Abstract
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 (55, 75, and 95 μm), sealing temperature (125, 135, and 145 °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 55 to 95 μm reduced adhesion to the cutter but led to higher package distortion. Higher sealing temperatures (145 °C) improved adhesion, yet, when combined with higher filling speeds, seal integrity deteriorated. Optimal conditions were identified at 75 μm thickness, 135 °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
