Quick Answer
Sealing Mylar bags with oxygen absorbers involves using a combination of a heat sealer, a Mylar bag, and oxygen-absorbing materials such as silica gel or calcium chloride. The process requires attention to detail to ensure a tight seal and effective moisture control.
Sealing Mylar Bags for Grain Storage
To seal a Mylar bag with an oxygen absorber, start by placing the absorber in the bag, followed by the grain. Use a heat sealer to seal the bag, ensuring a consistent pressure of 30-40 pounds per square inch (PSI) for 5-7 seconds. This helps to prevent air pockets and maintain a tight seal.
Tips for Effective Sealing
When sealing Mylar bags, it’s essential to use a high-quality heat sealer that is specifically designed for this purpose. Avoid using a household iron or other heat sources, as they may not provide the necessary heat and pressure to create a tight seal. Additionally, make sure to seal the bag quickly, as the oxygen absorber will start to work as soon as it is exposed to air.
Recommended Materials and Techniques
For long-term grain storage, it’s recommended to use a Mylar bag with a minimum thickness of 4 mils and a width of 8-10 inches. Use a heat sealer with a temperature range of 250-300°F (120-150°C) and a pressure of 30-40 PSI. Silica gel or calcium chloride oxygen absorbers are effective options for maintaining a low oxygen environment and preventing spoilage.
