Protect your photos, prints, and artworks from long-term damage with our White Acid-Free Photo Frame Inserts - a simple yet essential addition to any quality framing setup.
These inserts are cut to standard frame sizes and are made from conservation-grade, acid-free matboard. They act as a barrier between your artwork and the backing board, helping to prevent acid migration and the risk of discolouration, yellowing, or brittleness over time.
Many standard backing boards, including MDF, can become acidic as they age. By pairing these inserts with an acid-free mat board, you help shield your image from contact with potentially damaging materials inside the frame.
Ideal for Float Mounting
These inserts can also be used as a clean, acid-free backing mat for float-mounting items inside a frame. Ideal for shadow box frames or 3D displays, they provide a crisp background surface when mounting artwork, documents, or objects directly on top - without using a traditional window mat. This is a popular method for showcasing pressed flowers, certificates, medals, or handwritten letters with depth and dimension.
Key Features of Acid-Free Frame Inserts
- Acid-Free & Buffered Core – Made from premium conservation-grade matboard, buffered with calcium carbonate for a higher and stable pH to help neutralise acidity over time.
- No Window Opening – Solid, uncut board designed to sit behind your artwork inside the frame.
- Protective Backing Layer – Creates a clean, stable surface between your print and the frame backing.
- Preservation-Ready – Ideal for use with acid-free matboards to create a full archival framing setup.
- Australian Made – Cut and packed in our Sydney workshop using professional equipment and high-grade materials.
Why Use an Acid-Free Insert?
Using an acid-free insert is an easy and affordable way to improve the longevity of any framed image. Pairing one with an acid-free mat board provides full protection - keeping your artwork spaced away from the glass and shielded from acidic materials behind it.
