It is often used t make the inner layer of food container lids to protect the freshness of food and prevent external contamination.

Aluminum foil alloys for food container lids

Pure aluminum is a soft, luz, e material metálico fácil de procesar con boa resistencia á corrosión e condutividade térmica. Adoita usarse para facer a capa interna das tapas dos recipientes de alimentos para protexer a frescura dos alimentos e evitar a contaminación externa..

Ademais de aluminio puro, aliaxes de aluminio de uso común inclúen aliaxes de aluminio-silicio, aluminum-magnesium alloys, and aluminum-titanium alloys. These alloys have higher strength and hardness while maintaining good corrosion resistance and thermal conductivity, so in some special cases, these alloys can be selected to make food container lids.

Alloy model using aluminum foil for food container lids

• 3003 papel de aluminio: It has good formability and strength, and is suitable for making deep-drawn food container covers.
• 8011 papel de aluminio: It has good formability, dureza, and corrosion resistance, and is a common material for making food container lids.
• 5052 Papel de aluminio: It has high strength and corrosion resistance, and is suitable for making large food container lids.
