  • Aluminium Foil - an overview ScienceDirect Topics

    ·

    Aluminum foil has long been used as a barrier layer in flexible packaging. The production of aluminum foil begins with a series of cold roll steps where the thickness of an aluminum ingot is reduced in half with each step. In the final step below 60 μm, the foil is doubled over and sprayed with oil (for release). The foils are rolled together to the final thickness, separated, rerolled, slit into the desired width, and

  • Bimetallic strip - Wikipedia

    A bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated. The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature.

    Aluminium foil is typically less than 150 µm in thickness. Foils are available in gauges as low as 6.3 µm.Heavier foil gauges (> 17 µm) provide an absolute barrier to gases and liquids.A typical water vapour transmission rate (WVTR) for 9 µm foil is 0.3 g/m 2 per 24. hours at 38 °C and 90% RH As thickness is reduced, foil becomes more vulnerable to tearing or pinholing.
