The purpose of this test was to prove the effectiveness of the TapTone 4000-DSC Sensor in testing aluminum foil drink pouches for leaks. Leaking pouches can destroy outer packaging and ruin your brand image. More importantly, leaking pouches offer contamination a point of entry into your product, which can cause product spoilage and potential health concerns for your consumers. The TapTone 4000-DSC sensor can test stand-up or gusseted pouches either hot or cold ﬁ lled. The T4000-DSC Sensor is ideal for ﬁ nding potential leakers in aluminum foil drink pouches before they leave your processing plant.
