The DL envelope—also known as the “No. 10” or “business” envelope—is one of the most popular sizes in printing and packaging. Measuring 110×220 mm, it’s specifically designed to hold an A4 sheet folded into thirds. At Nami Naghsh Printing Complex, we produce DL envelopes with premium quality and custom designs to serve businesses, offices, and individuals. Beyond being a practical mailing tool, it’s also a great branding medium: by printing your logo, contact details, and creative graphics, you present a professional image of your business.
The DL format dates back to the 1920s in Germany, where it was known as DIN Lang (long side). Based on ISO 216 standards and part of the A-series ecosystem, DL envelopes were created to streamline business correspondence and quickly spread across Europe and beyond. In the United States, this size is commonly called the DL or “business” envelope and has been a standard for professional mail since the 1950s. With advancements in printing, DL envelopes evolved from basic papers to more durable, recyclable options. Today, with a focus on sustainability, many are made from recycled stocks.

DL envelopes can be made from various materials to suit different needs. Kraft paper is a popular, tear-resistant option made from natural wood pulp—typically 80–120 gsm—for everyday use. Recycled paper is eco-friendly and can be up to 100% recyclable. For luxury applications, coated papers with matte or gloss finishes enhance print clarity and color. At Nami Naghsh Printing Complex, we use high-quality, FSC-certified papers from responsibly managed forests to ensure durability and sustainability. Water-resistant options are also available for international mailing.
Printing techniques play a major role in final quality. Offset printing is ideal for large runs, transferring ink from plate to blanket to paper for precise, consistent results. For smaller quantities, digital printing is perfect for quick, customized jobs. Advanced techniques like UV printing create glossy, fade-resistant finishes, while flexography works well on textured or uneven stocks. At Nami Naghsh Printing Complex, we use modern machinery to achieve vibrant colors and sharp details.
DL envelopes have wide-ranging uses. Businesses rely on them for invoices, contracts, and official letters; government offices and companies use them for both internal and external communications. In marketing, custom-printed DL envelopes can carry brochures and introduce your brand to new audiences. Benefits include low cost, easy handling, and recyclability. Their light weight helps reduce postage, and custom printing boosts trust and loyalty. Research shows branded envelopes can raise response rates by up to 30%.
