Truth about the vacuum packaging you may want to know !

Though early experiments of modified atmosphere packaging have been traced back to the early 19th century, most accounts of vacuum packaging are not acknowledged until after World War II. In France before WW II, the air was removed from rubber latex bags, and the bags were sealed. This concept proved to increase the shelf life of frozen products.

The Cryovac vacuum packaging process created in the 50s to package whole turkeys was the first commercial use of vacuum packaging perishable items. Since the introduction of industrial vacuum packaging, many companies and individuals have contributed new methods, materials, and machines that have improved the quality of human life.

By the 70s, the idea of introducing an inert gas into vacuum packaging helped to increase the shelf life of perishable products dramatically. Since then, the advancements in vacuum packing efficiency and increased shelf life have made incredible advancements.

Now it’s seem you have a basic know of vacuum packaging, let’s see the types of vacuum bags packaging we commonly use in our life.

All vacuum packaged foods must be top quality, fresh and prepared in a sanitary method in order to reach optimum shelf life. In addition, shelf life can be affected by acidity, pH level, temperature and ingredients.

Some typical shelf lives of vacuum packaged refrigerated products, as compared to normal refrigeration, are:

The above shelf lives may vary and can be affected by product freshness, acidity, pH level, temperature, ingredients, sanitation and laminates used in pouch construction.

Previously we mentioned the application of vacuum bags packaging in our daily life, you may confuse about why there is everywhere using vacuum bags packaging? What are some special advantages of Vacuum Packaging? Thus, we list several FAQs about vacuum packaging, also the advantage introduction about using vacuum bags packaging as well.

Let’s see!

Q: Do Vacuum Packaged products still need to be refrigerated?

A: Yes. Some organisms are resistant to high carbon dioxide levels. Their growth is slowed at lower temperatures

Q: What are some special advantages of Vacuum Packaging?

A: Only a sampling of the advantages include:

1. Vacuum packaging reduces product shrinkage. There is no moisture loss or evaporation in sealed vacuum bag. Therefore, the weight you package will be the weight you sell.
2. Vacuum packaging reduces trim losses by eliminating oxidation and freezer burn.
3. Vacuum packaging can enhance product quality. Vacuum packaged meat held at 32° to 35°Fdoes not hinder “aging” or tenderising.
4. Vacuum packaging allows more efficient use of time. Food can be prepared in advance without loss of freshness, so slack times are more productive and busy times are more manageable.

Products such as cheese, continental small goods, fish, bacon, coffee and nuts, processed meats and many other food items may be bought in bulk at a lower price and then pre-packaged by either a central warehouse or in each supermarket or restaurant outlet.

2. Reduced Product Loss – Increased shelf life directly affects the reduction in product loss for companies inventorying products. The reduced product loss helps to increase bottom lines.

3. Sealed Barrier From External Elements – The most common vacuum bag thickness is a 3 mil thickness with some Vacuum Packaged Dried Fruit bags up to a 6-8 mil thickness. With the proper seal, vacuum packaging can protect products from dust, moisture, insects, and a variety of other external elements that may harm or damage products.

4. Seals in Flavors – Wet aging meats is a popular form of curing meat before preparing it. This often uses natural juices from the meat with spices and flavours vacuum sealed to lock in flavours during the curing process.

6. Improved Product Presentation – Most vacuum bags are crystal clear allowing products within the packaging to be displayed on shelves. Vacuum packaging is an affordable packaging solution the enables products to be shelf-ready Vacuum Packaged Dried Tomatoes with the application of a custom printed sticker.

7. Multiple Packaging Options  – Vacuum sealing materials come with multiple packaging options. Users can buy rolls of film or bags to seal products. Bags can be found with reclosable zippers, easy-open tear notches, foil-lined, channeled, and with a variety of other options to choose from.

8. Quick and Efficient Packaging – With the proper machines and materials, vacuum sealing can be a very efficient process enabling hundreds or thousands of products to be sealed per hour.
