bulk, gummed envelopes can be a more cost-effective option compared to self-adhesive envelopes.
How to Use a Gummed Envelope
Using a gummed envelope is straightforward:
-
Prepare the Envelope: Insert your documents or materials into the envelope.
-
Moisten the Gummed Strip: Lightly moisten the gummed strip on the envelope flap using a sponge, wet finger, or a lick (though a damp sponge is generally preferred for hygiene). Avoid over-wetting, which can cause the gum to become too soft or the envelope to become soggy.
-
Seal the Envelope: Firmly press the moistened gummed strip onto the envelope flap, ensuring complete adhesion.
-
Allow to Dry: Allow the sealed envelope to dry completely to ensure a secure and lasting seal.
What are the Different Types of Gummed Envelopes?
While the basic principle remains the same, gummed envelopes come in various sizes, colors, and weights. They can range from standard business sizes to larger formats for documents or packages. Some are also available in different paper weights, offering varying levels of durability.
What are the Alternatives to Gummed Envelopes?
The most common alternative is the self-adhesive envelope. These envelopes have a pressure-sensitive adhesive already applied to the flap, requiring no additional moistening. Other alternatives include envelopes with peel-and-seal closures or those with a tape or sticker seal.
Are Gummed Envelopes Still Used Today?
While self-adhesive envelopes are significantly more common today, gummed envelopes still have their place, particularly in situations where security, durability, or archival qualities are paramount. Their continued use reflects the specific needs and preferences of certain users and industries.
Where Can I Find Gummed Envelopes?
Gummed envelopes can usually be found at office supply stores, online retailers, and some stationery shops. You might need to search specifically for "gummed envelopes" as they aren't as readily displayed as self-adhesive options.
