Abstract

Container insulation including a batt comprised of large paper particles, at least 90% of which by weight are greater than 10 mm in diameter. Less than 5% by weight binder fibers are used, which have a length of at least 20 mm. Most preferably, no binder fibers are used. Where the batts are faced with paper, the paper is coated with a biodegradable coating. The resulting product is repulpable and recyclable in accordance with Fiber Box Association (FBA) testing protocols.
