If you use a zipper pouch full of nuts or a sealed bag containing your pet’s food, then you surely experience mylar bags in your life. They are one of the most popular packaging for food, medicines, and dehydrated items. However, stop here: these bags are not only usable for food storage, but popular for storing documents, CD cases, and even auto car parts. This unlimited usage story goes all the way to how they work to make things last longer.

How Do They Work?

Let’s find the remarkable journey of mylar pouches that makes them popular among all.

Low OTR Properties

One of the most significant shortcomings in other packaging is the lack of anti-oxidation protection. Mylar films such as BoPET and thick foil layers offer a low oxygen transmission rate (OTR), boosting the shelf life of your products. This mechanism offers:

1. Oxidation barrier protection
2. Lock in the flavor and aroma of the food
3. Protects nutrient degradation
4. Extend the shelf life from years to decades for dry goods.

Stop Moisture Outside from the Pouch

The multilayers used in these boxes are not just to add structure but also offer complete moisture protection and a humidity control feature. With added oxygen absorbers, they create a suitable environment that protects the inner products from mold, oxidation, and bacteria.

All layers work together to make a perfect environment for storage.

• The foil layer blocks light and air penetration.
• The BoPET layer prevents humidity from seeping in.
• The outermost layer works as a puncture-resistant layer.

Ultra Violet Safe that Prevents Food Degradation

These pouches offer superior light and UV protection, the two common factors responsible for food degradation. UV rays work as the nutrient breaker when penetrating inside the packed food. Aluminum-foiled layers work as a barrier to block these rays that prevent food from losing its freshness. This feature makes these bags suitable for long-term food storage as they boost the shelf life efficiently.

​Smell-Proof & Tamper-Resistant

For cannabis storage, these bags provide reliable odor containment, keeping strong aromas sealed inside. They also support regulatory compliance with tamper-resistant and child-resistant design options, giving brands an added layer of security and consumers greater confidence in product safety.

Long-term Storage

These heat-sealed bags are perfect for long-term storage of food and other products due to its remarkable protection. The inner PE layers are sealable and protect the food from contamination. But, how long can food remain fresh?

When the layers are combined with an oxygen scavenger, they can enhance the shelf life of dried food from 10 to 25 years or more. With the addition of Vacuum sealing, moist food can be stored for a longer period in these pouches.

​Conclusion

Mylar pouches are truly magical packaging items for several products. They are not just an outer protection, but also protect packed ingredients with a complete mechanism. With its near zero OTR features and moisture resistance quality, these bags are making your products last longer than you expected.
