Aluminum foil is made from an aluminum alloy which contains between 92 and 99 percent aluminum. Usually between 0.00017 and 0.0059 inches thick, foil is produced in many widths and strengths for literally hundreds of applications. It is used to manufacture thermal insulation for the construction industry, fin stock for air conditioners, electrical coils for transformers, capacitors for radios and televisions, insulation for storage tanks, decorative products, and containers and packaging. The popularity of aluminum foil for so many applications is due to several major advantages, one of the foremost being that the raw materials necessary for its manufacture are plentiful.

Applications for heat seal aluminum foil include:
Blister Packs: Designed for product protection, opening convenience and consistent high quality. Pharmaceutical applications include preservation and freshness of products, safety and user-friendliness.
Medical: Foils used in a variety of medical and pharmaceutical applications: Pills, capsules, tablets and other medical lab needs. Protective aluminum shields from moisture, light, oxygen and contaminants.
Foil heat seals are one of the common ways to provide tamper-free evidence, leak prevention, freshness retention, heat reflection and more. If your packaging application requires sturdy seals, or if you need to seal something against the elements, foil heat sealing might be right for you.
How does Aluminium foil reflect heat?
Aluminum foil reflects heat because it's shiny and metallic. That is, it reflects thermal infrared radiation and does not emit much; it has a low Emissivity . It's shiny because metals have delocalised electrons; see Why are metals shiny? Heat is transmitted by conduction, radiation, and convection.
