What Is Aluminum Foil?
Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It’s made by rolling large slabs of aluminum until they are less than 0.2 mm thick.
Commercial Aluminum Foil is used industrially for a variety of purposes, including packing, insulation and transportation. It’s also widely available in grocery stores for household use.
At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking.
People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them.
Lastly, it can be used to line grill trays to keep things tidy and for scrubbing pans or grill grates to remove stubborn stains and residue.
Cooking With Aluminum Foil May Increase the Aluminum Content of Foods
Most of your aluminum intake comes from food.
However, studies show that aluminum foil, cooking utensils and containers can leach aluminum into your food.
Temperature: Cooking at higher temperatures
Foods: Cooking with acidic foods, such as tomatoes, cabbage and rhubarb
Certain ingredients: Using salts and spices in your cooking
However, the amount that permeates your food when cooking can vary.
For example, one study found that cooking red meat in aluminum foil could increase its aluminum content by between 89% and 378%.
Such studies have caused concern that the regular use of aluminum foil in cooking could be harmful to your health. However, there is currently no strong evidence linking the use of aluminum foil with an increased risk of disease.
What Is Blister Packaging?
Polyethylene terephthalate (PET)
Polyvinyl chloride (PVC)
Polyvinylidene chloride (PVDC)
Polychlorotrifluoroethylene (PCTFE)
Cyclic olefin polymers (COP)
Blister packaging is manufactured from a plastic sheet that is thermoformed to create cups or blisters that hold a product in place. The packaging typically has a paperboard backing or a lidding seal of aluminum foil or plastic film.
Blister packs provide a safe, secure way to ship medicines and small consumer items, offering additional protection when goods are transported inside custom cardboard boxes. Each type of material used to create blister packaging offers something different.
