Food packaging laminates

This invention describes a method for creating flexible food packaging materials. It involves feeding a first layer, applying a non-reactive hot melt adhesive using a slot nozzle positioned slightly above the surface, and then pressing a second layer onto the adhesive. The resulting material can then be sealed to form food packages.

Why it matters: Filed before today's heightened regulatory standards and consumer awareness regarding migratable contaminants in food packaging. The invention's focus on non-reactive, low-contaminant laminates aligns with current food safety priorities.
