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, ແສງສະຫວ່າງ, ແລະວັດສະດຸໂລຫະທີ່ງ່າຍຕໍ່ການປຸງແຕ່ງທີ່ມີຄວາມຕ້ານທານຕໍ່ການກັດກ່ອນທີ່ດີແລະການນໍາຄວາມຮ້ອນ. ມັນມັກຈະຖືກນໍາໃຊ້ເພື່ອເຮັດໃຫ້ຊັ້ນໃນຂອງຝາຕູ້ໃສ່ອາຫານເພື່ອປົກປ້ອງຄວາມສົດຂອງອາຫານແລະປ້ອງກັນການປົນເປື້ອນຈາກພາຍນອກ..

ນອກເຫນືອໄປຈາກອາລູມິນຽມບໍລິສຸດ, ໂລຫະປະສົມອາລູມິນຽມທີ່ໃຊ້ທົ່ວໄປປະກອບມີໂລຫະປະສົມອາລູມິນຽມ - ຊິລິໂຄນ, 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 ແຜ່ນອາລູມິນຽມ: It has good formability and strength, and is suitable for making deep-drawn food container covers.
• 8011 ແຜ່ນອາລູມິນຽມ: It has good formability, ຄວາມທົນທານ, ແລະການຕໍ່ຕ້ານ corrosion, and is a common material for making food container lids.
• 5052 ແຜ່ນອາລູມິນຽມ: It has high strength and corrosion resistance, and is suitable for making large food container lids.
