Envelope Enclosing

Envelope Enclosing and Insertion services, from small runs to bulk mailing

We offer bespoke and traditional envelope enclosing and mail insertion. We can insert mail, brochures, documents into envelopes at high speed due to our range of automatic envelope enclosers and machinery. With our high speed machine insertion, we can enclose up to 15,000 items per hour. All sizes including A4, A5 or DL and up to 6 inserts can be machine fed, ensuring maximum efficiency and quality

If your mailing requirements are a little more stringent, or you have particular sizes, shapes, or items to package, then our staff are able to fulfil your campaign by hand, to your exact specifications. Our hand enclosing capabilities are endless and also cover POS and POP collation through to product testing.
