Padded envelope

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.

[2][3][4][5] The exterior envelope can be made of a heavy paper, paperboard, corrugated fiberboard or plastic film.

The study recommended use of future products with lower mass and which use renewable resources.
