What is Heat Seal Strength?
Heat seal strength refers to the force required to separate two materials joined by heat sealing. It’s a critical parameter in packaging, especially for flexible films, pouches, and blister packs. Strong seals ensure product safety, extended shelf life, and tamper resistance.
Why is It Important?
Measuring heat seal strength helps manufacturers verify the reliability of packaging under real-world stress. Inadequate seal strength can lead to leaks, contamination, or product failure, especially in food, pharmaceutical, and medical applications.
Applications & Testing
Heat seal strength testing evaluates the durability of sealed joints using standardized conditions of temperature, pressure, and dwell time. This testing is essential for quality assurance and meeting regulatory standards.
Accurate measurement of heat seal strength ensures consistent packaging performance, customer satisfaction, and brand protection.
