"A" SERIES
Square flap announcement style envelopes ranging in size from A-2
to A-10.
ACID FREE ENVELOPES
Envelopes made from virtually any cellulose fiber source (cotton,
wood, etc.) and buffered with an alkaline substance to resist acid
deterioration. Bleaching, aluminum sulfate, or pollutants in the
atmosphere may lead to the formation of acid if a paper or board
has not been buffered with an alkaline substance.
ADDRESS BLOCK BARCODE
A barcode contained within the address block, as opposed to one
in the lower right hand corner of a mail piece.
ADHESIVE
Also known as gum, this is the substance used to seal an
envelope:
- Back gum is matched to the paper grade to form
strong permanent bonds at seams that form the body of the
envelope.
- Seal gum is also matched to the paper grade,
and when moistened, quickly and securely seals the envelope.
- Pres-Stik® is the trade name for Western
States' latex seal; a self-sealing adhesive requiring no
moisture, which forms a bond when two coated surfaces come
together.

ANNOUNCEMENT ENVELOPES
Envelopes with either deep pointed flaps and diagonal seams, or
deep square flaps with two side seams. They are used with baronial
cards, informal mailings, and social and commercial announcements.
Both styles have their own unique sizes.
