Bags Unlimited has been in the Collection Protection business since 1976. We are the forerunners in the
Collection Protection business and are the #1choice of collectors for storage, display, and shipping products for their collectibles.

Archival Polyester (Mylar) is an inert material of the highest purity and clarity. Our polyester film is approved by The Library of Congress for the indefinite care of paper products (hundreds of years). Polyester (Mylar) will not discolor, damage or adhere to items placed inside it. It is a sturdy film that will give extra support to fragile documents. We use DuPont inert Melinex® or a suitable equivalent.

We offer Polyester in the following configurations: Standard Sleeves – 2 mil and 4 mil  |  L-Sleeves – 4 mil  |  Sheets – 4 mil.  |  ‘Folder’ Sleeves – 4 mil (sealed on one line side).

Since we are the manufacturers, we can make custom sizes at low minimums. Call 800-767-2247 or email for a quote.

Our Super Archival Backing Boards are sized perfectly to fit in our polyester sleeves. This material meets the Library of Congress archival standards. It is 100% alpha cellulose, .040 “thick, acid-free (alkaline pH 8.5), lignin-free, contaminant-free. It comes buffered with a 3% calcium carbonate buffer. Use for indefinite storage (hundreds and hundreds of years).

Archival Storage Boxes are available in 3 configurations: Drop-front boxes, which allow for easy retrieval of stored items, Clamshell design, and a storage box for rolled items. They come in 3 material specifications as well: .060″ thick, Blue-Gray Perma/Dur® buffered board outside; heavy, white, lignin-free bond paper inside that has a pH of 8.5. Drop front on the long dimension of the box, TAN Acid-Free Boxes are made from .060″ thick, solid-core, lignin free cellulose fibers that are buffered and have a pH of about 8.5. Drop front on the long dimension of the box allows for easy print removal. Boxes come assembled and have metal-edged, reinforced corners for superior stacking strength, and Archival BLACK Museum Grade Photo and Print Storage Boxes are 60-point, acid-free, scuff resistant and buffered with a 3% calcium carbonate buffer. The interior is lined with a white paper that measures a pH of about 8.5. The boxes have metal-edged corners and ship assembled.

Whether you’re shipping your maps flat, folded or rolled, we have an excellent selection of sturdy mailers. For most mailers, we also have reinforcing cardboard backings that fit into the mailers for extra strength and corner and edge protection for your valuable collection while in transit.
