Our Crystal Clear Archival Bags have a protective adhesive closure strip located on the body of the bag, not the flap. This adhesive placement is important because when the contents are removed or re-inserted there is less chance of the artwork sticking to the adhesive strip. We still recommend that you insert and remove items carefully from these sleeves.

Bags are sized to accommodate a thickness of matted prints or multiple prints. Bags up to 11 x 14" will accommodate 3/16" in thickness, and bags 12 x 16" and larger will accommodate 3/8" thickness. Each bag is sealed on three sides and opens on the short side with a 1-1/2” flap.

If you need measurements in millimeters/centimeters there is a PDF chart under the Resources tab.

• Bags up to 11x14 will accommodate 3/16’’ thickness.

• Bags 12x16 and larger will accommodate 3/8’’ thickness.

• 1.5 mil (BOPP) polypropylene is archival safe for long-term storage.

• Re-sealable adhesive strip just below the opening of the bag instead of on the flap.

• Sealed on 3 sides and opening on short side with 1-1/2" flap.

• All bags are manufactured (+/ -) 1/16" of the size listed.

• BOPP is Biaxially Oriented Polypropylene has excellent clarity, low electrostatic charge and high tensile strength. Corona treatment on both sides.

Measurement Conversion Chart - Inches to Metric

Here is a formula to calculate the size of a bag for storing books and other three dimensional objects. First measure the Width, Length, and Depth (thickness) of your book or item.

Add the Width + Depth of book + 2 inches

Add the Length + Depth of book + 3 inches

Example: Book is 7.25 x 9.25 x 1 inch

7.25 (width) + 1 (depth) + 2 = 10.25 inches

9.25 (length) + 1 (depth) + 3 = 13.25 inches

The flat bag should be at least: 10-1/4 x 13-1/4 inches
