After cold stamping, it can replace the PTP blister packaging of the PVC part. Cold-formed foil is the composite aluminum foil with the best barrier properties, which is waterproof, oxygen-proof and UV-proof. It is used to package medicines, especially highly hygroscopic or light-absorbent medicines, which can greatly improve the protection of medicines (tablets, pills, capsules) and extend the shelf life.[/SIZE][/FONT][IMG]https://www.hwpfp.com/wp-content/uploads/2024/10/alu-alu-foil-packaging-1.jpg" alt="alu-alu-foil packaging " width="700" height="467" style="box-sizing: border-box; vertical-align: middle; border-style: none; max-width: 100%; overflow: hidden; text-align: center;[/IMG]alu-alu-foil packaging[/SIZE][/FONT]Alu alu foil packaging structure[/FONT]Cold-formed pharmaceutical packaging structure: biaxially oriented nylon film BOPA, outer printing layer, aluminum foil substrate (AL), polyvinyl chloride PVC, inner printing layer, adhesive (VC), etc., to protect the contents from moisture, light and oxygen.[/SIZE][/FONT]Aluminum foil thickness for aluminum-aluminum packaging[/FONT]The thickness of aluminum foil used in aluminum-aluminum packaging is usually 6 microns to 60 microns. The exact thickness depends on the specific application, product sensitivity and required protection.[/SIZE][/FONT]9-11 micron aluminum foil:[/FONT]Features: Good moisture barrier and sealing properties, can effectively protect the packaged goods from the external environment.Applications: Widely used in food packaging (such as tablets, candies, chocolates, etc.) and pharmaceutical packaging to ensure the freshness and safety of the product.[/SIZE][/FONT]18-25 micron aluminum foil:[/FONT]Features: Good thermal insulation and strength, suitable for packaging that requires a certain degree of durability and protection.Applications: Commonly used in building insulation materials, automotive sound insulation materials, and packaging for some electronic products and printing industries.[/SIZE][/FONT]45-50 microns:[/FONT]General pharmaceutical packaging: For standard tablets, capsules and blister packages that require moderate protection.â Provides sufficient moisture and light barriers for most pharmaceuticals.[/SIZE][/FONT]50-60 microns:[/FONT]Sensitive pharmaceuticals: Suitable for pharmaceuticals that are highly sensitive to moisture, light and air, such as pharmaceuticals that require a longer shelf life.Thicker foils in this range are stronger and provide enhanced mechanical protection and barrier properties.[/SIZE][/FONT]60 microns and above:[/FONT]Specialized packaging: For particularly sensitive products or those that require extra strength and puncture resistance. This can be used for pharmaceuticals and high-value foods.â Provides the highest level of protection and is more durable under extreme storage conditions.[/SIZE][/FONT]Factors affecting foil thickness selection:[/FONT]Product sensitivity:[/FONT]The higher the sensitivity to moisture and oxygen, the thicker the foil needs to be.[/SIZE][/FONT]Barrier properties[/FONT]Thicker foils generally offer better protection against moisture, light and gases, which is critical to extending the shelf life of your product.[/SIZE][/FONT]Packaging design:[/FONT]Depending on whether the package is a blister or pouch, foil thickness may vary to maintain form factor while ensuring adequate protection.[/SIZE][/FONT]Cost:[/FONT]Thicker foils are more expensive due to the greater material usage, so thickness is often chosen to balance cost-effectiveness with the protection required for a specific product.[/SIZE][/FONT]Additional layers:[/FONT]In addition to the foil, aluminum packaging often includes plastic films such as PVC or PP, whose thickness also affects the overall barrier properties. These plastic layers add flexibility and strength, while the foil provides the core barrier.[/SIZE][/FONT]For most pharmaceutical applications, 5 to 60 microns is the standard foil thickness for aluminum packaging. It provides excellent protection against external factors such as moisture, light and air, ensuring product stability and a long shelf life.