How to use

Place the document inside the envelope so that edges are aligned and contents lie flat. Remove the protective backing from the peel-and-seal adhesive strip, fold the flap down and press firmly along the closure to secure the seal. For thicker inserts, ensure the flap folds without straining the adhesive; press along the full length of the flap to improve adhesion. Store unopened packs in a dry, cool place to maintain adhesive performance.

Usage recommendations

For mailing important documents, use a single envelope per item and avoid overfilling; if additional protection is needed, consider inserting paperboard or using a padded mailer. When preparing bulk mailings, test one envelope first to confirm fit and sealing, then proceed with batch sealing to maintain consistency.
