54″ x 109″ 20 Mil Poly Replacement Bag With CB-2 Closure Bar.

Poly bags are more costly than vinyl, but offer some significant benefits in use and durability. Poly will remain flexible in almost any temperature where vinyl tends to be a little stiff in cooler temperatures. For large curved work or pieces with a tight radius where confirmation is critical poly is the answer.
