Qual 8000 a liga da série é mais adequada para folha de alumínio?
Para folha de alumínio, folha de alumínio para embalagens farmacêuticas, a seleção do material de base precisa levar em conta fatores como as propriedades de barreira, força mecânica, desempenho de processamento e custo da folha de alumínio. O material base da folha de alumínio deve ter excelente barreira contra umidade, barreira de ar, propriedades de proteção contra luz, and good thermal stability to effectively extend the shelf life of drugs. Além disso, the aluminum foil should have sufficient mechanical strength to withstand deformation during cold forming and good processing properties to ensure production efficiency and product quality.
Portanto, among the 8000 ligas em série, if you want to choose a material suitable for cold forming medicine foil, you need to comprehensively consider the physical properties, mechanical properties of the alloy and its performance in specific application scenarios. 8021 aluminum alloy is considered more suitable for use For making cold-formed medicine foil.
Among the 8000 ligas de folha de alumínio em série, common alloy models are 8011, 8021, e 8079 folha de alumínio. These three alloys can be used as pharmaceutical packaging foils, e 8021 aluminum foil has more advantages in the application of cold-formed pharmaceutical foils.
1. Alloy characteristics: 8021 aluminum alloy has good forming performance, which is one of the key requirements for making cold-formed medicine foil. The alloy can be pressure-formed into precise pharmaceutical packaging shapes without the use of heat.
2. Faixa de espessura: The thickness range of 8021 aluminum alloy foil is usually between 0.04mm and 0.065mm. Aluminum foil of this thickness is suitable for cold forming process and can ensure the tightness and integrity of pharmaceutical packaging.
3. Surface quality: The surface of 8021 aluminum foil is smooth and free of bright lines and defects, which is very important for pharmaceutical packaging because it ensures the sealing of the packaging and the aesthetics of the product.
4. Desempenho de barreira: 8021 aluminum foil has high barrier performance and can effectively block moisture and oxygen, which is crucial for protecting drugs from the external environment.
5. Segurança: 8021 aluminum foil has a highly dense metal crystal structure, which provides a high degree of safety for highly hygroscopic or photosensitive drugs.
6. Wide range of applications: 8021 aluminum foil is not only used for pharmaceutical packaging, but also for food packaging and other fields that require high barrier properties.
7. Compliance: 8021 aluminum foil complies with regulatory requirements for pharmaceutical packaging, which is an important consideration for pharmaceutical manufacturers.
8021 aluminum alloy is an ideal choice for making cold-formed medicine foils due to its excellent forming performance, appropriate thickness range, good surface quality and barrier properties, as well as its wide range of applications and compliance.
