ALU-ALU BASE FOIL

ALU-ALU BASE FOIL (COLD FORMING BLISTER FOIL)

Cold Forming Blister Foil is tremendous multifaceted arrangement planned for high responsive series of Pharmaceutical and generic medicines which are extremely hygroscopic or light responsive and cannot be rightfully packed with barrier plastic films. The composition is an optimized amalgamation of aluminium foil and polymeric films with the alumina sheet packed in amid an interior heat sealable polymeric film and external kind malleable film.

Benefits:

100% Barrier against water vapour, gases, light etc

  • Superb Thermoform ability
  • High level of Thermal stability
  • High Malleability for deep drawing blister cavities
  • Sealable with regular Vmch based aluminium Foil
  • Valuable anti counterfeit packaging
