Liquipure® ultra


Award-winning Liquipure® ultra flexible packaging for bag-in-box uses advanced resin technology that is ultra-strong to provide reliable product protection, and yet sustainably simple, as we call it, to meet recyclability guidelines.

Revolutionary recycle-ready solution offering medium to high barrier protection

Traditional medium and high barrier bag-in-box packaging is comprised of laminated films using nylon or metallized polyester for strength and polyethylene for sealing, but the mixed-material designs pose challenges to recycling. By utilizing the latest revolutionary polyethylene technology, our Liquipure ultra design eliminates the need for nylon, while still achieving outstanding performance and durability to protect beverages and other liquid products. Not only does this new mono-material structure eliminate energy-intensive materials and processes, it is also compatible with existing polyethylene recycling streams so that you can achieve the sustainable performance your business needs and your consumers expect.

What is more, Liquipure ultra achieves equivalent evacuation standards without the need for an evacuation device, which further reduces plastic consumption while ensuring that products are not wasted. Another value chain benefit is the improvement in filling speed—Liquipure ultra has the capability to increase throughput on filling machines by 10%, improving efficiency and reducing downtime for customers.
