Vacuum Packing 101

A Guide to Vacuum Packaging

Vacuum packing or vacuum packaging is a form of modified atmosphere packaging found around the world. Vacuum packing removes atmospheric oxygen from the primary package products are enclosed in. Oxygen is the primary source of product degradation. The removal of oxygen can often extensively help extend product life. Consumable and non-consumable products are protected by vacuum packing.

The basic form of vacuum packing removes oxygen from a vacuum bag and seals off the bag once a vacuum cycle is complete. There are a variety of new processes that can be involved when vacuum packaging, some are covered below.


The History of Vacuum Packing

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. After WW II plastics became more popular and commercialized, this opened the door for vacuum packaging applications.

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.

Difference between Shrink Wrapping and Vacuum Packing

Though often confused, shrink packaging and vacuum packing are very different. Both forms of packaging appear to remove air from product packaging but in very different ways.

Shrink Packaging

Shrink packaging, like vacuum packing, uses a sealing bar and film to package a variety of products. Products are enclosed in film, and heat is applied to the shrink film to form fit the film to the product. Air escapes the shrink wrapped package through tiny vent holes along the film surface. These vent holes prevent a shrink packaged product from being wholly sealed from exterior elements.

Vacuum Packing

Vacuum packing removes oxygen from the primary packaging using suction. Once oxygen is removed from the package, the package is completely sealed off from exterior elements. This modifies the atmosphere within the package to extend the life of packaged products.

Vacuum Bag Sizing

Unit of MeasurementVacuum Bag SizeNotes to Consider
1 Cup5'x7'The 5'x7' bags fit one cup of dried or liquid products still allowing room for a seal to be made.
1 Pint6'x10'6'x10' bags loosely fit 1 pint allowing room for small products such as dried fruits, nuts, baked goods and more.
1 Quart8'x10'The one quart 8'x10' bags are a perfect for vacuum packaging cut meats, cheeses curds, and other deli products.
1/2 Gallon8'x12'Two quarts is a half gallon, the 8'x12' bags fit two quarts with enough room for a vacuum nozzle and to make a seal.
Gallon12'x18'The 12'x18' vacuum bags may be slightly large for a gallon of products, but it allows room to hold and maneuver the bag during the vacuum and sealing process.

What is Modified Atmosphere Packaging (MAP)?

Modified atmosphere packaging is a form of packaging that acknowledges product degradation is attributed to the surrounding atmosphere. Modified atmosphere packaging involves the removal and introduction of specific elements to increase product lifespan.

A variety of atmospheric gases can be used depending on the product being packaged. Though the most common gases used in modified atmosphere packaging are oxygen, carbon dioxide, and nitrogen, other gases such as carbon monoxide, sulfur dioxide, ethanol, and argon can be used.

Many foods in grocery stores around the world use a modified atmosphere packaging to extend shelf life. The ability to modify the atmosphere within the package dramatically increases the shelf life of a product. See a list of everyday products that use modified atmosphere packaging below.

Poultry- Some of the first products to be commercially packaged using modified atmosphere packaging. Low oxygen content with high carbon dioxide content is often used to increase shelf life.

Fresh Fish- The freshness of fish can break down quickly due to a rapid breakdown of enzymes. Fish placed in low oxygen MAP still have a tendency to break down quickly. Researchers have found that different fish react better with the introduction of different gases. A mixture of carbon dioxide, oxygen, and nitrogen can be used to obtain the most extended shelf life in some products.

Baked Goods- Moisture loss and the growth of mold are often the most common factors of baked good spoilage. Many MAP for baked goods uses carbon dioxide and nitrogen to extend shelf life.

Prepared Foods- Pre-cooked foods continue to grow in popularity around the world. Most prepared foods are chilled and packaged with carbon dioxide or nitrogen with little or no oxygen content.

Fruits and Vegetables- Increased carbon dioxide levels help slow down the degradation of fruits and vegetables. The balance between the proper amounts of carbon dioxide and oxygen can vary depending on the produce being wrapped. The wrong balance of oxygen and carbon dioxide can cause fermentation and off-flavors.

Items Needed For Vacuum Packaging

Vacuum packaging bags

The first things need for most vacuum packaging operations is a vacuum sealer and bags. Other additional items that are commonly used depending on the needs are an external air compressor and an inert gas. The most common inert gas used is nitrogen. Nitrogen bottles can be found at most local welding supply stores. Below is a breakdown of the different types of vacuum bags and vacuum sealer often used in commercial vacuum packaging.

Vacuum Bags and Film

Vacuum bags are the exterior package to the products customers purchase. There are a variety of thicknesses, types, and Oxygen permeability bags available on the market. When choosing a vacuum bag, companies want to ensure they choose bags thick enough for the products being wrapped. The most common vacuum bag thickness used is a 3 mil thickness. The 3 mil vacuum bag thickness is thick enough to protect most products being packaged adequately. Below are some varieties of vacuum bags available.

Chamber Vacuum Packing- Chamber packaging uses a vacuum chamber with a heat seal closure to remove air from the vacuum bag and complete a full seal. Vacuum chambers are very popular in meat and cheese packaging.

Vacuum Skin Packaging- Vacuum skin packaging uses two rolls of film to remove air and seal the exterior package. A chamber compresses the film together to create a seal and remove air. A variety of meats, sausages, and cheeses are often packaged with skin packaging or thermoforming.

Packing Vacuum Seal Bags

Hot Fill Vacuum Packaging- The oldest form of commercialized vacuum packaging. Hot fill vacuum packaging uses plastic bags dipped into water in excess of 180 degrees Fahrenheit. The negative pressure from the water removes excess oxygen, and then the bag is fully sealed to close off the product from exterior elements. Hot fill is still a popular method of vacuum packaging hams, whole turkeys, and a variety of other products.
