What is Peel and Seal?

Peel and Seal envelopes come with double-sided tape and liner instead of the remoistable glue on regular envelopes. Therefore, instead of licking or moistening the glue with a damp sponge or brush, the liner is simply peeled off and the envelope can be sealed. This is ideal for applications where there are hygiene concerns, but also simply for convenience and speed in sealing.
