LEM Products MaxVac Textured Mylar Bags Features The LEM Products MaxVac Textured Mylar Bags are constructed from a multi layer combination of polyethylene aluminum and PET at a thickness of 5.9 mil giving them the strength to resist punctures while blocking both oxygen and water penetration. The embedded foil layer excludes light entirely a critical factor in protecting the flavor and freshness of dry goods and freeze dried foods stored for extended periods. Textured sides help eliminate hidden air pockets during the vacuum sealing process improving the overall seal quality when using an external vacuum sealer with increased sealing time and temperature. LEM recommends its own MaxVac vacuum sealers for best results though these bags are compatible with most external vacuum sealing equipment on the market. Each bag measures 11 inches by 13 inches a size well suited to repacking bulk purchased grains coffee or dried beans into smaller more manageable portions which can also reduce overall food storage costs. A tear notch is built into each bag for easy opening once a package is ready to be used and the bags are FDA food grade and BPA free for safe food contact. These bags are safe for refrigerator and freezer storage and can handle temperatures up to 176 degrees Fahrenheit though they should never be boiled or microwaved. Sold in a 50 count box and intended for single use only LEM Products MaxVac Mylar Bags are a practical long term food storage solution available for sale at GrabAGun.
