What is a mylar bag?

Mylar purple strain  bags are made from several layers of laminated food-grade plastic and aluminum. Flower will not react with aluminum because it is separated by a food-grade plastic lining. Mylar bags provide good light, moisture, and oxygen barrier to protect the herb inside the bag.

The manufacturing process begins with a film of molten polyethylene terephthalate (PET) being extruded onto a chill roll, which quenches it into the amorphous state. It is then biaxially oriented by drawing.

Mylar bags are opaque, made from metalized polyester. With Mylar bags, the air is removed by the addition of oxygen absorbers, also known as oxygen scavengers.

Using Mylar bags with oxygen absorbers removes up to 99.99% of oxygen. The best vacuum sealer machines only remove around 99.5% oxygen, making oxygen absorbers 50 times more effective. Mylar bags with oxygen absorbers will remove the oxygen, but not nitrogen or other gases, so the actually volume of gas in the bag will only reduce by approximately one fifth. Bacteria can only grow in aerobic (oxygen rich) environments, so the presence of nitrogen and other gases in the sealed bag will not allow bacteria to grow.

Our mylar bags are also much ‘tougher’ and more resistant to gas permeability than vacuum sealer bags, due to their metalized nature. Mylar bags can be considered to be like a flexible aluminum can, protecting the contents from not just gas permeability, but also light, heat, pests and damage due to impact and environmental factors.

The bags are available with various openings: plain zip-lock bags, child resistant zipper bags; most bags are and vac-seal compatible for use with vacuum sealing machines.

Protecting your buds from light exposure is important, and mylar bags do just that, thanks to their opaque design. Because these bags prevent light from getting through, they help your  buds maintain their color, odor, and taste.
