BIODEGRADABLE MULTI-LAYER PASSIVE THERMAL INSULATOR MATERIAL

摘要

Disclosed herein is a general purpose, low-cost, highly efficient, biodegradable multi¬ layer, passive thermal insulator material that can be used for packaging in any application where tight temperature tolerance is required for extended periods. The material comprises inner layers between two outer layers. The outer layers can be themselves multiple layers that may provide strength and moisture protection to the structure. The inner layers can comprise a series of alternating courses of continuous material and discontinuous material containing gaps that can form pockets where the continuous layers are arranged to provide a barrier to seal a gas in the pockets in the discontinuous material.
