The language of envelopes


The gumming maintains the security of the envelope during mailing and ensures the confidentiality of its contents. In addition, each type of gumming adapts to a type of mailing and in some cases are technical imperatives for inserting machines.

Multiple solutions

Remoist gum is traditionally the most common gum and is the most suitable for "mailings" which are going to be inserted automatically, and also very frequent for private correspondence. It is very common for its convenience and ease of use, in administrative correspondence.
Peel and seal and resealable envelopes are two alternative solutions for users. The resealable envelope in particular, makes it possible to re-use the envelope, for internal mail and cost effective postage.

Different requirements

But all these types of gum have conservation requirements when their use is going to be prolonged in time: the storage conditions should maintain temperatures between 15 and 25ºC and air humidity between 40 and 70%.

Adapting Gumming to Different Paper

Certain kinds of paper stipulate the type of gumming to be used: "coloured" and "tyvek," for example, which need suitable adhesives for sticking the side and bottom flaps and for the closing flap (protected self-seal).

Security service

Some glues are used to detect the opening of the envelope by a third person: with the "open plus" system and the "detector" system, you are able to check whether the envelope has already been opened. The "string and button" common in the United States, but not used much in Europe is frequently used in internal follow-up mail which goes through different departments where the contents are modified or changed .
