Alu Alu Cold Forming Foil
ALU ALU Cold Forming Foil is a high-end packaging material designed specifically for the pharmaceutical industry, widely used in the protection and packaging of medications. Unlike traditional thermoformed blister packaging, ALU ALU foil uses aluminum foil for both the cavity and lid materials, providing excellent protective and barrier performance.
What is alu-alu base foil?
Alu-Alu base foil is a type of aluminum foil packaging material used in the pharmaceutical industry, typically serving as the base layer in Alu-Alu cold forming blister packaging. It is processed using cold forming technology to create a cavity with excellent barrier properties, effectively blocking moisture, oxygen, and light, thus protecting the stability and efficacy of the medication.
What is the structure of Alu Alu cold forming foil?
ALU ALU foil typically consists of two layers of aluminum foil, one for the cavity and one for the sealing lid. These two layers of aluminum foil are processed using cold forming technology to create a sturdy blister structure. Cold-formed aluminum foil forms various shapes and sizes of cavities to store medications by applying pressure without high-temperature heating. Due to the nature of aluminum foil, it can create a sealed protective environment, effectively isolating harmful external factors.
ALU ALU foil is made of a multi-layer structure, usually composed of oriented polyamide (OPA), aluminum foil, and PVC film. These layers are stacked together using adhesives to form a strong and highly protective material.
- OPA film: 25 microns
- Adhesive: 4 g/m²
- Aluminum foil: 45-60 microns
- Adhesive: 4 g/m²
- PVC film: 60 microns
This multi-layer structure ensures that the foil has excellent barrier properties, mechanical strength, and flexibility.
Alu Alu Cold Forming Foil Cold Forming Process
Compared to thermoformed blister packaging, the advantage of cold-formed aluminum foil is that it does not require high-temperature heating to form. The cold forming process allows aluminum foil to create detailed and complex blister shapes at lower temperatures, while maintaining its excellent barrier properties. This process ensures the integrity of the foil without thermal damage.
The forming process of ALU ALU foil involves cold forming, where high pressure is applied to create cavities in the aluminum foil. This process does not involve heating, making it suitable for sensitive products.
Alu Alu Cold Forming Foil Advantages
Excellent Barrier Performance
ALU ALU foil offers outstanding barrier performance, effectively blocking moisture, oxygen, light, and other harmful external factors. This ensures that medications maintain their stability and efficacy over time. This is especially important for drugs that are highly sensitive to moisture and oxygen, such as certain antibiotics, vitamins, and hormones, as ALU ALU foil provides exceptional protection.
- Moisture resistance: ALU ALU foil effectively isolates moisture in the air, preventing drugs from absorbing moisture and deteriorating.
- Oxygen resistance: It blocks the entry of oxygen, preventing drugs from degrading due to oxidation reactions.
- UV resistance: The aluminum foil itself has excellent light resistance, blocking ultraviolet rays and preventing light-induced degradation of the drugs.
Unmatched Protection
ALU ALU foil provides unmatched protection by preventing moisture, oxygen, light, and other external factors that could damage medications. Its packaging structure can effectively extend the shelf life and stability of drugs, ensuring they are not affected by environmental factors during transportation, storage, and use.
Alu Alu Cold Forming Foil Applications
ALU ALU foil (aluminum-aluminum foil) is a packaging material made by cold-forming two layers of aluminum foil, widely used in applications that require high barrier performance and protection. Its unique structure and properties make it especially suitable for products with strict environmental requirements, such as pharmaceuticals, nutritional supplements, and cosmetics.
| Application | Description |
| Solid Medications (e.g., tablets, capsules) | ALU ALU Cold Forming Foil is widely used in the packaging of solid medications, especially tablets and capsules. Its dual-layer aluminum foil structure provides excellent barrier properties, effectively preventing the intrusion of moisture, oxygen, UV light, and other environmental factors, thus maintaining the stability of the medication and extending its shelf life. By providing high-level protection, ALU ALU Cold Forming Foil ensures that the medication remains unaffected during transportation and storage. |
| Sensitive Medications (e.g., vitamins, hormones, antibiotics, vaccines) | ALU ALU Cold Forming Foil has significant advantages in packaging sensitive medications such as vitamins, hormone drugs, antibiotics, and vaccines. Its outstanding barrier properties prevent the intrusion of oxygen and moisture, avoiding degradation of the medication's components, ensuring the stability of active ingredients, and extending the shelf life. For temperature- and humidity-sensitive medications, ALU ALU Cold Forming Foil provides additional protection, reducing the risks posed by environmental changes. |
| High-Value Medications (e.g., low-dose, high-value drugs) | Due to the high barrier properties offered by ALU ALU Cold Forming Foil, it is highly effective in packaging high-value, low-dose medications. These drugs are often expensive and particularly sensitive to environmental changes. ALU ALU Cold Forming Foil ensures that the medication retains its efficacy during storage and transportation, preventing oxidation, hydrolysis, or other degradation of the components, thus maximizing the quality of the medication. |
| Nutritional Supplements (e.g., vitamins, mineral supplements) | ALU ALU Cold Forming Foil is also widely used in packaging nutritional supplements, especially those containing active ingredients such as vitamins and mineral supplements. Since these products are prone to moisture, oxidation, or degradation, ALU ALU Cold Forming Foil effectively blocks external oxygen and moisture with its dual-layer aluminum foil structure, ensuring the stability and efficacy of the supplements, extending shelf life, and ensuring consumers receive high-quality and safe nutritional supplements. |
| Cosmetics (e.g., sensitive cosmetics, skincare products) | ALU ALU Cold Forming Foil is commonly used in the packaging of sensitive cosmetics and skincare products, especially those containing easily degradable ingredients such as anti-aging components, vitamin C, and retinol. These ingredients are susceptible to light, air, and humidity, and ALU ALU Cold Forming Foil offers excellent gas and light barrier properties, preventing the degradation of active ingredients, ensuring skincare efficacy, and extending the product's shelf life. |
| Medical Devices (e.g., disposable devices, sterile equipment) | ALU ALU Cold Forming Foil also plays a critical role in the packaging of medical devices. For medical instruments that require a sterile environment (e.g., surgical instruments, disposable syringes), ALU ALU Cold Forming Foil provides a high level of protection, effectively isolating air, moisture, bacteria, and other external contaminants, ensuring the sterility and shelf life of the products. By preventing the influence of external factors, ALU ALU Cold Forming Foil ensures that medical devices can be used safely and efficiently. |
