New cold formed aluminum foil composite film packaging and conventional cold formed laminate

In traditional blister packaging, thermoformed plastic sheets hold and keep the drugs in multiple cups (blisters) in the required state. Cold formed blister packaging is made by dry adhesive lamination, sandwiching aluminum foil between PVC and nylon film. The thin-film laminate can be pressed into the die through the die without heating, and the use of aluminum increases the barrier of water and oxygen, thus extending the shelf life to the validity period of the product.

In the new aluminum foil composite film packaging, the unique polyester film replaces the traditional nylon and PVC, while retaining aluminum, because PVC and BON (biaxially oriented nylon film) are easy to emit in direct sunlight and high temperature. “Aluminum foil is a multi-layer structure, which can provide high safety for highly hygroscopic or photosensitive drugs and generic drugs, and can not properly package barrier plastic film. The structure is a combination of aluminum foil and polymer film, and the aluminum layer is sandwiched between the internal heat sealing polymer film and the external supporting malleable film.”
