Product Description

F3 large letter flatpacks 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!

If you're using stiffeners, void-fill or airbags in your packaging, the Lil F3 flatpack is a better way to package what you're sending.  The Lil F3 is the stiffest envelope known to man!

Our tough large letter flatpacks are fast to pack because release paper overhangs the hot melt peel and seal flap.  The hot melt adhesive peel and seal closure provides the best seal (at least twice the strength of standard double sided-tape).

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


Your packaging is the first time that your customers physically experience your product.  Getting it right is your chance to make the best first impression; we help you do just that.

With a clear understanding of what you need, we use our knowledge and expertise to guide you towards the most appropriate solutions.  It's about delivering unrivaled service.  Over 98% of our orders are dispatched within 24 hours.
