    摘要: Syrup dispensing cups are provided that include a body structure that includes a first polyester or co-polyester resin with one or more first co-monomers incorporated into the first resin at a first mol % and having an intrinsic viscosity from about 0.45 dL/g to about 1.3 dL/g when measured at a temperature of 25 C. The body structure has a first opening that is sealed with a first sealing layer and a second opening sealed with a second sealing layer, in which each sealing layer includes a second PET-based co-polyester resin having one or more second co-monomers incorporated into the second resin at a second mol %, and the ratio of the first mole % to the second mol % is less than 1. Methods for or enhancing the shelf-life of syrup dispensing cups are also provided.
