A complete instrumentation set for multilayer film, laminate and co-extruded film manufacturers — tensile, peel, dart impact, heat seal, thickness and conditioning across every layer combination.
Multilayer film gets its performance from a stack of thin layers, each doing a specific job: sealant, barrier, tie, structural. The whole structure only works if every layer is at the right thickness, bonded to its neighbours and contributes its share of strength.
This solution covers the mechanical, adhesion and seal tests that multilayer converters use to verify each new structure and each batch: tensile, peel between layers, dart impact, seal strength, GSM and thickness. Manufactured in Mumbai to ASTM and ISO standards.
Each card links to the machine that runs the test.
Tensile strength and elongation of multilayer film in machine and transverse directions.
Peel strength between laminated layers, and between sealed layers of the finished pouch.
Falling-dart impact failure weight of the multilayer structure.
Static and kinetic COF of the outer film surface for machinability and stacking.
Optimum seal temperature, pressure and dwell for the specific sealant layer.
Overall and layer-by-layer thickness verification against the design spec.
Substance weight of the laminate against the target grammage for cost and thickness.
Multilayer tests cover ASTM D882 (tensile), ASTM D903 / F88 & ISO 8510 (peel), ASTM D1709 & IS 2508 (dart), ASTM D1894 (COF), ASTM D6988 (thickness) and ISO 536 (GSM). We do not currently supply barrier (OTR/WVTR) instruments; every other multilayer QC test is covered.
