Aluminum – one of the most abundant elements found on earth – is extracted from bauxite and then refined to produce pure aluminum oxide called alumina.
It is a thin metal leaf made of aluminum, with a thickness of less than 0.2 mm. A standard household aluminum foil is around 0.016 mm in thickness, while a heavy-duty aluminum foil is typically 0.024 mm.
The foil is highly pliable, flexible, and heat-resistant, and it can be easily wrapped around food or other consumer goods.
It is generally made of pure aluminum; however, various aluminum alloys are being engineered to add to the aluminum foil for enhancing its strength and flexibility.
It is widely used for packaging of foods, pharmaceutical and chemical products, and cosmetics, as it protects the contents against heat, moisture, and microorganisms such as bacteria.
It is more sustainable compared to other forms of packaging such as plastic due to its recyclability and reusability.
Why Aluminum Foil Is Good for Packaging of Food Products
It is the ideal choice for food packaging, as it acts as a strong barrier to light and air and helps preserve food for a longer period of time.
It is lightweight and fully recyclable, and its common kitchen applications include covering baking surfaces and wrapping foods such as meat and fish to prevent moisture loss while cooking or grilling.
Commonly used foil containers are round foil pans, aluminum catering trays, three-compartment foil pans or trays, and aluminum foil steam tables.
These containers are designed according to various user requirements and are largely used at homes, catered events, and hotels and restaurants for food storage and packaging.
Besides containers, aluminum foil packaging is available in other forms such as house foils, laminated lids, chocolate foils, foil lined bags, and foil round seals.
Hence, this type of packaging has significant advantages over other packaging forms, such as better hygiene & safety, sustainability, assorted design, greater flexibility, and heat conductivity.
When wrapped around food while cooking, aluminum helps in even distribution of heat and accelerates the cooking process. Moroever, food-grade foil is sterile and aseptic and keeps the food fresh and contaminant-free.
Extensive Use of Aluminum Foil Packaging in the Pharmaceutical Industry
In the pharmaceutical industry, packaging is an indispensable part of the production process, and high-quality packaging of medicines ensures their safe storage and transportation from the manufacturing facility to drug store aisles.
Most common types of aluminum foil packaging for pharmaceutical products include push-through foils, heat seal lacquer, and blister cover foil.
Blister foil packs are the most widely used drug packaging and consist of blisters – which are plastic cavities made for holding the tablets – and push-through closures made of foil, commonly known as blister lids.
The blister foil packs are compact and easy to handle, and they keep the tablets and capsules clean and protected.
Both soft and hard aluminum foil can be used for drug packaging; hard foil requires lesser force to break and releases the drug relatively faster, while, soft foil requires greater force and is thus proven to be more child-resistant.
