Ever wondered how those tiny ketchup packets stay fresh and open so easily? In this video, we explore the engineering behind portion pack packaging with tear notches. You'll see how these single-serve sachets are designed for fast food, takeout, and catering applications, and learn about the multi-layer film technology that keeps contents fresh. We'll also demonstrate how the same packaging principles apply to larger spout pouches for honey, juices, and purees.
