Property
Specifications
Fusing compatibility
All inks, adhesives, and other materials that are used in the
envelope construction must be compatible with the heat and
pressure of the fusing process. Materials must not scorch, melt,
ignite, offset materials, or release undesirable emissions when
heated to 205°C (401°F) for 0.1 second (0.2 second for HP color
LaserJet printers).
Dimensional accuracy and construction quality
Envelopes must be folded within ±1 mm (±0.04 inch) of nominal
size and have no more than two thickness of paper anywhere along
the leading edge.
All folds must be sharply creased and construction must be tight
(not baggy) to avoid wrinkling.
Envelopes must not be stuck together from excess seam adhesive.
The envelope flap must lie flat (within 1.5 mm [0.059 inch] over the
width where the adhesive is applied).
Curl
Envelopes must lie flat, with no more than 6 mm (0.25 inch) curl
across the entire surface.
Moisture content
4% to 6% by weight.
High moisture content can cause some envelopes to seal shut due
to elevated temperatures when steam is released during fusing.
Grain
Different types of envelope construction might require different
grain orientations for best performance, which is left to the
discretion of the converter. For more information, see the support
documentation that came with your printer.
Packaging
Protective box to prevent edge damage and maintain flatness.
