In the European A8011, 1235Aluminium Foil for Pharmaceutical industry is used a blister film made of hard aluminium foil with a thickness of about 25 micrometers (μ). If the drug is to be taken, it can simply be pushed through the hard aluminium. The hardness of the film facilitates the so-called push-through opening.
Blister packs are often used for medicines in the A8011, 1235Aluminium Foil for Pharmaceutical industry. These consist of the so-called push-through Blister (or shorter “Blister”), a moulded plastic with cavities for the individual tablets, and a push-through closure made of aluminium foil, which is called blister film or lid film. As a result, capsules and tablets are hygienically clean and protected.
Blister packs are easy to handle, compact and easy to carry. In them, thanks to the aluminium foil, each product is individually packaged and protected against all influences until it is consumed.
A8011, 1235Aluminium Foil for Pharmaceutical Both soft and hard aluminium foils are used for the cover foils of the push-through packaging.
Traditionally, a hard aluminium foil is used. This has only a small stretching force. This has the advantage that you can break relatively quickly and release the drug with a relatively low force.
If, on the other hand, a soft aluminium foil is used, more force must be applied to reach the drug because the film has a higher stretching force. Thus, a blister packaging with a cover foil made of soft aluminum is considered to be more child-resistant.
