Experience the United Bags Advantage for FIBC (Bulk Bags, Super Sacks) and small bags across a multitude of industries.

Modified Atmosphere Packaging, also known as MAP or MA, works by applying a vacuum to the 100% airtight high barrier liners within the external FIBC. The bags are then injected with nitrogen or carbon dioxide which results in residual oxygen levels inside of the liners being <1% and an inert atmosphere.

How does Modified Atmosphere Packaging work?

This method of packaging is a bio-based substitute for pest control since it kills insects. But there are more benefits as Modified Atmosphere also reduces mold formation, degradation, and oxidation of the product. Storing commodities with the MAP technology helps preserve optimal moisture content, aromas, and flavor. Therefore, MAP has the potential to prolong the products’ shelf-life significantly.

This method is the perfect solution for protection and storage for products such as food powders and products, nuts, dehydrated fruit, pharmaceutical powders (API), grain, coffee, rice, tea, chemical powders, pigments and many other products.

The Six Keys that Make Up Our Modified Atmosphere System

1. Liner Material

The liner in a FIBC depends on the product and circumstances during storage and transport. The liner is built with up to nine different layers of various materials, to create a barrier against moisture and keep ultra-low oxygen levels and the flavor intact. The liners are produced to very stringent quality conditions and up to ISO standards.

We use a wide range of barrier foils for moisture levels, oxygen and flavor for our liners such as conductive, aluminum, anti-static, dissipative, metalized OPP, EVOH and PA liners.

2. MA Powerqube & Powertube Liners

A FIBC with a form stabilized liner system inside ensures a square and optimal shape after filling, during storage and transport. The pre-shaped liner is completely welded in the top and bottom and if required in the side seams.

  • 15% on transport volumes can be saved with form stable FIBC Liners.
  • 15-20% less material used for the production of a liner
  • Modular produced
  • Unique controlled sealing technique
  • High load ability
  • ISO production facility

3. MA Powerqube & MA Powertube Liners

The valve is attached to the liner of the FIBC and gives a secure airtight connection between the environment inside the bag and the Vacuum and Gas Injection Machine. Each valve is equipped with a filter, which ensures that products stay in the liner and gasses can move openly in and out of the liner.

A reliable valve is the key to a successful preservation process! The benefits are:

  • Fool-proof connection
  • Fast processing times
  • Single or multiple flushes
  • Lower energy needed

4. Automatic Spout Sealer

A machine that seals the filling spout of a FIBC so that the product content is secured. Depending on the size and position of the FIBC, the machine can be adjusted to its correct height and width of the filling spout. After positioning the filling spout into the sealing machine, the sealing process is fully automatic.

  • Reliable and safe way of sealing
  • Constant quality and performance
  • Mobile moveable machine
  • Small footprint and setup

5. Vacuum & Gas Injection Machine

Modified Atmosphere is used as a way of natural fumigation, using ultra-low oxygen levels (ULO) in combination with Nitrogen or Carbon Dioxide to protect products from infestation by insects and extending the shelf life of your products.

  • Vacuum & gas flushing including pressure control & leak test
  • Short process times
  • Completely customizable process
  • Highest class approved machine

6. Modified Atmosphere Control

There are two different ways to measure and control the Oxygen level inside the bags.

  • The traditional and very reliable way to measure oxygen and gas levels is the evasive method which uses a needle tool that pierces into the sealed liner bag.
  • The new way is a totally non-invasive technique called Sensor Spot Technology that does not require piercing a needle into the liner bag.
