Product Description

Looking for small parcel corrugated cardboard envelopes to maximise the Royal Mail small parcel size limit of 450 x 350 x 160mm? 

The Lil F5 small parcel flatpacks are A3 in size and commonly used for delivering artwork, maps, pictures, frames and lots of other big, flat items through the postal system.  The Lil F5 small parcel flatpacks are 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, they are all 100% recyclable and FSC certified / PEFC approved.

Royal Mail small parcel cardboard envelope maximiser for cheaper postal tariff mailings.  We have extensively researched the flatpack range to get the snuggest fit for your products.  The F5 small parcel flatpack will therefore help to decrease your postage costs by achieving the lowest possible mailing tariff.

The Lil F5 small parcel cardboard envelopes are the stiffest envelopes known to man!

If you're using stiffeners, void-fill or airbags in your packaging, the Lil F5 flatpack is a better way to package what you're sending.

Our Flatpacks are fast to pack because release paper overhangs the hot melt peel and seal flap on this stiff mailer.  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 towards the most appropriate solutions.  It's about delivering unrivalled service.  Over 98% of our orders are dispatched within 24 hours.