[/SIZE][/FONT] https://www.friendbookmark.com/blogpost/45575/what-structure-of-aluminum-cold-foil-is-suitable-for-pharmaceutical-packagingCold-formed pharmaceutical packaging[/FONT]Aluminum foil is a good pharmaceutical packaging material, while cold-formed aluminum foil is a pharmaceutical packaging material with more outstanding performance. For pharmaceutical packaging, the aluminum cold foil commonly used is a laminated structure that combines the protective properties of aluminum with additional layers to achieve functions such as barrier protection, printability, and sealing.[/SIZE][/FONT]Cold-formed structure suitable for pharmaceutical packaging[/FONT]Typical cold foil structure for pharmaceuticals, standard aluminum cold foil for pharmaceutical packaging may consist of the following layers:[/SIZE][/FONT]a. Polyester (PET) film layer (12â25 microns)[/FONT]â Purpose: used as a base carrier film to provide mechanical strength and printing surface.[/SIZE][/FONT]â Features: high dimensional stability, smooth printing surface, good tear resistance.[/SIZE][/FONT]â Thickness: 12â25 microns, depending on the requirements for flexibility and strength.[/SIZE][/FONT]b. Adhesive layer (1â3 microns)[/FONT]â Purpose: bond polyester film to aluminum foil.â Features: Heat activated adhesive or pressure sensitive adhesive that ensures a secure bond without compromising the barrier properties of the foil.[/SIZE][/FONT]c. Aluminum foil layer (6-9 microns)[/FONT]â Purpose: Acts as the primary barrier layer to protect the drug from moisture, light, oxygen and other contaminants.â Features: High barrier to gases and moisture, light reflective and non-toxic.â Thickness: 6-9 microns (7mic,9mic)is the standard thickness for cold foil applications for pharmaceuticals.[/SIZE][/FONT]d. Heat seal coating/primer layer (1-5 microns)[/FONT]â Purpose: Provides a surface that can be heat-sealed to blister packs or other substrates.â Features: This layer is compatible with the sealing layer of PVC or PVDC blister films. It ensures a secure seal without affecting the drug inside.â Type: Typically a heat seal lacquer or primer that adheres well to PVC, PVDC or other common blister substrates.[/SIZE][/FONT]Enhanced cold foil structure[/FONT]In some cases, aluminum cold foil may have additional layers for better performance:[/SIZE][/FONT]e. Protective coating (optional, 1-2 microns)â Purpose: Enhance the abrasion and chemical resistance of the foil.â Features: Provide an additional barrier, especially important for highly sensitive pharmaceuticals.[/SIZE][/FONT]Key to cold aluminum for pharmaceutical packaging[/FONT]Cold-formed aluminum foil as the outer packaging of pharmaceuticals needs to have the characteristics of protecting the pharmaceuticals and blocking external factors, so the key considerations for pharmaceutical cold foil packaging are four aspects:1. Barrier: The aluminum foil layer provides an excellent barrier against moisture, oxygen and UV rays to protect the stability and efficacy of the drug.2. Printability: The PET film layer enables high-quality label and brand printing, which is critical for regulatory compliance and product identification.3. Compatibility: The structure must be compatible with pharmaceutical packaging machines and meet regulatory requirements (e.g. FDA, EMA).4. Sealing performance: The heat-seal coating must ensure a strong seal with the blister packaging substrate (e.g. PVC, PVDC-coated PVC or Aclar laminate).[/SIZE][/FONT]Typical cold foil thickness range:[/FONT]â PET film: 12â25 micronsâ Adhesive layer: 1â3 micronsâ Aluminum foil: 6â9 micronsâ Heat seal coating: 1â5 microns[/SIZE][/FONT]This structure achieves a balance between barrier protection, printability and sealing efficiency. Cold-formed aluminum is very suitable for pharmaceutical packaging materials due to its orderly structure, excellent ductility, excellent barrier properties, good sealing properties and many other advantages.[/SIZE][/FONT]
