Zero-Heat Pattern Cold-Seal Cohesive Flow-Wrap Rollstock Film (Chocolate, Coated Protein Bars & Ice Cream)
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.
"Unblocking rollstock on the pallet and dead-cold-seal after 4 months of storage are the two biggest headaches for bar co-packers. We pair a polyamide release lacquer over reverse-trapped inks with allergen-free synthetic cold-seal patterned strictly onto the fin and cross-seal zones—guaranteeing smooth unwind and 3.8–5.5 N/15mm peel for 9 months."
