Business and Commercial Envelopes

Your business should be as professional as possible. Business and commercial envelopes are the right choice for both your clients and employees. For more serious circumstances, choose a crisp white or off-white envelope. If you really want to stand out, choose an envelope in a popping hue, like red or yellow, or an envelope that matches your clients’ company colors.

Social and Invitation Envelopes

Social and invitation envelopes are great to use for events, greeting cards, thank you notes, photo cards, special announcements, weddings and more. If you want your message noticed, pick an interesting size, material style, and color! [table id=5 /]

Promotional

Promotional envelopes are your go-to for any other need that isn’t social or business related. For example, if you need to send something that needs some protection, choose our bubble mailers. Or maybe you need to send artwork or important papers. Choose our sturdy photo mailers! OR maybe your company wants to send out larger magazines or promotional brochures. Our large open end envelopes are the way to go. Basically, anything that won’t fit into our other envelope categories, you can find it in the promotional group of envelopes. [table id=8 /]

Guide to Envelope Sizes

Envelopes are essential for mailing letters, invitations, and other documents, but choosing the right size can be confusing. This article aims to simplify the process by providing a detailed overview of envelope sizes and styles. Whether you are sending a standard letter or a bulky document, understanding the different envelope sizes and styles available will help you ensure that your mailings are professional and well-presented.

Key Summary:

  • This article serves as a comprehensive guide to envelope sizes, providing readers with detailed information on different sizes and styles to help them find the perfect envelope for their needs.

Common Envelope Sizes:

When it comes to common envelope sizes, #10 envelopes are the most widely used for business correspondence and standard letters. They typically measure 4 1/8 x 9 1/2 inches and can hold a standard 8.5 x 11-inch piece of paper folded into thirds. A2 envelopes, on the other hand, are commonly used for invitations, thank you cards, and RSVPs. They are smaller in size, measuring 4 3/8 x 5 3/4 inches, and are perfect for smaller cards and notes.

Specialty Envelopes:

Specialty envelopes offer unique features that cater to specific mailing needs. Window envelopes have a transparent window that allows the address to show through, eliminating the need for labeling. Coin envelopes are small, sturdy envelopes often used for storing coins, small parts, or seeds.

Envelope Styles:

Envelope styles play a significant role in the overall look and functionality of the envelope. Gummed flap envelopes have a traditional adhesive strip that needs to be moistened before sealing. Self-seal envelopes have a peel-off strip that allows for easy and quick sealing without the need for moisture. Peel & Seal envelopes feature a self-adhesive strip that is activated by removing a protective cover, making them convenient and secure for mailing.

Envelope Materials:

Envelope materials can vary based on the intended use and durability requirements. Paper envelopes are the most common and come in a range of weights and finishes to suit different needs. Kraft envelopes are made from recycled paper and have a natural, earthy look that is perfect for eco-friendly mailings. Plastic envelopes are durable and water-resistant, making them ideal for protecting important documents during transit.
