plastic mailer

Most items in this selection are made from polyethylene or other plastics. Some mailers use a kraft paper outer shell combined with a bubble lining for cushioning.

Most padded mailers use a self‑adhesive, self‑seal flap that creates a tamper‑evident closure. Some items (for example, cushion wrap rolls) have no built‑in closure.

A few listings specify bubble or lining thickness. Examples include a 2/16‑inch bubble lining on certain kraft mailers and 3/16‑inch (high‑quality) bubbles on some poly mailers.

Pack counts vary widely across listings, from single units up to bulk packs such as 10, 50, 250 and 500.

Product descriptions indicate the mailer surfaces are suitable for handwriting and that ink, stamps and mailing labels adhere easily to these padded mailers.

Many listings describe self‑adhesive, self‑seal flaps marketed as tamper‑proof or tamper‑evident; several state that once sealed the envelope cannot be resealed without visible damage.
