Envelope Stiffeners / Layer Pads
Incredibly Strong C3 / A3 / C4 / A4 C5 / A5 & C6 / A6 Envelope Stiffeners / Layer Pads.
We also produce 12″ & 7″ square envelope Stiffeners / Layer Pads which are perfect for using with our range of Vinyl Record Mailers.
Our great quality envelope stiffeners are perfect for enhancing the levels of protection of a huge range of items being posted out in envelopes through the mail. They can also prove invaluable in helping reduce surcharges imposed by Royal Mail for T shirts, baby grows or other items of clothing that should be charged as Large Letters but but due to moving in their packaging register as small parcels through Royal Mail automatic volumiser scanners.
If you are experiencing problems with Royal Mail surcharges on your large letters because they incorrectly register as small parcels on their automated parcel sorting machines, we can help.
In addition to a range of stock size stiffeners for envelopes & mailing sacks & mailing bags, we can manufacture custom sizes to help you prevent erroneous Royal Mail surcharges with your large letter mailings.
Please note: envelope stiffeners are often described as envelope strengtheners or envelope fillers.
