Definitions

  • the invention generally relates to treating industrial packaging material, and more particularly to a system and method for separating plastic and aluminium from industrial packaging material.
  • Laminated packaging is widely used as a packaging material for a range of products and is becoming an increasingly popular option for lightweight product packaging.
  • Laminated packaging usually refers to packaging using plastic and/or aluminum. It is used in packaging a wide range of consumer products including food, drinks, toothpaste, bags, pouches and cosmetic products.
  • the principal object of this invention is to provide a system for separating aluminum and plastic from industrial packaging material.
  • Another object of the invention is to provide a method for separating aluminum and plastic from industrial packaging material.
  • Yet another object of the invention is to provide a process for separating aluminum and plastic from industrial packaging material.
  • the invention provides a system for treating industrial packaging material, wherein the system comprises at least a chemical tank for treating at least industrial packaging material to separate aluminium and plastic, a dehydration unit for removal of at least one of excess water and moisture from industrial packaging material, and a plurality of rolls for retrieving aluminium and plastic from industrial packaging material.
  • the invention provides a method for treating industrial packaging material, wherein the method comprises treating industrial packaging material in at least a chemical tank for at least separating aluminium and plastic; dehydrating industrial packaging material using a dehydration unit; and retrieving aluminium and plastic using a plurality of rolls.
  • the invention provides a process, wherein the process comprises treating industrial packaging material in a chemical solution for at least separating aluminium and plastic; dehydrating industrial packaging material for removal of at least one of excess water and moisture; and retrieving at least aluminium and plastic from industrial packaging material.
  • FIG. 1 depicts a system for separating aluminium and plastic from industrial packaging material, according to an embodiment as disclosed herein.
  • the separated plastic and aluminium is dipped in the water tank 104.
  • the water tank 104 comprised 50-80 litres of plain water.
  • the water tank 104 comprises 70 litres of plain water.
  • the separated plastic and the aluminum are dried to retrieve plastic and aluminum separately.
  • the separated plastic and the aluminum are dried using the pinch roll and the drier, passed through the drum to finally retrieve plastic and aluminum separately on separate rolls.
  • the embodiments herein provide a process for treating industrial packaging material and more particularly to a process for separating aluminum and plastic from industrial packaging material.
  • the raw material is unwound which is in the form of a roll.
  • the unwound raw material is remolded to a predetermined shape.
  • the remolded raw material is treated in a chemical solution comprising a mixture of sulphuric acid and salt.
  • salt includes sodium chloride.
  • the chemical solution is 50-80 litres.
  • the chemical solution is a mixture in the range of 35kg to 45kg of sulphuric acid and 800g to 1200g of sodium chloride.
  • the chemical solution is 70 litres.
  • the chemical solution is a mixture of 40 kg of sulphuric acid and 900g of sodium chloride.
  • Plastic and aluminum are separated in the chemical solution.
  • the separated plastic and aluminum is further placed in water to remove any excess chemical solution retained in the separated aluminium and plastic.
  • water is 50 to 80 litres of plain water.
  • water is 70 litres of plain water.
  • the separated aluminum and plastic are dried to remove excess water and aluminum and plastic are retrieved separately.
