Abstract
An insulated container may include a rigid container surrounding an insulation layer formed from a post-industrial, pre-consumer card waste. The insulation layer may be characterized by a lack of any wrapping material. The insulation layer may be manufactured using a variety of converting processes including, carding, airlay, and needle punch to form a non-woven material for providing consistent density throughout the insulation layer. The insulation layer may include a natural fiber lamination layer on an outer surface of the insulation layer. The insulation layer may be biodegradable in an anaerobic environment.
Claims4
A method of making an insulated container comprising the steps of:
- providing a rigid container;
- providing a quantity of post-industrial, pre-consumer cotton waste;
- processing the post-industrial cotton waste into a sheet;
- converting the waste via one or more converting processes including:
- carding, airlay, and needle punch to achieve a specified thickness and density;
- laminating a natural fiber lamination layer, comprising only a single layer, to the sheet cutting the sheet into rectangular sections;
- forming the rectangular sections into interlocking C-shaped members;
- and
- placing the interlocking C-shaped into the rigid container.
