vQm Modified Atmosphere Packaging (MAP) helps protect the original quality and extend the storage life of wheat during storage and transport. Oxygen is extracted from the packaging and replaced with carbon dioxide (CO₂) or nitrogen (N₂), creating a stable and protective atmosphere around the product.
Wheat is particularly sensitive to oxygen, moisture and insects. These factors can alter grain condition and colour, cause physical product damage and lower the overall commercial quality of the wheat.
Correct drying and product inspection remain essential, as MAP cannot restore wheat that is already too moist, mould-affected or otherwise damaged.
Applying Modified Atmosphere Packaging to semi-bulk wheat can help growers, processors, exporters and ingredient suppliers preserve product quality during storage and international transport.
By reducing oxygen exposure and limiting external oxygen ingress, vQm MAP helps slow oxidative deterioration and supports the preservation of wheat colour and overall grain condition during storage and transport.
High-barrier liners strongly limit moisture exchange with the external atmosphere, helping wheat maintain its required moisture level and reducing the risk of rehydration, condensation-related damage and mould growth.
Modified Atmosphere Packaging can be used to treat insects across all life stages in, using low-oxygen, CO₂-rich or N₂-rich atmospheres without conventional toxic fumigants. For applications specifically focused on insect treatment, please read our Non-chemical Insect Treatment page for requirements and further guidance.
By helping wheat maintain its quality for longer, MAP provides greater flexibility in deciding when products are stored, shipped, processed or sold based on demand, logistics and market conditions.
Designed for efficient vacuum and gas flushing of full big bags and wrapped pallets.
A reliable seal is essential for maintaining the modified atmosphere inside the packaging. The recommended sealer depends on the selected packaging option.
Designed to measure and verify MAP conditions. Measuring the and CO₂ concentrations supports quality assurance and confirms that the required MAP conditions have been achieved.
To transport semi-bulk wheat, we recommend the following packaging:
All packaging is designed with the vQm valve sealed inside (that enables efficient gas flushing through one secure connection point at amazing speed) Explore the vQm Two-Way Valve →
Its form-stable square design reduces bulging and helps maximise the use of available storage and container space.
If you prefer using palletised sacks, boxes or other existing cacao packaging, you can stack them on pallets and enclose the entire unit in a vQm Wrapping Liner or a Hood liner in case an automated palletizer is used. This protects whole shipments at once without altering your existing bagging process.
Protect wheat against oxidation, moisture fluctuations and insects while preserving its flavour, appearance and commercial value.
