These Carryout Bags are perfect for matted or framed artwork, oversize maps, prints, and posters. They are available in sturdy 3 mil case-packs or heavy-duty 4 mil bags on rolls. Made from clear polyethylene. When choosing sizes, consider length, width and thickness of items going inside the bag. Allow enough length to fold over. Extra length also allows bag to function as a carry-out bag. Bags do not come with handle holes. Use bags to roll flat posters for take-home safety!
