Heat Seal Strength Tester for Flexible Pouches

Tensile unit with seal-specific grips that pulls a sealed strip apart to measure the force needed to open the seal. Used by pouch converters to control sealing temperature, dwell and pressure.

Specification

A 15 mm or 25 mm strip cut across the seal is placed in the grips and pulled apart at 250 mm/min. Peak force and failure mode show whether the pouch will survive handling or open cleanly. The data supports the setting of heat seal bar parameters on pouch-making machines.

Features

• Load cell with 100 N capacity
• Grip alignment for T-type seal pull
• Software showing peak force and failure mode
• Strip cutter included
• Overload protection
