Product Description

F3 large letter corrugated envelopes are for shipping A4 brochures, calendars and DVDs. These are large letter cardboard envelopes.

If you're using stiffeners, void-fill or airbags in your packaging, there is usually a better way to package what you're sending.  For large envelope postage, the Lil F3 flatpacks are the best large letter cardboard envelopes, providing heavy-duty packaging for delivering A4 brochures, calendars, DVDs, photos, photo frames, diaries, journals, arts & crafts and more through the postal system. 

The F3 is made from 150 gsm 'Kraft' e-flute corrugated board; very stiff, tough stuff.  Every single flatpack in our range uses our leading hot melt peel'n'seal / red tear-strip system for easy sealing and easy opening.  Plus, like all of our postal packaging, they come with green credentials out of the box - 100% recyclable and FSC certified / PEFC approved.  Tough packaging doesn't get better than this!

Safe in transit, but easy to open when they arrive. This really is tamper proof packaging.
