“8.5 x 12” is the outside measurement. The usable inside is smaller because of the side seams and the padding, and many sellers also count the folded flap in the outside length. For example, Uline lists a #2 as 8 1/2" x 12" outside but 8 3/8" x 10 3/4" inside/usable.
Empty weight varies by material and bubble thickness. A common ballpark for a #2 poly bubble mailer is about 0.8 oz each (Uline lists 5 lb per 100 for #2 poly, which works out to ~0.8 oz per mailer).
Yes, only if it stays flexible and no more than 3/4" thick. USPS defines flats as pieces that are over letter size limits but not more than 3/4" thick, and notes that a piece that is rigid or over 3/4" thick is classified as a package.
Sometimes, but not always. Many #2 mailers have usable length under 11 inches (for example, 10 3/4"), so a full 8.5" x 11" sheet may need a slight fold or it may not fit perfectly flat.
Some brands do advertise usable 8.5" x 11" (or similar), so those can fit letter-size paper flat.
Common examples include documents/papers, photos, small items like jewelry/coins/buttons, and soft goods like T-shirts and gloves (when not bulky).
