How to identify the right Mylar Bags for your Cannabis business


Being a cannabis business owner, you are bound to be confused when choosing the right child-resistant packaging for your cannabis products. With the growing number of options available in the market, it is no easy task to shortlist the proper packaging format for your products. 

Among many other cannabis packaging options, mylar bags have shown immense promise and quickly gained popularity. They serve as the standard packaging solution for many businesses. If you, too, are interested in purchasing mylar bags for your cannabis business but aren't aware of its details, this blog is for you! 

What is Mylar?

DuPont owns the trademark 'Mylar.' Mylar is a PET FILM brand name. It is manufactured from the fibers of a compound called polyethylene terephthalate. PET is famous for its chemical and dimensional stability, barrier properties, insulative nature, reflectivity, and tensile strength.


The three layers of a Mylar Bag

A Mylar Bag is composed of three different parts. These three parts are the surface, middle, and lining layers. 

  1. Surface Layer

This layer is the printed part of the mylar bag. You can use this layer to print your logo, graphic, design, and label information.

  1. Middle Layer

The middle layer can also be called the 'strengthening layer' as it provides maximum protection to the bag's contents. It protects the contents from moisture, air, and light. It also restricts the smell from leaving the bag.

  1. Lining Layer

This layer is in direct contact with the contents of the bag. It is generally made of food-grade material to make it perfect for consumable products. 


Mylar Bags as Marijuana Packaging

Mylar bags are a popular packaging solution in the marijuana business. They offer an optimal packaging and storage mechanism as they are airtight, watertight, and puncture-resistant. Additionally, they can be heat sealed to keep the products fresh.

These bags are available in opaque, clear, and semi-opaque varieties, making them ideal for carrying marijuana around as well. They are tamper-evident and child-resistant. They have a zip-locking mechanism and a tear notch at the top, so you'll know if someone has attempted to access your packaging. 


Benefits of using Mylar Bags for cannabis packaging

Now that you know more about Mylar bags let us see why they are the best packaging option for your cannabis dispensary or head shop.  

  • Keeps cannabis fresh and maintains its potency

If cannabis is exposed to UV light and oxygen, it starts degrading faster. Mylar bags protect the cannabis product from UV rays and keep it fresh for an extended period.

Mylar is non-toxic and preserves the flavor and potency of your cannabis product. Some states require all dispensaries to package their cannabis goods in Mylar bags, making them necessary for dispensary owners.  


  • Suitable for Branding

Mylar bags are also great for branding. You can easily display your cannabis dispensary's logo or brand name on the bag itself so that customers can see it right away without opening the container and affecting the quality of your product. Mylar is hugely flexible and can be printed in many different ways, including using a silkscreen.


  • Flexible Sizing

Mylar bags are available in a wide range of sizes, making them easy to match your cannabis dispensary's needs. Mylar is also reusable. Mylar bags are ideal for getting your product out there while still protecting it from the elements that could affect its quality or shelf life. You can also custom order your preferred size right from pre-roll to 3.5 grams to an ounce. 


  • Durable for transportation and storage

Keep in mind that if you sell your product inside a transparent container, you may be required to wrap the entire thing in a mylar bag anyway due to marijuana laws. Mylar bags work great as primary as well as secondary packaging. Mylar is tough enough to store your products even in the most crowded stockroom. They can easily withstand bulk or personal transportation as well.


  • Smell Proof

Since you have been in the cannabis business, you know that not everyone approves of marijuana – even though it is safer than tobacco. Your customers will want a discreet packaging solution to throw such naysayers off. With mylar bags, they can safely store their favorite marijuana-related items without having to answer awkward questions from their housemates, friends, or neighbors. The bag's high vapor barrier prevents moisture, oxygen, and fragrance from entering or exiting the packaging. Smell proof bags allow your clients to keep their purchases private.

You will also need to consider the type of seal on the bag. Some Mylar bags come with a heat seal, while others are sealed using the ultrasonic method. Mylar bags that use heat sealing can be opened and resealed multiple times using an industrial-strength hot iron or heat gun (source). Mylar bags requiring ultrasonic sealing cannot be reclosed after opening.

The thickness of Mylar material is also an important consideration. Thicker the Mylar, more the protection against light and moisture. However, thicker Mylar bags are also more expensive than standard ones.
