Ensuring Traveler Health Through Single-Serve Instant Beverage Packaging: Optimization of Sachet-Filling Parameters for Product Safety and Quality Preservation

Objectives: This study was conducted to ensure traveler health and food safety by investigating the effects of key sachet-filling machine parameters on the quality and safety of single-serve instant beverage packaging.Methods: Three main variables were examined under controlled experiments: metallized film thickness (۵۵, ۷۵, and ۹۵ μm), sealing temperature (۱۲۵, ۱۳۵, and ۱۴۵ °C), and filling speed (slow, medium, and fast). Evaluations focused on three critical indicators package distortion, adhesion to the cutter, and seal integrity—to establish optimal conditions that ensure product safety and maintain packaging quality for single-serve use.Results: Increasing metallized film thickness from ۵۵ to ۹۵ μm reduced adhesion to the cutter but led to higher package distortion. Higher sealing temperatures (۱۴۵ °C) improved adhesion, yet, when combined with higher filling speeds, seal integrity deteriorated. Optimal conditions were identified at ۷۵ μm thickness, ۱۳۵ °C sealing temperature, and medium filling speed, which minimized distortion and adhesion while ensuring high-quality sealing and safe single-serve packaging.Discussion: These findings emphasize the importance of simultaneous optimization of machine parameters to enhance packaging quality and safety in single-serve instant beverage production. The results provide a reliable basis for designing industrial processes that prioritize product safety, minimize health risks for travelers, and ensure consistent packaging performance
