Professional aluminium blister foil manufacturers

Professional aluminium blister foil manufacturers Haomei aluminum have over 20 years experience in supply aluminum blister foil for pharmaceutical packaging. As used in medical industry, the quality requirement of medicine aluminium blister foil is more strict than ordinary industrial aluminium foil.

With service customers all over the world, Haomei has focus the quality assurance on the following aspects:

1, Surface wetting properties

The appearance of aluminium blister foil should not have oil stain and poor wettability, which will not only affect the clarity and integrity of printing, but also cause color loss, affect coating quality, and reduce the protective agent adhesive, affects the sealing performance of aluminum foil and composite materials, and reduces the safety of pharmaceutical packaging.

2, Thickness deviation

The thickness of aluminum blister foil should be even, if the deviation exceeds the required (10%), it affects the tightness of the finished aluminum foil and the flatness, and also affects the packaging quality, and has an influence on the amount of the adhesive layer.

3, The alloy quality

Control the metallurgical quality of the billet, such as alloy composition, grain size, hydrogen content, slag amount, etc., to ensure the mechanical properties and pinhole porosity of the medicinal aluminum foil for blister.

4, The process environment

In the process of cold rolling and aluminum foil rolling, ensure that the production environment is clean and the air is clean. The air circulation filtration system is arranged in the workshop of  aluminium blister foil manufacturers to maintain the micro-positive pressure production, improve the surface quality of the medicinal aluminum foil and reduce the pinhole rate.

5, The rolling process

During the aluminum foil rolling process, the guides of the rolls, the arches, and the entrances and exits should be cleaned in time to prevent the incorporation of sticky aluminum and foreign matter.
