GSF

Main requirements

  • High shelf lids: the barrier layer (EVOH) provides an effective oxygen barrier.
  • Good drawability & high puncture resistance: the bulk layers define melt properties (melt strength and thermoforming) and solid-state properties (tensile strength, puncture resistance, tear resistance, and optical clarity), making up 40-60% of the total structure.
  • Heat resistance & superior optics: The outer layer ensures mechanical protection and thermal stability during the packaging process .
  • Secure sealing to the tray: The sealant layer ensures strong adhesion between the multilayer top film and the bottom tray.

Recyclability

GSF’s formulation is designed for recyclability.

Advantages of GSF

  • Superior Product Presentation: Enhances the visual appeal of packaged products.
  • Reduced Material Consumption: Minimizes packaging waste.
  • Extended Shelf-Life: Helps reduce food waste by preserving freshness for longer periods.

Innovative Paper-Based Packaging

GSF also offers an advanced and sustainable packaging solution using a high-rigidity paperboard made from up to 90% renewable raw materials (virgin fiber, no recycled content). It replicates the appearance and feel of a natural product while delivering excellent barrier properties and seamless processing on existing FFS machines.

This solution meets the high environmental and quality standards of consumers, food manufacturers, and retailers while enhancing purchasing appeal. GSF is available in various thicknesses.

Applications

GSF is a high-barrier paper laminate ideal for use in the food industry.
