As the focus on sustainability continues, many flexible packaging manufacturers and consumer packaged goods companies (CPGs) are looking to incorporate more sustainable options into their packaging. These options may include incorporating post-consumer recycled (PCR) content, using biodegradable or compostable materials, transitioning to a mono-material structure versus a multi-layer structure, and switching from a plastic structure to a paper structure. Incorporating these changes often requires a transition between flexible materials, which may result in operational challenges.
