## Executive Engineering Summary

FlexPouchMFG™ manufactures precision register-applied pattern cold-seal cohesive rollstock films engineered for heat-sensitive chocolate bars, yogurt/chocolate-enrobed protein bars, wafer biscuits, probiotic snacks, and ice cream novelties. Sealing instantly by pressure alone (0.15–0.30 MPa at ambient 20°C) with zero heated jaws, our synthetic natural-rubber-free cohesive formulations eliminate chocolate bloom/melting while achieving 400–800 packs/min on horizontal flow-wrappers.
