Home Alucoat® cs

bobina-alucoat-cs-introAlucoat® cs is the designation of ALUCOAT for the lacquered foil intended to be used for the production of semi-rigid containers for food packaging. Due to its unique properties, Alucoat® cs coils are ideal for the reduction of cooking time, cooling and heating, thanks to an excellent thermal conductivity. Besides it provides a high barrier protection for light, gas and contamination, that improves the food conservation.
Its main advantages are:

  • Decorative potential, can be printed.
  • Extraordinary properties for inlaying, with lacquers especially developed by our technical department for single inlay process as well as double inlay.
  • Good mechanical protection and light weight, that allows to economizing on storage and transport.
