Product Description

F3 large letter corrugated cardboard envelopes - great for shipping illustrations, paintings, A4 brochures, calendars and DVD's.

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 stiff and flat item postage - the Lil F3 flatpacks are the best large letter cardboard envelopes, providing heavy duty packaging for delivering A4 brochures, calendars, DVD's, photos, photo frames, diaries, journals, arts & crafts and more through the postal system. The F3 is made from high density 150gsm 'Kraft' e-flute corrugated board; very stiff, tough stuff. Every single flatpack in our range uses our leading hot melt peel'n'seal / tear-strip system for easy sealing and easy opening.Tough packaging doesn't get better than this!

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 it arrives. 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 to the most appropriate solutions. It's about delivering unrivalled service. Over 98% of our orders are dispatched within 24 hours.
