Aluminum Foil Thickness Guide: Household vs Commercial vs Industrial
Aluminum foil ranges from 6-micron household wrap to 200-micron industrial foil. Thickness determines strength, barrier properties, and suitability. This guide covers the full spectrum.
Household Foil: 6-20 Microns
Standard foil is 10-12 microns for food wrapping and light grilling. Heavy-duty at 15-20 microns offers better puncture resistance and heat tolerance. Ultra-thin 6-8 microns used in developing markets and laminated packaging.
Commercial Foil: 20-80 Microns
Restaurant containers use 30-50 micron foil for rigidity. Foil lids for yogurt, pharmaceutical blisters, beverages use 30-65 microns. Catering trays range 45-80 microns depending on size and load requirements.
Industrial Foil: 80-200+ Microns
Battery foil uses 10-20 microns with extreme surface quality. Capacitor foil 60-150 microns. Heat exchanger foil 80-150 microns with hydrophilic coatings. Cable shielding 80-150 microns. Aerospace insulation 100-200 microns.
Tolerance and Quality
Standard tolerance plus/minus 5-10% for general grades, plus/minus 2-3% for precision. Measurement by micrometer, XRF gauging, or gravimetric. Quality parameters include surface cleanliness, pinhole count, tensile strength.
Choosing Thickness
Food wrapping: 10-15 microns. Containers and lids: 30-50 microns. Industrial barriers: 80-150 microns. Structural/aerospace: 150-200+ microns. CoreMetal supplies 6-200 microns with full certification.
