The DIN Long envelope (often abbreviated as DL) is the undisputed standard for everyday business correspondence and high-quality private mail. With classic DIN Long dimensions of 220 x 110 mm, this format provides the perfect setting for double-folded DIN A4 documents or special DIN Long cards (210 x 105 mm). Whether in serious white for office supplies or in bright colors for eye-catching marketing campaigns, at Kuvertwelt.de you will find a huge selection of DIN Long envelopes in a wide variety of designs, available directly from stock. Our envelopes impress with their first-class workmanship and are available with or without windows to suit every mailing purpose.
The DIN Long format: Perfect dimensions for business and marketing
In the world of envelopes, the DIN Long format is indispensable. It was specially developed to perfectly accommodate a DIN A4 sheet that has been folded twice horizontally (wrap fold or Z-fold). But it's not just government agencies and companies that use these 220x110 mm envelopes; they are also the first choice for sending flyers, monthly calendars, or elegant invitation cards for weddings and anniversaries.
Comparison of closure types: wet bonding vs. adhesive bonding
Depending on the intended use and desired appearance, we offer our DL envelopes with different types of closures:
- Wet adhesive (with pointed flap): The classic choice for invitations. The pointed flap on the back is activated by moistening. For larger quantities, we recommend our "Lecki" moistening pen from our range of accessories.
- Adhesive (with strip-off strip): Particularly practical for fast-paced office work. The adhesive strip is protected by a protective paper that can be easily removed. These DIN Long envelopes usually have a straight, modern flap and a long shelf life of up to 5 years.
Colorful variety: DIN long envelopes in every color
A colored envelope ensures that your message does not get lost in the daily mail. At Kuvertwelt.de, you can order colorful envelopes in an impressive range of colors, down to the last piece:
- Classic colors: cream, blue, green, red, and burgundy for stylish letters.
- Exclusive highlights: Gold and silver envelopes and marbled paper for festive occasions such as Christmas.
- Trendy materials: DIN long envelopes made of kraft paper (125 g/m²) for a popular vintage look or transparent sleeves for a milky translucent effect.
Important information about grammage and paper quality
The feel of an envelope often determines how valuable its contents are perceived to be. Please note that our range includes **different grammages**. Contrary to the assumption that all papers have a standard thickness, we offer the right solution for every need:
- 75g/sqm to 80g/sqm: The lightweight standard for postage-optimized bulk mailings.
- 90g/sqm to 100g/sqm: Premium quality for business mail and official correspondence (often with pressure-sensitive adhesive or metallic colors).
- 120 gsm and above: Particularly strong paper, such as our kraft paper, for an extremely stable and high-quality feel.
