By using casting and rolling embryos, adjusting the intermediate annealing process, and controlling the viscosity of lubricating oils and adjusting the degreasing device, GNEE has been able to produce 8011-based aluminium foils with a higher quality and higher tensile and breakage strengths than its previous products. PTP foil made of 8011 base material.
On this basis, through the optimisation and improvement of cold rolling, rolling and raw materials, the method of improving the surface quality and mechanical properties of 8011 aluminium foil for pharmaceutical packaging was studied.
