Bulk bag modified atmosphere packaging reduces spoilage and waste

Modified atmosphere packaging (MAP) technology from Masterpack Group USA helps food manufacturers meet increasingly tight regulatory requirements and rising expectations for product safety and quality in bulk packaging.

MAP is used for Flexible Intermediate Bulk Containers, commonly known as FIBC bulk bags, super sacks, and tote bins, where oxygen and moisture exposure can quickly degrade product integrity. Many food, dairy, pharmaceutical, and chemical materials have limited shelf lives or are highly sensitive to environmental conditions during storage and transportation.

Bulk bag MAP relies on specialized liners that create a low-oxygen environment inside the bag without the use of chemicals, toxic gases, or pesticides. Oxygen levels are reduced to below one percent through deep vacuum, followed by gas flushing with nitrogen or carbon dioxide to achieve the desired atmosphere. The process does not introduce any additives to the product itself.

By limiting oxygen, moisture, and pest exposure, MAP helps preserve product quality, reduce spoilage, and extend storage life. The technology also enables manufacturers to reduce or eliminate chemical fumigation practices and, in some cases, avoid the need for cold storage.

An additional benefit is the ability to conduct non-intrusive manual or automated sampling of the internal atmosphere, providing documented data for quality assurance and chain-of-custody tracking.
