We’ve been working with Al Aman and his team at Unified Flex for approximately 5 years. Unified Flex worked on all aspects of our needs to make our process better. They were willing to do what we needed to get done and delivered exactly what we wanted. Not only did Unified Flex provide us with the most economical options, they also provided an exceptional service level that we couldn’t have asked for any better. The best part was, that we got the best bang-for-our-buck. We know we could have spent many times more than what we did.

Our application was unique and challenging because it required equipment that could produce a special shaped pouch. Filling the pouches also produced challenges because of the viscosity of our product. In June 2016 Unified Flex provided us with a customized turnkey system and high-quality packaging film that fit our application perfectly. They also provided us with training and technical support to overcome each challenge that surfaced. We are impressed with the high-quality packaging film and the exceptional printing quality for our pouches that Unified Flex supply us. All-in-all a total solution that assists us in bringing a unique single serving size product to the market.
