Usually, snack packages are sealed with traditional heat sealing systems that result in peelable seals – with a common width of 15 to 24mm. The width is necessary to guarantee seal tightness and to create the opening characteristics of a peelable seal. Traditional heat seal systems are cost-effective and very common. However, extensive control samples in the Herrmann Ultrasonics (www.herrmannultrasonics.com) laboratory showed that approximately 40% of heat seals in the market are not peelable or tight. Seals created with Herrmann Ultrasonics sealing systems are tight and peelable, but the previous tool design was too narrow to offer the chips consumer the familiar peelable opening characteristics.
