A shipping container comprising:
- a box formed of corrugated cardboard and defining an interior;
- and
- a cellulose fiber pad coupled to positioned within an interior of the box, the cellulose fiber pad having cellulose reinforcement fibers interlocked with thermoplastic binder fibers distributed substantially randomly within the cellulose reinforcement fibers, the thermoplastic binder fibers making up about 0.5% to 25% by weight of the cellulose fiber pad, the cellulose fiber pad having a thickness that is at least about 1/16 of an inch, wherein subjecting the repulpable insulation liner to a repulpability test produces greater than 85% fiber yield.
