The first structural change in the manufacture of paper cups within the century: Traditional rolled-edge rims are prone to deformations under pressure and heat, having a have chance of bursting, drink-spilling, and causing scalding issues. Totempak’s Frame-Rim design owns worldwide patents, and is boasted to be the safest paper cup in the world.

PP Frame-Ring Structure
The rims of the PP Frame-Ring structure offer a high degree of stability. The smooth-surface plastic frame-ring design reduces the degree of difference between the cup and the lid, also offers a reliable design due to the PP ring-structure, thus, would not undergo deformations when under high-heat or humidity, efficiently reducing the risks and dangers of spilling and bursting.
