Seal in the flavor, seal in the freshness - our sous vide bags offer a reliable and convenient way to prepare your meals to perfection, every time.
HohuiFlex offers premium-quality sous vide bags that are safe, reliable, and designed for precision cooking. As a leading Chinese manufacturer of sous vide bags, we provide a range of sizes to cater to the needs of professional chefs and home cook.
Sous vide bags with a valve are designed to allow for the removal of air from the bag before cooking, creating a vacuum-sealed environment that helps to preserve the texture, flavor, and nutrients of the food. The valve can be opened to remove the air using a vacuum sealer or a hand pump, and then sealed shut to create an airtight seal. These bags are typically made from food-grade materials such as BPA-free plastic or silicone, and are temperature-resistant, puncture-resistant, and available in a range of sizes and shapes to accommodate different types and sizes of food. Overall, sous vide bags with a valve are a convenient and effective option for achieving precise and consistent results when cooking with the sous vide method.

How to use sous vide bags?
Here are the general steps for using sous vide bags:
Choose a high-quality, food-grade sous vide bag. Ensure that the bag is free from any holes or tears that could allow water to leak in.
Prepare the food you want to cook. Clean and season the food as desired, and place it into the sous vide bag. Ensure that the food is evenly distributed and not overcrowded.
Remove the air from the bag. You can do this by using a vacuum sealer or manually by placing the bag in a bowl of water and pressing down to push out the air.
Seal the bag. Once the air is removed, seal the bag using a vacuum sealer or by using the zip-lock feature on the bag.
Cook the food. Place the sealed bag in a water bath that has been preheated to the desired temperature for cooking the food. Allow the food to cook for the recommended time based on the food type and thickness.
Remove the food from the bag. Once the cooking time is up, remove the bag from the water bath and carefully open it to remove the food. Be careful as the food may be hot.
Serve or store the food. Serve the food immediately or store it in the refrigerator or freezer for later use.
