Bag-in-box packaging

We invented bag-in-box packaging over 70 years ago and combine decades of experience with deep industry understanding to bring exceptional value to our customers, delivering their products to market in exactly the way they were intended, whether they need retail, foodservice, bulk, or industrial bag-in-box.

The clever choice for efficient performance

Reduction is key to how we approach sustainability. Our bag-in-box packaging has a higher product-to-package ratio, which means more product can be packed with less material.


Reduction applies to more than just the packaging material used - we strive to help you reduce product waste as well. Because bag-in-box collapses as your product is dispensed, you can see over 99% product evacuation in most cases, regardless of product viscosity. The positive flow of our fitment and connector systems keep oxygen from entering the package, allowing for an extended open shelf life and giving your consumers ample time to use every last drop. 


Flexibility in package volume gives you valuable access to multiple sales channels, from retail to foodservice to industrial processing. Bag-in-box is designed to fit any container size or shape, giving your brand the opportunity to truly stand out from the competition. And, with our state-of-the-art bag-in-box filling lines, you can flexibly fill many volumes with a variety of fitments on the same filling machine.
