B&R #25G Glassine Paper 20 Yard Rolls - Protective Interleaf for Art

In this review the B&R #25G Glassine Paper 20 Yard Rolls is evaluated as a practical protective interleaf for artists, conservators, and photographers who need a lightweight, transparent barrier. The bottom line: this roll is best for preserving and separating delicate works on paper, prints, watercolors and pastel pieces because it is natural white, acid-free, and thin enough to prevent smudging without adding bulk. Our review notes its museum-restoration pedigree and that it is not suitable for oil or acrylic paintings.

Key Features

• Lightweight and transparent: The thin, 25 lb. glassine lets artworks remain visible while providing a nonabrasive protective layer that prevents smudging and surface contact.
• Acid-free, natural white: The neutral pH helps protect paper-based work from long-term degradation and discoloration when used as an interleaf or wrapping material.
• Large roll size: At 60 in by 20 yards per roll, it covers oversized pieces and reduces the need for seams or multiple sheets when protecting large prints or works on paper.
• Museum and restoration use: The paper is specified for document preservation and conservator tasks, making it appropriate for archival handling and storage.
• Paint-resistant surface: Customers report that paint and pastels do not stick to the surface, preserving delicate media during handling and transport.

Who It's For

The B&R #25G Glassine Paper is ideal for artists who work in dry media such as pencil, charcoal, pastel, prints, and watercolors, and for conservators or photographers who need a reliable interleaf for storage. Its large roll format and transparency make it particularly useful in studios or workshops that handle large-scale works and need a neutral, nonreactive separator.

Those who should look elsewhere include painters working primarily in oil or acrylic, since the manufacturer does not recommend it for those media, and anyone who needs a heavy duty or textured interleaf for rigid support rather than just surface protection.

Pros & Cons

Pros

• Excellent protection for delicate paper work while remaining transparent and unobtrusive.
• Acid-free construction supports long-term preservation and archival storage.

Cons

• Not recommended for oil or acrylic paintings, so it is not universal for all studio uses.
• Being very lightweight, it offers limited physical cushioning compared with heavier interleaving materials.
