What Can You Store in Mylar Bags?
Mylar bags are loved by many brands and are popular in different industries, including food, cannabis, chemicals, agriculture, and pharmaceuticals.
When it comes to storing food, a few options truly stand out and, on average, you can store these products for an extended period of time. But exactly how long does food last in mylar bags?
- Nuts, crisps, chips, chocolate, candy, dried eggs, crackers, and nut butter have a shelf life of less than 1 year because they are not ideal choices for long-term storage due to high moisture and oil content. Brown rice has higher oil content and shorter shelf life.
- Dehydrated fruits and veggies have a lot of moisture, so they have a shorter shelf life, but it’s still a few years rather than months. When it comes to nuts and seeds, you’ll get around two years due to the natural oil they produce.
- Herbs, cornmeal, powdered milk, baby milk/formula, and more have a shelf life of 3 to 5 years.
- Gluten, granola, whole herbs, millet, mung beans, quinoa, peanut butter powder, powdered milk (semi-skimmed), powdered egg, rye, unbleached flour, and wheat flakes can be stored for 5 to 10 years.
- Butter/margarine powder, cocoa powder, white flour, and whole wheat flour can be stored for 10 to 20 years.
- Instant coffee, skimmed powdered milk, tea, vegetables, legumes, freeze-fried fruit and vegetables, grains, potato flakes, and dried onions can be stored for around 20 to 30 years.

- Milk, meat, nuts, and legumes don’t stay fresh for too long, so best not to store them for extended periods.

Frequently Asked Questions
What is a Mylar Bag? A Mylar bag is a type of flexible plastic packaging made from a special polyester film, known as BoPET (Biaxially-oriented polyethylene terephthalate). These bags are widely used for storing food, supplements, pharmaceuticals, and more. Their durability and moisture resistance help to extend the shelf life of items.
How Do Mylar Bags Work? Mylar bags create a barrier against moisture, air, light, and oxygen. When sealed properly (often with oxygen absorbers), they lock in freshness, prevent contamination, and protect contents from the elements. Their airtight seal makes them ideal for long-term storage, keeping products fresh and preventing spoilage.
Are Mylar Bags Smell Proof? Yes! Mylar bags are smell-proof, which is one of their key benefits. The thick, multi-layer structure helps trap odors inside, making them a go-to choice for storing items like coffee, spices, or even personal goods that you don’t want to leave a lingering scent. No more unwanted smells sneaking out!
Are Mylar Bags Reusable? While Mylar bags are durable and can be used multiple times if sealed properly, they are generally not designed for indefinite reuse, especially if they’ve been punctured or damaged. However, if the bag has a ziplock feature and hasn’t been compromised, it can often be reused for storing similar items.
Are Mylar Bags Safe? Yes, Mylar bags are safe for food storage and are commonly used in packaging food and other products. The material is non-toxic and doesn’t leach harmful substances.
