A padded envelope by Bubble Wrap

A padded envelope, also known as a padded or cushioned mailer or (UK) jiffy bag, is an envelope incorporating protective padding to protect items during shipping. The padding is usually thick paper, bubble wrap, or foam.

Uses[edit]

Mailing envelopes and small packages may receive as many as 27 handlings during shipment with the maximum drop height of 1.2 metres (3.9 ft).[1] The contents of the mailing envelopes often need protection from shock and vibration damage. Cushioning or padding can be built into the mailing envelope to help protect the contents.

Construction[edit]

Several constructions are available.[2][3][4][5]

Exterior[edit]

The exterior envelope can be made of a heavy paper, paperboard, corrugated fiberboard or plastic film.

Padding[edit]

The padding material can be recycled newsprint, foam, bubble wrap, or other cushioning materials.

Closure[edit]

Many mailers have an integral flap that has a pressure-sensitive adhesive, a gummed (water-activated) adhesive, or tape to allow easy and secure closure.

Environmental impact[edit]

A Life Cycle Analysis was conducted to compare a Kraft paper mailer with newsprint padding to a LDPE plastic mailer with air bubble padding. Both had advantages and disadvantages; overall, the Kraft padded mailer had a higher overall environmental impact compared to the LDPE bubble mailer. The study recommended use of future products with lower mass and which use renewable resources.[6]
