Abstract
Envelopes for holding one or more items include a first and a second flexible wall. The second wall overlies, and is affixed to the first flexible wall.

Claims27
An envelope for holding an item, comprising:
- a first flexible wall;
- and
- a second flexible wall overlying the first flexible wall and affixed to the first flexible wall about a containment border that encloses a plurality of sides of a containment region defined by the first and second flexible walls, which containment region is configured to contain the item, wherein:
- the second flexible wall comprises at least two overlying layers of paper affixed to each other about an interlayer border that encloses a plurality of sides of an interlayer region defined by the at least two overlying layers of paper;
- the at least two overlying layers of paper are unadhered to each other within at least a portion of the interlayer region;
- and
- the interlayer region is sufficiently empty so that the at least two overlying layers of paper abut each other over a majority of the interlayer region, such that the two overlying layers and the interlayer region are padding-free.
