Sustainable heat-sealable paper for sugar stick packaging

In the HORECA sector, margins are tight. Manufacturers use high-speed VFFS machines with ultra-narrow sealing seams to minimize raw material usage per stick.

• The Problem: While PE-laminates seal easily on these narrow zones, standard recyclable paper does not. It typically requires wider sealing jaws (and more material) to hold the bond.
• The Constraint: The client needed to switch to a recyclable material without modifying their efficient machine setup or increasing the stick size. Any solution that required wider seams or slower speeds was commercially unviable.

We engineered a High-Tack Dispersion Barrier Paper specifically designed for difficult sealing conditions. Standard papers often fail on ultra-narrow jaws, but our specialized dispersion coating activates instantly at lower temperatures. This creates a fiber-tearing bond even on minimal surface areas, bridging the gap between paper sustainability and plastic-like seal integrity.

Technical advantages:

• Precision adhesion: Our specialized coating bonds instantly on the machine’s original ultra-narrow sealing zones, creating a seal as robust as plastic without requiring wider jaws.
• Drop-in solution: The material runs on existing vertical (VFFS) lines with zero mechanical modifications.
• Agility: The solution supports variable batch sizes, allowing the client to produce private-label sustainable sugar sticks for smaller cafe chains efficiently.
