huawei aluminum make great effort to develop aluminum foil for pharmaceutical industry packaging

Almost aluminum products of opaque or high barrier composite material adapt aluminum foil as the barrier layer, because aluminum foil has high density crystal structure, which can prevent any gas with a wide range application. It is expected that the package used for blister materials will be about 60%~70% of the tablets and capsules in the future, and it is one of the most promising packaging materials.
At present, the quality of Chinese medicinal aluminum foil is far from that of imported aluminum foil. From the current domestic production of PTP pharmaceutical packaging enterprises reflect the actual situation, there are mainly two aspects of the following problems.

A pin hole Shuyuan, aluminium foil is not up to the requirements. The pinhole of aluminum foil is a penetrating property defect, which affects the barrier property of aluminum foil, especially for drug packaging. It is easy to make oxygen, water vapor and light penetrate through and reduce the efficacy of drugs. Drug foil in the national standard requires pinhole diameter is not greater than 0.3mm, the diameter of 0.1 ~ 0.33mm can not exceed 1 /m2, the current domestic aluminum foil rarely meet this standard.
Two, aluminum foil thickness is uneven, tensile strength is low. Because the thickness of aluminum foil are easy to cause in the process of coating machinery PTP aluminum foil adhesive coating production difficult to achieve the standard of coating weight range, thereby affecting the aluminum foil and PVC film hot pot strength. Because of the uneven thickness and low tensile strength, it is impossible to produce the broken foil after the tension is applied in the actual processing, which is not conducive to the normal production. These problems need to be paid attention by the raw material manufacturers.
Henan huawei aluminum production of 8011 aluminium foil quality has a guarantee, alpha aluminum foil production has 10 sets of sophisticated foil rolling mill equipment, to ensure stable production of pharmaceutical aluminum foil; pharmaceutical version smooth, production safety and health, and clean, uniform color, no pinhole spots, no pollution; bacteria and fungus a number of heavy metal detection, not more than zero point two five ppm, strict implementation of industry standards, to ensure the safety and health
