Modified Atmosphere Packaging comes in all shapes and sizes. Big Bags are, unsurprisingly, the biggest one amongst them. We’ve picked apart our FIBCs to explain what elements a FIBC with Modified Atmosphere needs to keep your products fresh and safe for longer.
The Big Bag
First things first, the FIBCs. These are made out of 100% virgin polypropylene, a petroleum-based product, also known as a thermoplastic. One of the many factors that determine which bag to choose, has to do with static electricity. For this purpose, Big Bags can be divided into four general categories based on their material: Type A, B, C, or D. Which one you need, is based on the control of static electricity of the product you want to pack. We’ve dedicated a blog to finding the right FIBC for you here.
You can also choose a coated Bulk Bag. They have an additional polypropylene film, either inside or outside of the bag, to seal the small gaps in the poly weaves.
The liner
To protect the product and the Modified Atmosphere, it is key to have a liner that keeps everything out and in the bag. Liners can be made out of different materials. They protect against contamination, moisture, and oxygen.
We use all available barrier foils for our lined FIBCs: conductive, aluminium, anti-static, dissipative, metalized OPP, EVOH and PA liners. For a safe working environment, all our FIBCs can be designed and produced as a UN Bag or as a conductive Type B, Type C or Type D FIBC.
Sensor Spot for smart measuring
A key element of a successful Modified Atmosphere, is to keep monitoring the levels of gas in the packaging and the quality of the product. Since it is impossible to maintain the modified atmosphere when simply opening the package, we work with a smart solution that allows us to perform measurements in a safe and invasive way.
