The 9oz cup features a relatively compact design with moderate height and overall structural stability. This specification imposes manageable requirements on paper weight during practical use. As long as the cup proportions are reasonable and forming quality is consistent, it can meet hot beverage requirements, with the key focus being reliable forming at the rim and base.

12oz is a commonly used standard specification in the Belarusian market. This specification typically ensures stable performance during use by moderately enhancing paper strength and controlling forming parameters.

The 16oz size represents a larger capacity specification, featuring increased cup height and weight capacity. This demands higher standards for cup wall strength, base sealing integrity, and overall molding stability. For this size, selection places greater emphasis on matching paper stiffness with cup structure to ensure upright stability and safe handling under hot beverage conditions.
