1100 Aluminum Foil Jumbo Rolls
1100 aluminum foil belongs to the 1xxx series of industrially pure aluminum foils; it is rolled from a base material of pure aluminum with an aluminum content of ≥99.00%. Optimized through the addition of trace amounts of copper, this material significantly enhances mechanical strength and resistance to deformation while retaining the excellent corrosion resistance, electrical and thermal conductivity, and processing characteristics of pure aluminum. Consequently, it serves as a versatile industrial aluminum foil material that strikes an optimal balance between performance and cost.

FAQs
Can 1100 foil be used for food contact applications?
Food-grade compliant 1100 aluminum foil can be used for food packaging. It has stable chemical properties and does not release harmful substances under normal usage conditions. However, it must pass food-contact safety testing, including heavy metal migration and other relevant regulatory requirements.
What should be considered during processing of 1100 foil?
Although it has excellent formability, processing should be properly controlled: avoid excessive stretching to prevent tearing; control stamping pressure to prevent wrinkling; and use appropriate pure aluminum welding processes, avoiding excessive heat that may affect material properties.
What are the storage requirements for 1100 foil?
It should be stored in a dry, well-ventilated environment, away from acidic or alkaline corrosive substances. During stacking, heavy pressure should be avoided to prevent deformation. For long-term storage, moisture-proof packaging is recommended to reduce exposure to humid air.
How is 1100 foil recycled?
1100 aluminum foil has a high recycling rate. It can be remelted into aluminum ingots and reused for producing new aluminum foil or other aluminum products. This enables resource recycling and provides both environmental and economic benefits.
