A padded mailer by Bubble Wrap

Padded mailers are padded envelopes used for packaging products for shipment. They are sometimes known as Jiffy bags.

Uses

Mailing envelopes and small packages my receive as many as 27 handlings during shipment with the maximum drop height of 1.2 m.^[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

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

Exterior

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

Padding

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

Closure

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 Considerations

A Life Cycle Analysis as been 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.^[5]
