Storing food has been a major concern for humans since birth. In the past when refrigerators and cooling places were not common, people used to store food items using salt. Those living in colder areas were lucky to have snow all around to preserve food for longer periods.

In today’s era, storing and preserving food is not an issue anymore. Technological advancements have blessed us with refrigerators to store food products without worrying about being rotten. 

However, some food items require air-tight containers and bags to preserve and protect them from exposure to air, moisture, and light. One of the most popular ones is the mylar bag, which you may have seen in the supermarket while shopping for groceries.

What is a Mylar Bag?

Mylar bag is a popular form of packaging used for storing food items. These bags are manufactured from polyethylene terephthalate (PET) film, which makes it durable, transparent, and flexible. Moreover, mylar bags are also puncture resistant, cost-effective, and non porous, which increases the life of food items due to less exposure to light and moisture. 

Some of the notable features and benefits of mylar bags include:

Gas Impermeable

Cost-effective Food Storage

Light Reflective

Puncture Resistant

Child Resistant

Durable and Sturdy

What differentiates mylar bags from ordinary plastic is the amount of air transfer, which is zero when it comes to mylar bags. Whereas, plastic may allow little air to pass in, which is not as effective as mylar bags for food storage. 

What are Mylar Bags Made of?


As discussed earlier, mylar bags are used for food packaging to make it preserve for a longer period. Generally, mylar bags are made from stretched polyethylene terephthalate (PET) also known as biaxially-oriented polyethylene terephthalate (BoPET). What differentiates PET from the rest of the storing materials is that it is more effective than any other material. 

What is a mylar bag used for?

Food storage is widely used both commercially and for home use. Some of the items are stored in refrigerators while others are preserved in mylar bags. The extraordinary properties of mylar bags make them ideal for packaging materials such as sturdiness, puncture resistance, and gas impermeability. 

Compared to other packaging materials, mylar bags can enhance shelf life. It prevents moisture and air from passing through, making it more effective for extending the shelf life and perseverance of food. 

Dry and low fat food items such as powdered milk, nuts, chips, lentils, whole spices, wheat, beans, vegetables, granola, salt, and sugar are preferably stored in mylar bags. However, food items should not be stored in mylar bags for more than 5 years. 

In addition, mylar bags are also used for giving gifts due to their transparent and shiny appearance. 

What is a mylar bag for food storage?

Mylar bags for food storage are made from food grade plastic and aluminum. Both of them are effective in preventing food items from exposure to moisture, pests, air, and light, thus increasing the shelf life. Normally, mylar bags can bear temperatures from 0℉ to 176℉. 

Are mylar bags toxic?

As discussed earlier, mylar bags are made from food grade material, which is safe for storing food. The bags are resistant to toxins, BPA, and phthalates. The material used to make mylar bags is less prone to exposure to gasses, preventing it from air and moisture. The food items can be stored for more than 25 years, but it is recommended not to store food for more than 5 years in mylar bags.
