This article is part of an engineering knowledge series published by SOPARO®, the manufacturing brand behind Cups24.com. It provides technical insight into paper cup performance based on controlled manufacturing tests and real-world foodservice applications. In frozen dessert applications, paper cup failure is rarely caused by leakage alone. Structural collapse under prolonged low-temperature stress is a more common — and often overlooked —...
