How Soft Pack Facial Tissues are Heat-Sealed at the Factory
Precision thermal management in high-speed flow wrapping operations is the definitive baseline for preventing seal failure and maintaining product sterility in the 2026 flexible film tissue sector. This technical analysis examines the structural transition from rigid cartons to multilayer thin-gauge laminates, detailing how a uniform $\pm 0.5^\circ\text{C}$ thermal profile across sealing jaws eliminates micro-leaks during continuous 300+ PPM production cycles.
