Abstract
Labeled thin-wall containers molded from pre-expanded expandable thermoplastic particles having a label disposed over at least a portion of the outer surface of the container. The particles are coated with a composition that includes at least 2,500 ppm of a salt of a Cto Ccarboxylic acid based on the weight of the particles. The label has a thickness of from 10 μm to 1,500 μm and the sidewall has a thickness of from 0.5 mm to 5 mm. An aqueous beverage at 80° C. does not leak from the container after being left undisturbed for 24 hours and the container has a rim strength of at least 0.54 kg. The containers are made by placing a label against an inner surface of a female portion of a two-part mold; closing the mold to form a mold cavity; filling the mold cavity with the particles; and fusing the particles.
