As well as competitive polywrapping prices we offer a lot of flexibility; inserting up to 10 items per pack and providing inkjet addressing or carrier sheet printing.

Inkjet addressing or carrier-sheets

The choice is yours depending on your needs and budget

We understand that some mailings are no-frills and inkjet addressing is a fantastic and cost effective option. Our Sitma polywrapping lines have inline inkjet addressing technology that produces high quality print.

For customers that want to include a carrier sheet, we offer black or colour laser printing options that can – if required – print much more than just a name and address.

What can we polywrap?

Most of our polywrapping customers are publishers, but we do handle a variety of mailings; for UK and international delivery. We polywrap some very well-known publications and others that are not so famous, but equally important to us:

  • Magazines
  • Journals
  • Catalogues
  • Direct mail
  • Newspapers
  • Reports

Our customers range from small businesses to media groups with many titles who require a lot of flexibility and capacity as well as competitive prices. We can often handle polywrapping jobs that other suppliers can’t, including larger publications, and jobs requiring selective insertion or cover-mounting.

Our polywrapping service can help you meet your quality and environmental objectives

Our polywrapping services are ISO 9001 and 14001 accredited so you can be confident in our quality standards and in our environmental credentials. Plus these accreditations cover our production planning, maintenance and customer service procedures too, giving you assurance that we have excellent processes in place to ensure mailing schedules are met.


We have a team of people that work on jobs not suitable for machines.

Polybagging by hand is a solution for jobs that cannot be run on the polywrapping line, but where the benefits of polythene are required. We have a team that handle jobs like this, working to ISO 9001 standards and providing an excellent option for:

  • Low volume jobs
  • Jobs using non-machinable polythene
  • Mailings that are not uniform
  • Mailings that are bumpy‘ i.e. contain merchandise that cannot be covermounted

We can supply your polythene

We source polythene and polybags for dozens of customers and get excellent trade rates from our suppliers, so you benefit from lower prices and more.

We can supply all manner of plain and printed polythene, from the lowest cost to the highest quality options. We actively encourage customers to choose biodegrable or recyclable polythene but the choice is yours.
