Mylar bags vs. glass jars for cannabis storage – an Amplified Farms case study

Amplified Farms has recently made the switch from glass jars to mylar bags for their indoor cannabis flower products. Having tried their products over the last year – I felt it would be a good time to address the pros and cons of the two most popular forms of cannabis storage that we see at dispensaries, highlight a trend, and provide a few tips.

Cannabis Storage in Glass Jars Pros and Cons


  • Nugs don’t get squished except by poor extraction
  • Glass is more insulating than Mylar and sans sun will be able to survive short temperature variations better



  • Clear glass lets the sun’s UV rays touch the flower
  • Clear glass let’s the sun heat up the flower more than in a mylar bag

Cannabis Storage in Mylar Bags Pros and Cons


  • Mylar has more surface area on the packaging for branding
  • Mylar bags are less weight and take up less space


  • Nugs in mylar bags get squished by the end user unless special care is given
  • Mylar bags are nowhere near as reusable as glass jars are theoretically



I’m not going to come out and say that one is intrinsically better than the other. No decision happens in a vacuum and one thing that everyone can likely agree on is that mylar bags are better than sandwich bags.

The benefits from stuff like less UV exposure or better resistance to the elements become less and less important the quicker you plan on consuming your cannabis product. Realistically, all of these items apply for processed cannabis products, too. I’m sure there are still places you can find shatter in parchment paper in mylar bags but by and large glass has won out there.

For storage on the shelf or in the back at dispensaries where the environment is controlled, and the entire logistical supply chain up to that point, I can see the benefits of using mylar bags. You can have more for less cost and that adds up in the long run.

Given the market conditions, if cannabis brands can keep their prices reasonable by cutting costs on the packaging without damaging the quality of the flower when it is sold, that is a win-win scenario for the grower and the buyer.

Nug looking good on Day 1.

The onus is now even more so on the buyer to properly store their cannabis for the duration they plan to hold onto it. Don’t put it in your back pocket, and definitely don’t just toss it into your backpack. In fact, if you want to store it for longer, you might consider taking your bud out of the mylar bag and putting it into one of the many glass jars you likely already have.
