Postal & Mailing Industry Rubber Bands Guide

February 10, 2026 · BulkRubberBands Team

The postal and mailing industry operates on precision, speed, and reliability. Every day, mail processing facilities, USPS operations, direct mail companies, and shipping centers handle millions of pieces of mail that must be sorted, bundled, and organized with clockwork efficiency. In this high-volume environment, even the smallest components can make or break operational success.

Rubber bands play a critical role in postal and mailing operations, serving as the backbone for mail bundling, sorting processes, and organizational systems. However, not all rubber bands are created equal. The demanding nature of postal work requires bands that can withstand constant handling, maintain consistent elasticity, and provide reliable performance shift after shift. That's where Alliance Rubber Company, America's last remaining rubber band manufacturer, delivers the quality and consistency that postal and mailing professionals demand.

Located in Hot Springs, Arkansas, Alliance Rubber Company has been the trusted choice for postal operations nationwide, providing American-made rubber bands that meet the rigorous standards of the mailing industry. Through BulkRubberBands.com, postal and mailing businesses gain access to direct-from-manufacturer pricing and the reliability that comes from sourcing products made right here in the USA.

How Postal & Mailing Businesses Use Rubber Bands

Rubber bands serve multiple essential functions throughout postal and mailing operations, each requiring specific performance characteristics to ensure smooth workflow and operational efficiency.

Mail Bundling Operations

The most visible application of rubber bands in postal operations is mail bundling. Whether preparing outgoing mail for carrier routes or organizing incoming mail for distribution, rubber bands provide a secure yet easily removable method for keeping mail pieces together. Unlike tape or string, rubber bands can be quickly applied and removed without damaging mail pieces or slowing down processing times. Mail carriers particularly rely on rubber bands to keep route mail organized during delivery, as bands can be easily removed and reused throughout the day.

High-Speed Sorting Operations

Modern mail processing facilities utilize high-speed sorting equipment that requires mail to be properly bundled before and after processing. Rubber bands used in these environments must withstand the mechanical stress of automated handling while maintaining their grip on mail bundles. The bands must be strong enough to keep bundles intact during transport through conveyor systems, yet flexible enough to be removed quickly by postal workers during the next processing stage.

Mail Tray Organization

Mail trays and containers require organization systems that can adapt to varying volumes and mail piece sizes. Rubber bands provide flexible solutions for securing mail within trays, preventing pieces from shifting during transport between processing stations. This application is particularly important for fragile items or priority mail that requires extra care during handling.

Best Rubber Band Sizes for Postal & Mailing

The postal and mailing industry benefits from specific rubber band sizes that match the unique dimensions and requirements of mail processing operations.

Size #117B - The Mail Bundle Standard

The #117B rubber band has become the industry standard for mail bundling operations. Measuring 7 inches in length with a 1/8-inch width, these bands provide the perfect stretch and strength combination for bundling standard mail pieces and packages. The #117B excels in high-volume operations where consistent performance is crucial, making it the preferred choice for USPS facilities and large mail processing centers.

Size #64 - Versatile Mail Sorting

For smaller mail bundles and detailed sorting operations, size #64 rubber bands offer the ideal solution. At 3.5 inches in length, these bands are perfect for organizing mail pieces within trays, securing small package bundles, and handling specialty mail items that require more precise bundling control.

Size #33 - Precision Organization

Size #33 rubber bands provide solutions for the most detailed postal operations. These smaller bands excel in administrative areas, document organization, and specialized sorting tasks where larger bands would be impractical.

Size Length Best Application Volume Recommendation
#117B 7 inches Mail bundle standard High-volume operations
#64 3.5 inches Tray organization Medium-volume sorting
#33 3 inches Precision tasks Administrative use

Special Considerations for Postal & Mailing

Postal and mailing operations present unique challenges that require specialized rubber band characteristics to ensure optimal performance and safety.

High-Volume Durability Standards

Alliance rubber bands are manufactured to withstand the demanding nature of high-volume postal operations. Each band undergoes rigorous quality control testing to ensure consistent elasticity and breaking strength. This attention to quality means fewer band failures during critical operations and reduced downtime caused by equipment jams or bundle failures.

Consistent Sizing for Automated Systems

Modern postal facilities rely heavily on automated processing equipment that requires precise specifications. Alliance rubber bands maintain tight tolerances in sizing and thickness, ensuring compatibility with automated bundling and sorting systems. This consistency reduces equipment maintenance and prevents costly processing delays.

Safety and Regulatory Compliance

Postal operations must adhere to strict safety standards for worker protection and mail security. Alliance rubber bands are manufactured using materials that meet or exceed industry safety requirements, providing peace of mind for facility managers and ensuring compliance with postal regulations.
