What Is a Vacuum Sealer and How Does It Work?

A vacuum sealer is a device designed to remove air from a packaging bag before sealing it, creating an airtight environment to preserve food and other items. This process helps prevent spoilage and extends the shelf life of perishable goods by inhibiting the growth of bacteria, mold, and yeast.

According to the USDA, vacuum sealing can extend the storage life of food products significantly longer than traditional methods, making it a popular choice for both home users and commercial food processors.

Key aspects of vacuum sealers include their ability to create a tight seal around food items, which not only preserves freshness but also prevents freezer burn and dehydration.
