30 Micron Aluminium Foil for Lamination Industrial Applications
30 Micron Aluminium Foill is a ubiquitous material in manufacturing and industrial processes due to its lightweight, high durability, corrosion resistance, and formability. Thinner gauges of30micron Aluminium Foil (1.2 mils) are particularly well-suited for applications involving 30micron Aluminium Foil lamination techniques. This article will provide an in-depth look at the key properties and industrial uses of 30 micron 8079 Aluminum Foil.
What is 30 Micron 8079 aluminum foil?
30 Micron alu foill is produced by passing aluminum sheets between polished rolls to reduce the thickness. Gauge is the standard global measurement for foil thickness, with one micron (μm) equal to 0.001 millimeters or 0.000039 inches.
30 Micron alu foil refers to aluminum that has been rolled down to a thickness of 0.030mm or 0.0012 inches (1.2 mils). On the gauge scale, this equates approximately to a 3 gauge Alu foil for lamination thickness. At this ultra-thin dimension,Alu foil for lamination retains the key attributes of bulk aluminum yet gains enhanced flexibility and conformability ideal for foil lamination processes.
Properties of 30 Micron Aluminum Foil
Lightweight - Weighing only 1/10th as much as heavier gauges per square foot, 30 micron foil imparts minimal additional weight to laminated materials.
Flexible - The very thin gauge allows 30 micron foil to conform to complex contours, seams, and crevices during lamination without cracking or tearing.
Formable - It can be easily stamped, stenciled, die-cut or hot stamped during composite material production runs.
Corrosion Resistant - 30 micron foil still forms the protective aluminum oxide surface layer preventing rust formation even in thin gauge.
Heat Reflective - Its high thermal conductivity reflects over 80% of infrared radiation for applications requiring heat shielding properties.
Chemical Inertness - Aluminum resists degradation from exposure to alkalis, acids and other industrial chemicals.
Conductive - Excellent electrical conductivity at this gauge enables electrostatic applications.
Recyclable - Foil scrap can be recovered and remelted for reuse with minimal reprocessing costs.
These material attributes make 30 micron aluminum foil perfectly suited for applications involving the lamination and integration of foil onto or between other substrates. Its robustness in thin gauge expands usage options.
Aluminum Foil 30Micron Lamination Processes
Several industrial lamination techniques integrate 30 micron aluminum foil into composite materials:
Roll Lamination - Foil is fed continuously between hot rolls with an adhesive or polymeric film to bond onto paper, plastic or fabric substrates for moisture barrier properties.
Flat Bed Lamination - Sheets or continuous webs pass through heated platens applying even pressure to fuse layers together. Offers more containment of volatile emissions.
Autoclave Lamination - Applying heat and higher pressures cures thermoset adhesives for very high bond strengths required in composites like aircraft panels.
Co-extrusion Lamination - Combining multi-layer extrusion with a separate foil feeding line embeds foil within plastic sheeting in a continuous process.
Stitch/Seam Lamination - Used in textiles, ultrasonic or sewing stitches hold layers together during thermal bonding for breathability in sports apparel.
Cold Lamination - Does not require heat activation, ideal for delicate or heat-sensitive substrates like paper or foams using contact or pressure-sensitive adhesives.
The flexibility of 30 micron foil allows it to smoothly conform to other substrates through these lamination techniques without defects, yielding durable foil-composite materials for industrial applications.
