Common questions
How many times can these envelopes be reused?
The durable string-and-button closure system supports 20+ reuses per envelope, significantly reducing per-use costs compared to disposable alternatives. This makes them ideal for cost-conscious facilities with consistent interdepartmental routing needs.
What information is pre-printed on these envelopes?
Each envelope displays 5 columns (Date, Deliver To, Department, Sent By, Department) with space for 31 routing entries printed on one side. This eliminates manual labeling and ensures consistent, audit-compliant documentation of internal mail circulation.
Why choose blue for inter-department envelopes?
Blue color-coding enables quick visual identification and special handling prioritization at a glance. This accelerates mailroom sorting speeds and reduces misrouting errors, particularly valuable in high-volume operations managing multiple document types simultaneously.
What size documents fit in 10 x 13" envelopes?
The 10 x 13" format accommodates standard letter-size documents (8.5 x 11"), legal-size documents (8.5 x 14"), and smaller internal reports. This versatile sizing handles most interdepartmental routing needs without requiring multiple envelope SKUs.
