Envelope liners can be produced to a number of different specifications.
They can be offset, letterpress, foil stamped or thermographly printed, on a great variety of papers.
Liners can also be produced using colored papers, which require no additional printing.
Liners can be provided affixed to the envelopes or unattached, for you to attach.

With the number of variables and opions, envelope liners need to be quoted on a custom basis.

Below are links to envelope liner dies, based upon our present envelope liner die inventory.
