Latest Patents

Na Wei holds a patent for the "Preparation method of high-barrier antibacterial flame-retardant food packaging film." This invention provides a solution to the limitations of existing food packaging films, which are often non-degradable and flammable. The preparation method involves a blending reaction of chitosan quaternary ammonium salt and phytic acid to create a polyelectrolyte complex. This complex is then incorporated into a polyvinyl alcohol solution, which is heated to form a film. The resulting food packaging film exhibits impressive properties, including water vapor permeability ranging from 1.82-2.58×10⁻¹⁰ g·s·m·Pa and oxygen permeability between 1.63-12.31 cm·mm·Pa·day. Additionally, it has a limiting oxygen index (LOI) value of 28.10%-33.33%. Notably, the film demonstrates instant self-extinguishing behavior upon ignition, making it a safer option for food packaging.
