Abstract:

An environmentally friendly sheet material, and thermoformed products made with that material. The two-, three- or four layer environmentally friendly sheet material is especially suited for use in connection with the manufacture of cups and similar containers and products. In a two-layer compostable sheet, the first layer is a relatively thick layer containing up to 50% additive. The second layer is a relatively thin layer of substantially clear compostable material. The two-layer sheet material is preferably made by co-extruding the first and second layers together. The multi-layer material and the products therefrom of the invention exhibits surprisingly high gloss levels on one side thereof.
