With a 57 lb basis weight and self-opening SOS design, these Bulwark bags deliver uncompromising strength for heavy-duty use. The 7-1/16" × 4-1/2" × 13-3/4" dimensions make them ideal for multi-item deli orders, family-sized meals, larger bakery combinations, and mixed takeout packages. The rectangular base stands upright automatically for professional presentation—perfect for restaurants, delis, catering services, and food trucks throughout Delaware and Maryland.
Extra Heavy-Duty 57 lb Basis Weight – Zero Tolerance for Failure
The Duro Bulwark 12# bag features a 57 lb basis weight—engineered for the toughest food service demands. This premium thickness means absolutely no torn seams, no splitting, no bag failure—even with heavy, dense items or multiple orders packed together. Whether bagging hot deli platters, multiple sandwiches, bulk baked goods, or mixed takeout, the Bulwark construction handles everything without compromise. The thick kraft paper resists humidity and grease, maintaining structural integrity in the busiest, hottest food service environments.
Self-Opening SOS Design for High-Volume Packing
The self-opening side (SOS) gusset expands automatically with every item—no hand-holding required even for large orders. The rectangular base allows the bag to stand upright on its own during rapid packing and checkout, creating a professional, organized appearance even during peak lunch or dinner rushes. Staff can pack faster and more efficiently, reducing register friction and improving the customer experience when handling larger orders.
Kraft Virgin Paper – Built for Sustainability & Brand Positioning
Made from kraft virgin paper and 100% recyclable, the Duro Bulwark 12# bag communicates environmental responsibility to customers. The natural brown color is professional, premium, and ideal for custom logo stamping or branded printing. Every bag makes an impression—customers feel the quality immediately, and your commitment to sustainability becomes visible with every takeout transaction, building lasting brand loyalty.
