Aluminium Blister Foil :

Aluminium blister foil is good barrier to moisture, vapour and gases and is suitable for high speed packing applications on rotary and flat bed blister packing machines.

The blister packs are in compact in size and economical, as compared to strip packs. Tablets can be removed easily from blister packs, as the hard foil breaks quickly when tablet /capsule is pressed from PVC side. Barrier properties of blister packs are comparitvely lower than strip pack due to usage of PVC film on one side.

We offer both unprinted and printed blister foil as per customers requirements with different foil thickness and heat seal lacquer grammage.

We also offer both side printed blister (also printed on HSL side of the foil), blister foil with Holograms for unique authentication of your product.
