Generally, marijuana Mylar bags are built to provide a strong barrier against air, light, and humidity. These are the key factors that determine the freshness of your product and its shelf life. If the bag allows more light, air, or moisture inside, your products stay fresh for shorter periods. If the bag has a higher quality, your bag keeps your products fresh for more months. 


If you want your products to stay fresh for more days, you have to observe optimal storage conditions. When properly stored, Mylar bags can keep your products fresh for about 6 months and up to 1 year.

Even when stored in perfect conditions, a combination of factors could still affect its quality and degradation rate.
