For many years, pharmaceutical, medical device, and in vitro methods / point-of-care test kit manufacturers have relied on cold-form foils. Demand for cold-formed foils grows and develops as researchers continue to develop new ideas. Thorough knowledge of the requirements for these foils, how the best output is achieved, and how the requirements & material design interact with each other are all crucial to a successful final product. Here, we’ll look at cold-form foil specifications, package design (and manufacturing procedures) to see how they all interact to ensure that patients get the life-saving medications they need.
Aluminum Cold Forming Foils for Medical Purpose
Pharmaceutical capsules, sutures, & diagnostic fluids all benefit greatly from the use of Cold forming foil materials. Each application has its own unique set of needs. Still, in practically every case, package design considerations like oxygen & water resistance, physical product protection, sealability to a lid or any other device component, and simplicity of manufacturability play a role. Opacity (to protect from UV exposure), chemical stability, aesthetics, and simplicity of opening are just a few more needs that frequently arise. A thorough understanding of a product’s peculiarities will ensure that the package is geared to succeed in the marketplace.
Considerations for Material, Process, & Design
In the cold-forming process, the flexible protective coating’s local stretching (and thinning) occurs. A film’s thinning is influenced by its depth, cross-sectional area (or footprint), and the draught angle at which it is created. As a measure of cold-forming design, the draw ratio is the proportion of finished surface area (Af) to the initial cross-sectional area (As) (Ai).
- Depending on whether the packaging is in direct contact or not, Blister packaging falls into one of two categories: primary or secondary.
- There are two elements to the Blister: the Forming foil as well as the Cold forming foil, which are used to shape and seal the product inside the Blister.
- To ensure the quality of our goods, we perform stringent quality controls in each of our manufacturing facilities, starting with the raw material at the heart of Carcano: aluminum foil.
- Throughout our vertically integrated process monitored and inspected by the Quality Control Department because the aluminum ingot arrived, our aluminum foil fully counts for its traceability.
Because pharmaceutical aluminum packaging is developed in harmony with the product and the various ways, it provides the best possible functional & environmental performance for the pharmaceuticals it contains.
A sustained focus on science and innovation is bound to take for granted either rising stability or the expanding life cycle for aluminium blister foil medicines.
Using Cold Forming Foil for Best Results
- Light, moisture, oxygen, and other gasses are all kept out thanks to the robust barrier.
- The ability to mold in the cold
When working with cold forming, the best quality control measures are needed.
- Controlling the weight of adhesives and coatings can be done in-situ
- Remaining solvent concentrations and gram weights
- Elongation percentage of Blister’s delamination resistance to bending
- Strength in heat-sealing
Types of Aluminum Foil Cover
- Aluminized blister-cover foil
Push-through packaging is made of both hard and soft metal. Only hard aluminum foil was formerly utilized since it was easy to shatter and release the medicament without putting much effort into it. Soft aluminum foil is deemed child-resistant because of its high bending power and greater energy required to open. Using a lamination of metal with PET and paper can further enhance this effect.
- Hard metal is used to make the cover material.
The European pharmaceutical industry prefers strong aluminum foil with a thickness of around 25 micrometers. To administer the medication, insert it through the opening in the hard Aluminium foil for blister packaging. Printing is commonly used for the consumer-visible seal on the package’s exterior. Writings may also be etched into the lacquer sealant in some cases. A heat seal prime and a heat seal lacquer must be applied for a double coating. The primer is needed for the thermal seal lacquer to attach properly to the aluminum foil. For marketing purposes, some primers are colored. A heat sealing lacquer is applied in these situations once the primer has dried. The heat sealant can protect color pigments from the primer. Heat sealant lacquer & aluminum foil are sandwiched between the pigments. The prime, color pigments, and heat seal lacquer must be matched.
- Soft aluminum is used in the construction of the cover.
Soft aluminum can be used in the same way as hard aluminum foil. It is used to keep children from accessing tablets when necessary. It’s better because it’s soft & requires a great deal of force to open, making it ideal. The aluminum foil’s pliability and thickness make it more difficult for youngsters to open.
Lid film, also known as blister film, is a push-through closure made from aluminum foil. Finally, a clean, sterile environment is created for the pills and tablets. It’s easy to carry around and store in a Blister Pack.
