These brown, carton envelopes
feature tamper evident locking flaps, which once inserted cannot be opened without causing considerable damage to the cardboard envelope. For extra security, double seal the envelopes
with one of our packaging tapes. Each mailer
is manufactured from 350 gsm micro-flute corrugated board which helps maintain the structure and rigidity of the envelope.
This board keeps your products flat and free from creasing during posting and will protect from day to day wear and tear. Reinforced corners also provide extra protection for your products.
The expandable edges allow the cardboard envelope to increase in height by up to 40 mm, meaning that you can use these cardboard envelopes
to post a variety of different products including, DVDs, CDs, books, catalogues and calendars.
