Poly envelopes are crafted from durable engineered plastic that can withstand various environmental conditions. The tough material stops liquids from reaching your papers and resists natural wear. Poly envelopes are a safe mailing option and can be reused as protective coverings.
Ship Fragile Documents Poly mailer envelopes keep delicate shipments, such as magazines and brochures, from being torn or stained during transport. The plastic material is resilient, water resistant, and tear resistant but features a smooth texture that won't snag on your documents. Mailers are made with one transparent side along with an opaque backing where you can clearly write out the shipment details.
Multiple Formats and Sizes Stock your supply closet with different types of poly envelopes to suit multiple tasks. Staples offers several sizes, and you'll find both top- and side-opening envelopes for easy access to documents in shelf or cabinet filing arrangements.
Secure Closure Choose string-and-button closure or self-seal poly envelopes for safe mailing and storage. Self-seal products remain closed when bumped and jostled during travel, while traditional string closures can be opened quickly when you use these sturdy plastic envelopes as everyday file folders.
