The vacuum pack is a versatile pack style that people use for food preservation, storage, and protection against moisture and oxidation. It involves creating an airtight seal to extend the shelf life of various items. These items include fresh meat, processed meat, seafood, cheese, and dry foods like cereals and nuts.

Purpose and Objectives

The primary objective of this packing is to enhance space-saving capabilities while ensuring moisture protection and odour protection. Chefs and home cooks widely use this technique in sous vide cooking, marinating, freezing, and storing seasonal clothing. Additionally, vacuum packing plays a crucial role in industrial packaging, emergency preparedness, and travel essentials. It provides efficient storage solutions for items like camping gear and first aid supplies.

Machines suitable for Vacuum Pack

Vacuum Sealing for Freshness

Vacuum sealing is essential for extending the shelf life of fresh meat, processed meat, seafood, and cheese storage. By creating an airtight seal, vacuum packing prevents oxidation and moisture infiltration, crucial for maintaining the quality of perishable items.

Fresh Meat Preservation:

  • Vacuum packing fresh meat can extend its refrigerated shelf life by 3-5 times and prevents freezer burn, maintaining quality for months while containing odors.

Processed Meat Storage:

  • Deli meats and sausages retain flavor and texture, preventing drying out and cross-contamination.

Seafood Protection:

  • Vacuum packing locks in moisture for fresh fish and shellfish, preventing freezer burn and maintaining texture.

Cheese Storage Solutions:

  • Hard cheeses resist mold growth, while soft cheeses benefit from modified atmosphere packaging. Shredded cheese stays fresh and free-flowing.
