How Mylar Bags Keep Food/Flower Fresh

When we think of long term storage for food or flower, several ideas come to mind, including: 

• Glass jars 
• Metal containers 
• Ziplock bags 
• Vacuum sealing

There’s one bag option that beats out all of the above choices:

• Mylar bags. 

While Mylar bags started as a way to store items such as dry food for extended periods, the marijuana industry leans heavily on the use of Mylar bags to help maintain product integrity. 

This article is meant to educate people on why Mylar is such a dependable material for storing things such as dry food and marijuana for long periods. 

Here’s why Mylar is your number one bag option for keeping your product fresh:

How Mylar Bags Keep Food Fresh

The main reason people love Mylar bags is their ability to sustain food or flower’s freshness for long periods. 

Mylar has been in production since its invention in the early 1950s by the DuPont Chemical Company. There is a perfect middle ground struck with Mylar bags as they are light and thin, yet durable and strong. 

People aren’t just using Mylar for storing items as the material is utilized for insulators, solar filters, and more. 

Now that we’ve talked a bit about Mylar’s background let’s cut to the chase with how it keeps your product fresh. 

Mylar Capabilities 

When oxygen is removed from a Mylar bag, the bag conforms to the product inside. This stage is essential as allowing little to no oxygen within a bag is critical for extending the freshness of your product. 

If you want to be sure there’s little to no oxygen in your Mylar bag, strongly consider using oxygen absorbers before sealing your Mylar bag. When you implement oxygen absorbers, mostly all levels of oxygen will be removed from the pack. 

If food items or products or flower are exposed to light, it can damage the integrity of the product. Mylar bags luckily contain an internal foil layer that helps reflect light and keep your product fresh. Vapor deposition is a process used when producing Mylar bags where metal is sprayed onto the material to provide increased levels of protection. 

Heat seals on Mylar bags are the cherry on top of a bag design that ensures long-term product protection. 

The cons of opting for vacuum-sealed bags include: 

• Increased chance of air leak
• Allows light which hurts a product’s freshness 
• Doesn’t remove as much oxygen 

Survival enthusiasts solidify the strong reputation that Mylar holds. Many survival kits feature Mylar pouches. 

It’s easy to write on Mylar bags using a sharpie, something that’s key for organizing products within your business. Be sure to let the sharpie dry before handling the package, as touching the sharpie writing too soon can result in a smudge on the mylar bag. 

Mylar Recap 

Before we go any further, let’s give a quick recap of the advantages of using Mylar bags.

Mylar bags are: 

• Non-porous for labeling
• Oxygen resistant 
• Flexible
• Durable
• Puncture-resistant 
• Contains a foil layer that reflects light 
• Inexpensive 
• Convenient to use 

Myths and Misconceptions Surround Mylar Bags 

There are some myths and misconceptions regarding Mylar bags due to their increased tendency to be utilized for different types of products. 

One misconception is that thicker Mylar bags are better. This is false since two mil, and seven mil Mylar bags have similar levels of oxygen protection with the aluminum layer keeping oxygen low. 

Thicker Mylar bags aren’t always able to handle higher amounts of weight, but mylar bags with a grid-like structure can hold more elevated amounts of weight than a bag with increased thickness. 

The durability of Mylar is occasionally understated. While little breaks in the foil can appear after filling and transporting a mylar bag, these small breaks won’t at all affect the product stored inside.
