Our crystal clear bags are a great option for protecting your artwork. Popular with artists, photographers and collectors, these bags will accommodate a double mat plus 3/16” foamcore. Our bags are made from inert and acid free OPP plastic and come with a top flap with a re-sealable adhesive strip on it allowing it to be folded over and sealed over the bag's opening. It's as easy as inserting an item, peeling the adhesive cover strip, and then folding and pressing the flap to the bag to seal it. The flap seal allows for items to be smaller than the height of the bag as the flap seal can be folded past the opening of the bag if needed. 18 7/16 x 24 1/4 for 18x24 artwork. Bulk pack of 100 bags.
