Packaging companies offer mylar bags for cannabis and other cannabis-related products because Mylar is a great material to use. If you’re new to the world of cannabis storage, you may be wondering why mylar bags are such a popular choice. But first, here’s the scientific background on Mylar. It’s the name given to a polyester film trademarked by DuPont in the mid-1950s. Polyethylene terephthalate film (PET) is stretched to acquire a grid-like shape and reduced thickness. As biaxially oriented PET (boPET) or Mylar, the film goes through a high-temperature oven to become crystallized in this form, preventing it from shrinking back to its original condition. Due to its molecular orientation, Mylar has high strength, resistance to extreme temperatures and excellent transparency. Since the film’s surface is so smooth and thin, it can become sticky. This issue was solved by embedding microscopic inert inorganic particles like silicon dioxide in the film’s structure to make handling easier. So why are Mylar bags the best choice for cannabis?

Here are just a few of the benefits:

Mylar bags are airtight, which helps keep your buds fresh for longer periods of time.

They are also water resistant, which can be helpful if you live in a humid climate.

Mylar bags provide protection from pests and other bugs, which can ruin your buds over time.

Mylar doesn’t let in light.

When packaging companies like CannaZip create customized Mylar bags for clients, they offer sizes that make sense for the different products. If you’re interested in reusing them, Mylar bags are an excellent way to store cannabis for the long term. By keeping your buds in a sealed mylar bag, you can protect them from oxygen and light damage, which can cause them to lose potency and flavor.

When choosing a mylar bag for cannabis, be sure to get one that is food grade and heat-sealed. You’ll also want to make sure that the bag has a zipper or seal to keep the air out. 

To use a mylar bag for cannabis storage, simply place your buds in the bag and seal it shut. Place the bag in a dark, cool location and it will keep your buds fresh for months or even years. Finally, be sure to label the bag appropriately. This will help you keep track of what’s inside and make it easier to find later on.

Buying products in reusable mylar bags also helps the environment, because once you’ve consumed the initial product you can continue to use the bag for other purposes, as the quality material will withstand a lot of usage.
