Flexographic Print (Flexo)- Printed envelopes – Postage Paid Envelopes

For high volumes of envelopes with minimal print coverage – e.g. PPI, return address and small logo the print is applied in-line flexographically during manufacture.  The printing, die-cutting, gluing and folding are done in one operation on specially manufactured envelope machinery making it very cost effective.

Overprinting  Envelopes – Digital colour envelope printing

For lower volumes printed from one up to four colours ready-made envelopes are overprinted on an offset printing machine.  We use offset machinery specifically designed for printing envelopes.

Lithographic Print (Litho) Colour Printed Envelopes

For high and low volumes with complex print, heavy ink coverage or bleeds the design is printed onto flat sheets which are then die cut, folded and glued in three separate operations.  As the process takes longer and there are more operations the price goes up accordingly.

Manufacturer of envelopes

We order reels of paper so that there is minimal waste during manufacture, the reel width is the size of the face of the envelope plus the size of the side seams.  The reel of paper is loaded onto the envelope machine and threaded through to the delivery table at the end of the process.  There is a splicer attached to the machine so that additional reels are joined automatically negating any requirement to rethread the paper.  The paper is taken via a series of rollers through the following procedures:

Window Envelopes

The desired window size is cut by a flexible foil knife and the waste piece of paper is extracted.  The window film, which has been ordered to the width of the window aperture plus additional film to allow for the glue to be applied, is purchased in reels.  The window film is cut to the required size and glue is applied onto the edges of the window patch which is then stuck over the pre-cut aperture in the paper. The paper then runs through a series of heated dryers to ensure that all of the glue is dry.

Side Seams – the sides of the reel are then cut, folded and glued to form the envelope side seams. The paper then runs through a series of heated dryers to ensure that all of the glue is dry.

Cutting & Folding – a sever then cuts the reel of paper into individual envelopes which forms the flap and throat shape.  The envelope are staggered and gum is applied to the flap.  The envelopes run through a series of dryers to ensure that all of the gum is dry.  The flaps are then folded down.

Final Delivery & Quality Inspection – there is an automatic counter which is set as required and the complete envelopes are delivered onto a table where they are packed into boxes and palletised. Inspections are carried out throughout the process by the staffs setting and operating the machines and by a team of quality inspectors.

Printed Envelopes

Both internal (opaque/internal message to show through window) and external print requirements are applied via polymer printing plates.  The paper then runs through a series of heated dryers to ensure that all of the ink is dry.
