Claims14
A modular box assembly comprising:
- a box formed of a paper blank, the box comprising multiple side box panels and a bottom box panel and defining an interior and a bottom;
- an insulation liner positioned within the box interior, the insulation liner constructed of a length of a batt assembly, the batt assembly comprising an insulation batt in facing contact with a first paper layer and with a second paper layer, the insulation liner defining multiple sections,
- wherein at least one section of the insulation liner contacts a side box panel of the multiple side box panels, and wherein another section of the multiple sections of the insulation liner contacts the bottom box panel;
- and
- wherein the insulation batt is formed from a mixture of 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 insulation batt, the insulation batt having a thickness that is at least about 1/16 of an inch,
- wherein the thermoplastic binder fibers are comprised of a bi-component fiber comprised of polyethylene (PE) and polypropylene (PP),
- wherein a ratio of PE to PP ranges from 50/50 to about 65/35.
