The Flexivent: Block Bottom Bag with Ventilation System
To pack fine powder products such as milk, cocoa, and protein powders, flour, starch, and sugars, Gopack introduces the Flexivent blockbottom bag. This packaging features a special ventilation system that allows excess air to release after closing, without any loss of product. As a result, the packaging volume is optimized and product quality is preserved during transport and storage.
The Flexivent bag is compatible with standard filling machines and can be easily sealed or stitched after filling. Thanks to the design of the ventilation chamber, any remaining air exits the bag during palletizing, which can improve the efficiency of logistics processes.
The packaging is fully customizable to customer specifications and made from 100% polyethylene (PE), making it recyclable. This makes the bag a more sustainable option.
