Abstract
A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.
Claims33
A repulpable shipping container comprising:
- a first paper layer;
- and
- a cellulose fiber pad coupled to the first paper layer, the cellulose fiber pad having cellulose reinforcement fibers interlocked with about 2% to about 25% by weight of a meltable PE/PP bi-component thermoplastic binder fiber distributed substantially randomly, wherein subjecting the cellulose fiber pad to a repulpability test produces greater than 85% fiber yield.
A shipping container comprising:
- a box formed of corrugated cardboard and defining an interior;
- and
- a paper fiber batt placed within the interior of the box and coupled to at least one surface formed of corrugated cardboard, the paper fiber batt including paper fibers bound together by thermoplastic binder fibers, wherein the thermoplastic binder fiber has a length of between about 0.5 mm to about 16 mm, wherein the paper fiber batt is formed of up to 10% by weight of the thermoplastic binder fibers, and wherein the paper fiber batt has a weight of between 1300 and 1600 GSM.
A shipping container comprising:
- a box formed of corrugated cardboard and defining an interior;
- and
- a repulpable insert placed within the interior of the box and formed of a first paper layer;
- and
- a cellulose fiber pad coupled to the first paper layer, the cellulose fiber pad having cellulose reinforcement fibers interlocked with about 5% to about 10% by weight bi-component thermoplastic binder fiber distributed substantially randomly, wherein subjecting the repulpable insulation liner to a repulpabilitv test produces greater than 85% fiber yield.

A shipping container comprising:
- a box formed of corrugated cardboard and defining an interior;
- and
- an insulation liner placed within the interior of the box and formed of a first paper layer;
- a second paper layer coupled to the first paper layer to form an envelope;
- and
- a cellulose fiber batt encapsulated between the first and second paper layers with edges of the first and second paper layers being joined together on all four sides of the cellulose fiber batt, the cellulose fiber batt including cellulose fibers bound together by thermoplastic binder fibers, wherein subjecting the cellulose fiber batt to a repulpability test produces greater than 85% fiber yield.
