Permanent Line Gluing - Permanent line gluing
is applied as hot glue or cold glue. Both can be used in gluing parallel
to the stubs but cross web gluing is generally applied only with cold
glue. Hot glue is harder to work with but does set up faster. Permanent
line gluing is generally used in stub areas that will be detached
or between parts that do not have to be separated. This type of gluing
provides the most security to the content of the mailer.
Permanent Spot Gluing - Permanent spot gluing
is generally used on a mailer that has some type of peel apart feature
to it. The spot gluing allows the parts to be peeled apart easier
but will leave some fiber residue in the spot glue areas.

Fugitive Gluing - Fugitive glue is a type
of glue that will hold the parts together but allows them to be separated
more easily with less fiber residue in the glue area than permanent
line gluing. Fugitive glue is used between parts where one of the
parts has to be reused, for example where one of the parts is part
of the reply envelope. Using fugitive glue des not provide as much
security to the mailer content as using permanent glue.
Fugitive Spot Gluing - Spot gluing with fugitive
glue provides the least amount of adhesion between mailer parts. It
is used when ease of separation is a concern. It would be a good choice
when a minimal amount of residue is desired between peeled apart sections.
But, it provides the least amount of sealing security to your mailer.
