Multi-layered suspension package assembly
A packaging device can include a retention member formed of two layers that are different from one another. In some embodiments, the two layers are made of different material, connected together such as by heat sealing. The layers can be made from different materials or the same materials having different thicknesses, modules of elasticity, melting index, or other different characteristics. In some embodiments, the two layers have different physical dimensions.
1. A suspension packaging assembly comprising:
at least one frame member having a central portion with a first end and a second end disposed opposite the first end relative to the central portion, a first foldable portion disposed at the first end and a second foldable portion disposed at the second end;
a resilient retention member assembly comprising a first layer having first and second longitudinal ends and first and second lateral edges, and a second layer having first and second longitudinal ends and first and second lateral edges, the first layer heat sealed to the second layer along respective first and second lateral edges to form an enclosed, interior space, the first and second longitudinal ends of the second layer being engaged with the first and second foldable portions, respectively;
wherein an opening to the interior space between the first and second layers is defined between an upper surface of the second layer and the first longitudinal end of the first layer.
2. The suspension packaging assembly according to claim 1 , wherein the first layer is made from a material that has a first longitudinal length defined by a distance between the first and second longitudinal ends of the first layer and the second layer is made from a material having a second longitudinal length defined by a distance between the first and second longitudinal ends of the second layer, the first longitudinal length being smaller than the second longitudinal length.
3. The suspension packaging assembly according to claim 2 , wherein the first longitudinal ends of the first and second layers are aligned with each other and the second longitudinal ends of the first and second layers are offset from each other.
4. The suspension packaging assembly according to claim 1 , wherein the first layer is formed of a material having a first modulus of elasticity, the second layer being formed of a material that has a second modulus of elasticity that is different from the first modulus of elasticity.
5. The suspension package assembly according to claim 1 , wherein the first layer is translucent and the second layer is opaque.
6. The suspension package assembly according to claim 1 , wherein the first layer is thinner than the second layer by at least one mil.
7. The suspension package assembly according to claim 6 , wherein the first layer is thinner than the second layer by at least three mils.
8. The suspension package assembly according to claim 1 , wherein the first layer is made from low-density polyethylene (LDPE) and the second layer is polyurethane.
9. The suspension packaging assembly according to claim 1 , wherein the first longitudinal end of the first layer is disposed on an opposite side of a fold connecting the first foldable portion with the central portion of the frame member such that folding the first foldable portion with respect to the central portion constricts the opening to the interior space between the first and second layers.
10. The suspension packaging assembly of claim 1 , wherein the second layer is attached with the first and second foldable portions, respectively, by first and second pockets.
11. A suspension packaging assembly comprising:
at least one frame member having a central portion with a first end and a second end, a first foldable portion connected at a first end and a second foldable portion connected at the second end;
a resilient retention member assembly comprising a first layer having first and second longitudinal ends and first and second lateral edges, and a second layer having first and second longitudinal ends and first and second lateral edges, the first layer attached to the second layer along at least the first and second lateral edges, the first and second foldable portions engaged with the first and second longitudinal ends of the second layer, respectively;
wherein an opening to a void between the first and second layers is defined between an upper face of the second layer and the first longitudinal end of the first layer;
wherein the first longitudinal end of the first layer is disposed on an opposite side of a fold connecting the first foldable portion with the central portion such that folding the first foldable portion with respect to the central portion constricts the opening to the void.
