3. Setup (Initial Use)
Before first use, wash all bags thoroughly by hand with mild soap and warm water. Rinse completely and air dry. This ensures cleanliness and removes any manufacturing residues.
4. Operating Instructions (Usage)
- Filling: Open the bag by gently pulling the zipper seal apart. Place food items inside, ensuring not to overfill.
- Sealing: To seal, align the two sides of the zipper closure and press firmly across the entire length of the seal. For an airtight seal, press out as much air as possible before fully closing.
- Storage: These bags are suitable for storing a variety of foods, including fruits, vegetables, meats, cereals, and snacks. Their transparent design allows for easy identification of contents.
- Freezing: The bags are freezer-safe and designed to protect food from freezer burn, maintaining freshness and flavor.
- Marinating: The leak-proof seal makes these bags ideal for marinating meats and other foods.

5. Maintenance and Care
- Cleaning: Hand wash the bags using warm water and mild dish soap. A bottle brush can be used to clean corners and crevices.
- Drying: After washing, invert the bags or place them over a mug or cup to allow for complete air drying. Ensure bags are thoroughly dry before storing to prevent mold or mildew.
- Important: These bags are not recommended for dishwasher use, as the high heat can damage the double closure sealing technology.
- Microwave Use: The bags are microwaveable. However, ensure the zipper seal is open to allow steam to escape when heating.

6. Troubleshooting
- Difficulty Sealing: Ensure the zipper tracks are clean and free from food particles. Press firmly along the entire seal from one end to the other.
- Retaining Odors: Some strong-smelling foods may leave residual odors. To minimize this, wash bags immediately after use and air dry thoroughly. A baking soda solution or lemon juice rinse can help neutralize persistent odors.
- Bags Damaged During Sous Vide: These bags are designed for general food storage and freezing. They are not intended for high-temperature cooking methods such as sous vide, which can compromise the material integrity and seal.
