Aluminium foil is widely accepted as being one of the best barrier materials in flexible packaging, even in the face of many new and up-and-coming high-barrier plastic layer combinations, copolymers, blends or nano-composites. Besides high thermal conductivity, which facilitates enhanced converting and sealing performance, other key criteria that distinguish “converter foil” from competing mate...

The fracture toughness of a polymer-metal laminate composite is obtained by mechanical testing of a specimen containing a pre-crack. The laminate is a material used for packaging. It consists of a thin aluminium foil and a polymer coating. A centre cracked panel test geometry is used. Each of the layers forming the laminate is also tested separately. The result is compared with the measured fra...

Two-dimensional staggered silver nanosheets (NSs) immobilized on a flat aluminium foil have been synthesized by keeping the underside surface of the foil in contact with the solution of normal silver mirror reaction. The NSs are hundreds of nanometres to several micrometres in dimensions and tens of nanometres in thickness. The effects of the aluminium foil, a chemically active substrate, on th...

The technically pure copper is being replaced by aluminium as conductive material in electrical transformers for power systems. This evolution brings new manufacturing challenges. One major difficulty is the limited weld ability and non-acceptable residual deformations of the aluminium, when welded by fusion arc welding processes. The Friction Stir Welding (FSW) was selected for evaluation cons...

We present a simple, rapid, benchtop, Foil Assisted Rapid Molding (FARM) method for the fabrication of microfluidic devices. This novel technique involves the use of aluminium foil, pen and an X-Y plotter to create semi-circular or plano-concave, shallow microchannels. It is an easy do-it-yourself (DIY) technique for creating a microfluidic device in three simple steps: (1) create a channel des...

Three methacrylate allergens, methyl methacrylate (MMA), 2-hydroxyethyl methacrylate (2-HEMA), and ethyleneglycol dimethacrylate (EGDMA), were purchased from Chemotechnique Diagnostics (Vellinge, Sweden). These were compounded in 2.0% wt/wt petrolatum (pet.) and inserted into capped polypropylene syringes (with and without aluminium foil wrapping) and IQ chambers (Chemotechnique Diagnostics) wi...

Electron Rutherford back scattering (ERBS) is a new spectroscopy for determining the composition of surfaces. In this work the surface sensitivity of ERBS was investigated by changing the entrance and exit angle of the electron beam while keeping the scattering angle constant. It was found that in this way the surface sensitivity of the technique can be varied considerably. We use aluminium as ...
