Vacuum sealing removes almost all of the air from a package before sealing. When combined with a high-barrier foil laminate mylar bag, this creates one of the most effective food preservation methods available: no oxygen, no moisture, no light, no spoilage.
Vacuum sealed mylar bags are used in food production, long-term storage, meal prep, and commercial preservation for products where maximum shelf life and freshness preservation are the priorities.
A vacuum sealer removes air from the bag before the seal is completed. The machine applies suction to the open end of the bag, drawing air out, then heat-seals the opening while maintaining the low-pressure environment inside.
The result is a bag that has been compressed against the product with very little residual air. Without oxygen, the biological and chemical processes that cause spoilage and degradation are dramatically slowed.
For vacuum sealing to work effectively, the bag must:
- Be made from a material that doesn't allow air to re-enter after sealing
- Have a quality heat seal that doesn't leak over time
- Be appropriate for the vacuum sealing process (some materials can crack or fail under the compression stress)
Foil laminate mylar bags meet all these requirements and are the preferred material for long-term vacuum storage.
Both methods remove oxygen from a food package, but they work differently and suit different applications:
Vacuum sealing physically removes air. It's better for products with irregular shapes, products that can be slightly compressed without damage, and applications where you have vacuum sealing equipment. It's immediate and doesn't require chemical absorbers.
Oxygen absorbers chemically absorb oxygen within a sealed bag. They work through a chemical reaction rather than physical removal. They're better for products that can't be compressed (crunchy snacks, chips, powders) and are preferred for long-term ambient storage.
Combined approach: Some commercial and home food storage operations use both: vacuum sealing reduces oxygen significantly, then an oxygen absorber removes the residual. This achieves near-zero oxygen levels and is used for ultra-long-term storage goals.
Meat and fish: Vacuum sealing extends the refrigerated shelf life of fresh meat and fish significantly by preventing the aerobic bacteria and mould growth that cause spoilage. For sous vide cooking, vacuum-sealed bags are essential.
Cheese: Vacuum-sealed cheese maintains quality and prevents mould growth far longer than standard wrapping.
Nuts and seeds: High fat content makes nuts prone to rancidity when exposed to oxygen. Vacuum sealing significantly extends shelf life.
Coffee: Some specialty roasters vacuum seal whole bean coffee to preserve freshness for longer periods.
Prepared meals: Meal prep services and sous vide restaurants use vacuum sealed bags for portioned meals.
Long-term food storage: Combined with mylar bags, vacuum sealing is a step in many long-term emergency food storage systems.
Fresh herbs: Vacuum sealed herbs in the fridge last significantly longer than conventionally stored fresh herbs.
Electronics and sensitive components: Vacuum sealing protects from humidity and oxidation in storage.
- Raw mushrooms: produce gases that cause bag failure
- Soft fresh bread: gets crushed; use for storage only, not presentation
- Some soft fruits: get crushed under vacuum pressure
- Raw garlic and onions: can produce gases and grow anaerobic bacteria in vacuum conditions
- Highly carbonated beverages
The ideal mylar bag for vacuum sealing:
- Textured or embossed inner surface: creates channels for air to be drawn out evenly. Smooth-interior bags can be difficult to vacuum properly because the surfaces can seal against each other before all air is removed.
- Appropriate wall thickness: 3.5 to 5 mil is standard for most applications. Thicker bags are more puncture-resistant; important for products with sharp edges or bones.
- Quality heat seal edge: The seal must maintain under vacuum conditions during and after sealing.
At TheCardBoardBoxes, vacuum-seal compatible mylar bags are available in a range of sizes and specifications. Custom printing is available for brands presenting vacuum-sealed products in retail or direct-to-consumer channels.
