Mylar Corners

Mylar Corners

Definition: Mylar corners are small, flexible pockets made from Mylar film used to secure the corners of paper-based artwork to a backing board or mat without applying adhesives directly to the artwork itself.

Overview

These corners provide a reversible and archival-safe method for mounting or displaying artwork, prints, photographs, or documents. By holding the artwork at its corners, Mylar corners minimize stress on the paper and reduce the risk of damage.

Characteristics

• Material: Made from Mylar, a clear polyester film that is strong, chemically inert, and stable over time.
• Flexibility: Easily slips over the corners of artwork, conforming to different thicknesses without tearing.
• Archival Quality: pH-neutral and safe for long-term contact with paper-based materials.
• Transparency: Allows the artwork to remain fully visible while secured.

Uses in Art and Framing

• Securing individual corners of prints, photographs, or documents to mat boards.
• Temporary mounting for exhibitions or handling without adhesive contact.
• Part of archival storage systems to prevent movement or abrasion of stored artworks.
• Used in combination with hinging tape or Mulberry paper for additional stabilization.

Best Practices

• Ensure that the corners of the artwork are clean and free of debris before inserting Mylar corners.
• Select corners sized appropriately for the thickness of the paper or board.
• Use with acid-free backing boards to maintain archival safety.
• Combine with other reversible mounting techniques, such as hinging or P90 tape, for added support when necessary.
