This especially sturdy and high quality mailer, which is made from white duplex board, is perfect for mailing brochures, business files or photographs but also for delivering goods, magazines, thin books, catalogues, etc. The long flap is self-sealing and can be easily and cleanly opened by means of tearing along the perforated line provided. In addition, the envelopes have perforated holes on the opening side which allows them to also be sealed by means of BRASS FASTENERS.
Please note that postage can be higher depending, of course, on the weight and format of the contents. The minimum and maximum dimensions and weights can be found under www.deutschepost.de. The official policy of the German post office is to demand higher postage for mail that cannot be machine read like dark or patterned envelopes and plastic covers. In fact, this really only applies to commercial mailings – occasional private customers are usually not charged. Stamped coloured standard envelopes in smaller quantities (up to 5) are accepted by the post office. Business customer mailings in larger quantities must be capable of being sorted in an automated system. For an easy and gratis Certification (of suitability) for your envelopes, please contact the post office.
Envelopes are usually available with three different types of seals. In order to avoid any confusion, here is a short explanation of the most used terms:
- A gummed envelope has a strip of gum on the flap that is activated by moisture (licking).
- A press seal envelope is closed by folding down a flap and pressing the two strips of glue together. No moisture is required.
- Peel and seal envelopes are closed by removing the strip that covers the adhesive on the flap and pressing the flap into place.
What is the difference between envelopes on the one hand and mailers on the other? An envelope on which the flap is on the short side is called a mailer; if the straight or pointed flap is on the long side it is called an envelope.
The most common sizes of mailers are as follows:
DIN C5 162 x 229 mm
DIN B5 176 x 250 mm
DIN C4 229 x 324 mm
DIN B4 250 x 353 mm
DIN E4 280 x 400 mm
Size and position of the DIN window:
DIN C5, B5:
The size of the window is 45 x 90 mm and its position when the mailer is horizontal is on the left (flap on the right) with a 60 mm margin from the bottom and 20 mm margin from the left side.
The size of the window in 55 x 90 mm and its position when the mailer is upright (flap at the top) is on the left side with a 212 mm margin from the bottom and a 20 mm margin from the left.
Because the post office is constantly changing the maximum size and limitation parameters, we refer you here to the hopefully always current Deutsche Post webpage: www.deutschepost.de. There you can also consult the German post office postage calculator (only in German although some info in English can be found on the Internet).
