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, māmā, a me ka mea metala maʻalahi me ka pale ʻana i ka corrosion maikaʻi a me ka conductivity thermal. Hoʻohana pinepine ʻia e hana i ka ʻāpana o loko o nā poʻi pahu meaʻai e pale i ka hou o ka meaʻai a pale i ka ʻino o waho..

Ma waho aʻe o ka alumini maʻemaʻe, ʻO nā alumini alumini i hoʻohana mau ʻia me nā alumini-silikona, 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 alumini pepa: It has good formability and strength, and is suitable for making deep-drawn food container covers.
• 8011 alumini pepa: It has good formability, ʻoʻoleʻa, and corrosion resistance, and is a common material for making food container lids.
• 5052 Aluminum Foil: It has high strength and corrosion resistance, and is suitable for making large food container lids.
