• Plain white paper wrap is an economical, easy switch to paper wrap. The main delivery details are then just ink jetted in black on the mailing line
• Remember the flat size of the paper mailing pack still needs to fall within the maximum RM size categories
  For example:
  Category - Large Letter, Machine readable:
  Maximum size is 345 x 245 x 10mm
• Paper wrap can be different types of paper, plain and printed. Discuss which is the most secure option for your pack
• Paper wrap can be printed litho or digital, depending on the amount of personalisation required or format of product
  Watch your ink coverage on the design of your paper wrap if printing digitally as digital ink is expensive
  Special colours and coatings may be applied to your paper wrap
• Your mailing provider may have their own postal rates to share with you
• Multiple inserts and onserts for extra revenue can be included in the pack. Check the maximum number with your mailing provider
• If you find a printer that can also paper wrap, you will save the delivery costs of your books to a mailing house and the carbon footprint
• Think about using paper wrap with regional/third party advertising for extra revenue. For example, the back cover of the wrap could be a full page, colour advert
• Paper wrap is a different type of paper to your main book. Therefore, if you repeat an image from the book, the colour result will be different
