When it comes to preserving food for longer periods, vacuum sealing machines are a game-changer. With the right machine, you can keep your food fresh, reduce spoilage, and prevent waste. If you’re in the market for a vacuum sealer, this guide will walk you through everything you need to know to make an informed decision.
What is a Vacuum Sealing Machine?
A vacuum sealing machine is an appliance designed to remove air from a bag or container to extend the shelf life of food. It seals the bag securely, preventing exposure to oxygen, moisture, and contaminants that can spoil food.
How Does a Vacuum Sealing Machine Work?
The process involves placing food in a specially designed plastic bag or container. The vacuum sealer extracts the air, creating a vacuum, and then heat-seals the bag. This airtight seal helps maintain the freshness and integrity of the food.
Why Use a Vacuum Sealer?
Vacuum sealing extends the life of your food by up to 5 times. Whether you’re freezing meat, storing dry goods, or preparing food for sous-vide cooking, vacuum sealers offer a range of benefits.
Top Benefits of Vacuum Sealing
- Preservation: Keeps food fresh for longer by removing air.
- Space-saving: Vacuum-sealed bags take up less space.
- Reduced waste: Prolonged freshness means less food spoilage.
- Sous-vide cooking: Perfect for precision cooking.
Types of Vacuum Sealing Machines
There are several types of vacuum sealers available, each catering to different needs:
1. External Vacuum Sealers
These are the most common household vacuum sealers. They work by clamping the bag’s open end and removing air before sealing. Best for occasional use and sealing bags.
2. Chamber Vacuum Sealers
Chamber vacuum sealers are more robust and ideal for commercial use. They’re better at sealing liquids and are much faster but come at a higher price point.
3. Handheld Vacuum Sealers
These compact devices are designed for quick sealing and portable use. They are ideal for smaller sealing jobs and cost significantly less than external or chamber models.
Key Features to Consider When Choosing a Vacuum Sealer
1. Sealing Modes
Many vacuum sealers offer both wet and dry modes. If you plan to seal liquids or moist foods, choose a machine with a moisture mode to prevent leaks.
2. Bag Storage and Cutter
Some models come with built-in bag storage and a cutter, making it easier to create custom-sized bags without hassle.
3. Sealing Speed and Power
A powerful motor can create a vacuum and seal faster. Look for machines with adjustable settings to control the vacuum pressure.
4. Size and Portability
Consider the size of the machine if you have limited counter space. Larger, more powerful models tend to take up more room, while smaller, portable options might lack the features you need.
5. Vacuum Strength
This is often measured in inches of mercury (inHg). A higher vacuum strength means more air is extracted, which leads to longer preservation times.
6. Compatibility with Containers
Some vacuum sealers allow you to seal food in canisters, jars, and other containers, offering more flexibility in food preservation.

How to Use a Vacuum Sealing Machine
1. Preparing Your Food
Before sealing, make sure to clean and dry your food items. For moist foods, like meats or fruits, pat them dry to avoid excess liquid in the bag.
2. Inserting the Food
Place the food inside the bag, leaving enough space at the open end for the sealer to work effectively. For bulky items, use larger bags.
3. Sealing the Bag
Most machines will have an automatic sealing mode. Simply place the bag in the machine, close the lid, and press the start button.
4. Storing Sealed Food
Once sealed, store your food in the fridge or freezer. Remember to label the bags with the date for easy tracking.
Sous-Vide Cooking with Vacuum Sealed Bags
Sous-vide cooking has become increasingly popular in recent years. This method involves cooking vacuum-sealed food in a water bath at a precise temperature. The result is tender, perfectly cooked food every time.
Benefits of Sous-Vide Cooking:
- Precision: Controls cooking temperatures accurately.
- Consistency: Ensures food is evenly cooked.
- Enhanced flavor: Locks in natural flavors during cooking.
Common Vacuum Sealing Mistakes to Avoid
1. Sealing Wet Foods Incorrectly
If you’re sealing moist foods, use the wet food setting. Failing to do so can cause the liquid to interfere with the sealing process.
2. Overfilling Bags
Always leave enough space at the top of the bag to create a proper vacuum seal. Overfilling can prevent the machine from sealing properly.
3. Reusing Bags with Punctures
While you can reuse vacuum bags, avoid reusing ones with punctures or tears. These can compromise the seal and allow air inside.
4. Not Freezing Liquids First
For soups, sauces, or marinades, freeze the liquid before vacuum sealing to avoid messy spills.
FAQs
1. Can you use any bags with a vacuum sealer?
No, vacuum sealers require specific bags designed for this purpose. Regular plastic bags won’t work because they can’t withstand the vacuum process or provide an airtight seal.
2. How long does vacuum-sealed food last?
Depending on the type of food and storage conditions, vacuum-sealed food can last 2-3 times longer than non-sealed food. Frozen foods can last up to 2 years.
3. Is vacuum sealing food safe?
Yes, vacuum sealing is safe and helps preserve the freshness and nutritional content of food. However, it’s important to follow proper food handling and storage guidelines to prevent contamination.
4. Can you vacuum seal liquids?
Yes, but it’s recommended to freeze liquids first or use machines with a wet food mode to prevent liquid from interfering with the seal.
5. How often do I need to clean my vacuum sealer?
To ensure optimal performance, clean your vacuum sealer after every use, especially when sealing wet or moist foods.
6. Can vacuum-sealed bags be reused?
Yes, vacuum-sealed bags can be reused if they haven’t been punctured or contaminated with raw meat or other harmful substances.
7. Are vacuum-sealed bags microwavable?
Some vacuum-sealed bags are microwavable. Always check the manufacturer’s instructions to ensure the bag is safe for microwave use.
8. Can you use a vacuum sealer for non-food items?
Yes, vacuum sealers can also be used to protect important documents, electronics, and other valuables from moisture and dust.
