Two Wide Mailers
Mailers can be manufactured two wide. They are generally
used only for large runs of high usage mailers. Two wide mailers will
cut imprinting time in half if there are no major problems that occur
in running them through the printer. The extra glue lines close to
the data imprint areas and across the width of the printer can be
too thick for the printer to handle. Be sure to run test samples before
Another type of two wide mailer is the pseudo mailer.
The pseudo mailer has a mailer on one side and a form on the other
side. It can be used when the sender needs several copies of the mailer's
content. The mailer gets printed on one side and the copies are printed
on the other side. The pseudo mailer is used to reduce the thickness
of the mailer. If the sender needed 3 copies and the mailer consisted
of one insert, a one wide mailer would have 6 parts. Running this
mailer two wide would reduce it to a 3 part mailer on one side, with
a 3 part form on the other side to be used to retain as copies.
Unit Set Mailers
Mailers can be manufactured as a unit set instead
of continuous. A unit set mailer is constructed basically in the same
manner as a continuous mailer. The difference would be that the lineholes
would be trimmed at the collator and it would be cut off as an individual
form instead of being fan folded. The mailer would have to be imprinted
on a typewriter or filled out by hand.
Sometimes a special insert needs to be added to
the mailer after the mailer has been imprinted by the sender. There
are several ways that this can be accomplished.
When using one of the insert
slit features, be sure that the special insert does not increase
the weight of the mailer so that it is heavier than what the
prepaid postage will cover.
Perforation on Back of Mailer
A perforation parallel to the stub perfs can be
added to the back of the mailer. A file hole punch is punched on the
perforation to allow an object, such as a letter opener, to be inserted
to assist in breaking the perforation. The special insert is added
and the opening can then be sealed with tape.
Slit on Back of Mailer
A partial slit can be added to the back of the mailer
so that a special insert can be added without having to break open
a perforation. The slit is then also taped to seal it. If an insert
needs to be added frequently, the slit may be preferred over the peforation.
An open edge with pressure sensitive tape for sealing
is another option for adding special inserts. The mailer is glued
on the top, bottom and one edge. The other edge is left unglued and
PS tape is applied at this edge. When the stubs are removed for mailing
the unglued edge is open, allowing a special insert to be added by
hand. Then the PS tape liner is removed to expose the adhesive strip
and the mailer can then be sealed.
