Abstract: Thermoformed polymeric foam articles are described herein In some embodiments, the articles are made by a manufacturing method (e.g., a continuous process) which involves the extrusion and subsequent thermoforming of a blowing agent containing thermoplastic sheet. The thermoformed polymeric foam articles may have a lower density than the precursor sheet from which they are formed. In some but not all embodiments, the precursor sheet is a multi-layer sheet which includes at least one foam layer. In such embodiments, the thermoformed articles also include multiple layers and at least one foam layer.

Abstract: Thermoformed polymeric foam articles and methods of forming the same are described. In some embodiments, thermoformed articles are produced from multi-layer foamed sheet where the formed article has a density equal to or less than the precursor multi-layer sheet. One of the layers of the thermoformed article may be a polymer foam layer having a density reduction between 5% and 50% as compared to the solid polymer. Such polymer foam layers can be referred to as “medium density” or “high density” foams. Advantageously, the methods described herein are practical for commercial use and, for example, can be used to produce a variety of thermoformed articles suitable for use in many different applications.
