7oz This cup specification features a compact design with a lower profile and overall structural stability. Due to its concentrated load-bearing structure, it meets hot beverage requirements even with standard paper configurations. The primary focus is on the stability of the rim curl and base seal

The 9oz cup size falls between the small and regular cup sizes in terms of height and capacity. Its increased height places higher demands on wall stiffness. For this specification, achieving optimal cup proportions and stable molding parameters are critical to ensuring reliable performance.

The increased overall weight capacity of the 12oz cup body after liquid filling demands higher standards for paper strength and forming quality. When selecting this specification, greater emphasis is placed on the coordination between paper stiffness and forming consistency to ensure the cup maintains its upright shape and remains safe for use under hot beverage conditions.
