What is cold form blister?
Cold form blister packs are manufactured by sandwiching aluminum foil between Polyvinyl Chloride (PVC) and nylon (oPA) films using dry bond lamination technology. The film laminate is simply pressed into a mold by a stamp without applying heat. Thus the material is called cold forming blister laminate.
Why Alu Alu packing?
Alu Alu foil is an excellent multilayered structure designed for highly sensitive range of pharmaceutical and generic medicines which are highly hygroscopic or light sensitive and cannot be suitably packed with barrier plastic films.

Why is PVC used in pharmaceutical strip foil?
The PVC film in alu-alu laminate is commonly used as the contact layer and seal to layer on pharmaceutical blister (as neutral layer for the goods to be filled). PVC is very stiff and does not tend to shrink or spring during cold forming. Once the cold forming process is complete, the PVC helps the cavity hold its shape.
Which is the best material for cold forming?
Once the cold forming process is complete, the PVC helps the cavity hold its shape. In short it ensures the geometric stability after cold forming. The nylon (OPA) film is mainly responsible for the multi-axial forming. Laminating the aluminum with the OPA film doubles the formability of the foil.
