The KASON-LST600 Leak and Seal Strength Tester is professionally designed for the quantitative determination of seal strength, heat-seal quality, overall bag burst pressure, and seal leak performance across all edges of flexible packaging and aseptic packaging formed through various heat-sealing and bonding processes. It facilitates the analysis of material properties—such as compressive strength and burst strength—utilized in flexible packaging bags. Furthermore, it enables the quantitative assessment of the sealing performance of various tamper-evident plastic bottle caps, the detachment strength of cap connections, and the stress strength of the cap material; it also supports the evaluation and analysis of bottle body integrity, compressive resistance, and burst resistance. Additionally, it allows for the quantitative measurement of various parameters for flexible tubes, including overall sealing performance, pressure resistance, cap-to-tube connection strength, cap detachment strength, heat-seal edge strength, and crimp strength. Product Features:
