The Difference Between Large Document Envelopes and All Board Envelopes

July 17, 2025By Hazel Rylands

What Are Large Document Envelopes?

Large document envelopes are large paper envelopes designed for mailing of documents, photos, and printed materials. While they offer some document protection and keep contents neat, they’re flexible and can bend under pressure, making them better suited for less delicate items or shorter mailing distances.

What Are All Board Envelopes?

All board envelopes are rigid envelopes made from sturdy materials like kraft board, offering excellent document protection during mailing. Unlike large document envelopes, they prevent bending or creasing, keeping items like photos, certificates, and important documents pristine. They’re a popular choice for businesses seeking professional, secure packaging solutions.

When to Use Large Document Envelopes vs All Board Envelopes

Choosing between large document envelopes and all board envelopes depends on what you’re sending and how you want it to arrive.

Use large document envelopes when mailing lightweight papers, invoices, or everyday business documents that don’t require extra protection. They’re budget-friendly and ideal for routine mailing.
Opt for all board envelopes for items needing superior document protection - like photographs, certificates, marketing materials, or artwork. They help maintain a crisp, professional appearance during transit, reducing the risk of bending or damage.

For dependable options, All Colour offers a variety of products suited to both needs. Flat envelopes like the C3 White Peel & Seal Pocket Envelopes and C3 White Gusset 140gsm Envelopes are perfect for everyday document mailing.

Meanwhile, alternative choices include the 178mm x 241mm White 350gsm Board Peel & Seal Envelopes and 178mm x 241mm Board Back Envelopes, providing enhanced protection for more delicate or valuable contents.

Which Option Is Right for Your Shipping Needs?

Choosing the best envelope depends on your mailing priorities and the contents you’re sending. If cost-efficiency and simplicity are your main concerns, large envelopes are a solid choice for sending standard documents without added bulk. However, if maintaining a flawless presentation is crucial, such as for important contracts, artwork, or promotional materials, all board envelopes offer superior protection and a polished finish.

It’s important to consider package size, weight, delivery speed, and handling conditions, as all board envelopes tend to be sturdier but may come at a somewhat higher cost. Both envelope types come in various sizes and materials, so it’s worth exploring options that best fit your business needs. Using the right envelope type helps ensure your documents arrive securely and professionally, enhancing your brand’s reputation with every shipment.

Ultimately, selecting the right envelope enhances your document protection and reflects your professionalism.
