What are Vacuum Pouches?

Vacuum pouches are specially designed plastic bags used with vacuum packaging machines to remove air from around a product before heat sealing the pouch to create an airtight package. They are commonly used to protect products from moisture, contamination and oxidation, helping to preserve freshness and extend shelf life. They are also commonly referred to as Cryovac Bags.

Vacuum pouches are typically manufactured from multiple layers of plastic, such as polyethylene (PE) and nylon (PA), providing strength, puncture resistance and an effective barrier against oxygen and moisture.

Types of Vacuum Pouches

  • Smooth Vacuum Pouches: Designed for use with industrial chamber vacuum packaging machines, commonly used in commercial food processing.
  • Embossed Vacuum Pouches: Feature a textured or channelled surface that allows air to be extracted when used with a domestic external suction vacuum sealer.
  • High Barrier Vacuum Pouches: Provide increased protection against oxygen and moisture, making them suitable for products requiring extended shelf life.
  • Boilable and Sous Vide Vacuum Pouches: Specially manufactured to withstand controlled cooking temperatures when used in boiling water or sous vide applications.

Benefits of Vacuum Pouches

  • Extended Shelf Life: Reduces exposure to oxygen, helping slow oxidation and certain types of food spoilage.
  • Product Protection: Provides a protective barrier against moisture, dust and external contamination.
  • Reduced Storage Space: Removes excess air to create compact packages for easier storage and transportation.
  • Product Visibility: Clear vacuum pouches allow the contents to be easily identified without opening the packaging.
  • Versatility: Suitable for packaging meat, poultry, seafood, cheese, prepared meals and various non-food products.

Common Applications

Vacuum pouches are widely used by butcher shops, supermarkets, restaurants, food manufacturers and commercial food processing facilities. They are also used for packaging industrial components and other products requiring protection during storage or transport.

Important: Vacuum pouches must be compatible with the vacuum packaging machine being used. Smooth pouches generally suit industrial chamber vacuum sealers, while embossed pouches are typically required for external suction on domestic vacuum sealers. Vacuum packaging does not eliminate the need for appropriate food refrigeration or safe handling.
