The KASON-LST400 Leak, Airtightness, 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 sterile packaging—specifically those formed through various heat-sealing or bonding processes. It also facilitates the analysis of material properties used in flexible packaging bags, such as compressive strength and burst strength. Furthermore, the instrument enables the quantitative measurement of sealing performance for various plastic tamper-evident bottle caps, cap-to-bottle detachment strength, and material stress strength; it also supports the evaluation and analysis of bottle body integrity, including airtightness, compressive resistance, and burst resistance. Finally, it allows for the quantitative determination of various parameters for flexible tubes, including overall sealing performance, pressure resistance, cap-to-tube connection strength, detachment strength, heat-seal edge strength, and crimp strength.
