How to Control Pinholes of Pharmaceutical Foil

Pharmaceutical blister packaging is widely used in the pharmaceutical industry due to its beautiful appearance, good barrier properties and portability. It is currently the most important packaging for solid dosage forms such as pharmaceutical tablets and capsules.

Pharmaceutical foil(usually called PTP aluminum foil) is one of the two major constituent materials of this packaging method, and its pinhole degree will directly affect the protection of the final packaging to the contents.

Because if the PTP aluminum foil pinhole is just in the blister, it means that the medicine is in direct contact with the outside air, and the protective function of the medicine packaging will be completely lost, which will bring great risks to the manufacturers and users of the medicine.

There are two reasons for the pinholes of blister foil: 1. The pinholes in the production process of aluminum foil jumbo roll; 2. The pinholes in the production process of PTP aluminum foil. Since the pinholes in the PTP aluminum foil production process are relatively easy to control and avoid, we should mainly focus on the pinholes generated in the production process of the raw material aluminum foil for PTP aluminum foil.

The pinhole control of pharmaceutical aluminium foil is a systematic project, which involves the three links of aluminum foil blank production, raw aluminum foil rolling, and PTP aluminum foil production. Effective quality control must be carried out on these three links to minimize the production of pinholes.

Haomei Aluminum keeps strict control of the whole aluminum foil manufacturing process. We will have a preliminary judge when we find he pinholes in the sample protection even if it is within the allowable range.

Once it is judged to be caused by the aluminum blank problem, the relevant batch of aluminum foil will be sampled more to better evaluate the overall pinhole condition. We also pay attention to the cleanness of the production equipment and ensure that no hard debris particles adhere to the equipment rollers. Welcome to leave message below to inquire blister foil.
