Bag-in-box films and laminates

Our knowledgeable engineers work to develop unique, sustainable, and durable film and laminate solutions for bag-in-box packaging. We strive to delight demanding end users through innovative technology and consistent delivery of reliable barrier films.

Designed for protection

We extrude, laminate, slit, and deliver barrier films and laminates designed to meet your product specifications and protect it throughout its entire life. Our wide range of solutions includes everything from one- to nine-layer films, as well as recycle-ready structures. Our films and laminates are:

  • Engineered with a focus on optimized functionality and fit for best-in-class seal quality 
  • Made to protect your product and withstand the rigors of difficult supply chains
  • Manufactured reliably with our vertically-integrated global footprint, ensuring supply contingencies

Our approach to bag-in-box films and laminates

Recycle-ready films and laminates

We focus on design for recycling. Producing recycle-ready film structures enable the finished packaging to be more-easily recycled and thus, have value after their initial lifespan.

Fit-for-purpose

The world can be unpredictable - that’s why it’s important that your packaging isn’t! We engineer our films and laminates to protect and deliver your products just as you intend, no matter what the supply chain throws your way.

Eco-conscious

Bag-in-box film - and the packaging it helps create - typically creates less greenhouse gas emissions than rigid containers. Because bag-in-box films and laminates provide a lightweight film structure, the package boasts an optimized product-to-package ratio, meaning you can pack more product with less material.
