For biscuits, potato chips, and other baked and puffed foods, packaging seal integrity is critical to product quality from production to consumption. Seal failures can lead to oxygen ingress, moisture absorption, and microbial contamination – resulting in product spoilage and brand damage. The ASTM D3078 bubble leak method provides a standardized approach for detecting leaks in flexible packaging. The Sumspring MFY-05S Leak Tester is specifically designed to meet this standard, offering precise vacuum control, high‑transparency observation, and reliable results for routine quality control.
