Our Heat Seal Tester utilizes the precise hot press sealing method to determine critical parameters—including heat sealing temperature, time, and pressure—for a wide range of materials. It is ideally suited for plastic film substrates, soft packaging composite films, coated paper, and other heat-sealable composite films.

The instrument effectively accommodates materials with varying melting points, thermal stability, fluidity, and thickness. Since these physical properties directly influence sealing performance, process parameters can vary significantly. This tester provides the accuracy needed to establish the optimal settings for any given material.

Compliant Standards: ASTM F2029, QB/T 2358, YBB 00122003

Key Features:

User-Friendly Interface: Fully digital display for high precision, simple operation, and intuitive use.
