Flexo printing is the most cost-effective solution available for high-volume printing of envelopes that have a straightforward design and specification.
Flexo printing uses a polymer-based plate to print the envelope design directly onto the paper reel before the envelope is made.
Flexo is:
best suited to print runs of 50,000 envelopes and upwards
ideal for large volume, simple designs such as business reply envelopes (BREs) and PPI envelopes
able to print 1 to 4 colour, giving you as much flexibility as is possible with this printing technique
