Mylar Weed Bags

Mylar Weed Bags for Your Cannabis Product

Most of us are familiar with mylar in one way or another. We’ve all seen mylar balloons…those shiny silver orbs that shout Congratulations! or Happy Birthday! at supermarket checkout stations. Mylar is incredibly strong and has specific properties that make it an ideal material for the packaging of many products…dry goods like rice, beans, and other grains, freeze-dried products, coffee, and especially cannabis!

Mylar bags are less permeable to gasses than other materials, especially oxygen, which makes cannabis degrade quickly. That means your product can be stored in the perfect internal environment, keeping your cannabis product fresh with a longer shelf-life. You can shape mylar into almost any type of packaging. Customize it to add color to the packaging, print your original artwork and branding, or add special configurations to really make it reflect your product.

Mylar packaging for weed, hemp, and edibles will keep your cannabis products in top-shelf shape.

What is Mylar?

Mylar Weed Bags

Mylar is actually the brand name of a product that was created in the 1950’s by Dupont Teijin Films. It uses a special type of plastic called polyethylene terephthalate which is stretched to create a polyester film that can be shaped into bags and pouches. Mylar is much less permeable to gasses, especially oxygen, than other types of materials used in the packaging industry.
Pouches and bags made from Mylar are opaque, scent proof and airtight, all characteristics desired in the marijuana packaging industry. You can use Mylar to create everything from exit packaging, flower bags 1/8ths, 1/4oz, etc, or for edibles packaging along with vape outer packaging and reusable packaging so your customers can easily store their cannabis at home. Contact Us today and C4M will create unique packaging for your top-shelf cannabis product with the ultimate protection from light, oxygen, and humidity.

If you are going to use Mylar for your cannabis packaging you need a heat sealer

Mylar Bags and Heat Sealing

A heat sealer is used to fuse the opening of a mylar bag. Mylar is basically a metalized plastic, so when pressure and heat are applied to two pieces of mylar, they meld together, creating an airtight seal that is so strong customer will usually need a pair of scissors to open it.

This is why mylar is a popular option for tamper-evident packaging requirements. Once a heat-sealed package is opened, you can definitely tell that it’s been tampered with. Most states require cannabis packaging to be tamper evident, so a heat sealer is a must for finishing off the packaging of your weed flower, edibles or pre-rolls.

There are different types of heat sealers available for businesses to purchase. Impulse heat sealers are the most basic and work almost like a stapler. You place the open end of the package into the machine and pull the lever down where an electrical impulse heats up and seals the package. Impulse heat sealers are good for single packages, but most businesses are looking to do a much higher volume and should invest in a band sealer. These sealers are automated and do the same job as an impulse heat sealer but at much higher volume.

Packaging or MAP

Oxygen is very detrimental to cannabis. When cannabis oxidizes, the cannabinoid structure of the product changes. THC turns into CBN, thus reducing the potency and degrading the efficacy of the product. Using a MAP process involves pumping an inert gas (such as nitrogen) into the inside packaging before sealing it shut. The nitrogen gas displaces oxygen, thereby acting as a barrier and delaying the oxidation of the product contained inside.

The nitrogen simultaneously creates a barrier around the cannabis, assisting in preserving product shape and masking aroma. Equipment for MAP processing can be costly, especially for businesses who are just starting out. Choose flexible barrier packaging for your product leave the option open if you choose to explore MAP processing at a later date.
