Aluminium Foil Pharmaceutical Grade Material 8011

Aluminium Foil Pharmaceutical Grade Material 8011 packaging is currently the most widely used pharmaceutical packaging method. It has the advantages of moisture resistance, safety and hygiene, long shelf life, easy to carry and use, etc. Aluminum foil for pharmaceutical packaging generally consists of 5 parts: protective layer, outer printing, aluminum foil substrate, inner printing, and adhesive layer.
 (1) Modify the surface of the aluminum foil to make the surface of the aluminum foil bright and smooth, and fill the small gaps on the surface of the aluminum foil.
 (2) Improve the acid and alkali corrosion resistance of aluminum foil and prolong the shelf life of medicines.
 (3) It has certain hardness and adhesive strength, protects the printing ink on the outside, and adheres well to the aluminum foil substrate without falling off. When compounding at high temperature (150-180 ℃), the coating will not stick to the machine roller of the medicine packaging machine because of softening and stickiness. In this test, thermosetting acrylic resin is used, and by cooperating with appropriate nitrocellulose, additives, solvents, etc., to obtain medicine packaging with good heat resistance, strong adhesion, plump coating, rapid drying, good unwinding and excellent performance. Aluminum protective coating.
The important performance requirement of Aluminium Foil Pharmaceutical Grade Material 8011 protective coating is that the protective layer formed on the hard aluminum foil has a strong adhesion to the aluminum foil, and has high hardness during high temperature hot pressing compounding (150-200 ℃: ) without sticking. Nitrocellulose has good tensile strength, high hardness, and quick release of solvent. When its content reaches a certain level, it can meet the hardness requirements. Thermosetting acrylic resin is used as a protective or decorative coating on metal surfaces. After curing, it has excellent performance in all aspects, and has excellent gloss retention, color retention, corrosion resistance, heat resistance, and high adhesion. After comprehensively considering the properties of the two resins, nitrocellulose and thermosetting acrylic resin were selected as the main film-forming materials for the aluminum foil protective coating for pharmaceutical packaging to ensure that the protective layer has good hardness, adhesion, heat resistance and Corrosion resistance.
