What is pharmaceutical aluminum foil packaging？

What is aluminium foil packaging?Medicinal aluminum foil packaging is a deep-processed product of aluminum alloy raw materials. The main raw materials are 8011 aluminum foil and 8021 aluminum foil of 8000 series. Widely used in pharmaceutical manufacturing plants for surface packaging of capsules, tablets, and other drugs. It has the advantages of good drug moisture-proof, light-proof, and sealing.

Types of aluminum foil for pharmaceutical

As a medicinal material, aluminum foil can be applied to various types of medicinal blisters.

Pharmaceutical aluminum foil packaging material

Aluminum foil, also called tinfoil, has a high molecular density, can isolate air and light, has good airtightness, and is very suitable for medicinal packaging materials. In addition, aluminum foil also has good rolling properties and is easier to produce and disassemble. When taking medicine, the aluminum foil paper will break open with a slight click, which is very convenient and can also ensure the hygiene of the tablets.

Why choose aluminum foil as medicine packaging?

At present, the packaging of medicines on the market, including some health food and medicine tablets and capsules, is more and more common in the form of blister (also known as blister packaging, referred to as PTP: PressThrough Packaging), and the packaging materials used are aluminum foil production and processing. completed. Modern pharmaceutical packaging requires packaging materials that are 100% waterproof, vapor-proof and light-tight, and this aluminum foil material can perfectly meet the packaging requirements when sealing drugs. As a material with complete barrier properties, medicinal aluminum foil is used more and more widely, and its market share is also increasing.

Pharmaceutical blister packaging features

Why are medicines packed in aluminum foil?Aluminum foil has many advantages, and it has great advantages when used as the packaging of pharmaceutical products, such as prolonging the storage time of medicines and allowing medicines to be packaged independently. The six advantages of Aluminum foil pharmaceutical are as follows:

1. The density of aluminum is low, and the aluminum foil is lighter.
2. Pharmaceutical glass packaging material is non-toxic and tasteless.
3. Pharmaceutical packaging blisters are safe for human health and have no pollution from medicines.
4. The surface is beautiful in color and can be printed.
5. Packaging pharmaceutical has a certain strength and ductility, easy to process.
6. Pharmaceutical packaging foil is wear-resistant, long-term use can effectively protect the packaged medicines.

How does aluminum foil become a foil blister?

The aluminum foil for pharmaceutical blister packaging is generally a multi-layer composite structure, which must have an aluminum foil layer, a printing layer, an adhesive layer, and some will also be compounded with PVC PVDC and so on. Take conventional blister aluminum foil as an example: the surface of “PTP” aluminum foil is composed of a protective layer/printing layer/aluminum foil layer/printing layer/adhesive layer. The most basic components must be a protective layer, aluminum foil layer, and adhesive layer. The covering material for the blister is basically aluminum foil, and the production of aluminum foil requires the combined operation of aluminum foil printing machine, coating machine, slitting machine, packaging machine, and other equipment to complete the whole production process.

The aluminum foil processed in the pharmaceutical packaging material industry is customarily called “original aluminum foil” or “original foil”. The original foil is made of electrolytic aluminum with a purity of more than 99% and is made by machine calendering.

Corrosion resistance of medicinal aluminum foil materials

The surface of the aluminum foil alloy can naturally form an oxide film. The formation of the oxide film on the aluminum packaging material can further prevent the continuation of oxidation. Therefore, medicinal aluminum foil has a certain degree of durability and resistance to air corrosion. By coating the surface with protective material or coating with PE, corrosion resistance can be provided and the medicine can be stored for a longer period of time.

Huawei pharmaceutical aluminum foil manufacturing process

The main production process of Huawei Aluminum’s medicinal aluminum foil is: billet inspection – billet rolling – split rolling – coil rolling – rolled finished product – slitting – furnace annealing – finished product packaging. During the production process, Huawei Aluminum has very strict control over the surface and performance, which mainly reflects the following points:
1: First of all, we must control the quality from the source and strictly inspect the raw materials.
2: In the rolling process, the surface quality of the product is controlled by controlling the clarity and roughness of the roll, the selection of rolling oil, reducing the viscosity of rolling oil, and controlling the operating speed of the machine.
3: During the cutting process of the product, ensure that the edges of the aluminum foil roll are neat when cutting, and ensure that there are no quality problems such as ruffles.
4: In the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the medicinal foil to ensure clean oil removal.
