Corri-Cor® - MK4

Designed to eliminate the health issues associated with MDF. The Corri-Cor® product is the original corrugated backing and is the only one on the market which contains all the original features. MK4 is produced to the same specification as our Archival WR with the addition of a kraft finish on the back to give a more natural wood finish to the back of the frame. The archival double corrugated board is made of 100% virgin fibre throughout including the flutes. It conforms to the DIN ISO 9706 standard for permanency and is lignin free, acid free and pH neutral with no optical brighteners. The trademark Britannia Mounts Corri-Cor® bowing in the board helps to keep artwork flat. The water-resistant coating (WR) on the reverse helps to prevent moisture getting into the back of the frame. No barrier board is required.Use in conjunction with Crescent self - adhesive frame sealing tape (brown) with aluminium backer.
