postal paper

Postal papers and mailing envelopes are typically made from paper (often kraft paper). Many envelopes and mailers also include plastic/polymer components—such as polypropylene or polyethylene liners—and padded mailers add internal cushioning like bubble wrap or bubble-lined layers for protection.

Many envelopes include printed security linings that obscure the contents. Common closure options are gummed flaps, press-and-seal (self-seal) closures, and tamper-evident self-adhesive seals to help keep contents private and secure.

Some stationery and envelopes are explicitly compatible with inkjet and laser printers and are also suitable for fountain pens, markers, and other writing instruments. Product descriptions and reviews often note when envelopes run smoothly through printers.

Yes—some wrapping papers are labeled recyclable, and several padded mailers are made from recycled kraft paper or described as being made from "100% recycled material." Check product labels for specific recycling claims.

Padded mailers protect items with bubble lining or multilayer bubble construction that cushions contents. Some products specify bubble thickness (for example, 2/16 inch) and include polyethylene sheet bubble wrap for added protection.

Common uses include mailing, moving, shipping, and storage; gift wrapping, table covering, and crafting; and stationery uses such as invitations, greeting cards, and handwritten letters.
