Food shelf life extension is a priority for many businesses. Finding the best way to extend the shelf life and maintain the quality of perishable products can be challenging. Consumers expect the best, and packaging often acts as a measure of product quality.

Gas flush vacuum sealing is becoming the preferred method of ensuring longevity, freshness and safety in food and medical products. The process has significant advantages and presents an efficient and effective alternative to traditional packaging methods.

What Are Gas Flush Vacuum Sealers?

Gas flush sealing is a modified atmosphere packaging that keeps perishable food products fresh by substituting oxygen with a nontoxic gas like nitrogen. Gas flush vacuum sealers flush food products with nitrogen gas. Then, vacuum seal them to prevent oxidation, which causes food to mold and decay.

Nitrogen doesn't react with perishable foods like oxygen and does not impact flavor and texture. Nitrogen molecules are larger and heavier than oxygen, making it easy to push oxygen out of containers and providing cushioning for food and other products during transportation and storage. Nitrogen flush sealing is a cost-effective method of increasing product longevity and preventing spoilage.

Plus, it's safe to work with, as nitrogen makes up about 78% of the air we breathe. Aside from food products, gas-flushing vacuum sealers are also used for packaging medical and chemical products, forming a protective barrier between products and potentially harmful contaminants, including dust, moisture and microbes.

The Advantages of Gas Flush Vacuum Sealing

When choosing a sealing method for your packaging, understanding the benefits is vital to ascertain whether it's the right choice for your operation. Some of the many advantages of gas flush sealing include:

Extended Shelf Life

Nitrogen allows you to create an ideal atmosphere for products, removing all traces of oxygen. Secondly, vacuum sealing creates durable packaging that protects your products from the elements and any external contaminants, increasing product longevity and quality and keeping perishables fresh for longer.

Extending your products' shelf life reduces product losses, which is excellent for your consumers and bottom line.

Elevated Food Safety

Packaging your products with gas flush systems eliminates the need for chemical preservatives, reducing the risk and making your products more appealing to consumers. Nitrogen is the most abundant gas in the atmosphere, and we breathe it every day, making it safe for use in preserving and packaging food products.

Enhanced Product Appearance

The gas flush process prevents products from coloring. Oxygen interacts with the natural pigments in many foods, particularly meat products, which can cause them to appear discolored. Nitrogen and other non-reactive gasses prevent this discoloration from happening. Their non-reactivity allows food products to retain a fresh appearance, making them more appealing to buyers.

Protected Product Integrity

You can flush products with extra nitrogen depending on your needs. This process provides extra cushioning for fragile products so they don't break and retain their freshness during transport, storage and packing. More robust products also benefit from this additional protection to maintain the product's structure.

This packaging method also seals in flavors, allowing consumers a better user experience.

Ease of Use

Gas flush systems are quick, efficient and user-friendly. You can automate the process and customize the settings for various products. Automating your equipment frees your team to focus on other critical tasks, reduces labor costs and increases output speed.
