Common closure types include metal clasp closures, gummed (moisten-to-seal) flaps, press-and-seal (self-seal) strips, and self-adhesive strips. Listings may use slightly different names, but these are the typical options.
Envelopes are typically made from paper or polyethylene. Padded mailers usually have a kraft paper exterior with an interior bubble lining (polyethylene bubble wrap or sheet). Some products are described as made from recycled kraft paper.
Options commonly include printed security (tint) linings to block visibility of contents, opaque brown or kraft exteriors that conceal items, and self-adhesive seals described as tamper-evident. Product listings vary, so check individual descriptions for specific features.
A 10" × 13" clasp manila envelope provides approximately 10" × 13" interior space, large enough to hold standard-sized and larger sheets flat without folding.
Product descriptions commonly list papers and documents, letters, photographs and small artworks, and a variety of small goods such as jewelry, stones, coins, and buttons.
Reviewers commonly report that self-sealing and press-and-seal closures are easy to use and provide effective sealing and privacy. A smaller number note that envelopes without self-seal features can be less convenient.
Listed inside dimensions include 9.5" × 13.5", 8.5" × 11", 6" × 9", and 8.5" × 15"—these are the interior sizes shown alongside the respective outside measurements.
