shipping mailer

Common closure types shown include: self-adhesive (self-seal) closures, clasp closures, gummed (moisten-to-seal) flaps, and some boxes or rolls listed with no closure.

Typical materials shown are kraft paper (paper mailers and envelopes), polyethylene (bubble lining and some mailers), cardboard (mailing boxes), and general paper stock for standard envelopes.

Self-seal padded mailers use a pressure-sensitive adhesive strip that bonds the flap and provides a tamper-evident closure; gummed-flap envelopes require moistening the adhesive on the flap and pressing it closed to form a secure seal.

Cushion wrap is shown as a 12 in. x 60 ft. roll with perforations every 12 inches for easy tearing; it’s described as a lightweight, clean padding option for delicate items.

Padded mailers provide protection with bubble-lined walls, multilayer padding (noted examples include 2/16" bubble and air-cell technology), tamper-evident self-adhesive seals, and heat-bonded, watertight seams; cushion wrap adds perforated, lightweight, non-scratching padding and is described as recyclable in some areas.

Package quantities vary from single-count items to multipacks. Examples shown include 1-count boxes, 3-count envelopes, packs of 10, 25, 50, a 96-count envelope pack, and options up to 100.

They’re intended for documents and papers (letters, invoices), photos and 5x7 prints, invitations and greeting or bridal cards, and small items such as jewelry, coins, and other small valuables.

Some mailing boxes are labeled recyclable, and at least one padded mailer is described as made with 100% recycled material. Cushion wrap notes that it may not be recyclable in all areas and is made from the same material as plastic bags.

Mailing boxes are described as easy to assemble and ready for shipping or storage, with printed areas for sender/receiver addressing and design features that provide stacking strength for transport and storage.
