A hydrometallurgical method was applied for aluminum extraction from laminated aluminum packaging films (LAPFs) waste. The leaching of LAPFs using hydrochloric acid solutions was used to separate aluminum from polyethylene plastic. Leaching behavior were examined with the effects of acid concentration, liquid/solid ratio and leaching time under fixed condition. 4isRSOY3gmxr Jan 20, 2016 · Approximately 46,000 t/day of packaging waste is generated in China, andposite packaging material (primarily PA-PE-Al laminate, a laminated foil made from paper, polyethylene and aluminum foil) is being used more and more for packaging juice, milk, food and medicine, because of its excellent barrier properties.

To protect the aluminum foil from tearing when assembling the barrier, insert a paper sheet between the iron and the foil, as shown in Figure 3. If the plastic sheet is thin, up to 3 layers may be needed. Plain aluminum foil is even more susceptible to scratches CS7HvSWbaLEr
