What is Stora Enso Paper Cupstock?

Premium paper cup raw materials

When talking about paper cup materials, one name that frequently comes up in the global packaging industry is Stora Enso. But what exactly is Stora Enso paper cupstock, and why is it widely used in paper cup manufacturing? Let’s break it down.


What Is Paper Cupstock?

Cupstock (also called cup board or paper cupstock) refers to a specialized type of paperboard that’s engineered specifically for the production of paper cups and similar foodservice containers. This material must meet stringent requirements: it must be food-safe, moisture-resistant, heat-resistant (especially for hot drinks), and perform well in high-speed converting and printing machines. 

Stora Enso’s paper cupstock is one of the most established and widely adopted options in the global market due to its performance, sustainability credentials, and consistency.


Who Is Stora Enso?

Stora Enso is a leading Finnish-Swedish forest-based materials company with centuries-old roots in the paper and packaging industry. The company focuses on renewable materials to replace fossil-based plastics in everyday packaging applications, from foodservice materials to industrial packaging.


What Makes Stora Enso Cupstock Special?

Stora Enso’s paper cupstock (often under product names like Cupforma Natura™) stands out for several key reasons: 

✔️ High Performance
