“I am impressed by Lako’s continuous dedication to research and design for customer-specific applications. I presented Lako with the opportunity to help my company find a mechanical solution to an industry-wide problem — air retention in gusseted bags that are packed lying down in the case. They researched and designed four specific jaw serration patterns to test in the lab with different film structures, temperatures, sealing times and pressures to identify the optimal jaw set. Although this was not implemented due to a different business priority, it was a thorough feasibility study.”
