Aluminum Foil Thickness Guide

Aluminum Foil Thickness Guide

Thickness of Aluminum Foil Explained

When you shop for foil, you might notice numbers on the box. These numbers show the aluminum foil thickness. You will see measurements in microns (µm), millimeters (mm), inches, or sometimes gauge. Each unit tells you how thick or thin the foil is. Most household foil falls between 16 and 24 microns. Heavy-duty foil is thicker, usually between 25 and 40 microns. Some industrial foils can go up to 200 microns.

Here’s a quick look at how these measurements compare:

TipoEspessura (mm)Espessura (µm)In cmFormulários
Folha de alumínio para uso doméstico0.016 mm16 µm0.0016 cmFood wrapping, cooking, everyday use
Heavy Duty Foil0.024 mm24 µm0.0024 cmBBQ, grilling, oven cooking
Industrial Foil0,03-0,20 mm30–200 µm0.003–0.02 cmInsulation, packaging, battery, pharma

You might also see foil labeled as “standard duty,” “heavy duty,” or “extra heavy duty.” These names match the thickness and the job the foil can handle. For example, ultra-thin aluminum foil is great for wrapping sandwiches or covering leftovers. It bends easily but can tear if you wrap sharp foods. Medium-thickness aluminum foil works well for baking or covering dishes in the oven. It gives you a balance between flexibility and strength.

Thicker foil means more strength. If you want to grill or roast, you need foil that will not rip when you fold it or wrap heavy foods. Thicker foil also blocks more air, moisture, and light. This helps keep your food fresh and safe.

Tip: If you want to avoid leaks or tears, pick a thicker foil for tough jobs like grilling or freezer storage.

Measuring Aluminum Foil Thickness

You may wonder how companies measure aluminum foil thickness. Most use microns, mils, or gauge. One mil equals 25.4 microns. In the U.S., you often see mils or inches. In other places, microns are more common.

Here are the main ways you might see thickness listed:

  • Microns (µm)
  • Mils
  • Inches
  • Gauge

Manufacturers use special tools to check the thickness. Some use simple models that measure how much energy passes through the foil. Others use advanced machines to check for evenness and strength.

Check out this table to see the typical thickness ranges for different types of foil:

Type of FoilTypical Thickness Range (Microns / µm)Typical Thickness Range (mm)Usos comuns
Standard Household Foil16 – 24 µm0.016 – 0.024 mmFood wrapping, baking, covering containers
Heavy-Duty Foil25 – 40 µm0.025 – 0.040 mmGrilling, oven bags, freezer wrap
Industrial/Converter Foil6 – 200 µm (or more)0.006 – 0.200 mmPackaging, insulation, electronics

Ultra-thin aluminum foil is easy to fold and shape, but it can tear if you use it for heavy foods. Medium-thickness aluminum foil gives you more durability. It stands up to heat and pressure better, so you can use it for baking or roasting.

Thicker foil costs a bit more, but it gives you better protection. It keeps out air and moisture, which helps your food last longer. Some new foils even have special coatings that stop food from sticking and make cleanup easier.

Observação: If you want to store food in the freezer or cook on the grill, always choose a thicker foil. For simple wrapping or covering, a thinner or medium-thickness aluminum foil will do the job.
