Some interesting questions when it comes to printing Envelopes
These are some frequently asked questions...
What does "peel and seal strip" mean when we talk about envelopes?
It's a self-closing system. It consists of a silicone strip found on the flap; once the document has been inserted into the envelope, the strip is detached and the flap is automatically glued. This system is very practical and is becoming more and more widespread. Other closing systems require wetting the flap with your tongue or with a wet pad. However, envelopes with a wettable band are also used in automatic enveloping machines, which can be found in the workshops of companies that handle and distribute graphic material.
Do you know the difference between regular envelopes and open-end envelopes?
It's simple: while regular envelopes open on the long side, open-end envelopes open on the short side. In this section you can find the type of envelope that best suits your needs.
When we talk about open-end or catalogue envelopes, what does "postal inspection" mean?
As you may have noticed, for both open end and catalogue envelopes we offer the "windowless, with peel and seal strip and with pull-out for postal inspection" mode. On envelopes prepared for postal inspection, the manufacturer includes the text "for postal inspection, open here" on one of the flaps. In Spain direct mail postage envelopes must include this text, which authorizes the Postal Services to verify that the content is printed advertising.
A brief History of envelopes
Envelopes are a 17th century product, and several envelopes dating from 1615 have been preserved in the Swiss city of Geneva. However, it was not until the nineteenth century when its use became widespread. In 1820, envelopes were put on sale for the first time in the British city of Brighton. The first machine for making envelopes was built in London in 1844; around that time postage stamps also appeared, which generalized the use of standard produced envelopes.
