Discover how vacuum packaging works and why it is an effective preservation technique.

Vacuum packaging is a technique used to extend the shelf life of foods by removing air and preventing the growth of bacteria and microorganisms. This preservation process prevents oxidation and keeps food fresh and delicious for longer.

Vacuum packaging works by sealing food in special plastic bags and then removing all the air from the bag. This can be done using a vacuum packaging machine, which uses vacuum pumps to remove the air, or by using plastic bags that can be vacuum sealed manually.

Vacuum packaging is especially useful for preserving perishable foods such as meats, dairy products and vegetables, as it reduces the growth of bacteria and minimizes the risk of contamination. In addition to prolonging the shelf life of food, vacuum packaging also helps preserve its flavor, texture, and nutritional value.
If you're looking for an effective way to keep your food fresher for longer, learning about vacuum packaging is essential. Discover how this technique works and all its advantages in this informative article.

Introduction to vacuum packaging

Vacuum packaging is a food preservation method that has transformed the way we keep our food fresh. In this article, we invite you to explore the fascinating world of vacuum packaging, focusing on the relevance of industrial vacuum packaging equipment, such as those provided by the renowned company Frimaq. Learn how this process works and why it has become such an important tool in the culinary and food industries.

How does vacuum packaging work?

Vacuum packaging is a simple but effective technology that has become increasingly important in the food preservation sector. It involves placing food in specially designed plastic bags and removing all the air from the bag. This step is crucial, since oxygen is the main cause of food breakdown. To carry out this process, we use vacuum packaging equipment, such as the innovative solutions provided by Frimaq. These devices use high-performance vacuum pumps to remove air from the bags efficiently and safely.

Benefits of vacuum packaging

Frimaq vacuum packaging equipment has taken the benefits of this technique to a higher level. These devices, in addition to prolonging the shelf life of food, maintain the freshness, quality and safety of products in an industrial environment. Frimaq food preservation solutions are designed for optimal efficiency and precision, resulting in reduced waste and increased profitability.

There are several advantages to vacuum packaging, especially in terms of hygiene and quality, but one of the most essential is that it preserves the aromas and flavors of the food, since there is no oxidation or dehydration.

Although there are different types of industrial vacuum sealers, most of them follow the same procedure:

1. Preparation of the product and packaging, placing the food in a specific bag for this purpose.
2. Air removal, vacuum: This bag is placed in the vacuum chamber of the vacuum sealer machine, ensuring that the opening is correctly positioned for sealing. At this point, air is removed from the chamber, creating a vacuum.
3. Sealing: The final stage where the bag is heat sealed and then cooled for a few seconds to ensure the seal is complete.
4. Reintroduction of air: After sealing the packaging, outside air is reintroduced into the chamber to equalize the internal atmospheric pressure with the external pressure.

Because the internal pressure is less than atmospheric pressure, the packaging material sticks around the food. As the introduction of gases may be necessary for the preservation of certain products, this material must have a very low permeability to gases, including water vapor, a process known as modified atmosphere packaging. This is done immediately after vacuuming and shortly before final sealing.

Common uses of vacuum packaging

Vacuum packaging is essential in the food industry to preserve perishable products such as meat, dairy and vegetables. Frimaq vacuum packaging machines are versatile, allowing companies to guarantee the quality and freshness of their products at every stage of the supply chain.

The science behind vacuum packaging

Vacuum packaging technology is outstanding and important in the industry. By removing oxygen from the food environment, oxidation is prevented and freshness is preserved. Frimaq recognizes the importance of this technology and strives to create vacuum packaging solutions that meet the highest standards.

One of the most common technologies in food packaging is vacuum packaging. By removing air from inside a container and reducing oxygen, which is the main cause of food oxidation and spoilage, the shelf life of the food is extended and therefore its shelf life is increased. It is a highly practical and simple technique that, when done correctly, leaves less than 1% residual oxygen inside.

Vacuum packaging is a procedure that removes air from a container, leaving it empty, with the purpose of extending the expiration date of the food. Stops the activity of aerobic bacteria, which are organisms that require oxygen to survive, such as Salmonella, Escherichia coli, Campylobacter and others, by removing the air with vacuum pumps. When performed correctly, aspiration leaves less than 1% residual oxygen content within the container.

Vacuum packaging versus other preservation methods

In terms of effectiveness and quality, vacuum packaging is unsurpassed compared to other preservation methods. Frimaq vacuum packaging solutions outperform alternatives such as freezing or the use of chemical preservatives because they preserve the quality of food without affecting its flavor or nutritional content.

Vacuum packaging for different types of products

Frimaq vacuum packaging is suitable for the preservation of non-food products, such as medicines, electronic products and textiles, as well as food. Discover how our solutions help protect and preserve a wide variety of industrial products.

Packaging films as a determining factor
Initially, vacuum packaging was carried out with bags, but modern technology allows the use of much more sophisticated products, such as sheets (co-extruded, shrink-wrapped, embossed...), wraps or films (single-layer, composite or multi-layer, with treatments special…). Skin films, which adhere to food and function like a second skin, are one of the most innovative technologies.

The sheets used for vacuum packaging must have very specific physical properties that allow food preservation:

  1. Protection against external mechanical attacks, perforations, light, temperatures, stretching, among others.
  2. Gas impermeability.
  3. Excellent temperature welding properties.

Conclusion and final thoughts

Vacuum packaging is an essential technique in the food industry, and choosing the right vacuum packaging machines is critical to success. With Frimaq vacuum packaging solutions, companies can ensure the freshness and quality of their products, reduce waste and improve operational efficiency.
