Honeycomb is paper cushion. Bubble is film cushion. The bench should know which line it signed off. This page stays with board-back envelopes.
Packaging Suppliers keeps Board-back envelopes apart from a folded mailer. Board-back envelopes are a separate list from plain envelopes and from mailing bags.
What this collects
A board-back envelope keeps a document flat.
The notes below stay on board-back envelopes. A mailer folds. That is acceptable for a tee shirt and wrong for a certificate or a photo that must not crease.
Before the order goes in
Pick the envelope from the document size, not from the nearest mailer.
On Packaging Suppliers, put Board-back envelopes on the order with the lines it belongs to, so you are not paying a second delivery for the piece you forgot. Free UK delivery starts over £50 ex VAT.
