Polyester composition which is particularly suitable for use in thermoforming thin walled articles.

摘要

This invention relates to a thermoplastic resin composition which is particularly suitable for use in thermoforming thin walled articles. The thermoplastic resin compositions are comprised of (1) from about 94 to about 99 weight percent polyethylene naphthalate and (2) from about 1 to 6 weight percent of at least one polyester elastomer. The subject invention also deals with thermoforming such thermoplastic resin compositions into articles, such as food trays, having a crystallinity within the range of about 10% to about 40%.
