A major hurdle in the cultivation of mushrooms is the use of mylar bags. These magic mushroom bags also known as "shroom bags" are created from a unique, airtight plastic that is food grade and provides for the appropriate management of air and humidity levels while also shielding mushrooms from contamination. The mushrooms can be kept in this magic mushroom packaging, which come in a range of sizes and styles.
The substrate may then be maintained at a constant moisture and temperature level by placing these mushroom packaging bags in a warm, dark location. As mylar is not easily porous, putting the shrooms in bags helps keep bugs and other pollutants out. Mylar foil bags for mushrooms are a crucial component of the mushrooming process since they keep the mushrooms safe from contamination.
