Abstract

Claims (51)

1 . A method comprising:

receiving a sheet of a packaging material comprising a first layer of a first structural configuration and a second layer of a second structural configuration which differs from the first structural configuration;

applying a force to the sheet of the packaging material;

expanding each of the first layer and the second layer to form an expanded packaging material, wherein expanding the first layer includes unfolding a plurality of folds provided in the first layer; and

forming a packaging enclosure from the expanded packaging material.

2 . The method according to claim 1 , further comprising selecting a length of the packaging material for the packaging enclosure based on dimensions of an item to be shipped in the packaging enclosure.

3 . The method according to claim 1 , wherein expanding the first layer comprises expanding the first layer in a first direction and expanding the second layer comprises expanding the second layer in a first direction.

4 . The method according to claim 3 , wherein expanding the second layer further comprises expanding the second layer in a second direction orthogonal to the first direction.

5 . The method according to claim 1 , wherein expanding each of the first layer and the second layer includes:

expanding the first layer in a first direction;

expanding the second layer in the first direction in response to expansion of the first layer in the first direction; and

expanding the second layer in a second direction which is normal to the first direction.

6 . The method according to claim 5 , wherein expanding the second layer in one or both of the first direction and the second direction occurs one of simultaneously and sequentially with expanding the first layer in the first direction.

7 . The method according to claim 6 , further comprising increasing a thickness of the second layer through expanding the second layer in the second direction.

8 . The method according to claim 6 , further comprising:

increasing a length of the first layer and the second layer through expanding the first layer and the second layer in the first direction; and

narrowing a width of the first layer and the second layer through expanding the first layer and the second layer in the first direction.

9 . The method according to claim 1 , further comprising providing the first layer and the second layer in a recyclable material.

10 . The method according to claim 1 , wherein expanding the second layer includes opening up a plurality of slits provided in the second layer to form air pockets in the second layer.

11 . The method according to claim 1 , further comprising bonding the first layer and the second layer to one another prior to expanding the first layer and the second layer.

12 . The method according to claim 1 , further comprising:

providing a third layer of the first structural configuration in the packaging material; and

positioning the second layer between the first layer and the third layer.

13 . The method according to claim 12 , further comprising:

expanding the first layer and the third layer in a first direction;

expanding the second layer in the first direction;

expanding the second layer in a second direction normal to the first direction; and

increasing a thickness of the second layer as the second layer is expanded in the second direction.

14 . The method according to claim 13 , further comprising bonding the first layer, the second layer, and the third layer to one another in an expanded condition prior to forming the packaging enclosure.

15 . The method according to claim 1 , further comprising:

folding the expanded packaging material about a fold line;

bonding side edges of the folded expanded packaging material to one another; and

defining an interior cavity between a first wall and a second wall and the bonded side edges of the bonded and expanded packaging material.

16 . The method according to claim 15 , further comprising:

inserting an item to be shipped into the interior cavity; and

bonding a top edge of the packaging enclosure to enclose the item to be shipped in the interior cavity and to prevent access to the interior cavity.

17 . A method of forming packaging material comprising:

providing a first layer of a first structural configuration providing a second layer of a second structural configuration that is different from the first structural configuration;

expanding the first layer from a first length to a second length, wherein expanding the first layer includes unfolding a plurality of folds provided in the first layer;

expanding the second layer from a first length to a second length in conjunction with or in response to expansion of the first layer; and

increasing a thickness of the second layer in response to the second layer expanding from the first length to the second length.

18 . The method according to claim 17 , further comprising:

providing a third layer having a structural configuration which enables the third layer to expand from a first length to a second length in conjunction with or in response to expansion of the first layer; and

interposing the second layer between the first layer and the third layer.

19 . The method according to claim 18 , further comprising:

moving the first layer, the second layer, and the third layer into an expanded condition;

forming a front and a back of a packaging enclosure with the packaging material when the first layer, the second layer, and the third layer are in the expanded condition;

defining an interior cavity between the front and the back;

inserting an item into the interior cavity; and

securing the front and back to one another; and

retaining the item in the interior cavity.
