Envelope Seals

What are the different types envelope seals?

There are 3 different kinds of seals these are: Gummed; Press Seal and Peel & Seal.

Whats the difference between them?

Gummed:

With gummed envelopes they need to be moistened so the gum will stick to the other half of the envelope. When un-moistoined the gum will not adhere to the surface of the envelope. This is the cheapest way of sealing an envelope.

Press Seal:

With press seal you need to fold the flap against the back on the envelope and press to seal. This is more expensive than gummed envelopes but the difference is minimal.

Peel & Seal:

For peel & seal you need to remove a strip to reveal the adhesive, then press to the back of the envelope it is sealed. this is very similar to Press seal but is stronger as the plastic strip keeps the adhesive stickier for longer.

What is the gum made from?

It is made from gum arabic, which is a product of the hardened sap from two different kinds of acacia tree, from West Africa or India.
