KEY FEATURES OF THE 11x17 SIDE-LOAD SLEEVE

• 3.94 Mil Extra Heavyweight: Over 30% thicker than standard sleeves, providing a rigid feel that prevents document creasing.
• Side-Loading Security: Designed for long-term archiving. Because the opening is on the binder-ring side, your heavy 17" sheets are physically locked in and can never slide out while carrying or flipping through the binder.
• Archival Safe & Acid-Free: 100% Polypropylene. Will not lift ink or toner from blueprints or yellow your records over time.
• Landscape Orientation: Specifically designed for 17x11 documents, fitting perfectly in landscape-format 3-ring binders.
• Crystal Clear Finish: Glass-clear polished poly ensures that fine lines on architectural drawings remain sharp and readable.
• Reinforced Binding Edge: Standard 3-hole punch configuration (4-1/4" center-to-center) to fit all standard 11x17 horizontal binders.
