Envelope Flap Sealing Methods

Lick and Stick: Requires application of moisture to close.

Peel and Seal: Peel off plastic liner to expose glue strip, fold over and press to close.

Self Seal: Pre-gummed bottom flap for ease of closure, no moisture or plastic liner required.

Do you require your contents to be Secretive?

Secretive envelopes have a printed internal pattern that prevents the contents in the envelope from being read through the envelope when held up against light. Non-Secretive envelopes are manufactured using unprinted envelope paper that does not have a printed pattern inside.

What are Window Faced or Plain Faced envelopes?

Plain face: No window to display the address on document enclosed.

Window face: Has a clear window on the front. Recommended for mail merge applications.

Australia Post - Does your item qualify as a letter?

To be considered a letter, your item must:

✔  Weigh less than 500g

✔  Contain flexible items

✔  Have a rectangular shape

✔  Be no larger than a B4 envelope

✔  Be no thicker than 20mm

If your item were bigger than this they will classify it as a small or large parcel. Letters should not contain stiff objects such as bottle tops, pens, items enclosed in a hard case, and so on. High-speed letter sorting equipment could damage such objects, or the objects could damage other articles.
