How Does Film Thickness Affect Packaging Speed?

Film thickness affects packaging speed by influencing heat transfer, flexibility, stiffness, and how smoothly the material travels through automatic packaging equipment. Thin films may heat and seal quickly but can wrinkle or stretch under tension, while thicker films may require longer sealing times and more energy to form reliable closures.

What Causes Sauce Pouches to Burst During Filling?

Sauce pouches may burst during filling when internal pressure exceeds the strength of the film, seals, or spout connection. Excessive filling speed, trapped air, unsuitable sealing parameters, and sudden pressure changes can all contribute to failure.
