Heat seal foil tapes offer a quick, cost effective and reliable method of effectively sealing microplates and wells, and channels in diagnostic devices. Heat sealing aluminium foil can be used under a wide temperature range, can be peelable, pierceable, solvent resistant and will adhere to a wide range of substrates.
Utilising our range of converting capabilities, we can customise aluminium heat seal foils into custom sheets, non-standard roll widths or die-cut shapes. We can also advise on presentations and assembly solutions.
Heat sealing foil applications:
Thickness range (mm)
D/S or S/S
Fluid resist backing
MVTR (gms/m2 /24 hrs)
Max width (cm)
Max length (m)
Manufacturer / SOS
