Different Types of Aluminum Blister Foils

Among the current packaging materials, aluminum foil has very good barrier properties. With this advantage, aluminum foil is widely used in various packaging materials. In the field of pharmaceutical packaging, blister foil can be used in PTP aluminum foil packaging, tropical blister packaging, cold stamping packaging and pharmaceutical bottle caps, and the requirements for aluminum foil are relatively high.

Tropical blister aluminum (aluminum-plastic aluminum) is a relatively high-end pharmaceutical packaging. It is a packaging form developed specifically to enhance the barrier properties of traditional aluminum-plastic packaging. \

After forming, the product is compounded on the PVC surface of the aluminum-plastic blister packaging to replace the moisture-proof bag. Tropical blister packaging mainly uses 8021 aluminum foil and 8079 aluminum foil.

The blister is sealed by PTP aluminum foil (top) and cold stamped aluminum (referred to as "cold aluminum", bottom) for packaging. Compared with the most common PVC material, it is an upgraded version of packaging. It has all the properties of PVC (easy to form and barrier properties).

Cold aluminum, because of the addition of aluminum foil properties, makes the barrier effect of the material 60 times that of PVC, and the stability of the packaged drugs is much better than PVC.

In addition, the sealing of cold aluminum and PTP aluminum foil does not require heating. For temperature-sensitive drugs, the temperature of PVC sealing will affect the quality of the packaged drugs.

PTP aluminum foil is mainly composed of multiple layers. The inner layer is usually high-purity medicinal aluminum foil(8011 aluminum foil), which has excellent moisture-proof and light-proof properties, effectively protecting the drug from the external environment and extending the shelf life of the drug. The outer layer is combined with an easy-to-open design, so that patients can easily open the package to take medicine without tools, which greatly improves the convenience and hygiene of use, especially suitable for the elderly with poor eyesight or weak hand strength.

In addition, the production process of "PTP aluminum foil" continues to improve. For example, the use of laser punching technology to accurately locate micropores on the blister not only ensures the air permeability requirements of the drug, but also effectively prevents foreign matter from invading and ensures the hygiene standards of the drug.

At the same time, with the increase in personalization and anti-counterfeiting needs, clear graphic information and anti-counterfeiting logos can also be printed on PTP aluminum foil, further enhancing the recognition and hygiene of drug packaging. Welcome to inquire ptp blister foil cost from us.
