Abstract
A method and system for producing an insulated mailer and an insulated box having an insulative paper fiber pad substructure with a density of less than about 10 pounds per cubic foot. The insulative paper fiber pad has entangled reinforcement fibers. A method of forming an insulative paper fiber pad using recycling-compatible or water soluble adhesive and paper layers is provided.
Claims1
A repulpable insulation material comprising:
- a batt formed of a mixture of cellulose fiber and between about 0.5% and about 25% thermoplastic binder fiber distributed substantially randomly within the cellulose fiber, said thermoplastic binder fiber being adhered to the cellulose fiber, wherein the thermoplastic binder fiber has a length of between about 0.5 mm to about 16 mm, and wherein subjecting the repulpable insulation material to a repulpability test produces greater than 85% fiber yield.
