Heat Seal Tester Applications: Industry-Specific Solutions for Packaging Integrity
Heat seal testing is required across four major packaging industries — each with distinct materials, standards, and failure-mode risks. KHT STH testers are validated for all four.
Pharmaceutical
Blister packs, sterile pouches, and lidstock for ISO 11607/USP <1207> compliance. Prevent microleaks that compromise patient safety.
Food Packaging
Lidstock SIT testing, snack bags, and flexible pouches per ASTM F88. Reduce recall risk by verifying seal integrity before production runs.
Flexible Film R&D
Map heat seal windows for PE, PP, EVOH, and BOPP multilayer films with the STH-3A 5-position gradient. Full seal curve in one ASTM F2029 test session.
Battery Pouch
Aluminum laminate film at 200°C, 22.5N/15mm specification. Gradient testing for top and side seals on lithium-ion pouch cells. GB/T and IEC 62133 aligned.
