Why Are Mylar Bags Ideal for Dehydrated Food Storage?

Mylar bags are considered superior packaging solutions in comparison to other packaging solutions. These bags are secure for direct food contact. They help fight against dehydrated food’s three major threats, that includes:

• Oxygen: Residual trapped oxygen causes permanent oxidation and spoilage of dried food. It accelerates chemical food deterioration, producing rancid, volatile odors.

• Light: Light forces dehydrated food to lose its nutritional value quickly. It highly impacts the taste of your food products. 

• Moisture: Even minor moisture exposure to surrounding dampness creates stubborn, unsightly mold growth.

This is why heavy duty Mylar bags for long-term food storage are considered a truly excellent solution. They keep delicate products secure from harmful contamination and product discoloration while maintaining original flavor for an extended time.

The thin metalized layer of tough Mylar bags offers exceptional barrier properties and keeps sensitive items safe for daily consumption.

Which Factors Affect the Shelf Life of Dehydrated Food?

The shelf life of dehydrated food stored in Mylar bags depends heavily on: 

Product Type

Different product types have different fats, residual moisture, and chemical composition, which determine the shelf life of dehydrated food stored in Mylar bags.

Packaging Quality

Solid packaging quality also boosts daily product safety from harsh environmental factors. Choosing reliable, high barrier packaging is the ideal way to block unwanted moisture and excess oxygen.

Storage Environment

The storage environment, such as cool, dry, and dark spaces, keeps products safe for many years. While, hot spaces can degrade food’s quality. 

The Role of Oxygen Absorbers in Extending Shelf Life

Powerful oxygen absorbers protect your delicate fresh food. These tiny packets keep sensitive goods safe and tasty for a long time. They fight harmful decay and preserve natural quality.

Inside each small pouch, active iron powder joins simple catalytic salt. This clever mix rapidly pulls trapped air away from your stored items. It grabs unwanted oxygen and slashes leftover air levels down to a tiny 0.01%. Your sealed food stays completely dry, crisp, and safe.

This helps prevent impulsive food spoilage, unhealthy mold growth, and keeps insects away.

It is particularly noteworthy to pick the accurate size (cc rating) based on the bag size. We’ve  added a mylar bag oxygen absorber chart of recommended sizes based on your Mylar bag size:

How to Suitably Store Dehydrated Food in Mylar Bags

The proper storage of dehydrated food in mylar bags plays a key role in extending their shelf life. But how you do it can instantly impact how long your products stay refreshed. Here’s how proper mylar bag food storage is accomplished:

• It is necessary to confirm that your food items are fully dehydrated with no moisture left. Moisture or a tacky texture of your food items can cause spoilage. 

• Choose the right bag size depending on your product's needs. 

• Then fill the bag and leave 2 to 3 inches headspace for a neat heat seal. 

• Add the accurate oxygen absorbers inside the bag. 

• Label the mylar bag with the product information, packing date, and estimated expiry date.

• Press out all the excessive air before heat sealing the bag. It helps build a strong barrier against exterior factors. 

• Store the bags in a dark and temperature controlled space to maximize the product’s shelf life. 

This is how Mylar bags are closed for a more extended shelf life. 

How Storage Conditions Affect the Shelf Life

The ultimate shelf life of premium dehydrated food stored in protective Mylar bags is heavily impacted by external storage conditions. 

The following are the crucial aspects that affect the overall shelf life:

• Temperature: The ideal temperature range for safe, long term storage is a cool, consistent 50 to 70°F. Excessive temperatures above this specified range cause rapid nutrient loss and significantly reduce expected shelf life.

• Light Exposure: Mylar bags are developed to block light inherently. But it is best to store Mylar bags in dark places. Exposure to UV light can spoil the quality quickly. 

• Humidity: High moisture can easily trigger mold and bacteria. 

Mylar bags are an ideal solution for retailers, resellers, or survival gear suppliers. They are prepared to meet the actual functional needs of your products.
