1/1 Summary "Leak-proof Container for Food or Beverage Packaging and Process for Producing a Leak-Proof Container" This invention describes a disposable container Leak-proof, comprising a bottom portion consisting of expandable thermoplastic resin granules and a cover film, to contain non-carbonated beverages or food products that do not require heating before consumption. The inventive container eliminates the use of polypropylene and polystyrene snap caps currently used for cups and containers. the snap-on cover is replaced with a thermoplastic cover film, a leak-proof seal is formed between the cover film and the upper flange of the bottom portion. Replacing the snap-on cover with the cover film reduces the weight of the disposable cover material by 74 percent. Through proper selection of materials, a leak-proof container that is 100 percent recyclable under the # 6 ps (polystyrene) symbol can be produced.
