Store your POSTCARDS in our POLY BAGS to protect them from dust, dirt, finger oils and other airborne pollutants. Our bags hold size and thickness tolerances and come in printed outer bags for easy product identification.

We stock postcard bags made out of polyethylene, polypropylene and polyester. All of these materials have passed the Photo Activity Test (P.A.T.) certifying that they are safe for long-term storage.
**NEW** we've added more sizes of sleeves for fold-out postcard packs. These sleeves are for displaying postcard packs with the packs opened to show all cards.
