摘要：
A description is given of a method of producing packaging, the packaging surface being coated with a polyelectrolyte complex, and the polyelectrolyte complex being composed of at least one first polymer and at least one second polymer, the first polymer being an anionic polymer and the second polymer being a cationic polymer. The packaging is distinguished by good fat barrier properties.
