What Is a Vacuum Sealer and How Does It Work?
A vacuum sealer removes air from a plastic bag or container and seals it shut, creating an airtight environment. This process extends the shelf life of food, prevents freezer burn, and helps maintain flavor and texture. The absence of air slows down the growth of bacteria and mold, making vacuum sealing an excellent choice for long-term storage.
Types of Vacuum Sealers
There are three main types of vacuum sealers, each with unique strengths and weaknesses:
- External Vacuum Sealers
- These are the most common and affordable options for home use.
- The bag’s open end is placed into the machine, which then sucks the air out and seals it.
- Suitable for occasional sealing and small batches of food.
- Chamber Vacuum Sealers
- Often used in professional settings, these sealers remove air by creating a vacuum inside the chamber itself.
- Ideal for sealing liquids or foods with high moisture content.
- Larger and more expensive but highly versatile.
- Handheld Vacuum Sealers
- Portable and lightweight, these devices are great for quick sealing jobs.
- Typically used with special zipper bags or containers.
- Less powerful than the other two types but convenient for casual use.

Key Features to Look for in a Vacuum Sealer
1. Sealing Strength and Speed
Sealing strength determines how tightly the machine removes air from the bag. Speed is important if you’ll be sealing multiple items. A sealer with adjustable sealing modes can be a bonus, allowing you to handle delicate items like bread without crushing them.
2. Compatibility with Bag Types
Not all vacuum sealers work with every type of bag. Some require proprietary bags, while others are compatible with generic options. Using generic bags can save money over time.
3. Ease of Use
Look for models with intuitive controls, such as one-touch operation or presets for specific tasks. Easy cleanup, especially for sealers that handle liquids, is another key factor.
4. Additional Features
- Pulse Mode: Lets you control the vacuum manually to prevent crushing.
- Accessory Port: Enables sealing of jars or marinating containers.
- Roll Storage and Cutter: Conveniently stores bag rolls and cuts them to size.

Pros and Cons of Vacuum Sealers

How to Use a Vacuum Sealer Effectively
- Choose the Right Bag: Use high-quality, compatible bags to ensure a proper seal.
- Prepare Food Properly: Pat dry moist foods to improve sealing. For liquids, freeze them first if using an external sealer.
- Avoid Overfilling: Leave enough space at the bag’s open end for the sealer to work properly.
- Store Correctly: Label sealed bags with dates and contents for better organization.
Maintenance Tips
Proper care can extend the life of your vacuum sealer. Here’s how to maintain it:
- Clean Regularly: Wipe down the sealing bar and vacuum chamber after each use.
- Check for Wear: Replace gaskets or sealing strips if they show signs of wear.
- Store Safely: Keep the machine in a dry, dust-free environment.
When to Upgrade Your Vacuum Sealer
If your current vacuum sealer struggles to maintain a strong seal, overheats during extended use, or fails to handle your storage needs, it might be time for an upgrade. Consider investing in a model with advanced features, like a chamber vacuum sealer, if your food storage needs have grown significantly.
Final Thoughts
Choosing the best vacuum sealer comes down to your specific needs and budget. For most home users, an external vacuum sealer offers a good balance of affordability and performance. If you frequently seal liquids or large quantities of food, a chamber model may be worth the investment. Meanwhile, a handheld vacuum sealer is perfect for occasional use and portability.
By considering the features, maintenance, and type of vacuum sealer that aligns with your lifestyle, you’ll find the perfect tool to keep your food fresh and flavorful for longer. Remember to assess your storage needs and choose a model that will serve you well for years to come.
