Most medicine packs have aluminium foil on one side & PVC on the other side. Some customers prefer to have the Holographic strips on the aluminium side of the blister. These strips are also applied through an off-line process. The customer can choose to do this operation in-house or Shriram Veritech can apply these strips at it’s facility. The same holographic strips can be used on alu-alu pharma packs as well as glassine paper pharma packs.
