METHOD TO MANUFACTURE PACKAGING MATERIALS WITH ANTIMICROBIAL PROPERTIES BASED ON SILVER NANOPARTICLES Russian patent published in 2013 - IPC B65D81/24 

FIELD: packing industry.

SUBSTANCE: invention relates to packaging materials with antimicrobial properties specified by availability of silver nanoparticles. The invention objective is to develop packaging materials with low extent of silver nanoparticles migration into a product and highly efficient usage of silver nanoparticles. The method to manufacture packaging materials with antimicrobial properties on the basis of silver nanoparticles includes the following stages: placement of the packaging material or the item (packaging film, plastic containers) into a solution of silver nanoparticles; treatment of the packaging material placed into solution of silver nanoparticles with ultrasound; washing of the packaging material with silver nanoparticles with water or other dissolvent; drying of the packaging material; treatment of the packaging material with ultraviolet radiation.

EFFECT: development of packaging materials with low extent of silver nanoparticles migration into a product and highly efficient usage of silver nanoparticles.
