Latest Patents

Yuping Ning holds a patent for a "Preparation method of high-barrier antibacterial flame-retardant food packaging film." This invention addresses the problems associated with existing food packaging films, which are often non-degradable, have poor preservation effects, and are 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 added to a polyvinyl alcohol solution, which is heated to form a film-forming solution. The solution is poured into a mold, leveled, and dried to produce the high-barrier antibacterial flame-retardant food packaging film. This innovative film exhibits water vapor permeability ranging from 1.82-2.58×10⁻¹⁰ g·s·m·Pa, oxygen permeability between 1.63-12.31 cm·mm·Pa·day, and a limiting oxygen index (LOI) value of 28.10%-33.33%. Notably, the film demonstrates instant self-extinguishing behavior upon ignition and effectively inhibits bacterial growth when used in packaging.
