Padded envelope
Apadded envelope,also known as apaddedorcushioned mailer,orjiffybagin the United Kingdom, is anenvelopeincorporating 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.Cushioningor 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 heavypaper,paperboard,corrugated fiberboardorplastic film.
Padding[edit]
The padding material can be recyclednewsprint,foam,bubble wrap,or othercushioningmaterials.
Closure[edit]
Many mailers have an integral flap that has apressure-sensitive adhesive,a gummed (water-activated) adhesive, ortapeto allow easy and secure closure.
Environmental impact[edit]
ALife Cycle Analysiswas conducted to compare a Kraft paper mailer with newsprint padding to aLDPEplastic 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]
