How to Pack and Seal Do Not Bend Envelopes Correctly
Pack and seal your do not bend envelopes correctly for damage-free delivery every time.
Preparing contents
Quick answer
Wrap contents in protective material, slide into the envelope with the board backing behind the item, press out excess air, and seal firmly along the full length of the peel-and-seal strip. Contents should fit with 5-10mm clearance but not rattle loose. The board backing should face the back of the envelope so it supports the contents against bending from the rear.

Sealing securely
Partial removal can leave unsealed sections.
Run your finger or a roller along the seal to ensure complete adhesion.
Adhesive begins losing tack once exposed to air.
Trapped air creates a pillow effect that can stress the seal during transit.
