MWPO - What does MWPO stand for?

Definition of MWPO:

The Label Planet code assigned to our range of matt white polyolefin labels. These labels are made of a white polyolefin film with a matt finish and have a permanent marine quality adhesive (BS5609 standard). They are suitable for use with laser printers or inkjet printers and belong to our range of waterproof labels. Polyolefin is a thin, durable, and highly flexible material, which makes it ideal for indoor or outdoor applications where a label must be waterproof and/or able to adhere onto curved or uneven surfaces or unusual materials.
