8011 aluminum foil and 8021 aluminum foil are both popular types of aluminum foils used for various applications, but they have some differences in their chemical composition and properties. Here’s a comparison based on key factors:

Composición de la aleación:

8011 Papel de aluminio: Es una aleación típica de la serie 8xxx y contiene aluminio como elemento principal con pequeñas cantidades de otros elementos como el hierro., silicio, y cobre.
8021 Papel de aluminio: También pertenece a la serie 8xxx y es una aleación que consta de aluminio como elemento principal., con elementos adicionales como el hierro, silicio, y otros oligoelementos.

Solicitud:

8011 Papel de aluminio: Este tipo de lámina se usa comúnmente en varias aplicaciones de empaque., como para el envasado de alimentos, envases farmacéuticos, y lámina doméstica.
8021 Papel de aluminio: It is specifically used for blister packaging in the pharmaceutical industry due to its excellent barrier properties against moisture, oxygen, and light.

Propiedades mecánicas:

8011 Papel de aluminio: It has good mechanical properties, making it suitable for general-purpose packaging requirements.
8021 Papel de aluminio: This foil has higher tensile strength and elongation compared to 8011 frustrar, which is crucial for blister packaging that requires easy formation and sealing.

Propiedades de barrera:

8011 Papel de aluminio: It provides a moderate barrier to moisture, luz, and gases, making it suitable for standard packaging needs.
8021 Papel de aluminio: Due to its enhanced barrier properties, it is an excellent choice for pharmaceutical blister packaging, protecting drugs from external elements.

Softness:

8011 Papel de aluminio: It has a relatively softer structure, making it easy to bend and fold for various packaging applications.
8021 Papel de aluminio: This foil is slightly harder than 8011, but it remains pliable enough to be formed into blister packs without compromising the barrier properties.

Cost:

8011 Papel de aluminio: It is generally more cost-effective compared to 8021 frustrar, making it preferable for cost-sensitive applications like household foil.
8021 Papel de aluminio: Being specialized for pharmaceutical blister packaging, it may be more expensive than 8011 foil due to its unique properties.
