Is Mylar Food Safe?

When it comes to food storage, the material you choose can have a significant impact on the quality and longevity of your food. Among the many options available, Mylar bags have gained popularity for their effectiveness in preserving food. However, a common question arises Is Mylar food safe? In this article, we will delve into the properties of Mylar and explore whether it is a suitable option for food storage.

Mylar is a brand name for a type of polyester film known as BoPET (biaxially-oriented polyethylene terephthalate). This material is known for its durability, strength, and excellent barrier properties. Originally developed in the 1950s, Mylar has been used in various applications ranging from insulation in spacecraft to the production of balloons. Its versatility extends to food storage, where it has become a popular choice for packing long-term food supplies.

Properties of Mylar

One of the critical features of Mylar is its ability to effectively block light, oxygen, and moisture. These elements can contribute to food spoilage, making Mylar an excellent option for long-term food storage. By creating an airtight seal, Mylar bags can significantly extend the shelf life of dried foods, grains, and other perishables.

In addition to its barrier properties, Mylar is also resistant to punctures and tears, making it a robust choice for storage. Moreover, Mylar bags can be heat-sealed, ensuring that they remain airtight once filled with food items.

Food Safety

When it comes to Mylar and food safety, it's essential to consider the composition of the material. Mylar itself is made from polyester, which is generally recognized as safe (GRAS) for food contact applications. Many manufacturers produce Mylar bags specifically designed for food storage, ensuring that they are free from harmful chemicals that could leach into food.

However, it's crucial to choose high-quality Mylar bags that are labeled for food use. These bags are typically made without additives that could pose health risks. Avoid using Mylar bags that are intended for other purposes, as they may contain materials that are not food-safe.

Potential Concerns

While Mylar bags are considered safe for food storage, there are a few considerations to keep in mind. One potential issue is the prolonged storage of food in Mylar bags. Although Mylar can protect food from oxygen and moisture, it doesn't prevent the growth of anaerobic bacteria in low-acid foods such as meat and certain vegetables. Therefore, it’s crucial to follow proper canning and preservation methods to ensure food safety.

In addition, while Mylar bags protect food from environmental elements, they may not be completely impermeable over time. If you notice any signs of damage or deterioration, it’s best to transfer the food to a new bag.

Conclusion

In summary, Mylar bags are a safe and effective option for food storage, particularly for dried goods and non-perishable items. Their ability to provide a barrier against light, oxygen, and moisture makes them ideal for preserving food for long periods. However, it is vital to choose high-quality Mylar bags specifically designed for food use and to follow safe food preservation guidelines.

By taking these precautions, you can successfully extend the shelf life of your food while ensuring that it remains safe for consumption. As you explore options for food storage, consider the benefits and safety of Mylar bags as a reliable solution for your long-term food preservation needs.
