This invention describes a flexible packaging material made by bonding two flexible layers together using a special hot-melt adhesive. The adhesive is designed to be free of harmful chemicals like migratable isocyanates and aromatic amines, preventing them from contaminating food. The patent specifically claims a method of packaging food by surrounding it with this laminate, forming it into a bag, and then sealing it.
Why it matters: Since 2007, regulatory scrutiny and consumer demand for food packaging free from chemical contaminants have significantly increased. This makes a laminate explicitly designed to avoid migratable isocyanates and aromatic amines more relevant today.
