20x20cm Square MDF Sheet: 3mm Flat Sublimation Blank Pack of 5

Match your custom projects to the rest of your product range with our square MDF sheet sublimation 20x20cm blank. This flat MDF sheet is 3mm thick with a fully sublimatable front surface and a plain MDF reverse. Unlike the A3, A4, and A5 sheets, which follow paper sizing, this sheet matches the 20x20cm craft-standard format already used across our square MDF coaster, square glass coaster, square MDF clock, and square MDF puzzle range. Sold as a pack of 5, it is the natural raw material for custom-cut pieces that need to sit alongside existing product dimensions. Always remove the plastic film before pressing.

Why 20x20cm Is the Craft-Standard Size That Connects This Sheet to the Rest of the Range

The A3, A4, and A5 sheets are sized by paper convention. The 20x20cm square MDF sheet follows a different logic entirely. This dimension already appears throughout our catalogue: the square MDF coaster, the square glass coasters, the square MDF clock, and the round and square MDF puzzles all share this footprint. That consistency means a crafter cutting custom shapes from this sheet can design pieces that sit naturally alongside an existing product line. A custom-cut insert, a matching coaster variant, or a one-off design that needs to fit the same footprint as a stocked product all become straightforward with this blank. Press a unique design, cut it down, and it slots into the same packaging, display, or product category as items already in the range. The pack of 5 makes it practical to produce a small custom batch without overcommitting to a larger sheet size.

Press Settings for the 20x20cm Square MDF Sheet

Always remove the plastic film from each square MDF sheet before pressing. Press at 200°C for 60 seconds on a flat heat press with firm, even pressure. Use a protective sheet between the platen and the coated surface. Allow each sheet to cool fully before cutting, mounting, or further handling.
