Aluminum foil for functional packaging in the medical sector

Aluminum foils for blister or other medical packaging

Thanks to its various positive properties and easy-to-process consistency, aluminum foil is the perfect material for blister or other medical packaging. For medicines, it is very important that they have an air and oxygen barrier around them to protect them from external influences. Otherwise, tablets, capsules, powders or liquids can quickly lose their effectiveness. Thanks to the material's ability to be printed on, each medication can be individually labeled.

Personalized imprints can also be used. These are preferably used in care homes to make work easier and enable people to be more independent. It is also possible to print the name, expiration date and batch number on each pack. This means it can still be identified even without packaging.

Aluminum is versatile and can be used to form various types of packaging. These include classic blister packaging, packaging with closures, bags or strip packaging. Hard aluminum foil or soft aluminum is used to produce the individual packaging. The aluminum can be mixed to make the individual packaging more stable. For example with paper/PET.

Thanks to the use of aluminum, medicines are now not only packaged safely, but are also more space-saving and less expensive. It can also be shaped, coated and printed better than almost any other material.

Blister packaging

The most common form of medication storage is blister packaging. It is also known as push-through packaging.
There are different types of blister packs. One is the push-through blister with aluminum foil. This makes the tablets or capsules more difficult to push out. This is considered particularly childproof.

Hard aluminum foil

Another variant is with hard aluminum foil, which is easier to press on, which is particularly helpful for people with limited hands.

Coldform blister

In addition to blister packaging, there are also coldform blisters, which are also known as form packs. This type of packaging was specially developed for climatically difficult areas and sensitive medicines. It has the characteristic of low diffusion. As a desiccant is incorporated into the base of the pack, it is particularly suitable for areas with high humidity. This prevents tropical climates, for example, from rendering the medicine unusable after a short time.

Tubes

Aluminum can also make tubes easier to handle. The laminate tube is coated with an aluminum barrier layer. This protects the contents and makes dosing easier. It is also protected by a membrane that has to be broken through before the contents can be used. This ensures sealing and thus the freshness of the contents.

Sachets

Sachet bags are another type of packaging. They are also made of laminate and protected by a layer of aluminum. As this form is very robust, it is used to transport solid or liquid medicines. It is also used for storage, often in hospitals.

Stickpacks

Stick packs are suitable for single oral doses of liquid or powder. They have the perfect shape for easy ingestion. A notch makes it easy to tear open this single-use packaging and take the single dose.
