Enjoy seamless postal delivery with office envelopes and mailing bags designed to keep your mail safe. Business envelopes come in a wide range of layouts and sizes for your specific mailing requirements. Send confidential documents with sealed types such as gummed envelopes. Self-seal business envelopes save you time during bulk postage. With biodegradable adhesives, most business envelopes have a long shelf life. Catalog envelopes come with ample room to send print publications you do not want to fold. If you are shipping something fragile, padded envelopes and bubble mailers will protect your package from bumps and breakage. Consider buying windowed office envelopes for an easy display of recipient name and address.

Put it on Display

Most envelopes come with printable surfaces so you can customize your mail for brand awareness. Windowed office envelopes like the Quality Park 21316 make it easier to address the letter. Full windowed envelopes help showcase your aesthetically designed content or business items, making your mailer stand out from the competition's mail.

Enjoy Stress-Free Mailing

Whether you are sending client correspondence or an internal business communication, simple office envelopes provide seamless posting. Their lightweight designs save you valuable shipping and mailing costs. Integrated with built-in sealing mechanisms, these envelopes simplify packaging and save you time. Security envelopes printed with identifying patterns help you safely send confidential documents.

Ship Unfolded Publications Without Damage

Catalog and booklet envelopes have enough room to accommodate bulky letter-sized documents without folding. Open-end catalog envelopes have a flap on the short side, while booklet envelopes are opened from the longer side. Find Kraft paper and paper stock envelopes with a metal clasp for solid content protection against tears and opening.

Safeguard Fragile Content

With internal padding, bubble mailers cushion your fragile objects from mechanical damage while in transit. Mailer envelopes like the Sealed Air 10477 come equipped with tamper-evident seals for added security. Poly mailer envelope bags with white exteriors and black inner linings make the bags opaque, increasing product privacy. Heavy-duty envelopes made from durable tear-proof materials protect contents from water damage. Flexible poly mailers made with thin and lightweight materials accommodate varying shapes of contents for increased versatility.

Envelope Moisteners and Openers Simplify Mailing

Avoid the hassle of licking glue by using convenient envelope moisteners. Most moisteners come in a transparent bottle, offering easy monitoring of content levels. Sturdy construction prevents cracks and breaks that may cause unwanted leakage. Many moisteners have sponge tips that simplify application on the envelope flaps to save you valuable time for bulk mailing projects. These shipping and mailroom supplies are often refillable to save you replacement costs. Letter openers come with a stainless steel blade for quick package opening. Most have recessed safety razors that slit the top edge of the flap safely, minimizing the risk of accidental cuts.

Send More Than Just Letters

Consider mailing more than just office envelopes for letters. Get a square windowed envelope for CDs and DVDs, or the windowless Quality Park E7261. A vinyl LP mailer pad made from sturdy tuff 32ect corrugation protects your records in transit.
