- Reusable bags: Great choice for everyday food preservation, reducing plastic waste.
How Vacuum Sealer Bags Work
Basic principles
- Vacuum Sealer: Vacuum sealer removes the air inside the bag, minimizing oxygen and slowing the spoilage of food.
- Sealing: After the air is sucked out, the bag mouth will be sealed, preventing outside air from entering.
Vacuum Process
- Prepare the Bag: Choose a bag suitable for the size and type of food to be stored.
- Placing the Food: Place the food in the bag, making sure to leave enough space at the top of the bag for sealing.
- Vacuum and Seal: Use a vacuum to remove air and seal the bag.
Benefits of Vacuum Sealer Bags
Effective Food Preservation
- Extends Storage Time: Food stored in vacuum bags can stay fresh many times longer than conventional storage.
- Preserves Flavor and Quality: Limits oxidation and bacterial growth, preserving food flavor and quality.
Economical and Convenient
- Reduce Waste: Reduce the amount of food that goes bad and is thrown away.
- Easy Storage: Vacuum bags help save storage space in the refrigerator or freezer.
Instructions for Use and Storage
Note when using
- Read Instructions Carefully: Each type of bag may have specific instructions for use, especially specialized bags.
- Choose the Right Bag: Depending on the type of food and storage purpose, choose the right bag.
